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

The Solis S6-EH3P50K-H is a 50 kW three-phase hybrid energy storage inverter designed for residential, small-scale 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 100 kW 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 150–850 V.

The S6-EH3P50K-H integrates seamlessly with Li-ion battery systems (150–800 V), supporting two independent battery ports with a maximum charge/discharge power of 55 kW and a current of 140 A across both ports. It provides intelligent load prioritization for critical loads, battery reserve management, and UPS-like backup capability with grid transition times under 10 ms. The inverter also supports parallel operation of multiple units up to 500 kW and optional integration of 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, Type II surge protection), an IP66 ingress protection rating, and intelligent fan cooling. The operating temperature range is −25 to +60°C, with a maximum altitude rating of 4000 m.
