Fox ESS PowerQ 11.4kW + 7.95kWh Battery Bundle
This CSE Solar USA bundle combines the Fox ESS PowerQ 11.4kW split-phase hybrid inverter with two EQ4000 lithium iron phosphate battery modules. The batteries stack beneath the inverter to form one floor-standing, outdoor-rated tower with 7.95 kWh of storage.
Sizing note: with 2 battery modules the PowerQ delivers 5,760 W of rated backup power (load start capacity 50 A LRA). Grid-tied output remains 11,400 W. Add EQ4000 modules if you need the full 11,400 W in backup.
Key Features
- 7.95 kWh of LFP storage from two EQ4000 modules, expandable to 5 modules (19.87 kWh) per inverter
- 11,400 W grid-tied AC output at 120/240 V split phase
- 5,760 W rated backup output with 2 battery modules (rises to 11,400 W with 4 or 5 modules)
- Up to 22,800 W of PV on 3 MPP trackers, 600 Vdc
- Type 4X inverter and IP65 batteries for indoor or outdoor installation
