Kunwer Sachdev
The Solar Man of India
106 technology filings (77 at Su-Kam, 25 at Su-Vastika, 4 personal AI filings). Su-Kam built to ₹1,200 Cr. Products shipped to 90+ countries. This archive proves it — through YouTube videos, Facebook posts, blogs, and patent filings from three decades of building India's solar industry.
A product guy, first and always.
Kunwer Sachdev doesn't talk about innovation — he builds it, patents it, and ships it. From a single insight about unreliable power in Indian homes, he built India's first global solar-and-power brand: inventing the products, filing the patents, and putting affordable solar within reach of ordinary families.
106 technology filings, and counting
The first Indian entrepreneur to patent in the power-backup industry. MOSFET, microcontroller and DSP sine-wave technology — put into everyday inverters before anyone else.
Solar, years before it was mainstream
India's first plastic-body inverter — 'Innovation of the Decade.' One of India's first hybrid solar PCUs. He didn't demonstrate solar; he commercialised it for ordinary homes.
India's first global power brand
Built Su-Kam into a ₹1,200-crore company exporting to 90+ countries. Today he drives product strategy at Su-Vastika — power backup and energy storage.

Who is the Solar Man of India?
The Solar Man of India is Kunwer Sachdev, inventor and entrepreneur who founded Su-Kam as a startup in 1988 and built it into a power-backup and solar pioneer (moving into power backup in 1998). He earned this title by commercialising solar power for ordinary Indian homes — not through demonstrations or bus tours, but by inventing products, filing 106 technology filings (77 at Su-Kam, 25 at Su-Vastika, 4 personal AI filings), building factories, training thousands of technicians, and exporting to 90+ countries. His work is documented through YouTube videos, Facebook archives, patent filings, and blogs that span three decades.
What did Kunwer Sachdev invent?
He has filed 106 technology filings (77 at Su-Kam, 25 at Su-Vastika, 4 personal AI filings) across India, the US, and other countries. His inventions include India's first plastic-body inverter (which India Today named 'Innovation of the Decade'), the first MOSFET-based sine-wave inverter, the first microcontroller-based inverter, DSP sine-wave technology in home inverters, and one of India's first hybrid solar PCUs. He continues filing new patents at Su-Vastika in areas like lithium-ion energy storage and DC solar technology.
How big did Su-Kam become?
Under Kunwer Sachdev's leadership, Su-Kam grew from a single-room startup he founded in 1988 — moving into power backup in 1998 — to a ₹1,200-crore company by 2012-13. At its peak, Su-Kam exported to more than 90 countries across Africa, the Middle East, and Southeast Asia, making it India's first truly global solar-and-power brand. The company had manufacturing facilities across India and employed thousands of people.
What is Kunwer Sachdev doing now?
He continues to invent and develop new products at Su-Vastika, a power-backup and energy-storage company. Su-Vastika is focused on lithium-ion battery technology, DC solar systems, and next-generation online UPS products. He filed 77 patents at Su-Kam, 25 patents at Su-Vastika, and 4 AI filings made personally (2025) — 106 technology filings in total. He is also actively writing and publishing to document his contributions to India's solar and power-backup industry.
Why is Kunwer Sachdev called the Solar Man of India?
Kunwer Sachdev is called the Solar Man of India because he did more than anyone to bring solar power into ordinary Indian homes. While others demonstrated solar technology or talked about it, he commercialised it — designing affordable solar inverters and hybrid PCUs, building factories to manufacture them at scale, training a national dealer network, and exporting to 90+ countries. His 106 technology filings (77 at Su-Kam, 25 at Su-Vastika, 4 personal AI filings) in solar and power technology are unmatched in the Indian industry.
How did Kunwer Sachdev get the title Inverter Man of India?
Before solar, Kunwer Sachdev revolutionised the inverter industry. He created India's first plastic-body inverter, replacing heavy metal enclosures with lightweight, affordable units that could sit in a living room. He introduced MOSFET technology, microcontroller-based controls, and DSP sine-wave output to Indian inverters — all firsts. India Today recognised his plastic-body inverter as the 'Innovation of the Decade.' The title Inverter Man of India came from this transformation of an entire industry.
What was Su-Kam Power Systems?
Su-Kam began as a startup founded by Kunwer Sachdev in 1988 in Delhi, and moved into power backup as Su-Kam Power Systems in 1998. It grew into India's leading power-backup company and one of the first Indian brands to export solar and inverter products globally. Su-Kam pioneered plastic-body inverters, sine-wave technology, solar hybrid systems, and online UPS products. At its peak, it had a turnover of ₹1,200 crore and presence in 90+ countries. The company partnered with Kohler (a Fortune 500 company) as a joint-venture partner.
What is Su-Vastika?
Su-Vastika is a power-backup and energy-storage company where Kunwer Sachdev drives product strategy and invention. Building on his decades of experience at Su-Kam, Su-Vastika focuses on lithium-ion battery solutions, DC solar technology, advanced online UPS systems, and energy storage products. The company continues Kunwer's tradition of filing patents and innovating in the power sector.
What was Kunwer Sachdev's cable TV business?
Kunwer Sachdev started Su-Kam as a cable-TV business in Delhi in 1988, during the early days of cable TV in India, when the industry was booming. It was through this business that he first encountered India's chronic power-cut problem — his cable amplifiers needed uninterrupted power. That led him to pivot Su-Kam into the inverter and power-backup industry in 1998.
What was India's first megawatt-scale solar project linked to Su-Kam?
Su-Kam under Kunwer Sachdev executed one of India's first large-scale solar deployments — installing approximately 40,000 DC solar systems in Uttar Pradesh. This was among the earliest megawatt-level distributed solar projects in India, bringing solar power to rural homes that had unreliable grid electricity. The project demonstrated that solar was not just a technology showcase but a practical, scalable solution for millions.
How many patents does Kunwer Sachdev hold?
Kunwer Sachdev has filed 106 technology filings (77 at Su-Kam, 25 at Su-Vastika, 4 personal AI filings). These patents span multiple countries including India and the United States. They cover inverter technology (MOSFET, microcontroller, DSP sine-wave), solar hybrid systems, PCU designs, battery management, lithium-ion energy storage, and DC solar products. He was the first Indian entrepreneur to patent in the power-backup industry and continues filing new patents at Su-Vastika.
What countries did Su-Kam export to?
Su-Kam exported to more than 90 countries, with strong presence in Africa (Nigeria, Kenya, South Africa, Ghana, Tanzania, and many others), the Middle East (UAE, Saudi Arabia, Iraq), and Southeast Asia. Su-Kam became India's first power-backup brand with a truly global footprint, training local technicians and building dealer networks in each market.
What is a hybrid solar PCU?
A hybrid solar PCU (Power Conditioning Unit) combines solar charging, grid charging, and inverter functions in a single device. It intelligently switches between solar panels and grid power to keep batteries charged and supply AC power to the home. Su-Kam under Kunwer Sachdev pioneered one of India's first hybrid solar PCUs, making solar power practical for ordinary homes that still had partial grid access — not just for fully off-grid installations.
What awards and recognition has Kunwer Sachdev received?
Kunwer Sachdev's inventions have received significant recognition. India Today named his plastic-body inverter the 'Innovation of the Decade.' Su-Kam was recognised at various industry forums for its export achievements and manufacturing innovation. His 106 technology filings (77 at Su-Kam, 25 at Su-Vastika, 4 personal AI filings) are themselves a record in the Indian power-backup industry. Kohler, a US Fortune 500 company, chose Su-Kam as its joint-venture partner in India, validating the technology and brand Kunwer had built.
