Performance

Fox ESS · the UK's #1 battery brand

Performance is the package most of our customers choose, and for good reason. It pairs the same premium LONGi 530W panels with Fox ESS, the UK's number-one home battery brand, trusted on tens of thousands of British roofs.

Choose the 5.76 kWh EP6 to cover the evening, or the 11.52 kWh EP12 to run most of your home overnight. Both use LiFePO₄ cells rated for 6,000+ cycles and deliver ≥95% round-trip efficiency, so very little of the energy you store goes to waste.

Add Fox's EVO module and the system becomes a whole-home backup that kicks in within milliseconds of a power cut. The FoxCloud app puts every kilowatt in your pocket, and the whole package is heat-pump ready for whatever you electrify next.
