AI server rooms are the next great power guzzlers — and they’re going DC. In 2016 I ran Su-Kam’s R&D building entirely on solar DC, cutting office lighting from 1,200 W to 408 W — the biggest power saving India almost led.
Most inverters stop charging when the mains drops below ~130V. The Su-Kam Falcon Plus 1100 charges your battery to full at as low as 90V — built for India’s low-voltage homes, with six-stage charging and an 8 ms switchover.
The Su-Kam Brainy Eco 1100 / 12V is an intelligent solar home inverter — a Solar PCU that puts free solar first, never overcharges the battery, and works with almost any battery from 18 to 150 Ah.
The Su-Kam Intelli S 40 KVA / 360V is a true online double-conversion UPS that runs the most sensitive medical loads — up to 22 X-ray machines — on clean, isolated, solar-fed power with zero switchover.
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.
