Fox ESS PowerQ PQ1-8.0 8kW Single-Phase Hybrid Inverter
The Fox ESS PowerQ PQ1-8.0 is an 8kW single-phase hybrid inverter module for the PowerQ stackable all-in-one energy storage system. Designed to sit directly above compatible Fox ESS EQ5000-S batteries, it combines solar conversion, battery control, backup capability and connected monitoring in a compact floor-mounted package.
With 4 independent MPPT trackers, up to 20kW maximum PV input power and a battery stack scalable from 9.84kWh to 29.52kWh, the PQ1-8.0 is designed for flexible residential solar and storage projects.
Important: This listing is for the PowerQ inverter module. A compatible stack of 2-6 Fox ESS EQ5000-S 4.92kWh Slave batteries is required to form a complete system.
Battery controller distinction: The PowerQ inverter manages the battery stack directly. Do not add an EQ5000-M Master battery; PowerQ systems use EQ5000-S Slave modules only.

PowerQ Battery Sizing
Every PowerQ system uses 2-6 EQ5000-S battery modules. Each module provides 4.92kWh nominal capacity and 90% Depth of Discharge.
| EQ5000-S Batteries | Nominal Capacity | Approx. Usable Capacity at 90% DoD |
|---|---|---|
| 2 modules | 9.84kWh | 8.86kWh |
| 3 modules | 14.76kWh | 13.28kWh |
| 4 modules | 19.68kWh | 17.71kWh |
| 5 modules | 24.60kWh | 22.14kWh |
| 6 modules | 29.52kWh | 26.57kWh |
Usable-capacity figures are simple calculations based on the stated 90% Depth of Discharge and are shown for comparison. Actual available energy varies with operating conditions, system settings and conversion losses.

WiFi Monitoring:
For monitoring you can add a ShineWiFi. Please note, the Growatt Installer Code Policy is being introduced in the UK and Ireland. It means all installers will need to register an ‘Installer Code’ for using the Growatt monitoring platform. This installer code can be provided to the end user by the installer to allow for the viewing of your devices from your installer-level monitoring account. For more information, please refer to the following document: Growatt Installer Code policy
Note to end users:
Can end-users purchase this product to save money on the cost of a replacement inverter? Yes, of course! Simply purchase the inverter and arrange for a local qualified electrician to install the unit for you (should be a 1-2 hour call-out). By sourcing the inverter yourself, you can make a huge saving on the prices quoted by installation companies for supply and fit services.
