Fox ESS KH7 7kW Inverter: The High-Power Single-Phase Hybrid Solar Inverter

The Fox ESS KH7 is a powerful 7kW single-phase hybrid solar inverter designed for UK homes with significant energy demands. As part of the advanced K-Series, it expertly manages energy flow between large solar panel arrays, compatible high-voltage batteries, and the grid. Choose the KH7 for exceptional performance, maximum solar utilisation, and reliable backup power capabilities.

Unrivalled Flexibility with Triple MPPT

How to choose the best solar inverter for complex single-phase installations? The KH7 stands out with its three independent Maximum Power Point Trackers (MPPTs), a feature confirmed in the K-Series datasheet. This provides outstanding flexibility for optimising energy harvest from large solar panel systems spread across multiple roof orientations or those affected by varying shade conditions, ensuring maximum yield from your entire setup.

High-Capacity Battery Storage Ready

This hybrid inverter is built for serious battery energy storage. It integrates seamlessly with compatible high-voltage LFP batteries (85-480V range) and boasts a high maximum charge/discharge current of 50A, according to the technical documentation. This allows for efficient management of large battery banks, enabling you to store substantial amounts of surplus solar energy for use whenever needed.

Optimise Savings with High Efficiency & Smart Control

Minimise energy costs and maximise your solar investment. The KH7 operates at impressive efficiency levels (up to 97.80% Max. Efficiency reported in the specifications). By intelligently managing stored energy, it significantly reduces reliance on grid electricity, especially during peak price periods. Its smart features also allow for potential optimisation using time-of-use tariffs, enabling battery charging from the grid during cheaper off-peak times.

Robust Single-Phase Backup Power (EPS)

Maintain power for essential circuits during outages. When paired with a compatible battery bank, the KH7 provides a strong 7kVA single-phase Emergency Power Supply (EPS) output. The datasheet confirms a rapid switchover time (<20ms), ensuring near-seamless backup power to keep critical appliances running during grid failures.

Durable Design & Remote Monitoring

Engineered for reliability, the KH7 inverter features an IP65 rating, making it suitable for outdoor installation (ensure use of appropriate solar cabling and solar mounting systems). Monitor your system's performance, energy flows, and battery status remotely via the Fox ESS Cloud platform, accessible with optional WiFi, 4G, or LAN communication modules.
