The SG250HX is the world’s most powerful 1500Vdc string inverter, featuring a high capacity of 250kW. It comes with the high voltage of 1500Vdc and 800Vac, enabling cost saving on DC and AC cables. The product is of a maximum efficiency of 99% and compatible with bi-facial modules, offering a higher yield. The system features 12 MPPTs and a flexible block design allowing for up to 6.3 MW blocks, making it an ideal solution for hilly utility-scale applications.

Particularly with an ingress protection level of IP66 and an anti-corrosion grade of C5, the compact inverter is resilient in harsh conditions like desert and coastal areas. With smart forced air-cooling technology, the SG250HX can operate without derating at extremely high temperatures. The system is also inserted with fault diagnostic and IV-curve scan function, making it easier for operation and maintenance. Embedded anti-PID function will lead to much less module degradation. Also, the improved Power Line Communication (PLC) shall decrease installation cost without excessive communication wiring. In a bid to co-work with the probable storage segment, the inverter can be connected to storage systems with equipped storage interface.

“Sungrow is excited to bring forth another disruptive string inverter technology to Europe, maximizing ROI for our customers at unforeseen levels,” said Stefan Froboese, Technical Director, Sungrow EMEA.

Europe is witnessing an increase in activity for unsubsidized solar portfolios, whilst private renewable PPAs are poised to become more prevalent. Sungrow is dedicated to paving the way for grid parity across Europe with growing technical innovations and accelerating the global step to fulfill its corporate mission of “clean power for all”.
