12kW 15kWh Residential Energy Storage System for Villas with Dual MPPT
This 12kW 15kWh residential energy storage system is designed for villas, larger homes and residential properties that require higher output power with a moderate battery reserve.
Three 5.12kWh LiFePO4 battery modules provide 15.36kWh of rated energy and approximately 13.8kWh of usable storage at 90% depth of discharge. The 12kW pure sine wave inverter provides additional output capacity for homes with several compatible circuits operating at the same time.
This configuration is suitable for customers who need stronger load support but do not require the longer operating duration of a 30kWh or 60kWh home battery system.
The system supports up to 9kW of photovoltaic input with one MPPT and up to 15kW when both MPPT channels are used. Separate tracking channels can be useful for solar panels installed on two suitable roof sections.
For residential backup, lighting, refrigerators, routers, security equipment and home-office devices can be placed on the priority output. Selected sockets and other flexible loads can be managed separately to preserve battery energy.
The 24kVA surge rating provides short-duration headroom for compatible motor-driven equipment. Air conditioners, water pumps and compressors must still be checked for running power, startup current and simultaneous operation.
| Residential AC Connection | 220 / 230 / 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 |
| MPPT Operating Window | 90–485Vdc |
| Maximum PV Open-Circuit Voltage | 500Vdc |
| Charging Current Limits | 160A PV / 160A AC / 160A Combined |
| Battery Operating Voltage | 51.2Vdc Nominal / 40.5–54.5Vdc Range |
| Installation Environment | IP20 / -10°C to 50°C / Dry Indoor Technical Area |
It can support selected essential circuits overnight when average consumption is controlled. Actual duration depends on active loads, efficiency and battery reserve settings.
It is suitable for properties with higher simultaneous demand than smaller residential systems. A complete load assessment is required before final selection.
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 with dual MPPT. Final string design must follow the voltage and current limits.
Solar charging and compatible generator charging can be used according to the selected settings and available source capacity.
This 12kW 15kWh residential energy storage system is suitable for solar installers, distributors and project developers serving villas, larger homes and high-output residential backup projects.
