Solar Man Of India: One of the finest innovators, marketers, motivational speakers, and visionary businessmen of our time is Kunwer Sachdev, founder of Su-Kam Power Systems, India’s premier provider of power solutions. Kunwer Sachdev, like Thomas Edison, has cemented his place in history by founding one of the most admired Indian businesses and revolutionizing the power backup sector.
Under the guidance of Kunwer Sachdev, Khushboo Sachdev launched a new business called Su-vastika
She created this new company with financial assistance from Kunwer’s friends and family.
Her own struggles compelled her to do so, and there was no turning back after that.
Success Story: The introduction of electricity transformed our way of life for decades, but the growing number of shortages and their lengthening frequency have made another invention necessary. Behind the scenes, a game changer with a non-technical background was putting in his hard work and commitment as this awful state of electricity deficit persisted for years. Kunwer Sachdev is widely known as Solar Man of India for his contributions and became the face of the power backup sector in India and the brains behind Su-Kam, one of the most progressive and rapidly expanding businesses in the country.
Kunwer Sachdev: Rags To Riches
A real “rags to riches” story, Kunwer Sachdev was raised by a railway clerk in Delhi’s Punjabi Bagh neighborhood while dreaming of starting his own company one day. Following his graduation from college in 1984, he started working full-time in his brother’s pen business. He attended a public school where the curriculum was taught in Hindi. He quickly recognized the potential in the field of power backup because he was a visionary from an early age. Due to the challenges of a severe power deficit, he made the decision to shut down his cable TV business and start Su-Kam in 1998. He has since launched numerous additional enterprises, but he has maintained the same Su-Kam throughout his entrepreneurial career for all of his ventures. But where did the name Su-Kam originate? The initials of his daughter’s name, his name, and the names of his future children were once combined in Kunwer’s mind to form the name of his company.
Solar Man of India: The Innovator and Visionary
Su-Kam- The Unmatched Product
He had a difficult time raising money for his business, so it surprised him when clients returned his first 100 inverters due to issues. Never one to give up, he improved his invention and fixed all the flaws to make it better than anything else on the market. Before making cold calls to prospective new clients, he first spoke with a number of his cable TV clients. Realizing that selling to people directly would not help him grow his business, he started approaching dealers and wholesalers. The majority of producers quickly realized that Su-Kam was unmatched in terms of product quality and price, even though the market was already crowded at the time.
Su-Kam: Monopoly
They were therefore compelled to accept Kunwer’s proposals in order to become his company’s initial partner. Soon after, Su-Kam became the first company in the industry to start exporting its products to the aforementioned markets. Kunwer started expanding his business during this time by visiting other nations. Kunwer surmounted new barriers brought on by governmental restrictions, corporate traditions, legal frameworks, and rivalries to establish Su-Kam as a household name in many of these countries. For his achievements, Kunwer Sachdev was given various awards, including the “Bharat Shiromani” and the Ernst and Young “Entrepreneur of the Year” titles.
Solar Man of India: The Innovator and Visionary
Su-Kam Bankruptcy
Su-Kam Power Systems Limited filed for bankruptcy as a result of a string of tragic events, and Kunwer Sachdev was forced to quit the company he had considered his own for 32 years of his career and distance himself from it after getting involved in various legal disputes. The man who altered the landscape of India’s power backup industry was forced to fight his toughest battle. The business was closed for two years (April 2019-April 2022). There was no help available. Nobody was answering the phone calls or responding to emails. Dealers and customers both suffered greatly during this time.
Khushboo Sachdev: A Blessing In Disguise
Customers, distributors, suppliers, and other company associates were left with a void following Kunwer Sachdev’s departure from the business that he started and oversaw from its beginning until 2018. Customers and dealers both suffered because they had unsold goods and services on their hands, and there was no way to resolve any warranty claims from customers. After great effort and difficulty, Kunwer Sachdev’s wife, Khushboo Sachdev, stepped up to assist him in these circumstances.
Su-Vastika And The Power Woman
Under the guidance of Kunwer Sachdev, Khushboo Sachdev launched a new business called Su-vastika with a lot of assistance and support from friends and family. She created this new company with financial assistance from Kunwer’s friends and family despite having no prior experience in business management. Her own struggles compelled her to do so, and there was no turning back after that. She met people, made plans, and was aware of every step. Although she was inexperienced, she started Su-vastika with a team thanks to her tenacity and enthusiasm. She made do with her children and elevated Su-vastika.
The brand experience, according to Kunwer, begins inward and moves outward from there. It is for this reason that, on the one hand, he provided fresh challenges for his employees to advance their abilities. On the other hand, he observed all the holidays with fervor and took several steps to strengthen the bonds among his team members. The establishment of one of the most admired Indian firms, which revolutionized the power backup market, has earned Kunwer Sachdev his place in history, just like Thomas Edison did. And he is not done yet.

Understanding IBBI Guidelines for COC without Valuation Criteria
IBBI Guidelines for Committee of Creditors: A Step Forward, But Valuation Concerns Remain Critical, Understanding IBBI Guidelines for COC without Valuation Criteria.
The Insolvency and Bankruptcy Board of India (IBBI) has recently unveiled comprehensive guidelines for the conduct of Committee of Creditors (CoC) in insolvency proceedings. This development follows a directive from the Delhi High Court in the case of Kunwer Sachdev founder Su-kam Vs IDBI Bank and others, which mandated the IBBI to establish clear rules for CoC functioning.
Sukam Solar
The new guidelines aim to enhance transparency, accountability, and efficiency in the insolvency resolution process. They encompass a wide range of aspects, including CoC composition, meeting conduct, decision-making, and information dissemination. By providing a structured framework, the IBBI seeks to strengthen the role of CoCs in maximizing recovery for creditors and ensuring fair treatment of all stakeholders.
Understanding IBBI Guidelines for COC without Valuation Criteria
While these guidelines represent a significant stride in regulating the insolvency process, a crucial oversight persists: the valuation of the insolvent company. This was a focal point of the case that prompted the court’s intervention. The absence of clear and standardized valuation methodologies can undermine the effectiveness of the insolvency resolution process, potentially leading to asset undervaluation and suboptimal outcomes for creditors.
A critical element missing from the new guidelines is the emphasis on the initial valuation conducted by valuers when the Resolution Professional (RP) takes over the company. This valuation serves as a crucial benchmark to assess the entrepreneur’s intentions – whether they managed the company with fraudulent intent or otherwise. By incorporating this initial valuation as a primary consideration for CoCs, the guidelines could mitigate undue blame placed on entrepreneurs for value erosion when they were unable to maintain the original valuation.
Understanding IBBI Guidelines for COC without Valuation Criteria
It is imperative that the IBBI prioritize the development of robust valuation standards to complement these new CoC guidelines. This, coupled with the emphasis on the initial valuation, will ensure that the insolvency framework comprehensively addresses the challenges faced by creditors and other stakeholders, ultimately contributing to a healthier business environment.
IGBT, or insulated gate bipolar transistor, is a power semiconductor device used in various applications, including industrial UPS. IGBTs offer several advantages over other types of power devices, including IGBT-Based Heavy Duty UPS & It’s Reliability
IGBT-Based Heavy Duty UPS & It’s Reliability
High efficiency: IGBTs can be switched quickly, leading to lower losses and higher efficiency.
Fast switching: IGBTs can switch on and off very quickly, which makes them suitable for high-frequency applications.
Wide input voltage range: IGBTs can operate over a wide input voltage range, making them suitable for various industrial applications.
Rugged construction: IGBTs are typically very powerful and can withstand harsh environments.
These advantages make IGBTs an ideal choice for use in heavy Duty UPS/Industrial UPS. In Industrial /Heavy Duty UPS, IGBTs convert AC power from the mains into DC power, which is then stored in batteries. In a power outage, the UPS uses the stored DC power to provide uninterrupted AC power to critical loads.
The use of IGBTs in heavy Duty/Industrial UPS offers several benefits, including:
Increased efficiency: IGBTs are more efficient than other types of power devices like MOSFETs, which can significantly save energy costs.
Improved performance: IGBTs can switch very quickly, which can improve the performance of the UPS in terms of response time and transient suppression.
Increased reliability: IGBTs are typically very reliable and can withstand harsh environments compared to Mosfets
IGBT-Based Heavy Duty UPS & It’s Reliability
As a result of these benefits, IGBTs are becoming increasingly popular in industrial UPS applications.
Here are some specific examples of the importance of IGBT in industrial UPS:
Increased efficiency: IGBT-based heavy-duty UPS systems are typically more efficient than other power devices. This is because IGBTs can switch quickly, reducing losses and improving efficiency.
Improved performance: IGBT-based UPS systems typically have faster response times and better transient suppression than other power devices. This is because IGBTs can switch very quickly, which allows them to respond to changes in a load more rapidly and suppress transients more effectively.
Increased reliability: IGBT-based UPS systems are typically more reliable than other power devices. This is because IGBTs are typically very rugged and can withstand harsh environments.

Demystifying High Frequency vs Low Frequency Inverters/UPS
Two kinds of commonly used Inverters/UPS; High Frequency and Low Frequency. In common man’s words, High-frequency Inverters/UPS are those without Transformers, and Low-Frequency Inverters/UPS are those with Transformers.Demystifying High Frequency vs Low Frequency Inverters/UPS
But there is more to it. Let us understand……..
The main difference between High-frequency and Transformer-based Low-Frequency Inverters/UPS is the frequency at which they operate. High-frequency inverters/UPS operate at 20,000 to 100,000 Hz frequencies, while transformer-based Low-frequency inverters/UPS operate at 50 or 60 Hz frequencies. Transformer-based Inverters are more expensive and bulkier compared to High-Frequency Inverters/UPS. They are also more tolerant of higher and lower voltage fluctuations. However, they are larger and heavier and less efficient than high-frequency inverters. Chinese players mainly dominate High-frequency Inverters. However, Low-frequency Inverters are majorly made in India.
High-frequency Inverters have several advantages over Transformer-based Inverters, including:
Smaller size and weight
Higher efficiency
Better noise performance
Wall hanging models
However, High-frequency inverters also have some disadvantages, including:
They don’t have isolation between the Neutral and Line
More complex circuitry
Less tolerant of voltage fluctuations and spikes, and surges
Difficult to repair
How to choose between High-frequency Inverter/UPS or Transformer based Inverter/UPS?
The best type of inverter for a particular application will depend on the specific requirement of that application. For example, a High-frequency inverter may be the best choice if size and weight are important considerations. But if there is high and Low-voltage fluctuation, spikes and surges in power supply at the site, you need Transformer based Inverters to protect your Inverter and appliances. For Heavy, Industrial, Mechanical, and Induction loads, Transformer based Inverters are always recommended due to their power to absorb voltage fluctuations and surges. Expensive and Sensitive Electronics devices are always at risk with High-frequency Inverters.
Why is a Transformer important in an Inverter/UPS?
Isolation plays a major role in the functioning of the Inverter/UPS during the charging period as there are voltage fluctuations, High and low voltage happening during that period which typically burn the MOSFETs in high frequency based Inverter/UPS.
Another challenge is weak Neutral in a few areas, which has become a major cause of MOSFET burn in high-frequency Inverter/UPS as there is no transformer to isolate neutral and line from the grid Power.
Since the High frequency based Inverter/UPS is working on a High frequency, they interfere some time with the TV or other running equipment, as the high frequency is transmitted around sensitive types of equipment like TVs, and one can see lines appearing in the TV when the Inverter/UPS is working.
The High-Frequency Inverters have no issues in Developed countries where the Grid power is very stable, like the USA, Britain, France, Russia, Denmark, Germany, Japan, Belgium, etc.
But suppose the same high-frequency inverters are installed in African countries like Nigeria, Sudan, Uganda, Kenya, Congo, Ethiopia, Botswana, South Africa, and Tanzania. In that case, Middle Eastern countries like Yemen, Syria, Iraq, and Lebanon or South East countries like Bangladesh, Pakistan, and Sri Lanka, wherein there is high and Low voltage fluctuation, then there are very high chances of MOSFET failure and other circuitry problems.
The transformer acts as an Isolator and balancer in the Mosfet-based circuitry, which creates the Isolation between the Line and neutral, so any disturbances on neutral or line can be grounded.
Also, the switching or transfer time can be lower for transformer-based Inverters/UPS. In this case, Computers and TVs can work uninterruptedly.
The transformer-based Inverter can be automatically designed for 50 and 60-Hz switching, which is impossible in a high-frequency Inverter/UPS. In case of High or Low voltage fluctuations, the burning of MOSFETs can happen in High frequency based Inverter/UPS.https://suvastika.com/our-smart-ups-having-50-and-60hz-automatic-switching-technology/
In case of multiple times Overload and short circuit, there is a high probability of Mosfet burns in high frequency based inverter/UPS.
Even in the installation of Online UPS based on High-Frequency technology, the same problem happens, and that’s why they are advised to install a separate external Isolation transformer alongside the High-frequency Online UPS.
The same concept is followed for the Solar grid feed Inverter installation, and the Isolation transformer is compulsorily installed in large buildings.
The Transformer based UPS with ATC feature has the advantage over the High Frequency based Inverter/UPS.
Here is a Table summarising the key differences between high-frequency inverters and transformer-based inverters:
Feature
High-Frequency Inverter
Transformer-Based Inverter
Operating frequency
20,000 to 100,000 Hz
50/ 60 Hz
Size and weight
Smaller and lighter
Larger and heavier
Efficiency

Higher
Cost
Less expensive
More expensive
Complexity
More complex circuitry
Simpler circuitry
Tolerance of high Surge current for running heavy motors etc.
Less tolerant

Lower
Ultimately, the best type of inverter for a particular application will depend on the specific country and the stability of the Power Grid.
Generator compatibility with home inverters/UPS is critical to ensure the generator’s output waveform is compatible with the inverter’s input requirements. If the generator’s output waveform is not compatible, it can damage the inverter and/or the appliances connected to the inverter. Another critical parameter is the Frequency of the generator, which can play considerable havoc on the Load connected through it. Hence, Inverters/smart UPS need protection for High Voltage, Frequency Limit and waveform compatibility. If these factors don’t match, the inverter/Home UPS will not pass the power through it when the generator switches on in case of a power failure. Inverter/Home UPS will keep running without recognizing the generator power.Why Generator and Inverter Compatibility Matters
Why Generator and Inverter Compatibility Matters
There are two main types of generator output waveforms:
Modified sine wave: This is the most common type of generator output waveform. It is less expensive to produce than a pure sine wave, but it can be more problematic for some appliances.
Pure sine wave: This is the highest quality type of generator output waveform. It is more expensive to produce than a modified sine wave, but it is compatible with all appliances.
Inverters also have two main types of input requirements:
Modified sine wave: Some inverters can accept a modified sine wave input. However, this is not recommended, as it can reduce the lifespan of the inverter and/or the appliances connected to the inverter.
Pure sine wave: All inverters should have a pure sine wave input. This is the only way to ensure that the inverter and the connected appliances will not be damaged.
The Output Voltage from the Generator must be within safe Limits of 140 V to 275 Volts.
The frequency coming from the Generator has to be within limits, say 47 to 52 Hz.
The generator’s output Power has to be higher than the power of the Inverter/UPS connected to the Generator.
In Su-vastika”s UPS we have given the Wide UPS mode, which works on the Wide voltage range, so even if the Generator is giving as low as 100Volts to as high as 280 volts, it will let it pass in that mode, especially the UPS with ATC model.
For the Frequency range, we have designed our UPS to the 43Hz to 55 Hz to bypass the frequency, which is an extensive range to perform for any generator
one can see in the mobile app while running the generators and Incase the generator shoots the voltage limit or frequency range. The UPS will take the protection and not bypass the higher or lower voltages and higher or lower frequency, which can harm the appliances attached to the generator and inverter/UPS.
Why Generator and Inverter Compatibility Matters
Therefore, matching the generator’s output waveform to the inverter’s input requirements is essential. If you are unsure about the compatibility of your generator and inverter, consult a qualified electrician.
Here are some additional things to keep in mind when choosing a generator for your home inverter:
The generator’s wattage must be sufficient to power all the appliances you want to connect to.
The generator’s output waveform must be compatible with the inverter’s input requirements.
The generator must be properly sized for your home’s electrical needs.
The generator must be placed in a safe location away from your home.
By following these guidelines, you can ensure that your generator and inverter will work together seamlessly to provide you with reliable backup power otherwise one will face issues with the Inverter/UPS as Inverter might not switch when the mains power fails even when the generator is started as if the generator does not match the conditions the inverter will not let the power pass through it.
IBBI – A Law Impacting Entrepreneurs and Make In India Campaign
The new law, Insolvency and Bankruptcy Code made with excellent intention by the Narender Modi government,IBBI – A Law Impacting Entrepreneurs and Make In India Campaign as he has the vision and the guts to change the country. Still, the law’s implementation is full of flaws, regulations keep changing every six months, and the intention with which they were made was never achieved. Instead, it became the tool for the destruction of existing Indian companies, as the companies that the Indian entrepreneurs built through blood and sweat were ruined with a single stroke of admission into the NCLT. The banks also lose their investment. The primary intent of making this law was to revive the companies and make them run if they were in trouble, then preserve their value and run them so that employment is not lost, banks can make their investments safe, and suppliers and other stakeholders can get the value. Still, if we see the data until today, most companies admitted to the NCLT have gone into liquidation, where entrepreneurs, banks, employees, suppliers, distributors, and customers suffer huge losses.
The Domino EffectThat Harms Everyone.
One big company going into liquidation creates a situation where a few suppliers and distributors also go bankrupt, which no one notices.
This law was enacted with the right intention by the BJP government, but who were the people involved in making these laws? Were they entrepreneurs, politicians, bureaucrats, advocates or academicians or bankers? In India, when the rules are being made, generally some people are chosen to make the committees who have hardly any knowledge about those subjects, or people who are celebrities in these fields are made members and don’t have time to look into the nitty gritty of that particular law point. So this law was imported from the United Kingdom and enacted, and then Indian thought was mixed with this law.
If we see the complete history of this law, we know that it keeps changing every six months. Changes were made randomly, and still, more lacunae are found out later, and changes keep happening, but a lot of money from banks is already lost. Entrepreneurs are also ruined, and so many people are suffering. However, even today, the mess is still there, courts pinpoint the areas where lawmakers did not clear so many aspects of the law, and the grey areas are left. The ultimate objective of this law didn’t achieve its purpose, and the destruction was rampant. Initially, banks were also very enthusiastic about quick recovery from this law but also realized it was a destruction of their loan amounts. As the law progressed, bankers were also punished by being put behind bars, and the bankers stopped disbursing loans. Now another challenge started for the government: bankers were not ready to give loans, and the government tried to convince them that no action would be taken against them. Most entrepreneurs were put behind bars, and the CBI, ED, and SFIO all started the harassment for the same cases. First, CBI came, then ED, and then SFIO, asking the same questions repeatedly.
Who were to decide that the loans they classified as bad loans were bad because, one day, the RBI changed the definition of bad loans to put a spanner in the running economy, which used to have easy money available? Businesses were growing fast, and maybe a few entrepreneurs and bankers were taking advantage of the systems that could have been improved by an alternative method. Implementing this law at a large scale without due diligence was a big goof-up. Still, one fine day, everything is changed without adequately considering what will happen if we restructure the system overnight. What will happen to Make in India companies that could be destroyed with this law? Are we prepared because there were many agencies for implementation, and they were not prepared and trained to handle such a situation?

The major challenge was determining who would run the company during the moratorium period. Their things were taken very lightly, which became one of the primary reasons for failure. The government created a post for a resolution professional and made an exam for the professionals to come and clear the exam and become the RP. All professionals who were not settled in life or people who were young and inexperienced cleared the exams and became RPs.
Big 4 And the Corruption
The next big goof was when those big four jumped into the arena, seeing the massive potential of making money, and they put these RPs on their rosters, or some other agencies that were doing similar businesses came to the fore and hired these RPs.

The corruption started significantly as the RPs gained experience, and they never ran companies. Even the big four never ran the companies and lacked the entrepreneurial skills and expertise to run the companies. Even the lawmakers who enacted the laws did not know how the companies were run. In the company changing management is not possible, and if done overnight, the company can be finished; this is a very tricky situation. That’s why entrepreneurs are struggling to keep their flock together who know their job, and everything is not black and white and governed by the laws that happen wherever the government functions runs on the system and processes whether they are being adhered to or not.
So when they enacted the law, the first thing was to publish an advertisement in the newspapers that the company had gone into liquidation, so please file claims against whoever had to take money from the company.
Now, people running the companies know that one day the company’s valuation will take a big dip as soon as this announcement is made in the media because all the stakeholders will stop investing money, time and effort as they become insecure about the company. The company will take a big hit. All the stakeholders or customers get a jolt about what will happen next to the company.
The customers are swayed away by the competitors with bad stories. Employees become insecure, and suppliers worry about what will happen next.

The IBBI guidelines do not mention the handover of the company or employees or procedures for dealing with an existing entrepreneur and the employees, suppliers, distributors, or customers. How to run the current concern as a going concern, and everything is left to the RP and his team, supported by the team provided by the companies that have hired the employees, and now the loot maar starts. Banks generally do not want to invest, and now the company that is at this stage and having cash flow issues and other issues is paying the bills of RP and his team, which can’t contribute to running the company. They only try to scare the promoter and employees with their powers. Most good employees leave the company, and a significant portion of expenses are done in the name of following processes and procedures. The company becomes broke in no time. The company which goes into the NCLT already has a very tight fund flow position, and the moment they enter, they start charging the company for various people and processes, which becomes an enormous burden on the company, which is already stressed and most of the time banks don’t invest money to save the cash crunched company. These big four make fat bills in the name of processes, people and legal expenses, which become the sure-shot recipe for a company closing down and going for liquidation. Once the running company closes down, its value is eroded completely. This has happened to most of the companies which went into the NCLT. First, the running companies are closed down by these people and then sold to buyers at 5% to 20% of the company’s value on the valuation they took over. The valuation of the company is a standard procedure in which they have to get it done by two valuers; one should get the data from the IBBI on how many companies are sold at the same valuation or more when these big fours entered the company if they have eroded the valuation than who is responsible that. Is the entrepreneur responsible for that destruction as he is kept out of the company from the day these firms take over? The RP and these big fours don’t involve the entrepreneur even in the valuation process and don’t give him valuation reports in the name of the law. Still, once everything is sold at throw-away prices, they demand the rest from the entrepreneur.

Why keep the promoter out of the valuation is a big question mark, so his company is taken over. He doesn’t get a chance to show the valuer what he has created as the promoter is the first and the last person in the small and mid-size company to tell the valuer what is lying where and how much it can be valued and to whom can be sold but that not the valuer’s concern. But not involving the promoter in the valuation and not telling him the valuation after it is done is a fundamental right being denied to the entrepreneur.
How Are Suppliers Affected?
Even the suppliers face the next significant brunt as the law stipulates that the supplier can’t get the money for his previous supplies. He can get only new money against the new supplies, which makes him pissed off and not ready to cooperate with the management, and the administration is unique. It can’t give him any commitment or assurance. So the supplier is insecure, employees get insecure, and the promoter is put in a legal tangle where he is a defaulter. He is answerable to every government agency in this world. He is accountable to RP, the banks, forensic auditors, and later to the CBI, ED, and SFIO. Now he will become old, answering to all these agencies, and will be harassed till his death.
The purpose of the law was to run the companies, which are stressed by the promoters, and give another chance to the champion to make another company and add value to society, but what came out was that the promoter was fighting his legal battles and lost his reputation. The agencies and banks also didn’t get their dues. These same agencies and countries also harassed bankers as a whole. Once the CBI raid is done, the promoter’s name and company names tell how much money he has embezzled and not what he has created, such as what brand or what kind of factories and human resources he has trained, how much tax revenues he has created for the country, how much exports he has created, or how many establishments with knowledgeable people he has built around him.
Let us take the case of Su-Kam, and when they entered the company, RP got the valuation done, which was the process part, he got the value done from two valuers, and it was approximately 300 Cr which was higher than the loan amount of that time. This valuation was done by the RP, keeping me in the dark and repeatedly, they didn’t disclose the valuation to me, which is a big question mark for the IBBI process as the banks and IBBI for the RP and the agency which ran the process whether these people sold the company more than its valuation or not. If not, then it’s a significant loss they have done to the exchequer as they could not do the right job. We are losing on a critical point as this should become the assessment point for the banks and IBBI. The bank was overdue on the day of the company going to NCLT at approximately 260 Cr, and the banks filed a complaint with the CBI that I owed them 260 Cr, and CBI filed an FIR against me and started proceedings against me. I have a question to ask from the banks and IBBI why didn’t they file the same complaint against the RP and agency handling the liquidation about how much loss they created for the exchequer by selling the company at such a low price and so many people lost the jobs and suppliers got ruined. Dealer distributors lost money in warranties, and a few closed their shutters. Where is the company valuation they took over from me and valued at Rs 300 Cr? If the company’s valuation was 300 Cr after the advertisement of liquidation, imagine they had done the valuation before the ad in the newspapers. It would have been 500 Cr plus. This has no significance in the whole process while the company is in the NCLT, as valuation is only done as a formality. In contrast, it should be seen as an entrepreneur’s honesty.
The government spent so many crores on skilling but couldn’t get jobs for the people, but here, entrepreneurs hired people without any skills and made them talented. So many people went abroad with the help of the entrepreneur’s professional setup. Now that the kids of entrepreneurs are watching their parents go through these uncertainties and bad times where all the agencies are after you, CBI, ED, SFIO, and legal cases in DRT, NCLT, high courts, or local courts being harassed by cheque bounce cases by the customers and suppliers that the company bounced. All the customers are filing cases in local courts against the company and the entrepreneur, and the company has a moratorium, but the entrepreneur has no moratorium. So, we keep going from one court to the other, fight our endless cases, and die fighting these cases, and people who are close to us will never dare to do business in this country. This law has created fear among the entrepreneurial community, as the question is not whether companies will prosper or fail but whether your business will fail in India. If you have taken a loan from the bank, then the failure of your business will become a battle for an entrepreneur, as his case will be classified as a fraud account by the banks, and his case will be handed over to the CBI for investigation. The same harassment will continue by the other agencies. Since these agencies don’t have the time to investigate such a massive load of cases, the investigation continues, and maybe till our deaths, these cases will not be decided. So, this is the real story of a failed business entrepreneur. I will die with the blame that I made a significant loss for this country by taking loans from the banks, and I’m a fraudster in the eyes of the common public. Every day such news appears in the newspaper that the entrepreneur made losses to the bank to the tune of 1000 crore or 2000 crore, and the ordinary person does not understand the meaning of this news. But there is not a small column in the news that states that when banks take over the company, then what was the company’s market value, and the rest of the amount is a loss to the banks and not the complete loan taken from the banks is a loss. The banks and the system make the rest of the loss.
Many companies that were examples of Make in India got perished and went into liquidation, and the expertise that the entrepreneurs had created went down the drain. It is a significant loss for the nation as a whole. Su-Kam is one example of the destruction done by this law, as it went to the NCLT in April 2018, and Kotak Bank was ready to give me an investment in 2019. They committed 250 crores as an investment into the company, which was refused by the bankers sitting in various courts, and the su-kam case went on in different courts. The ultimate banks received eight crores in principal out of 260 crores, and the company was sold for 50 crores. Out of 50 CR banks, while running the company, PWC already had loans from the supplier and made bills for running the company, which they couldn’t run for more than one year, and for legal expenses and salaries due to the employees, etc.
So the result is that the company was valued by them when they entered after RP loved NCLT by two valuers at Rs 300 cr, and the banks got only eight cr, for which probably the legal cost incurred by them will be more than that. I’m sure. The entrepreneur destroyed suppliers and got nothing; employees lost their jobs, dealer distributors suffered losses financially and reputationally, and the customers didn’t get service for the product they bought. Then who got benefit out of this saga?
The Supreme Court has set aside the fraud declaration by the banks as a wrong step, and we have already lost reputation, health, and confidence because of the fraud declaration. CBI registered a case against me and harassed suppliers, dealers, distributor employees and me for more than two years, and CBI also spent resources investigating the case. They called at least 100 distributors and suppliers employees, and so many were connected to the company that they were harassed. So this one case is study material for the nation, showing that a small wrong can destroy so much for so many. How will I get my pride back that I’m not a fraudster and I had a role in building the nation by creating a company which provided direct employment to 3000 people and made technology patents, kept China away from the Inverter Industry, created exports against China created RnD in the industry. They built world-class factories in India worth visiting with all the latest machinery and infrastructure sold at a meagre amount of 50 Cr. My one battery factory was constructed at an investment of 80 Cr. All my factories’ brand and distribution network was sold in Corona Times, and the buyer deposited money for two years when the properties alone could be valued at 200 Cr. Is this the fair system, and I’m asked to pay for the rest of the amount where the interest amount continues every day, and my loan of 260 Cr has become 550 Cr and will continue to add every day?
Can the Supreme Court or any other court in India get me back my five years of fighting my battle rather than decorating myself for creating an industry where I developed export of inverters rather than importing the inverters? I stopped China from entering India’s inverter industry. In the last five years, all Chinese solar inverters are ruling the market, for which my R&D had already developed the technology, which has gone to waste.
The recent development is that my RP and liquidator were found guilty in the Su-kam Power Systems Ltd. case, barred from the practice, and imposed a fine. My concern of Sharing concerns about IBBI law is not my issue only. Many companies and entrepreneurs have faced the same fate but are silent.
I thought I had the right to ask these questions and write for many entrepreneurs facing similar challenges.
