Product Features
VST-22K-30K-M3 Series 22-30kW Three Phase On-grid Inverter Overview
The VEICHI VST-22K-30K-M3 series three-phase grid-tie inverters, suitable for commercial and industrial applications, come in three power ratings from 22kW to 30kW. High-performance internal components minimize energy loss, achieving up to 98.8% maximum efficiency. With 3 MPPT trackers, a maximum PV input current of 36A, and an MPPT voltage range of 100V–1080V, they support high-power PV modules for longer generation time and higher returns. Multiple grid-tie certifications enable global applicability. The IP66 protection rating, intelligent grounding detection, and lightning protection contribute to the stable development of distributed PV systems.
