Single Phase Solar Inverter

The Fox ESS H1-5.0-E-G2 5 kW Hybrid Solar Inverter is a high-efficiency, single-phase solution for UK homes and light-commercial sites that need more headroom than the 3.7 kW model while retaining the same installer-friendly G2 platform. With dual MPPT inputs, wide 80–550 V operating window and peak efficiency around 97.08 %, it delivers stable yield on multi-aspect arrays and challenging British irradiance.

Engineered for durability and compliance, the H1-5.0-E-G2 features IP65 weather protection, natural cooling (<15 dB), integrated residual-current and insulation monitoring, anti-islanding and surge protection. Smart connectivity via FoxCloud (Wi-Fi/LAN, optional 4G) enables remote commissioning, diagnostics and live performance data. It’s an ideal solar inverter UK choice for upgrading systems or specifying new builds that require a single-phase inverter with future-proof battery integration.

Compatible with Fox high-voltage LFP storage, this MPPT solar inverter is a high-efficiency photovoltaic inverter suitable for homeowners and professionals seeking an expandable inverter with battery integration. Certified to G99 and EN 62109 standards.

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.

Fox ESS S1500-G2 1.5kW Single-Phase Solar Inverter steps up power for small UK arrays that need a little more headroom.
