Sungrow introduces SG250HX a 1500Vdc string inverter at InterSolar

Sungrow introduced SG250HX a 1500Vdc string inverter at Intersolar Europe 2019. The 250kW inverter, designed for optimal performance, is now available for pre-sale.

Sungrow touts SG250HX as the world’s most powerful 1500Vdc string inverter.

It comes with the high voltage of 1500Vdc and 800Vac, enabling cost saving on DC and AC cables. According to the company 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 which makes 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, said the company in a statement.
