Description
Overview
The Solis S6-EH3P29.9K-H-AU is a 29.9kW three-phase high voltage hybrid inverter from the Solis S6-EH3P(29.9-50)K-H-AU series, designed for three-phase solar and battery storage systems. The series covers 29.9kW to 50kW models.
Three MPPTs with 40A per tracker accept a PV array of up to 59.8kW. Two independent high voltage battery ports (150–800V) take 70A each, 140A combined, and the backup output is rated at the full 29.9kW. A smart port adds a generator, AC-coupled inverter or smart load.
