The SUN2000-330KTL-H2 is Huawei’s high-power smart string inverter for utility-scale and large C&I installations that require compact high-density power conversion, detailed string-level visibility and robust safety. The unit delivers up to 330 kVA (max apparent power) with a nominal AC active power rating shown on the datasheet and supports a 1,500 Vdc PV array architecture. It includes 6 independent MPPTs (MPPT operating range 500–1,500 V; start voltage 550 V), high short-circuit tolerance (up to 115 A per MPPT), and smart string-level disconnectors for faster O&M and safer onsite work. The inverter is built for outdoor use (IP66), wide temperature operation (-25 °C to +60 °C), smart air cooling and is suitable for high-altitude deployments up to 4,000 m.
