Description

The GoodWe GW25K-SDT-30 is a 25kW three-phase string inverter designed for commercial and industrial PV systems with high-power modules. It features three MPPT trackers with six string inputs, enabling optimised performance on complex roof layouts and multiple orientations.

The inverter delivers a maximum efficiency of 98.7% and includes integrated safety features such as PV string current monitoring, insulation resistance detection, anti-islanding protection, and Type II surge protection on both AC and DC sides. Optional AFCI 3.0 functionality provides arc fault detection capability. Smart fan cooling keeps the unit silent during operation with noise emissions below 45 dB.

Communication options include RS485, WiFi, LAN, and Bluetooth (optional), supporting Modbus TCP/RTU protocols for system integration and monitoring. The inverter is non-isolated, operates at -30 to +60 °C, and carries an IP66 ingress protection rating suitable for outdoor installation.
