Description

The Solis S6-EH3P29.9K-H is a three-phase hybrid energy storage inverter rated at 29.9 kW output, designed for residential, small industrial, and commercial PV installations. It combines on-grid, off-grid, and backup power capabilities with support for both DC and AC coupling, making it suitable for flexible retrofits and system expansions.

The inverter features 3 independent MPPT trackers with 6 input strings, accommodating a maximum PV array size of 60 kW and rated voltage of 600 V. It incorporates two independent battery ports for flexible configurations, supporting Li-ion batteries in the 150–800 V range with maximum charge/discharge power of 32.1 kW and current of 140 A (parallel). On-grid to off-grid transition is achieved in less than 10 ms, with 160% overload capacity for 2 seconds in off-grid mode.

Additional features include a 7-inch industrial-grade LCD display with Bluetooth and APP control, MC4 quick-connect PV terminals, integrated DC and AC surge protection, IP66 ingress rating, and intelligent fan-cooling for operation in ambient temperatures from –25 to +60 °C. The inverter supports multi-unit parallel operation up to 500 kW and includes generator input compatibility across 20–100% of rated power.
