How One Entrepreneur Changed India's Power Backup Industry Forever
How One Entrepreneur Changed India's Power Backup Industry Forever
As members of Su-vastika's team, we went through decades of trade publications, dealer records, and archived photographs — and discovered the full scale of what our mentor, Kunwer Sachdev Sir, the Solar Man of India, built for this industry and for the nation.

The India That Lived in Darkness
We at Su-vastika work alongside Kunwer Sachdev Sir every day. But it was only when we started going through old trade publications, dealer network records, and archived photos from Su-Kam's glory days that we truly understood the scale of what he built — and how fundamentally he changed India's entire power backup industry.
For decades, power cuts were a daily ritual across India. Homes, shops, and small businesses lost hours of productivity every single day. The solutions that existed — diesel generators and crude metal-box inverters — were expensive, unreliable, and dangerously inefficient. Inverters of the 1980s and early 1990s were little more than heavy iron transformer boxes with manual switchover. They hummed, they overheated, and they destroyed appliances with their rough square-wave output.
What the industry records confirm is that into this landscape stepped our mentor, Kunwer Sachdev Sir — whose remarkable personal story is itself worth reading — a young entrepreneur who saw not just a business opportunity but a mission: to give every Indian household reliable, affordable, and intelligent power backup. What followed was nothing short of an industry revolution.

A Technology Revolution — Before vs. After
When we examined the patent records and trade catalogues from that era, we were astonished to find just how many of the technologies that today's industry takes for granted originated from Kunwer Sir's work. He did not just improve inverters — he reimagined them. Every major technological leap in India's power backup industry can be traced back to his inventions and patents.
The Metal-Box Era
- Heavy iron transformer bodies
- Manual changeover switches
- Crude square-wave output
- No battery management
- Overheating and appliance damage
- No consumer branding
The Smart Power Era
- Sleek plastic bodies with modern design
- Microcontroller-based auto-switching
- Pure DSP sine-wave output
- MOSFET technology for efficiency
- Intelligent battery management
- India's first power backup brand
These archives show that the introduction of plastic-body inverters was revolutionary. For the first time, an inverter looked like a consumer product — something you could proudly place in your living room rather than hide behind a curtain. Microcontroller-based designs replaced crude relay circuits, bringing automatic switchover measured in milliseconds. MOSFET technology replaced bulky transistors, slashing energy losses and heat. And the crowning achievement — DSP sine-wave output — finally gave Indian homes power quality comparable to the grid itself.
These were not incremental improvements. Each one was a paradigm shift — and product demonstration videos in the video library show many of these technologies in action. Kunwer Sir — widely recognised as the Inverter Man of India — drove them all. His 76+ patents stand as documented proof of this relentless innovation. As his team today, we see the same inventive spirit at work in everything he does at Su-vastika.
The Branding Revolution
Before Su-Kam, the power backup industry had no recognisable consumer brand. Inverters were sold in local electrical shops with no branding, no warranty culture, and no after-sales support. What the dealer records from that period reveal is that Kunwer Sir changed the playbook entirely.
Su-Kam became India's first power backup brand — visible on billboards lining national highways, on delivery trucks crisscrossing the country, and on a fleet of branded service vans that brought professional after-sales support to doorsteps across India. We were astonished to find the sheer geographic reach of this branding effort when we reviewed the archived marketing materials — it was brand-building at a scale the industry had never seen.

The 7,000+ dealer network that Kunwer Sir built was not just a distribution channel — it was an ecosystem. Dealers were trained, supported, and empowered. The result, as industry records confirm, was that Su-Kam became a household name across urban and semi-urban India, with customers asking for inverters by brand name for the first time in the industry's history. As his current team, we continue to hear from dealers who recall those early days with pride.
From Garage to Global: The Su-Kam Scale
What started as a small operation grew into a ₹1,200 crore enterprise with a footprint spanning more than 70 countries. The export records and trade filings we reviewed paint a remarkable picture: Su-Kam did not just dominate the Indian market — it exported Indian power backup technology to Africa, the Middle East, and Southeast Asia, regions that shared India's power infrastructure challenges.

The Solar Pioneer
Even as Su-Kam dominated the inverter market, Kunwer Sir was already looking ahead. The product development records from that period show that he recognised early on that solar energy was not merely an alternative — it was the future. Under his leadership, Su-Kam developed India's first hybrid solar PCU (Power Conditioning Unit), a device that could seamlessly blend solar, grid, and battery power.
Solar installations reaching Indian rooftops — a vision turned reality
This was not rooftop solar for the wealthy. Kunwer Sir's mission — one that earned him numerous awards and industry recognition — was to make solar accessible and affordable for ordinary Indian homes and businesses. The hybrid PCU meant homeowners did not need to choose between solar and grid — the system intelligently managed both. It was this vision that earned him the title Solar Man of India. As members of his current team, we see this same commitment to solar accessibility driving every product we build at Su-vastika today.
The Next Chapter: Su-vastika
Innovation does not stop — and we at Su-vastika are living proof of that. Through Su-vastika, Kunwer Sir is building the next generation of power solutions, centred on lithium-ion battery technology and advanced solar integration. Where lead-acid batteries defined the last era, lithium-ion defines the future: lighter, longer-lasting, faster-charging, and far more environmentally responsible.

The Su-Kam legacy continues through Su-vastika
Working alongside our mentor daily, we see how Su-vastika's product line represents everything Kunwer Sir learned from building Su-Kam — refined, modernised, and designed for an India that is rapidly moving toward renewable energy. The same philosophy that these archives document holds true today: cutting-edge technology made affordable and accessible to the masses. It is a privilege for us to carry forward this mission under his guidance. Read more perspectives on this journey in the blog archive.
