CE certificate
For thin film PV panel
Rated Output Power,250KW
General Descriptions
SG250KLV is specially-designed for Amorphous Silicon. It can be continuously operating at rated power under +55°C without derating. It is the ideal product used for string-connected large PV power station to simplify PV power plant design. In addition, wider input voltage range ensures more combinations of the PV arrays. It is one of the highest cost-effective grid-connected inverters in the world.
