Fox ESS PowerQ 11.4kW Hybrid Inverter 30-139-1132F-00

The FOX ESS 11.4kW Hybrid Inverter w/RGM & APS (part number FXESS 30-139-1133F-00, often associated with models like H1-11.4-US or PowerQ AIO series) is a high-performance, split-phase hybrid inverter tailored for the North American residential solar + storage projects. It integrates with FOX ESS’s PowerQ All-in-One (AIO) energy storage systems, supporting high-voltage LiFePO₄ batteries like the EQ4000 modules for scalable backup power and energy management.

This inverter supports grid-tied, off-grid-capable, and hybrid applications, offering backup during outages, PV self-consumption optimization, time-of-use shifting, and generator integration (via compatible hubs like Fox Smart Hub G2).

Application scenarios and idea for:
1. This Mode can't compatible with the FOX ESS Smart hub G2, No RGM. Tigo RSD transmitter is integrated. It apply to integrate FOX ESS EQ4000 LFP Battery for storage system for TOU ( Time of use ) to electricity bill shave.
2.  PV-Only Grid-tie solar system.
