12kW 30kWh Residential Energy Storage System for Villas and Extended Backup
This 12kW 30kWh residential energy storage system is designed for villas, larger homes, remote residences and residential properties requiring higher output power with a larger household energy reserve.
Six 5.12kWh LiFePO4 battery modules provide 30.72kWh of rated storage and approximately 27.6kWh of usable energy at 90% depth of discharge. The capacity can support evening solar self-consumption and selected household circuits during longer utility interruptions.
The system is intended for homes where refrigeration, lighting, internet equipment, security systems, gates, home-office devices and selected higher-power appliances need coordinated solar and battery support.
Daytime Household Supply
Solar generation can support compatible home loads while additional photovoltaic energy charges the battery.
Evening Solar Self-Consumption
Stored solar energy can supply selected circuits after rooftop photovoltaic production decreases.
Essential Circuit Backup
Priority household circuits can remain active while flexible or higher-consumption appliances are managed separately.
Extended Outage Recovery
Compatible utility input or a generator can provide additional battery charging during poor weather or prolonged utility outages.
Dual AC outputs help installers separate essential circuits from flexible household loads. Refrigeration, lighting, routers, security systems, gates and selected home-office equipment can be assigned to the priority output.
The 24kVA surge rating provides short-duration starting headroom for compatible air conditioners, pumps and compressors. Continuous combined output remains limited to 12kW, so simultaneous load demand must be checked before installation.
The solar charger supports up to 9kW with one MPPT or up to 15kW when both MPPT channels are used. Two tracking channels can support suitable photovoltaic strings installed on different roof sections or orientations.
Approximately 27.6kWh of usable energy does not represent a fixed number of backup hours. Actual duration depends on active loads, inverter efficiency, battery reserve settings, temperature and available solar charging.
| Residential AC Output | 12kW / 220, 230 or 240Vac / L + N + PE |
| Utility Input Range | 90–280Vac Normal Mode / 170–280Vac UPS Mode |
| Frequency and Power Factor | 50Hz / 60Hz Auto Detection / PF 1.0 |
| Backup Transfer Response | 10ms APP / UPS Mode; 20ms Generator Mode |
| Rooftop PV Limits | 90–485Vdc MPPT Range / 500Vdc Maximum Open-Circuit Voltage |
| Charging Current Limits | 160A PV / 160A AC / 160A Combined |
| Battery Voltage Platform | 51.2Vdc Nominal / 40.5–54.5Vdc Operating Range |
| Installation Environment | IP20 / -10°C to 50°C / Dry Indoor Technical Area |
| Home Battery Arrangement | Six Stackable Modules / Approximately 45kg per Module |
This residential energy storage system supports solar self-consumption, compatible utility charging and backup operation. This page does not claim electricity selling or power export to the grid.
It can support a planned group of essential household circuits overnight. Actual duration depends on average consumption, battery settings and available solar charging.
Typical priority circuits include refrigeration, lighting, routers, security equipment, gates, communication devices and selected home-office loads.
Compatible equipment may be supported when its running power, startup current and combined demand remain within the inverter limits.
The system supports up to 9kW with one MPPT or up to 15kW using both MPPT channels, subject to the specified electrical limits.
Compatible utility input or a properly sized generator can supplement solar charging when photovoltaic production is insufficient.
This 12kW 30kWh residential energy storage system is suitable for solar installers, distributors and project developers serving villas, larger homes and extended residential backup applications.
