Solis S6-GR1P 3.6K Single-Phase Grid-Tied Inverter

The Solis S6-GR1P 3.6K is a single-phase grid-tied inverter designed for residential solar systems. It features 2 MPPT inputs with a precise MPPT algorithm, achieving a maximum efficiency of 97.3% and a European efficiency of 97.1%. The inverter includes integrated AFCI protection for arc-fault detection and an Export Power Manager (EPM) for grid-friendly operation.

With a rated output power of 3.6 kW and a maximum input current of 14 A per string, it supports a wide DC voltage range of 90–520 V (MPPT) and a low startup voltage of 120 V. The transformerless design with natural cooling keeps the unit compact (310 × 543 × 160 mm) and lightweight at 11.2 kg, while meeting stringent grid connection standards including G99, VDE-AR-N 4105, and EN 50549-1.

The inverter is equipped with RS485 communication (optional Wi-Fi/GPRS via datalogger) and an LCD display for local monitoring. It provides comprehensive protection, including DC reverse-polarity, short-circuit, surge, and temperature protection, with an IP66 ingress protection rating and operation in ambient temperatures from −25 to +60 °C.
