Description
Solis S6-EH3P15K02-NV-YD-L | Solarator Series 15kW Three-Phase Hybrid Inverter
Uninterrupted power for demanding three-phase solar and storage installations.
Part of Solis's Solarator Series, the S6-EH3P15K02-NV-YD-L is a three-phase, low-voltage energy storage inverter built to maximize solar utilization and deliver seamless backup power. It supports PV input up to 160% of its rated DC power, switches between on/off-grid in under 10ms, and handles 200% overload for 10 seconds off-grid — enough to reliably start motors, water pumps, and air conditioners.
