Additional Details
The ST-VI3000-800 is a 3 kW, 800 V high-voltage vehicle inverter that converts an 800 V traction battery bus (600–876 Vdc) into clean 220 Vac ±5% pure sine-wave power at 50 ±1 Hz, with total harmonic distortion held to ≤5% and 90% conversion efficiency.
Built for harsh on-vehicle service, the unit is IP6K5-sealed and rated -40 to +85 °C (derating above 55 °C), with 10–95% RH non-condensing humidity tolerance and operation up to 3000 m altitude. It uses a dual-input architecture — an HV main feed plus a low-voltage auxiliary supply — and carries staged overload protection. The ST-VI3000-800 is currently under A-sample testing on a Suzhou Zaihe 49 T tractor.
