Sungrow, the global leading inverter solution supplier for renewables, rolled out flagship PV and energy storage product solutions at the ongoing Smart Energy Virtual Show, showing latest advanced technologies for multiple applications in a more flexible, informative virtual networking platform. 


Latest turnkey station SG6250HV-MV


The turnkey station SG6250HV-MV for 1500Vdc system integrates two units of outdoor central inverter SG3125HV-30 with medium-voltage transformer and other components in a 40-ft container, minimizing the cost on transportation and installation. Given the three-level topology technology, the maximum inverter efficiency reaches 99%. As a brand-new outdoor central inverter, it is strategically designed with DC/AC ratio up to 1.8, enabling cost-saving on Balance of System (BoS) at USD$ 2 million for a 100MWp project.

Featuring an optimal protection level of IP65 and anti-corrosion capacity of C5, the brand-new outdoor solution is resilient in harsh conditions. Equipped with smart forced air-cooling technology, the solution can operate without derating even when the temperature is up to 50 degrees Celsius, making solar projects more productive and cost-effective. The solution is compatible with the DC-coupling energy storage system, enabling 60% of the rated power charge from grid. Complying with the most demanding international grid codes, the solution contributes the quality and stability of the electric system.
