12kW 25kWh Residential Energy Storage System for Villas and Home Backup

Villa Solar Battery with Extended Household Backup

This 12kW 25kWh residential energy storage system is designed for villas, larger homes and residential properties requiring higher output power together with an extended household battery reserve.

Five 5.12kWh LiFePO4 modules provide 25.6kWh of rated storage and approximately 23.04kWh of usable energy at 90% depth of discharge. The capacity can support evening solar self-consumption and selected household circuits during utility interruptions.

The configuration sits between the 20kWh and 30kWh options, making it suitable for homeowners who require additional backup time without installing a larger battery bank.

Residential Energy Use from Daytime to Outage Backup

Household Load and Rooftop Solar Planning

Dual AC outputs help installers separate essential circuits from flexible household loads. This allows stored energy to be reserved for equipment that must remain active during an outage.

The 24kVA surge rating provides short-duration starting headroom for compatible air conditioners, pumps and compressors. Continuous combined output remains limited to 12kW.

The dual MPPT charger supports up to 15kW of photovoltaic input. Two channels can be used for suitable solar strings installed on different roof orientations, provided all voltage and current limits are followed.

Residential Electrical and Installation Data

12kW 25kWh Residential Energy Storage FAQ

Is 25kWh suitable for overnight villa backup?

It can support a controlled group of essential circuits overnight. Actual duration depends on average household consumption, system efficiency and battery settings.

Which circuits should be prioritized?

Common priority circuits include refrigeration, lighting, routers, security equipment, gates and selected home-office devices.

Can it support air conditioners and water pumps?

Compatible equipment may be supported when its running power and startup demand remain within the inverter and surge limits.

How much rooftop solar can be connected?

The system supports up to 15kW using dual MPPT, subject to the specified voltage, current and photovoltaic string-design limits.

Can the battery recharge during several cloudy days?

Compatible utility or generator charging can supplement solar energy when photovoltaic production is insufficient.
