Battery storage. Silent backup, no diesel.
LiFePO₄ battery systems that store your solar for the evening, back up your home through outages and, for businesses, shave peak demand. Add one to a new solar system or retrofit an existing one.
- LiFePO₄ only
- 5–20 kWh homes
- 30–100 kWh commercial
- Silent, no fumes
*Energy charges reduced to zero where rooftop space allows a system sized to full consumption; KSEB fixed charges continue to apply.

Backup = battery kWh × 90% usable ÷ load. Real runtime varies with appliance duty cycles, inverter losses and starting current; solar recharging during the day extends it.
Built around how you use power
Homes that can't afford downtime
Work-from-home, medical equipment, or simply tired of inverter hum and diesel.
Solar owners wanting evening power
Retrofit storage to use more of what you generate.
Businesses with peak charges
Commercial systems discharge at peak to cut demand charges and ride through outages.
Choosing the right battery
| LiFePO₄ | NMC | Lead-acid | |
|---|---|---|---|
| Offered by SOLAR CONNECT | Yes: recommended | No | No |
| Thermal stability | Very good | More sensitive | Stable, but vents gas |
| Usable depth of discharge | ~90% | ~80–90% | ~50% |
| Cycle life | Highest | Medium | Lowest |
| Maintenance | None | None | Regular top-ups (flooded) |
| Weight for the same energy | Light | Lightest | Heavy |
General characteristics: exact cycle life and warranty depend on the product and are stated in your quotation.
Home batteries
Backup hours assume an essentials load of about 0.4 kW (lights, fans, fridge, router).
| Size | Usable energy | Essentials backup | Backup with 1.5 kW AC added | Indicative price |
|---|---|---|---|---|
| 5 kWh | 4.5 kWh | ~11 h | ~2.4 h | ₹2.05 L |
| 10 kWh | 9.0 kWh | ~23 h | ~4.7 h | ₹4.1 L |
| 15 kWh | 13.5 kWh | ~34 h | ~7.1 h | ₹6.15 L |
| 20 kWh | 18.0 kWh | ~45 h | ~9.5 h | ₹8.2 L |
Commercial batteries
For peak shaving and backup. No subsidy applies. Commercial projects are executed by SURYOVA.
| Size | Usable energy | Backup at 10 kW load | Indicative CAPEX |
|---|---|---|---|
| 30 kWh | 27 kWh | ~2.7 h | ₹9 L |
| 50 kWh | 45 kWh | ~4.5 h | ₹15 L |
| 75 kWh | 68 kWh | ~6.8 h | ₹22.5 L |
| 100 kWh | 90 kWh | ~9.0 h | ₹30 L |

Battery storage (BESS): common questions
How is BESS different from a normal inverter battery?
A BESS is sized in kWh, uses LiFePO₄ cells with a battery management system and works with a hybrid or battery inverter to integrate with solar. A conventional inverter battery is lead-acid, much smaller and used only for backup.
Is battery storage eligible for a subsidy?
Not under the central rooftop subsidy. State or other incentives are shown only after we verify them.
Can a battery run my air conditioner?
Yes, if the battery and inverter are sized for it. An AC draws about 1.5 kW running, so it shortens backup time considerably. The duration tool shows the effect.
Who executes commercial battery projects?
Commercial and industrial BESS projects are executed by SURYOVA ENERGYGRID 24BY7 PVT. LTD., and the contracting entity is stated in the quotation before you order.
