Fox ESS G7 7kW Single Phase Solar Inverter (Triple MPPT)

High-performance 7kW single-phase inverter for UK solar systems

The Fox ESS G7 7kW Single Phase Solar Inverter represents the next step in smart energy conversion for domestic and small business installations across the UK. Part of the renowned Fox ESS G Series, the G7 is engineered for those seeking a reliable, efficient, and future-ready inverter solution that maximises solar generation while keeping operating costs low.

With its triple Maximum Power Point Tracking (MPPT) design, the G7 offers superb flexibility for systems installed across multiple roof angles or orientations. This ensures that each solar string performs at its optimal power output - a vital advantage for varied or shaded rooftops common in British properties. Supporting a maximum input power of 10,500W and a wide voltage range from 80V to 550V, it delivers robust performance under all weather conditions.

Advanced efficiency and protection technology

Built on Fox ESS’s commitment to innovation and reliability, the G7 achieves a maximum efficiency of 97.8% and an impressive European weighted efficiency of 97.4%. Its 99% MPPT tracking accuracy ensures near-perfect conversion of DC energy from solar panels into usable AC power for homes and small commercial sites. Combined with low start-up voltage and rapid power tracking, it maximises generation from the first light of day to dusk.

The G7 also includes a full suite of integrated protection features for safe and dependable operation. Users benefit from anti-islanding protection, residual current monitoring, AC short-circuit protection, surge protection, and reverse polarity safeguards. The IP65-rated enclosure guarantees durability against British rain and dust exposure, making it ideal for both indoor and outdoor installation.

Effortless monitoring and control

Fox ESS integrates advanced connectivity for real-time performance tracking. Through the FoxCloud web portal or smartphone app, system owners can monitor key metrics such as daily yield, inverter status, and power flow - anytime, anywhere. The system supports RS485, Meter/CT, and DRM communication interfaces, with optional Wi-Fi or 4G modules for added flexibility. This ensures seamless data access for installers and users alike, supporting informed energy management decisions.

System integration and compatibility

The Fox ESS G7 7kW Single Phase Solar Inverter integrates seamlessly with a wide range of solar panels and battery storage systems, offering system designers the flexibility to create efficient and scalable installations. Its intelligent power management enables easy expansion, whether paired with new panels or upgraded with a compatible battery for hybrid operation in the future.

Thanks to its triple MPPT input configuration, the G7 optimises energy yield across multiple strings, supporting installations with mixed panel orientations or partial shading. This flexibility makes it a smart choice for UK homeowners and businesses aiming to maximise performance across complex roof structures.
