Overview
The FoxESS All-in-One range puts the inverter and battery in one integrated, plug-and-play unit. The PowerQ Stackable AIO pairs a 3.7–11 kW PQ hybrid (or AC-coupled) inverter with stackable EQ battery modules, IP66-rated for outdoor whole-home solar-and-storage. The Mini Qube is a compact 0.8 kW micro system using 2.6 kWh LFP modules (expandable to four) for smaller homes and top-up storage. A third model, the EViO AIO, is also part of the FoxESS line-up. We list the range as one product for launch and will add individual model pages as the UK line is finalised.
