SUN8000 Series-500KTL


SUN8000 has leading efficiency up to 98.7% with “T” type three level topology. The reliability is improved significantly with modular design and intelligent dormancy that also optimizes efficiency at low irradiation. This product series supports two-winding transformer for grid-connection with common-mode current rejection algorithm, which helps to save 5~10% of the transformer investment.

SUN8000 is an advanced solution for large-scale PV plant application.

This product series meets Germany BDEW MV directive, CEI 0-16 and China Golden Sun certification, fulfills the requirements of LVRT and ZVRT. It has passed the strictest verification tests which ensures SUN8000’s good environment adaptability for applications in the area of high altitude, hot or cold environment.
