GoodWe UT Series 320/350kW Solar Inverter
The GoodWe UT Series (320/350kW) is a new three-phase string inverter designed to enhance the profitability of utility-scale projects. Available with 12 MPPTs and 15 MPPTs, this series supports bifacial 182mm/210mm module access with a maximum string input current of 15/20A. Anti-PID and PID-recovery functions are included to mitigate and recover from PID effects. Engineered for demanding outdoor environments, the UT inverter operates reliably within a wide temperature range of -35°C to +60°C. This high-performance inverter offers enhanced safety, optimal LCOE, and cost-effectiveness, providing a future-proof solution for utility-scale PV projects.
Key Features
- Higher Yields: Features 20A max. DC input current per string, Anti-PID, and PID recovery.
- Lower Costs: Offers reactive power compensation at night and high-speed Power Line Communication (HPLC) for reduced wiring costs.
- Superb Safety & Reliability: IP66 and optional C5 protection ensure durability. It provides full power operation at high temperatures (350kW@40°C, 320kW@45°C).
- Grid Friendly: Ensures stable operation under weak grid conditions (SCR≥1.2) with a dynamic reactive power response <30ms.
