In October, 2019, CYG Sunri supported the completion and operation of Huanggang PV-Storage-Charging Project of Hubei State Grid EV Service Company, providing an integrated solution of PV, storage and charging. The Project integrated many advanced technologies such as 70kWp carport PV power generation, 200kWh large-capacity energy storage, 600KW high-power intelligent group control DC charging stack, etc., and a smart microgrid system was set up. The system has realized the basic balance between local energy production and energy consumption load through energy storage and optimal allocation, and can flexibly interact with the public power grid according to needs and operate relatively independently. It uses new energy as much as possible to alleviate the impact of electricity consumption by charging piles on the power grid; The project has good ecological and economic benefits, as well as guiding significance for the construction of PV-storage-charging projects in the future.
