Deye 12 kW Inverter (3ph) + 15.36 kWh Battery
24/7 without days off
Industrial-grade energy security for your home. This kit is designed specifically for three-phase households with high energy consumption. The powerful 12kW inverter effortlessly powers heat pumps, electric saunas, induction cooktops, and EV chargers. Three battery units provide a massive 15.36 kWh reserve, sufficient for prolonged autonomous operation of a large house.
Key Feature: This is a Low Voltage (LV) system. Unlike many competitors, it operates with safe 48V batteries, making it safer, more affordable, and easier to scale than High Voltage (HV) systems.
Why is this kit the perfect choice?
True 3-Phase Power: The inverter provides a standard 400V output and supports 100% unbalanced loads. You can heavily load one phase (e.g., with a kettle) while others remain idle, and the system will remain stable (up to 50% nominal power per phase).
12kW Power: No need to compromise. Running a washing machine, oven, air conditioners, and a well pump simultaneously is standard operation for this beast.
Massive Energy Reserve: Three batteries with a total capacity of 15.36 kWh allow you to survive over 24 hours of blackout in eco-mode or an entire evening of heavy usage.
Scalability: Supports a large solar array and allows for easy addition of more battery modules in the future.
