Inverter, Charger & UPS in One Powerful Unit

This advanced unit features:

• Pure Sine Wave Inverter – Delivers 230V output, up to 4000 W continuous (9000 W peak)
• High-Capacity Battery Charger – 220 A charging current with adaptive charging for all battery types, including LiFePO₄
• Integrated UPS Mode – Seamlessly switches to battery during grid failure without interruption

The built-in PowerAssist feature prevents overload by balancing grid/generator power with battery output, while PowerControl lets you limit grid current to avoid tripping.
