应用案例 Application Case:NL15F-PV700


Sinowatt has developed HVDC distributed PV ESS for photovoltaic power generation on Dutch farms with the support of the European Agent of Sinowatt ATEPS Nederland BV. The project is further supported by the Dutch government and local electric power company. The systems support smart electricity trading which greatly shortens clients' investment payback period and have been applied on a number of Dutch and other European farms.
