Solis S6-EH3P8K-H-AU 8kW Three Phase Hybrid Inverter, High Voltage Battery

Overview

The Solis S6-EH3P8K-H-AU is a 8kW three-phase high voltage hybrid inverter from the Solis S6-EH3P(5-10)K-H-AU series, designed for solar and battery storage systems on three-phase supplies. The series covers 5kW to 10kW models.

Four MPPTs accept a PV array of up to 16kW (200% of rated output), and the 120–600V battery port charges and discharges at up to 8kW / 50A. A separate backup port supplies 8kW continuously and supports unbalanced three-phase loads.
