Solis S5-GR3P grid-tied inverter (3–20) kW · three-phase · 3K

Overview

Solis S5-GR3P (3–20 kW) is a three-phase grid-tied inverter for solar power plants built for self-consumption or the feed-in tariff. It is the optimal solution for large private houses, residences, commercial sites, vehicle service stations, hotels and production workshops with a three-phase supply.

The inverter operates without batteries, routing the generated solar energy straight to the site's three-phase load. This ensures balanced phase distribution, a substantial reduction in daytime electricity bills and the fastest possible payback for the solar power plant, with no battery investment.

The model features 2 independent MPPT trackers supporting high input current (up to 16 A per string). This allows PV modules to be arranged flexibly across different roof pitches and modern high-power PV modules to be used. With efficiency of up to 98.7% and a low start-up voltage, the inverter extracts maximum generation throughout the daylight hours.

Solis S5-GR3P stands out for high reliability and quiet operation. The unit has built-in arc-fault protection (AFCI) and surge protection on the AC and DC sides, and supports intelligent Wi-Fi/GPRS monitoring and export limitation (Zero Export).
