Three - Module 12kW 15kWh All In One Energy Storage System with Dual MPPT
This 12kW 15kWh all in one energy storage system combines a pure sine wave inverter, three stackable battery modules, dual MPPT solar charging, dual AC output and WiFi monitoring in one coordinated platform.
Three 5.12kWh LiFePO4 battery modules provide 15.36kWh of rated storage and approximately 13.8kWh of usable energy at 90% depth of discharge. The configuration is suitable for customers who need higher inverter output without installing an oversized battery bank.
It can be applied in villas, larger homes, home offices, small shops and solar backup projects where several compatible loads may operate at the same time.
The built-in solar charger supports up to 9kW of photovoltaic input with one MPPT configuration and up to 15kW when both MPPT channels are used. The two tracking channels can support suitable solar strings installed on separate roof sections.
During daytime operation, solar energy can supply compatible loads and charge the battery. Stored energy can then support selected circuits when photovoltaic production decreases or utility power is unavailable.
Lighting, refrigerators, routers, security devices and home-office equipment can be assigned to the priority output. Air conditioners, pumps and other motor-driven equipment must be checked for both continuous power and startup demand.

| PV Operating Range | 90–485Vdc / 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 Location |
| Module Dimensions and Weight | Inverter: 540 × 480 × 180mm / 27kg; Battery: 540 × 480 × 164mm / 45kg Each |
The battery stack uses three 5.12kWh modules, providing 15.36kWh of rated energy and approximately 13.8kWh of usable storage at 90% depth of discharge.
This configuration is suitable when higher simultaneous output is required but the customer does not need the longer backup duration of a 30kWh or 60kWh battery bank.
Yes. The dual MPPT charger can support separate photovoltaic strings when each input follows the specified voltage, current and power limits.
Suitability depends on the running power and compressor startup demand of each unit, as well as the other loads operating at the same time.
The IP20 equipment should be installed in a dry indoor technical area with stable support, ventilation, cable access and adequate maintenance clearance.
This 12kW 15kWh all in one energy storage system is suitable for solar distributors, installers and project developers requiring high output power with a moderate modular battery reserve.
