Three decades after the first inverter, the problem has changed — from keeping the lights on to retiring diesel altogether. The method hasn't: find the problem, engineer the product, patent it, ship it at scale.
Taking the diesel generator out of the building
At Su-Vastika, where Kunwer Sachdev drives product strategy and innovation, the mission is blunt: remove diesel generators from hotels, offices, factories and housing societies — and replace them with silent, fuel-free lithium Battery Energy Storage Systems (BESS). Power switches over instantly; the lights don't even flicker. The proof point: India's first all-lithium hotel runs generator-free.
- Hotels, offices, factories and societies running generator-free
- Silent and fuel-free — no smoke, no noise, no fuel bills
- Proven in India's first all-lithium hotel
When the power cuts, no one gets trapped in the lift
A category-defining product in the Su-Kam tradition: the Lift Inverter and Emergency Rescue Device brings a lift gently to the nearest floor and opens the doors when grid power fails — running silently on lithium, with no diesel in the basement. The same instinct that created the Home UPS: find an everyday Indian problem everyone tolerates, and engineer it away.
- Lift reaches the nearest floor, doors open — no one trapped
- Works with lifts and escalators in any building
- Fit and forget — no fumes, no maintenance
Lithium power for big projects
From single homes to entire campuses — lithium battery banks that replace rooms full of ageing lead-acid batteries and noisy generators. Su-Vastika has filed 25 patents in clean-energy technology, ships 140+ products, and serves 10,000+ customers across 30+ countries. The patent-first engineering culture continues.
