Description
Overview
The Solis S5-GR3P15K is a 15kW three-phase grid-tied solar inverter from the Solis S5-GR3P(5-20)K series, a transformerless string inverter range for three-phase sites. The series covers 5kW to 20kW models.
Two MPPTs taking up to four strings, with 32A per tracker, support large modules, and up to 20kW of PV can be connected. The inverter supports export power control, and can be registered on SolisCloud by scanning for remote upgrade and control.
