Fox ESS KH10.5 10.5kW Single-Phase Hybrid Inverter: Advanced Energy Solution for Large Residential Systems

The Fox ESS KH10.5 is a robust 10.5kW single-phase hybrid inverter, engineered to meet the energy demands of large UK homes. As part of the advanced K-Series, it efficiently manages energy flow between extensive solar panel arrays, compatible high-voltage batteries, and the grid. Choose the KH10.5 for exceptional performance, maximum solar utilisation, and reliable backup power capabilities.

Enhanced Flexibility with Quadruple MPPT

The KH10.5 stands out with its four independent Maximum Power Point Trackers (MPPTs), allowing for optimal energy harvest from large solar panel systems spread across multiple roof orientations or those affected by varying shade conditions. This ensures maximum yield from your entire setup.

High-Capacity Battery Storage Integration

This hybrid inverter is built for substantial 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. This allows for efficient management of large battery banks, enabling you to store significant amounts of surplus solar energy for use whenever needed.

Optimise Savings with High Efficiency & Smart Control

Operating at impressive efficiency levels (up to 97.8% Max. Efficiency), the KH10.5 intelligently manages stored energy, significantly reducing 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.

Reliable Single-Phase Backup Power (EPS)

Maintain power for essential circuits during outages. When paired with a compatible battery bank, the KH10.5 provides a strong 10.5kVA single-phase Emergency Power Supply (EPS) output. A rapid switchover time (<20ms) ensures near-seamless backup power to keep critical appliances running during grid failures.

Durable Design & Remote Monitoring

Engineered for reliability, the KH10.5 inverter features an IP65 rating, making it suitable for outdoor installation. 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.
