Growatt WIT 40K-XHU Hybrid Inverter | 40000W | Three-Phase | 4 MPPT | UPS | Off-grid

The WIT XHU series from Growatt are high-power three-phase hybrid inverters designed for commercial and industrial applications requiring maximum flexibility and reliability. They incorporate multiple MPPT trackers and direct high-voltage battery input, enabling advanced energy management and efficient integration of large photovoltaic fields.

Thanks to their UPS function with a switching time of less than 10 ms and black start capability, they ensure power supply continuity in the event of grid failures. In addition, they support parallel operation in off-grid mode, 100% unbalanced three-phase output, and up to 150% overload capacity in off-grid mode, delivering stable performance even in weak grid environments (SCR<1.2).

The intelligent air cooling system prevents power derating up to 50°C ambient temperature. With IP66 protection rating, transformerless design, and monitoring via OLED + LED display and RS485/CAN/USB/WiFi/LAN communications (optional), they ensure robust and fully supervised operation. They are compatible with high-voltage batteries (200–800 V) with BMS communication via RS485/CAN.
