Sungrow, an inverter solution supplier for renewables, presents its UL 1741-SA certified 1500V string and central PV inverters as well as C&I and utility energy storage system (ESS) at the Solar Power International 2017 in Las Vegas, NV, USA.
Both of the inverters feature high efficiency and the ability to adapt to asevere environment. The SG125HV, which has received UL 1741-SA certification recently, is the world's most powerful 1500Vdc string inverter, featuring a high capacity of 125kW. As a turnkey station for 1500Vdc systems, the SG2500U is the first UL 1741-SA certified central inverter. Earlier this month, Sungrow has announced that it has won a deal supplying 205MW of SG2500U for a utility-scale project in California, USA.
As for ESS, showcased is the commercial and utility-scale 250KW-2/4 hours turnkey solution which is specifically designed for C&I projects in North America. It features a small footprint, flexible installation, easy O&M, powerful grid functions, and can be configured from 250kW to 1MW.
The DC-coupled ESS solution for PV plus storage projects is also introduced at the show. The system, which has been installed at a 100MW and a 20MW PV power plant, greatly improves the predicted accuracy of PV power, ensuring smooth PV power output and enhance efficiency. Also on show were batteries supplied by Sungrow-Samsung SDI joint venture.
