Fox ESS H3-PRO-30.0 is a high-capacity three-phase hybrid inverter for large UK homes, farms and light-commercial sites where stable output and battery-ready control are essential. Its 3× MPPT architecture with a wide 150–850 V tracking window (full-load 230–850 V) extracts strong yield from multi-aspect or partially shaded arrays through typical British weather. Peak conversion efficiency reaches ≈97.8% with 99.9% MPPT accuracy, while the IP65 enclosure supports outdoor or plant-room installation.

Built for high-voltage LFP storage, H3-PRO-30.0 offers dual battery inputs (50 A + 50 A) for fast DC-coupled charge/discharge and scalable capacity. FoxCloud provides app and web monitoring via built-in Wi-Fi/LAN (optional 4G), with installer-grade interfaces including RS485, CAN, DRM, meter and USB for streamlined commissioning. Safety is certified to EN 62109-1/-2 with EMC compliance, and the inverter is suitable for UK G99 applications (subject to DNO approval). Dimensions 600 × 560 × 225 mm; weight ≈52.5 kg.

The Fox ESS H3-PRO-30.0 delivers large-scale hybrid power for commercial roofs, farms, and high-demand residential sites across the UK. With a rated AC output of 30 kW and advanced three-phase control, it offers the capacity and reliability required for heavy-load or multi-array solar installations. Specification data verified from Fox ESS H3 PRO datasheet (v2.1 – November 2024).

High-Efficiency Performance for British PV Systems

Designed with 3 MPPT trackers spanning a 150 – 850 V operating range (full-load 230 – 850 V), the H3-PRO-30.0 extracts optimum yield from complex or unevenly oriented solar arrays. Each tracker works independently to maintain string efficiency even under partial shading or low-irradiance conditions common in the UK. Conversion efficiency peaks at ≈97.8 %, supported by 99.9 % MPPT tracking accuracy, turning more sunlight into usable energy throughout the year.

Built for Reliability & Protection

The inverter’s IP65-rated aluminium housing resists rain, dust and corrosion, while adaptive fan cooling manages thermals during continuous high-power operation. Integrated protection systems include residual-current and insulation monitoring, anti-islanding logic, and surge arrestors (Type II AC / Type II DC). Certified to EN 62109-1 / -2 and compliant with IEC 61000-6-2 / -6-3 EMC standards, it meets the requirements for UK G99 grid connection and long-term reliability in British climates.

Key Features

30 kW three-phase hybrid inverter with 3 independent MPPT trackers.
Wide 150 – 850 V MPPT window (230 – 850 V full load) for flexible string design.
Peak efficiency ≈97.8 % / MPPT accuracy 99.9 % for maximum yield.
IP65 enclosure with intelligent fan cooling and quiet operation (< 60 dB).
Dual HV LFP battery inputs (50 A + 50 A) for fast DC-coupled storage.
Integrated Wi-Fi & LAN plus optional 4 G via FoxCloud monitoring.
Comprehensive protection suite - RCM, insulation, anti-islanding and surge arrestors.

If you’re wondering how the H3-PRO-30.0 performs on typical UK days, its broad MPPT range and precise tracking ensure steady generation through morning haze and overcast conditions when less advanced inverters begin to lose efficiency.

Specification data verified from Fox ESS H3 PRO documentation (v2.1 – November 2024).

Seamless Integration with Solar Panels & Battery Storage

The Fox ESS H3-PRO-30.0 is designed for large-scale hybrid installations combining solar panels and battery storage. Its dual high-voltage LFP battery inputs (50 A + 50 A) provide rapid DC-coupled charge/discharge, reducing conversion losses and improving round-trip efficiency. Three independent MPPTs offer full flexibility for multi-aspect rooftops or commercial canopies, while export-limiting and three-phase load balancing maintain stable operation under UK G99 conditions.

Smart Monitoring & Advanced Connectivity

FoxCloud gives installers and users real-time control and visibility through app and web platforms. Standard Wi-Fi & LAN connectivity comes built-in, with optional 4 G modules for remote sites. A comprehensive communication suite - RS485, CAN, DRM, meter, and USB - supports smart-meter feedback, BMS integration and firmware updates. Automatic logging ensures simplified maintenance and performance analysis over the inverter’s lifetime.

Compact Design & Installer Practicality

Despite its high output, the H3-PRO-30.0 maintains a manageable footprint of 600 × 560 × 225 mm and weighs around 52.5 kg. The IP65 housing and adaptive fan-cooling system safeguard electronics against heat and moisture while keeping operating noise below 60 dB - ideal for plant rooms or external wall installations where quiet reliability is essential.

Installer Guidance & System Notes

String design & MPPT layout

Use all three MPPT trackers to separate roof orientations or string lengths. Maintain DC input between 150 and 850 V (230 – 850 V at full load) and follow the Fox ESS datasheet for current and short-circuit limits.

Battery configuration & sizing

Connect dual HV LFP battery stacks to the 50 A + 50 A channels for high-speed charging. Begin with storage sized to daily consumption and expand later - the inverter scales without hardware changes.

Grid compliance & safety

Certified to EN 62109-1 / -2 and EMC IEC 61000-6-2 / -6-3, with built-in RCM, insulation monitoring, anti-islanding and Type II AC/DC surge protection. Suitable for UK G99 applications (subject to DNO approval).
