The Fox ESS EVO is a next-generation, fully integrated all-in-one energy storage system combining the battery and inverter in a single, sleek unit. Designed for straightforward installation and advanced monitoring, the EVO transforms how homeowners power their heat pumps, by storing electricity during cheap windows and deploying it when they need it most.

With dynamic tariffs now widely available across the UK, the EVO can be programmed to charge during cheaper off-peak windows and intelligently deploy that stored energy when prices are higher. This means your heat pump can run almost entirely on low-cost electricity without the need for solar panels. The system supports cascading of up to three units for expanded capacity, and integrates seamlessly with any heat pump installation.
