Description

Product Description

The Huawei SUN2000-30KTL-M3 String Inverter is engineered to optimise energy production and reliability in medium to large photovoltaic systems. It integrates four independent MPPT (Maximum Power Point Tracking) channels and eight DC inputs to extract maximum power from solar arrays with varied orientations and shading conditions. With a maximum conversion efficiency of up to 98.7 percent, the inverter minimises energy losses and delivers strong performance across a broad operating range. Built-in safety features include active arc fault detection (AFCI), Type II surge protection on AC and DC sides, anti-islanding protection and PID recovery to extend module life. The unit supports remote monitoring and diagnostics via Huawei’s FusionSolar platform using built-in communication interfaces and optional smart dongles for WLAN, Ethernet or 4G connectivity. Rugged IP66 protection and natural convection cooling enable long-term outdoor installation with minimal maintenance.
