A three-phase home storage system that stacks hybrid inverter and battery modules into one slim column. It runs grid-tied or off-grid and switches to backup without interruption.
Key features
- Four-leg inverter handles 100% three-phase imbalance
- Up to 1.7× DC oversizing and reduced high-temperature derating
- PV input 180–900 V, battery range 180–700 V
- Modular, stackable design that fits modern interiors
Typical applications
Three-phase homes with PV, heat pumps or EV charging.
