The Fox ESS S2000-G2 2kW Single-Phase Solar Inverter gives UK installers dependable extra headroom for compact arrays while keeping commissioning fast and predictable. It’s purpose-built for small domestic or light-commercial systems where quiet running, tidy cabling and straightforward G99 sign-off matter.
Smart Hybrid Power for UK Homes and Installers
Centred on a high-accuracy single MPPT, the S2000-G2 supports up to 3000W PV input across a wide 80–500V window with low start-up around 60V. That combination sustains generation through cloudy spells and long shoulder hours typical of British weather. The fan-free IP65 enclosure simplifies external mounting, keeps acoustics below 25dB and removes moving parts that add maintenance.
Installer-Ready Safety & Compliance
Safety and conformity are built in: anti-islanding, residual-current and insulation monitoring accelerate UK G99 commissioning, while certification to EN62109 underpins electrical and thermal safety for long service life. Integrated data logging and FoxCloud connectivity (Wi-Fi/LAN, optional 4G) make onsite verification and handover fast, cutting call-backs.
Key Installer Features
- Single MPPT with rapid tracking across 80–500V
- 2000W rated AC output; up to 3000W max PV input
- Fan-free IP65 construction for quiet, outdoor-ready mounting (<25dB)
- FoxCloud monitoring via Wi-Fi/LAN; optional 4G for remote sites
- Integrated RCM, insulation monitoring and anti-islanding for faster G99 sign-off
- Compact form factor to reduce wall-space and handling time
If you’re wondering how the S2000-G2 behaves with short or single-aspect strings, its precise MPPT tracking and low start-up voltage help maintain yield when irradiance is uneven—supporting predictable output on typical UK roof layouts.
Specification data verified from Fox ESS S(G2) documentation (V3.4, April 2025).
Smart Monitoring & Installer-Grade Connectivity
The Fox ESS S2000-G2 gives installers and system owners complete visibility through FoxCloud. Built-in Wi-Fi and LAN allow immediate access for setup and long-term monitoring, while an optional 4 G module supports remote or off-grid sites. Local data logging simplifies performance verification during commissioning, and integrated RS485 and CAN ports provide flexible links for export limitation or BMS control.
Seamless Integration with Solar Panels & Battery Systems
The S2000-G2 integrates effortlessly with solar panels from all major manufacturers, offering stable performance for small- to mid-sized arrays. Its hybrid-ready platform supports future connection with Fox high-voltage LFP batteries when combined with compatible controllers. This makes it an ideal step-up model for installers planning scalable domestic PV systems across the UK.
Compact Design & Rugged Construction
Measuring 290×220×116mm and weighing only 5.4kg, the S2000-G2 provides outstanding installation flexibility. The fan-less IP65 housing keeps operation below 25dB, eliminating moving parts and reducing maintenance over the inverter’s lifetime. Its slim, compact profile supports fast mounting on internal or external walls, saving installers valuable time on-site.
Installer Guidance & System Notes
String design & MPPT layout
Stay within the 80–500V DC range and limit string current to 12.5A. A single well-balanced string is typically optimal for this unit, ensuring high efficiency under mixed light conditions.
Battery configuration & sizing
For hybrid-ready designs, start with 5–10kWh of Fox LFP storage and scale up using modular stack options as energy demand grows. No inverter change is required when upgrading within the Fox ecosystem.
Grid compliance & safety
Fully certified for UK G99 connection and EN62109 safety. Built-in anti-islanding, RCM and insulation monitoring simplify sign-off and guarantee safe long-term operation.
