Fox ESS H3-8.0-E 8kW Inverter: The Powerful Three-Phase Hybrid Solar Inverter

The Fox ESS H3-8.0-E delivers a significant 8kW of three-phase hybrid inverter power, making it an excellent choice for larger UK homes or small businesses with three-phase supply. This unit intelligently orchestrates energy flow between extensive solar panel systems, compatible high voltage batteries, and the grid, maximising self-consumption and providing robust backup power capability.

Flexible Solar Input with Asymmetric Dual MPPT

How to choose a solar inverter for uneven panel strings? The H3-8.0-E provides a unique solution with its dual MPPT design, configured for 2 strings on one MPPT and 1 string on the other, as detailed in the manufacturer's datasheet. This allows excellent flexibility for larger or unusually configured solar panel arrays, such as those utilising a large main roof area and a smaller secondary area, while still optimising the power harvest from each section independently (Max input current 26A/14A).

Integrated High-Voltage Battery Management

This hybrid inverter is designed for seamless integration with modern battery energy storage. It supports compatible high-voltage LFP batteries (180-600V range) and efficiently manages charging and discharging up to 26A, according to the product specification sheet. Store plentiful solar energy generated during the day to power your property during peak hours or overnight, significantly reducing your reliance on the grid.

Enhanced Energy Savings & Efficiency

Maximise the benefit of your solar investment. The H3-8.0-E boasts high operational efficiency (Max. Efficiency 97.80% listed in technical data), minimising energy waste. By prioritising self-consumption of stored solar energy, it directly cuts your electricity bills. The inverter's smart capabilities also enable potential optimisation strategies involving time-of-use tariffs, allowing programmed charging from the grid during low-cost periods for later use.

Substantial Backup Power (EPS)

Gain resilience against power outages. When paired with a compatible battery system, the H3-8.0-E provides a strong 8kVA three-phase Emergency Power Supply (EPS) output. With a switchover time documented as less than 20ms, it ensures near-instantaneous power to keep essential three-phase or single-phase circuits operational when the grid goes down.

Durable Build & Smart Monitoring Features

Engineered for reliability, the H3-8.0-E features an IP65 protection rating, ensuring its suitability for outdoor installation (using correct solar cabling and mounting). Monitor your system's performance in detail – including generation, storage, and consumption – remotely through the Fox ESS Cloud platform via optional WiFi, LAN, GPRS or 4G connectivity modules.
