VST-5K-10K-M3 Series 5-10kW Three Phase On-grid Inverter Overview
The VEICHI VST-5K-10K-M3 series three-phase grid-tie inverters, available in four power ratings from 5kW to 10kW, are designed for residential applications. Precise MPPT algorithms reduce energy loss, reaching up to 98.8% maximum efficiency. With 3 MPPT trackers, a maximum PV input current of 18A, and an MPPT voltage range of 100V–1080V, they support high-power PV modules for extended generation time and increased returns. Communication via Wi-Fi, 4G, GPRS, and Bluetooth enables remote monitoring. The IP66 protection rating, along with intelligent grounding detection and lightning protection, ensures reliable operation in harsh environments and safeguards household safety.
