Fox ESS G9 9kW Inverter: The Maximum Power Single Phase Solar Inverter for UK Homes

The Fox ESS G9 inverter is designed for homeowners who require significant power from their solar inverter system. As a top-tier model in the G-Series range, this 9kW single-phase string inverter delivers exceptional efficiency and robust performance, perfectly suited for very large residential solar panel arrays. It ensures optimal conversion of your solar DC power into usable AC electricity for your home.

Triple MPPT for Unmatched Flexibility

How to choose a solar inverter for maximum yield on complex roofs? The G9's standout feature is its three independent Maximum Power Point Trackers (MPPTs), confirmed by the official product datasheet. This advanced configuration provides unparalleled flexibility for installations with solar panels on multiple roof orientations (e.g., east, west, and south) or those affected by intricate shading patterns. Each MPPT independently optimises its string, ensuring the absolute maximum energy harvest from the entire system.

Peak Solar Inverter Efficiency

Maximising your return on investment requires high efficiency. The Fox ESS G9 excels here, with technical documentation stating a maximum efficiency of up to 97.8%. This top-level performance minimises energy losses during the DC-to-AC conversion, meaning more of the power generated by your extensive solar array directly contributes to reducing your electricity bills.

Durable & Weatherproof Construction

Built to last, the G9 inverter features a rugged IP65-rated enclosure. This guarantees protection against dust and water, making it suitable for outdoor installation in varying UK weather conditions. Reliable performance is further supported by its transformerless design and natural convection cooling. Remember to use high-quality solar cabling and a professional solar mounting system for installation. Fox ESS inverters typically come with substantial manufacturer warranties.

Integrated Smart Monitoring

Monitor your high-capacity system with ease. The G9 supports optional WiFi or 4G communication dongles, enabling connection to the FoxCloud V2.0 monitoring platform, as detailed in the product information. This gives you access to real-time performance data, historical trends, and system alerts via a user-friendly smartphone app or web portal.
