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.
