Sineng 20kw On-Grid Three Phase Solar Inverter

The Sineng SN20PT is a high-efficiency, three-phase 20 kW on-grid solar inverter engineered for residential and small-to-medium commercial PV systems. With dual MPPT trackers and a wide MPPT voltage range, it ensures optimal energy harvest from diverse panel configurations, even in partially shaded or varied roof orientations.

Built with advanced grid management and protection features, the SN20PT offers superior reliability and safety. It includes anti-islanding protection, DC reverse polarity protection, integrated surge protection (Type II on both AC and DC sides), insulation monitoring, and optional PID recovery, ensuring safe and uninterrupted operation in all conditions.

Designed with installer and user convenience in mind, the inverter supports multiple communication interfaces (RS485, Wi-Fi, 4G, Ethernet) and is housed in a compact, IP66-rated enclosure that resists dust and water ingress. Its fanless cooling design ensures quiet operation and reduced maintenance over time.

Achieving up to 98.6% efficiency, the SN20PT minimizes energy loss during DC to AC conversion, delivering more usable power to the grid. It operates effectively in temperatures ranging from -25°C to 60°C and at altitudes up to 4000 meters, making it a versatile solution for diverse installation environments.
