Su-Kam was the first Indian company to develop 3-phase inverter technology in India — told through engineer Vikas Garg, who joined as a fresher, was poached by a multinational, then came back for the culture of innovation.
Kunwer Sachdev, the Inverter Man of India and founder of Su-Kam, wrote opinion columns for the Times of India ‘Voices’ section on patents, EVs, renewable energy and HR — before stepping back to focus on his own work.
The Su-Kam Colossal 1P 10 KVA Solar PCU: a storage-first solar inverter for India’s commercial loads, with IGBT, DSP and a PWM charge controller.
Kunwer Sachdev on the Colossal Solar PCU — restless inventor energy, the unbroken chain from 2005 Solar PCU to Brainy Eco to industrial three-phase power plants, and why the whole industry followed.
How Su-Kam’s DT-6S six-stage charging — desulphation, soft start, bulk, absorption, equalization, float — extends inverter battery life. The charging software that built a brand.
Why an inverter beats a diesel generator — and how Kunwer Sachdev built India’s first 5 KVA & 10 KVA inverters at Su-Kam, told through the Hindi film he scripted to convince dealers and customers.
Solar was expensive and there were no subsidies. While others demonstrated it, Kunwer Sachdev commercialised solar — putting it on rooftops, in villages, and across 90+ countries.
Kunwer Sachdev on the mission that drives him today — making clean, affordable solar energy available to every Indian household, and how what he once argued for alone is now national policy.
The IBC makes the Committee of Creditors’ “commercial wisdom” supreme and almost beyond review. I sat in those meetings — sent out of half of them, watching bankers who never asked about operations.
Personal insolvency as a guarantor: I sold everything, paid the highest personal recovery in India, and still found no fresh start.
