Power cuts on an on-grid system: a battery add-on that fixes them
On-grid inverters switch off within 200 milliseconds when KSEB fails. A hybrid MPPT charger added to a 3 kW system now runs the house from a battery during cuts.

Export to KSEB by day. Keep the lights on through power cuts.
A hybrid system exports to the grid like on-grid, but keeps a battery for essential loads during outages. You choose which circuits stay alive: lights, fans, the fridge, the Wi-Fi router. When the grid fails, the hybrid inverter switches them to the battery on its own.

- 2,500+ installations
- MNRE-approved
- Since 2009
Advantages
- Exports surplus power to KSEB under net metering, like on-grid
- Battery backup for essential loads during power cuts
- Automatic changeover when the grid fails
- Battery sized for the loads that matter, usually 2 to 5 kWh for a Kerala home
Honest trade-offs
- Costs more than on-grid: a battery plus a hybrid inverter premium
- Batteries need replacing during the life of the system

“Our first plant was on-grid, and when KSEB's power went we could not use it. That is why we decided on hybrid. It has been three years, and it averages above 20 units a day.”

Hybrid solar and KSEB's new rules
A hybrid system powers the house first, charges the battery, exports the surplus and keeps the subsidy, running with or without KSEB supply.
