Fox ESS F5000 – efficient 5kW inverter for UK homes and small businesses
The Fox ESS F5000 5kW Single Phase String Inverter is a robust, high-efficiency choice for British properties seeking reliable energy yield with smart control. Engineered within the Fox ESS F Series (G2) family, it offers the performance step-up many homes and SMEs want when moving beyond 3.6–4.6kW systems, without jumping to three-phase hardware. With maximum efficiency up to 97.4% and Euro efficiency of 96.8%, it converts more of your PV generation into usable AC power, supporting lower bills and improved ROI.
Sitting between the F3600 and F6000 models, the F5000 suits typical 5kW arrays and retrofit upgrades where additional module capacity has been added over time. Its transformerless design and compact form factor streamline installation, while IP65 weather protection ensures dependable outdoor operation in British conditions. Weighing just 15.5kg and measuring 402×453×148mm, it’s installer-friendly and neat on the wall, inside or out. Noise stays below 30dB thanks to natural convection cooling, maintaining a low profile in homes and customer-facing spaces.
Smart monitoring and reliable single-phase performance
The F5000’s dual independent MPPTs and wide operating voltage window (80–550V) give installers flexibility to configure strings across mixed orientations or partial shading, preserving yield throughout the day. A low 120V start-up helps the system begin generating earlier in marginal light, useful in the UK shoulder seasons and on east/north-east aspects. Rated output current is 21.7A with up to 5,500VA max apparent power, providing healthy headroom under strong irradiance.
Monitoring and safety are comprehensive. Built-in Wi-Fi/LAN (with optional 4G) connects to the FoxCloud app and portal for real-time yield, status, and alerts. Protection features include insulation and residual-current monitoring, DC reverse-polarity, anti-islanding, and AC over-voltage/over-current safeguards. Surge protection and DC switch options support best-practice site design and maintenance. Compliance with EN/IEC 62109-1/2 and EN 61000 series EMC standards underpins grid-safe operation for UK installers.
Integration & system compatibility
The Fox ESS F5000 integrates cleanly with today’s high-output monocrystalline and N-Type TOPCon modules, including ranges from Aiko and Jinko, making it suitable for efficient, space-constrained rooftops. Dual MPPT inputs maintain performance across split strings, ideal for homes with complex roofs or dormers. For racking, pair with quality mounting systems to ensure fast installation and long-term stability on tiled, slate, or metal roofs.
Planning for storage? The F Series (G2) is battery-ready when used with a Fox ESS charge controller, enabling future addition of compatible Fox storage for self-consumption gains or export management. Communications (RS485, meter/CT) facilitate integration with monitoring, smart meters, and load-management devices, useful if you’re coordinating PV with EV charging, heat pumps or other electrification loads as your system evolves.
