Two machines that retire the generator
Battery Energy Storage System (BESS)
We take the diesel generator out of the building — for good.
- Hotels, offices, factories and societies run generator-free
- Silent and fuel-free — no smoke, no noise, no fuel bills
- Power switches over instantly — the lights don't even flicker
- Proven in India's first all-lithium hotel
Lift Inverter & Emergency Rescue Device
Lift backup that keeps people moving when the power goes.
- No one gets trapped — the lift reaches the nearest floor, doors open
- Works with lifts and escalators in any building
- Runs silently on lithium — no diesel in the basement
- Fit and forget — no fumes, no maintenance

Is a LiFePO4 Inverter Battery Safe? Can It Explode?
Is a LiFePO4 inverter battery safe? Unlike the NMC cells behind phone and EV fires, LiFePO4 resists thermal runaway to ~270°C, releases no oxygen, and a BMS cuts faults first. What actually causes battery fires — and the checks to make before buying.

Frequently Asked Questions
What products does Su-vastika make?
Su-vastika manufactures lithium (LiFePO4) inverters and Home UPS, double-conversion Online UPS, heavy-duty IGBT UPS, solar hybrid PCUs, lithium battery banks, Battery Energy Storage Systems (BESS), and lift Emergency Rescue Devices (ERD) ranging from 850 VA to 500 KVA.
What is a lithium inverter and how is it different from a normal inverter?
A lithium inverter is a power-backup unit that pairs an inverter with a built-in LiFePO4 lithium battery instead of a lead-acid battery. It charges faster, lasts up to 6000 cycles, needs no water topping or maintenance, runs cooler, and delivers far more usable backup in a lighter, smaller package.
What is a Battery Energy Storage System (BESS)?
A BESS stores grid or solar energy in large lithium battery banks and releases it during outages or peak-demand hours, replacing diesel generators. Su-vastika builds single- and three-phase BESS from 4 KVA to 100 KVA and has installed systems as large as 200 KVA, with a roadmap to 1 MW.
Where is Su-vastika located and where are the products made?
Su-vastika designs and manufactures its products in-house at Ghamroj, near Sohna Toll Plaza, Gurugram, Haryana 122102, India. The same site houses the factory and the R&D lab.
Does Su-vastika export, and to which countries?
Yes. Su-vastika serves India and exports to 30+ countries across Asia, Africa, and the Middle East, including the UAE, Nigeria, South Africa, Kenya, Bangladesh, Nepal, and Sri Lanka.
How long do Su-vastika LiFePO4 batteries last?
Su-vastika LiFePO4 battery banks are rated for around 6000 charge cycles with an intelligent Battery Management System (BMS) for safety and long life — many times the lifespan of conventional lead-acid batteries.
