Fox ESS S1500-G2 1.5kW Inverter: The Compact & Efficient Single-Phase Solar Inverter

The Fox ESS S1500-G2 is a compact and highly efficient 1.5kW single-phase string inverter, perfectly suited for smaller residential solar energy systems in the UK. As part of the S-G2 series, it reliably converts the DC power generated by your solar panels into usable AC electricity for your home, offering excellent performance in a small footprint.

Designed for Smaller Solar Arrays

What size inverter do you need for solar panels on a smaller roof? With a rated output of 1.5kW (1500W) and a maximum recommended DC input power of 2250W according to the product datasheet, the S1500-G2 is specifically tailored for modest solar installations. It features a single Maximum Power Point Tracker (MPPT), ideal for simple arrays where all panels are on a single roof face with consistent orientation and minimal shading.

High Efficiency in a Compact Package

Don't compromise on performance, even with a smaller system. The S1500-G2 boasts impressive efficiency ratings for its size, with the manufacturer's technical information stating a maximum efficiency of up to 97.3%. This ensures that a high percentage of the energy captured by your solar panels is converted into usable power, maximising your energy savings. Its low start-up voltage (60V) also helps it begin generating power earlier in the day.

Reliable and Easy to Install

Engineered for durability, this PV inverter features an IP65 rated enclosure, providing protection against dust and water ingress, making it suitable for various installation locations, including outdoors (ensure correct solar cabling and solar mounting systems are used). Its lightweight (5.4kg according to the specs) and compact design simplifies the installation process.

Monitoring Options

Keep track of your solar generation. The S1500-G2 features an LCD display for on-the-spot checks. As confirmed in the product literature, it also supports optional WiFi or 4G communication modules, allowing connection to the Fox ESS Cloud platform for remote monitoring via a smartphone app or web portal.
