Three Phase Solar Inverter

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.
