Solis S6-EH3P50K-H – 50kW Three-Phase High-Voltage Hybrid Solar Inverter

The Solis S6-EH3P50K-H is a 50kW three-phase high-voltage hybrid inverter designed for large residential, commercial, and industrial solar systems. It has 4 MPPT trackers and accepts up to 96kW of usable solar power. Two independently controlled battery ports connect to high-voltage lithium-ion batteries. It can also run as a grid-tied inverter without batteries, and up to 6 units can be connected in parallel for larger systems. The IP66 rating allows indoor or outdoor installation.
