Fox ESS PowerQ 11.4kW Split-Phase Hybrid Inverter
PowerQ is the Fox ESS all-in-one residential energy storage platform. The 11.4kW hybrid inverter (model AIO-H1-11.4-US) is the head unit of the system: it mounts on top of a stack of Fox ESS EQ4000 lithium iron phosphate battery modules, connects your solar array, the grid and your backup loads, and manages charging, self-consumption and backup from one Type 4X enclosure.
With three independent MPP trackers, a 600 Vdc PV input and up to 22,800 W of solar, the PowerQ suits new DC-coupled solar-plus-storage systems, and it can also be AC coupled to an existing PV system. Up to four PowerQ units can be paralleled through the Fox ESS Hub G2 for larger homes.
Key Features
- 11,400 W continuous AC output at 120/240 V split phase, with surge capability to 15,390 VA for 60 seconds
- Up to 22,800 W of PV across 3 MPP trackers, 600 Vdc maximum input
- 97.0 % CEC efficiency and 97.6 % peak efficiency
