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

The Best Diesel Generator Alternative: Lithium Battery ESS by Su-vastika
A lithium Battery Energy Storage System (BESS) is the best diesel generator alternative in India — silent, pollution-free, instant backup at a far lower running cost. How it works, where it wins, and how to size one from home systems up to 500 kVA.
Solar hybrid PCU MPPT 5.5KVA technology described
How the Su-vastika 5.5 kVA Solar Hybrid PCU works: MPPT solar charging (up to 30% more than PWM), solar-first priority logic, lithium BMS integration, Bluetooth/Wi-Fi app, over-the-air updates, digital warranty and BIS certification.
MPPT Solar Charge Controller for 12V Systems: How It Works & Why It Charges Faster
On a 12V solar system the panel peaks near 17.2V but the battery only wants ~14V. An MPPT charge controller turns that voltage gap into extra charging current with a buck DC-DC stage - here is exactly how it works, and why it beats PWM.

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.
