High-power 3-Phase Output (20 kW): The inverter delivers 20 kW AC output — suited for medium-to-large PV installations requiring significant power throughput (rooftop + commercial, or large residential + battery + loads).

Dual MPPT + Wide Voltage Range & Oversizing Flexibility: The S5-GR3P20K-v2 supports two MPPT inputs (string inputs), works over a wide DC voltage range (MPPT 160–1000 V, max input Voc up to 1100 V), and allows a DC/AC oversizing > 150%, making it compatible with high-wattage modern solar modules and large PV arrays.

High Efficiency & Grid-Tie Compliance: The inverter achieves a maximum conversion efficiency of up to 98.7%, with low THDi (<2%), high power factor (>0.99), ensuring efficient conversion and minimal losses — translating into better yield from solar panels.

Strong Safety & Protection Features + Rugged Build: Equipped with comprehensive protections: DC reverse-polarity protection, short-circuit protection, over-current/over-voltage protection, surge protection, anti-islanding, AFCI (arc-fault detection), insulation/earth-fault monitoring, temperature protection. The enclosure is rated IP66—dust-tight and water-jet resistant — suitable for outdoor / rooftop installations.
