The H3 Pro is a three-phase hybrid inverter and AC charger, available in 15–30kW models and designed for high-demand sites. It combines robust three-phase power with advanced control features, while supporting scalable storage when paired with compatible Fox ESS high-voltage batteries.
The inverter can be installed with EP Series or EQ/CQ Series batteries, or without batteries as a grid-tied, battery-ready inverter. With 2 battery inputs, battery capacity can be scaled to over 168kWh per inverter (with CQ7), with further scaling possible by installing inverters in parallel and adding batteries to each inverter.
