Who needs a battery?
Most Indore homes don't — net metering makes on-grid solar the best value. A battery makes sense when outages are frequent or long, or when equipment must not stop (clinics, home offices, cold storage).
Sizing backup the smart way
| Backup need | Typical load | Battery (usable) |
|---|---|---|
| Lights, fans, Wi-Fi for 4 h | ~400 W | ~2 kWh |
| Plus refrigerator and TV | ~700 W | ~3–4 kWh |
| Home office with 2 laptops, printer | ~900 W | ~4–5 kWh |
We wire only these circuits to the backup board, which keeps the battery small and affordable.
