A Su-Kam Story · One of Our First Films

Inverter vs Generator: the Hindi video we made so every dealer and customer would finally get it

Before we could sell people a better idea, we had to teach it. So we made a film — in Hindi — to show India the real difference between an inverter and a generator.

“Su Kam Inverter vs Generator” — one of our earliest films, in Hindi. Script by Kunwer Sachdev; made with a professional agency, before YouTube was popular in India.
This was my own idea — at a time when nobody could believe a 10 KVA inverter was even available. No one in the industry had thought about it. We did it at Su-Kam, under my leadership.

You cannot change a habit you haven’t first explained.

When we started, the reflex across India was automatic: if you needed serious backup power, you bought a generator. Nobody stopped to ask whether there was a better way — because nobody had shown them one. So this became one of the very first videos we ever made, and we made it deliberately in Hindi, for the people who actually make the decision: the dealer on the shop floor and the customer in the home or business.

1 Why we put it on film — when our own team couldn’t

I was trying my best to educate our dealers — and our own sales and service people first. But the truth is, our sales and service teams simply weren’t able to reach the dealers and convince them about this product. The idea was too new, and a spoken pitch kept falling short.

So I made a decision: if our people couldn’t land the message in person, we would put it into a form that could land every single time. We brought in a professional agency, and I was directly involved in writing the script myself — because the explanation had to be exactly right, in the customer’s own language. It was made before YouTube was even popular in India, and uploaded there only two to three years later.

2 The difference the film showed — point by point

1 · Fuel & monitoring

Generator

  • No warning before the diesel runs out
  • Risk of short-measure or fraud when buying diesel

Su-Kam inverter

  • LCD display shows battery charge and the inverter’s health
  • No endless cycle of buying fuel
2 · Automatic change-over

Generator

  • Someone must start it on a cut and switch it off on return
  • In those seconds, computers and equipment shut down

Su-Kam inverter

  • Switches over instantly and automatically — no break
  • Your computer never even blinks
3 · Power quality & protection

Generator

  • Voltage fluctuation and signal distortion
  • Can damage costly electronics like computers

Su-Kam inverter

  • Pure sine wave power supply
  • On high grid voltage it shifts to a safe mode — protecting AC, fridge and computer
4 · Cost & savings

Generator

  • Burns a full ~3 litres of diesel an hour — even on a light load
  • The engine runs flat-out regardless of how little you draw

Su-Kam inverter

  • Costs about half the price of a 10 KVA silent generator
  • Draws only the power the load actually needs
~50%Lower upfront cost vs a 10 KVA silent generator
~3 L/hrDiesel a generator burns even at low load
40–50%Total savings over 2 years
5 · Pollution & maintenance

Generator

  • Smoke and heavy noise pollution
  • Regular maintenance — oil changes, filter cleaning
  • Vibration means it lives on the ground floor or outside only

Su-Kam inverter

  • Completely silent and pollution-free
  • Digital, no moving parts — practically no maintenance
  • Fits on any floor, anywhere inside the building
And the film ended where the ambition pointed: Su-Kam didn’t make one size. We built heavy inverters from 5 KVA all the way to 100 KVA — able to carry the full load of the delicate machines in homes, offices and even hospitals.

3 The first — and then everyone followed

Here is what I want on the record. When we started, nobody in the industry believed these inverters would sell — or even work — in India. A 5 KVA or a 10 KVA inverter as a real, sellable product simply wasn’t thought possible. We engineered it, manufactured it, and sold it across the country. And then, three to four years later, the whole industry copied us.

So let the credit sit where it belongs: the first 5 KVA and 10 KVA inverters in India were ours — built under my leadership, from my own idea — and I built them into a name the country came to trust: Su-Kam.

“I should be credited for India’s first 10 KVA and 5 KVA inverter — and for creating the brand Su-Kam.”
