## Description
**Sungrow SG20RT-P2** is a reliable and high-power 20 kW solar power solution designed to efficiently manage large flows of electrical energy. Thanks to the technical improvements implemented in the P2 series, the device supports up to 16 A DC input current per string, allowing you to maximize the full potential of modern large-format (M10/M12 cell) solar modules without power clipping.

The inverter is equipped with **2 independent MPPT trackers** with a total of 4 string inputs (2/2), providing exceptional flexibility when designing high-capacity PV systems on different roof pitches or orientations. A low startup voltage enables the system to begin power generation early in the morning and maintain it until late in the evening.

In terms of safety, Sungrow has integrated cutting-edge technologies: the AI-powered **AFCI (Arc Fault Circuit Interrupter)** system detects hazardous electric arcs in a fraction of a second and disconnects the circuit. In addition, the inverter comes factory-equipped with Type II surge protection devices (SPDs) on both the DC and AC sides. Thanks to intelligent cooling and an **IP65** protection rating, the unit operates reliably and is suitable for installation outdoors as well as in industrial or utility rooms.

Generation data is accessible in real-time via the included Wi-Fi / Ethernet communication module and the free **iSolarCloud** platform.
