The photovoltaic installed capacity of this project is 20WMp and the energy storage capacity is 2MW/4MWh, which is the first time our company has undertaken a project in the plateau area. The photovoltaic system of this project adopts DC side combiner, and is connected to the grid through centralized photovoltaic inverters for converter boost. The energy storage system adopts a container type energy storage system, with the high-voltage side connected to the grid. Our products have withstood the severe test of long-term high altitude and low temperature, and have been fully recognized by users.
