GoodWe expands utility portfolio with launch of 320/350kW string inverter

By GoodWe

GoodWe has launched its new three-phase 1,500V utility string inverter, the UT 320/350kW,  designed to meet the demands of large-scale power plants, offering high power efficiency, streamlined O&M and reliable system stability.

The UT series offers options of 12 and 15 MPPTs and 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 product features anti-Potential Induced Degradation (PID) and PID-recovery functions, effectively mitigating 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 and the 320kW version can operate without derating in ambient temperatures of up to 45 degrees Celsius.

The use of mid-band power line communication (HPLC) technology decreases installation costs without extra communication wiring and the UT series can also be equipped to compensate reactive power during nighttime to maintain the system’s voltage stability,  eliminating the need for a costly external compensation system. The UT inverter supports a low SCR of 1.0, which ensures power plant stability even in weak grid conditions.

The product, when paired with other essential components for utility projects offered by GoodWe, such as the MV station (MVS), and advanced communication devices, can form a one-stop solution that excels in various outdoor environments. This integrated solution optimizes energy yields and simplifies O&M, maximizing return on investment for plant owners.

The MVS, conveniently housed in a transportable container, incorporates essential LV and MV switchgears and a transformer to ensure seamless power transformation. Within the system, once the inverter converts DC energy to AC, the MV station further transforms the AC energy voltage for easy grid connection and distribution.

For system monitoring, communication devices, such as the SCU3000 series, enable data acquisition and transmission within the power plant. The solution facilitates comprehensive O&M through the GoodWe SolarOS station-level monitoring platform, making remote system management both accessible and effective.

“With the introduction of the UT inverter, we have consolidated our ability to meet the diverse requirements of EPCs, power plant developers and investors, assuring them a secure return on investment. Looking forward, GoodWe remains committed to advancing technological innovation, delivering a more bankable product portfolio and turnkey solutions for large-scale solar projects,” commented company VP Ron Shen.
