Description
Solis S6-EH1P8K-L-PLUS | Solarator Series 8kW Single-Phase Hybrid Inverter
Uninterrupted power, even in areas with grid instability.
Part of Solis's Solarator Series, the S6-EH1P8K-L-PLUS is a single-phase, low-voltage energy storage inverter built to operate seamlessly with a generator. It supports PV input up to 160% of its rated DC power, switches between on/off-grid in under 4ms, and handles 200% overload for 10 seconds off-grid — ideal for reliably starting motors, water pumps, and air conditioners.
