Solis S6-EH3P50K-H 50kW Three-Phase Hybrid Energy Storage Inverter

The Solis S6-EH3P50K-H is a 50kW three-phase hybrid energy storage inverter designed for residential, small industrial, and commercial PV installations. It supports both DC and AC coupling for flexible retrofits and system expansions, with a maximum PV input power of 100kW and four MPPT trackers managing up to eight input strings. The inverter achieves a maximum efficiency of 97.8% and features a wide MPPT voltage range of 150–850V.

The S6-EH3P50K-H integrates seamlessly with Li-ion battery systems (150–800V), supporting two independent battery ports with a maximum charge/discharge power of 55kW and current of 140A across both ports. It provides intelligent load prioritization for critical loads, battery reserve management, and UPS-like backup capability with grid transition times under 10ms. The inverter also supports multi-unit parallel operation up to 500kW and integrates optional diesel generator or wind power inputs.

Key features include a 7-inch industrial LCD display with Bluetooth and app connectivity via SolisCloud, integrated arc flash detection (AFCI 2.0 optional), comprehensive protection (anti-islanding, DC reverse-polarity, surge protection Type II), IP66 ingress rating, and intelligent fan cooling. Operating temperature range is −25 to +60°C with a maximum altitude rating of 4000m.
