VST-75K-110K Series 75-110kW Three Phase On-grid Inverter Overview
The VEICHI VST-75K-110K series three-phase grid-tie inverters are suitable for various commercial, industrial, and distributed PV plants, offered in four power ratings from 75kW to 110kW to meet diverse project requirements. High-performance internal components minimize energy loss, achieving up to 98.8% maximum efficiency. With up to 9 MPPT trackers, a maximum PV input current of 40A, and an MPPT voltage range of 100V–1080V, they support high-power PV modules for longer generation time and higher returns. Noise level ≤40 dB. Multiple grid-tie certifications ensure global suitability. The IP66 protection rating, intelligent grounding detection, and lightning protection contribute to the stable development of distributed PV.
