Inverter & Battery Buying Guide
The right inverter is sized to the load you must run and how long, with a matched battery. Pure sine wave, VA rating and battery type decide reliability and appliance safety. Here's how to size it.
6 models comparedfrom ₹6,4903 budget tiers
What to consider
1
VA rating
Add up the watts you'll run, divide by ~0.7 power factor to get VA — then pick the next size up.
2
Pure sine wave
Pure sine wave is safe for TVs, fridges, computers & fans; square wave can buzz and stress electronics.
3
Battery type
Tubular for long daily backup & life; flat-plate for short outages; lithium for compact, maintenance-free power.
4
Backup time
Backup (hours) ≈ battery Ah × 12 × 0.8 ÷ load watts. Bigger Ah = longer backup.
5
Maintenance
Tubular lead-acid needs periodic water top-up; lithium and SMF are maintenance-free.

Frequently asked
Add up the wattage of everything you want to run at once, then divide by a power factor of about 0.7 to get the VA rating — and pick the next size up for headroom. For example, ~700W of load needs about a 1000VA inverter.
