GoodWe, a renowned global provider of solar products and energy solutions, has launched its new three-phase 1,500V utility string inverter, the UT (320/350kW). The inverter is designed to meet the demands of large-scale power plants, offering high power efficiency, streamlined operation and maintenance (O&M), and reliable system stability. With this addition, GoodWe strengthens its utility portfolio by providing increased capacity and significantly reducing Levelized Cost of Energy (LCOE).
The series offers options of 12 MPPTs and 15 MPPTs and boasts a maximum efficiency of 99.01%. With a maximum string input current of 15/20A, it is compatible with bifacial modules, optimizing energy yields for power plants.
The UT series provides anti-Potential Induced Degradation (PID) and PID-recovery functions, effectively mitigating and recovering energy losses caused by PID effects, especially in high-temperature and high-humidity conditions. With an IP66 rating and up to C5 protection, the inverter demonstrates resilience in harsh environments. The 320kW UT can operate without derating for ambient temperature of up to 40 degrees Celsius.
The use of mid-band power line communication (HPLC) technology decreases installation costs without extra communication wiring. The UT can also be equipped to compensate reactive power during the nighttime to maintain the voltage stability of the system, eliminating the need for a costly external compensation system.
For system monitoring, the communication devices, such as SCU3000 series, enable data acquisition and transmission within the power plant. Furthermore, the solution facilitates comprehensive O&M through a station-level monitoring platform known as GoodWe’s SolarOS, making remote system management accessible and effective.
