Description

Product Description

The Huawei SUN2000-25KTL-M5 string inverter is designed for efficient DC-to-AC conversion in medium- to large-scale solar installations. It supports up to 37.5 kW of PV input power with a wide MPPT operating range and dual independent trackers for optimal energy harvesting under varied site conditions. Built-in protections include arc fault detection, anti-islanding protection, DC/AC surge protection, residual current monitoring, and PID recovery, enhancing safety and reliability. The inverter’s IP66 weather-resistant enclosure and smart air cooling enable long-term outdoor operation. Integrated communication interfaces and compatibility with Huawei’s FusionSolar platform allow remote monitoring, diagnostics, and performance optimisation to improve uptime and system performance.
