An idea to consider during uncertain geopolitical times: Indian govt gives up to Rs. 78,000 subsidy for solar panels. Some states give additional 20-30k subsidy. So, by investing a little in your own batteries and inverter, and getting the rest, like solar panels, on subsidy, you can get 3 KW of hybrid power (On-grid to avail subsidy, but also can work off-grid during power failure). Typical practical setup: > 2–3 kW solar panels (to claim maximum subsidy) > Hybrid inverter > 3–5+ kWh LiFePO4 battery bank (preferred for longer life) Can keep your home powered for days even if some loserpower adversary takes out the grid, to blame the govt, and causes a blackout. Confirm with your local electricity company whether they allow hybrid configurations in your area (rules can vary by state and I don't know for sure).
