Fox ESS S2500-G2 2.5kW Inverter: The Efficient & Compact Single-Phase Solar Inverter

The Fox ESS S2500-G2 is a compact, efficient, and reliable 2.5kW single-phase string inverter, ideal for small-to-medium residential solar installations in the UK. Belonging to the S-G2 series, it efficiently converts DC power from your solar panels into usable AC electricity for your home, offering a step up in power from the smallest models while maintaining a compact form factor.

Ideal Power for Modest Solar Arrays

What size inverter do you need for a typical small domestic system? The S2500-G2's 2.5kW (2500W) rated output, coupled with a maximum recommended DC input of 3750W according to the product datasheet, makes it suitable for slightly larger small-scale solar panel setups. Its single Maximum Power Point Tracker (MPPT) is perfect for simple arrays where panels share a consistent orientation and are unaffected by significant shading.

Efficient & Reliable Performance

Get great performance from a compact unit. The S2500-G2 delivers high conversion efficiency, with the manufacturer's technical data listing a maximum efficiency of up to 97.4%. This ensures minimal energy loss, maximising the usable power from your solar generation. Its low start-up voltage (60V) also allows it to start converting energy earlier in the day, contributing to overall yield.

Compact, Lightweight & Durable

Engineered for ease of installation and longevity, this PV inverter is both lightweight (only 5.4kg as per the specs) and robust. It features an IP65 rated enclosure, offering excellent protection against dust and water, making it suitable for various installation locations, including outside (ensure correct solar cabling and solar mounting systems are utilised).

Monitoring Capabilities

Track your solar system's generation easily. The S2500-G2 includes an integrated LCD display for quick status checks. The product literature confirms support for optional WiFi or 4G modules, enabling connection to the Fox ESS Cloud platform for convenient remote monitoring via smartphone app or web portal.
