Fox ESS F3600 3.6kW Single Phase String Inverter

Fox ESS F3600 – efficient 3.6 kW inverter for UK solar homes

The Fox ESS F3600 3.6 kW Single Phase String Inverter delivers high-performance power conversion for modern British solar systems. Designed by Fox ESS – a global innovator in energy storage and inverter technology – this model provides the perfect balance of reliability, efficiency, and intelligent monitoring for residential and small commercial use. Its robust IP65-rated enclosure ensures long-term durability even in challenging outdoor environments, making it ideal for UK installations exposed to variable weather conditions.

Part of the advanced Fox ESS F Series (G2) range, the F3600 sits between the smaller F3000 and larger F5000 models, offering the sweet spot for homes with typical 10–14 solar panel arrays. It achieves up to 97.4 % maximum efficiency and includes dual MPPT tracking to optimise yield across multiple roof orientations. Whether paired with high-output panels or compact systems, this inverter delivers consistent performance and long-term value for both new installs and system upgrades.

Smart monitoring and reliable single-phase performance

The Fox ESS F3600 G2 features dual independent MPPT inputs and a wide operating voltage range (80 – 550 V) for flexible string configuration and maximum energy capture. It starts quickly at a low 120 V input, ensuring efficient generation even in low light conditions – a major benefit for UK roofs facing north or east. Natural convection cooling keeps noise levels below 30 dB, making it suitable for both indoor and outdoor use without disturbance.

Connectivity and control are central to the F3600’s appeal. With integrated Wi-Fi and LAN monitoring modules as standard (and optional 4G support), users can track generation in real time through the FoxCloud app or web portal. This advanced monitoring platform provides instant visibility of system output and performance metrics anywhere, anytime. Comprehensive safety features such as DC reverse-polarity, AC over-voltage and anti-islanding protection ensure safe and stable operation throughout its lifetime.

Lightweight (15.5 kg), compact, and built with premium components, the F3600 offers both ease of installation and exceptional energy conversion efficiency. As a transformerless unit with Euro efficiency of 96.8 %, it reduces waste loss and maximises power output – helping homes and businesses make the most of every kilowatt generated.
