FOX ESS

The Fox ESS KH7 is a 7 kW single-phase hybrid inverter designed to deliver high-efficiency solar energy conversion with seamless battery integration for modern UK homes. Featuring dual MPPT inputs, it optimises yield across varied roof orientations and low-light conditions, making it an excellent choice for both new and retrofit photovoltaic systems.

Engineered for longevity, the KH7 offers IP65 protection for outdoor installation, passive cooling for near-silent operation, and robust grid safety compliance under G99 and EN 62109 standards. It supports high-voltage LFP batteries, enabling efficient energy storage and backup capability. With real-time monitoring through FoxCloud, users and installers can track performance, analyse yield, and manage updates remotely via Wi-Fi or LAN connectivity.

Delivering up to 97.8 % efficiency and 99.9 % MPPT accuracy, the KH7 balances performance, safety, and reliability—ideal for British homes aiming to maximise solar self-consumption.

The Fox ESS KH9 is a 9 kW single-phase hybrid inverter built for larger UK homes and light-commercial arrays that need higher PV and storage headroom. Its quad MPPT design optimises generation across complex roof layouts, with an 80–500 V tracking window and 75 V start-up to maintain output in low-light British conditions. Peak conversion efficiency reaches 97.8 % with Euro 97.4 %, helping to turn more irradiance into usable power throughout the year.

Engineered for longevity and ease of commissioning, the KH9 features a robust IP65 enclosure for outdoor mounting, fan-free natural cooling for near-silent operation, and full UK grid compliance (G99) with safety certified to EN 62109. It pairs natively with Fox high-voltage LFP batteries (85–480 V), enabling efficient charging, export control and EPS backup (with batteries). Live performance and remote diagnostics are available via FoxCloud using built-in Wi-Fi/LAN, with optional 4G for remote sites.

If you’re upgrading from mid-range inverters, the KH9’s higher PV input capacity and four independent MPPTs make it an excellent match for multi-aspect arrays and future battery expansion.
