Solis S6-GR1P3K Single-Phase Grid-Tied Inverter

The Solis S6-GR1P3K is a single-phase grid-tied inverter designed for residential solar installations. It features dual MPPT trackers with a precise MPPT algorithm, high-frequency switching technology, and a wide voltage range (90–520 V) with a low startup voltage of 120 V.

This inverter achieves a maximum efficiency of 97.3% and is equipped with integrated AFCI arc detection, an Export Power Manager (EPM), and comprehensive protection, including DC reverse polarity, short-circuit, and anti-islanding features. It operates on both 50 Hz and 60 Hz grids, with a power factor greater than 0.99 and THDi below 3%.

The transformerless design keeps the unit compact (310 × 543 × 160 mm) and lightweight at 11.2 kg, with natural cooling and IP66 ingress protection. Output is via a quick-connect plug; communication is via RS485, with optional Wi-Fi, LAN, or GPRS connectivity.
