12kW 15kWh All In One Stackable Energy Storage System Three Module

Three - Module 12kW 15kWh All In One Energy Storage System with Dual MPPT

High - Power All In One ESS with a Compact Battery Stack

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.

Why Choose the 12kW and 15kWh Configuration

Dual MPPT Solar Charging and Load Planning

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.

Engineering and Installation Specifications

12kW 15kWh All In One ESS FAQ

How many battery modules are included in the 15kWh configuration?

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.

Why combine a 12kW inverter with a 15kWh battery?

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.

Can the system connect to two separate solar strings?

Yes. The dual MPPT charger can support separate photovoltaic strings when each input follows the specified voltage, current and power limits.

Is this configuration suitable for several air conditioners?

Suitability depends on the running power and compressor startup demand of each unit, as well as the other loads operating at the same time.

Where should the stackable system be installed?

The IP20 equipment should be installed in a dry indoor technical area with stable support, ventilation, cable access and adequate maintenance clearance.

Compact High-Power ESS Project Support
