“I wanted to support the production of clean energy and save money.”
Fox ESS is the battery you'll see on more British roofs than any other, and that scale brings real advantages: mature firmware, a huge installed base of data, and parts and support that are never hard to find.
The EP-series packs use LiFePO₄ cells rated for 6,000+ cycles at ≥95% round-trip efficiency, available from 5.76 kWh up to a stacked 20.48 kWh. Whatever your home's appetite, there's a Fox configuration that fits.
Pair it with the EVO module for whole-home backup that engages in under 4 milliseconds, and manage everything from the FoxCloud app, including smart charging on cheap overnight tariffs.
