FoxESS H3-Pro-25.0 Hybrid Inverter 25 kW Three-phase High Voltage 3 MPPT
The FoxESS H3-Pro-25.0 is a three-phase hybrid inverter rated 25 kW from the H3 Pro series, sized for large residential and small commercial plants with high-voltage storage. It runs 3 MPP trackers with two strings each, up to 60 kWp of PV array.
There are two battery inputs with CAN communication, so two towers can be paralleled to reach substantial storage sizes. The backup output delivers about 30 kVA continuous with a 36 kVA peak for sixty seconds, useful when motors or pumps start while off-grid.
MPPT efficiency is 99.9%, battery-to-grid 97.1% and PV-to-battery 98.1%. The enclosure is IP65, cooling uses smart fans below 55 dB and the operating range spans -25 to +60 °C. Interfaces include meter, Wi-Fi, DRM, USB, BMS over CAN, RS485, Ethernet and an SG-ready contact for the heat pump.
