Solis S5 20kW 3-Phase Dual MPPT Grid-Tied Inverter (DC)

Solis S5 20kW 3-Phase Dual MPPT Grid-Tied Inverter (DC)

The Solis S5 20kW 3-Phase Dual MPPT Grid-Tied Inverter is a high-performance commercial solar inverter engineered to maximize energy production, efficiency, and system reliability. Designed for medium to large-scale commercial and industrial photovoltaic (PV) installations, this advanced inverter delivers 20kW of rated AC output power, supports up to 30kW of PV input, and achieves an impressive 98.7% maximum efficiency.

With four 16A PV string inputs, dual MPPT technology, and an ultra-wide operating voltage range, the S5 Series ensures optimal power generation even under varying weather conditions and complex rooftop layouts. Integrated safety features, including DC Arc-Fault Circuit Interruption (AFCI), Type II surge protection on both AC and DC sides, and reverse-polarity protection, provide superior system protection and long-term reliability.

Built to withstand harsh outdoor environments with an IP66-rated enclosure, the inverter supports remote monitoring and firmware updates through SolisCloud (with an optional data logger), making system management simple and efficient.

Ideal for commercial buildings, warehouses, factories, agricultural installations, schools, and large residential projects requiring dependable three-phase solar power.
