From 40,000 rural homes in Uttar Pradesh to schools in Rwanda and street lights across Gabon — Kunwer Sachdev revisits ten real Su-Kam solar projects, preserved from the official Su-Kam Solar Facebook archive.
The Su-Kam Brainy Hybrid GTI combined a UPS, a Solar PCU and a grid-tie inverter in one box — a 3-tier brain that runs your load, charges the battery, and exports surplus solar to cut your bill, while still giving backup during a power cut.
The Su-Kam Colossal 3P 30 KVA / 360V Solar PCU — a patented (No. 2651/DEL/2007) three-phase, solar-first power plant that can run MRI machines, CNC lines, fuel pumps and more, with six-stage charging and built-in solar.
The Su-Kam Colossal 3P 40 KVA / 360V Solar PCU — a patented (No. 2651/DEL/2007) three-phase, solar-first power plant that can run MRI machines, CNC lines, fuel pumps and more, with six-stage charging and built-in solar.
In 2014 Su-Kam built India’s first 100 KVA three-phase Solar PCU — a machine that runs 14 CNC machines on solar. Deployed for the Assam Rifles, demonstrated on a ‘Power on Wheels’ truck, and later exported to Nigeria and Kenya.
Ten years after Su-Kam built India’s first 4-star inverter, home inverters and lead-acid batteries still have no mandatory BEE efficiency standard — while every AC, fridge and fan does. An open letter from Kunwer Sachdev.
The Su-Kam Falcon HBU — India’s first high-frequency inverter and first 4-star Home UPS, 90% efficient, patented, with UPS switchover and a patented heat-resistant plastic body in multiple colours.
Su-Kam built India’s first high-frequency inverter — my pet project that failed twice before we won a 4-star BEE rating. The story of Sivarajan Ramachandran, the engineer I picked from IIT Delhi and made my CTO.
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.
