Fox ESS S1000-G2 1.0kW Inverter: Compact, Efficient Single-Phase Solar Inverter for UK Homes

The Fox ESS S1000-G2 is a reliable 1.0kW single-phase inverter purpose-built for smaller UK domestic solar systems. As part of the trusted S-G2 series, it offers high conversion efficiency, robust build quality, and smart monitoring features all within a compact, user-friendly package.

Perfect Fit for Small-Scale Installations

For smaller solar systems with limited panel numbers or roof space, the S1000-G2 offers a practical solution. With a rated output of 1,000W (1.0kW) and maximum input power of 1,500W, it’s ideally suited for compact solar arrays typically seen in UK terraced or urban homes.

Efficient Energy Conversion, Low Start-Up

According to the datasheet, the S1000-G2 delivers excellent performance with a maximum efficiency of up to 97.4%. It also starts producing electricity earlier in the day thanks to its ultra-low 60V start-up voltage helping to make the most of British daylight hours and increasing your solar yield.

Durable IP65 Weatherproof Build

With an IP65 rating, the S1000-G2 is suitable for both indoor and outdoor installation, giving installers greater flexibility. Its passive cooling design means no internal fans, reducing both operational noise and maintenance requirements.

Wi-Fi Enabled Smart Monitoring

Keep track of your solar generation from anywhere. The S1000-G2 supports real-time monitoring via the Fox ESS Cloud platform, accessible through a smartphone app or desktop browser. This helps you stay in control of your system’s performance and troubleshoot remotely if needed.

Simple Setup with Compact Dimensions

Measuring just 29 x 22 x 11.6cm and weighing 5.4kg, the inverter is exceptionally easy to handle and install, even in confined areas. A clear LCD interface provides basic system information locally.
