Sungrow signs storage inverter supply agreement for 30 MWh storage project in Japan


Sungrow, the Chinese firm that specializes in solar inverters and storage solutions, signed last week a strategic partnership to deliver a containerized, turnkey storage solution to a new project in Hokkaido, Japan.

In total, Sungrow will supply 23 containers that consist of its storage inverters, an energy management system (EMS) and NCM lithium batteries, which have been developed under the recent Sungrow-Samsung SDI joint venture.

This supply deal is the second occasion in which Sungrow has delivered its energy storage systems to a project in Japan. Last year an inaugural 1 MW/3.3 MWh project was completed using this turnkey solution. This installation, located in Aomori Prefecture, has been up-and-running since November.

The NCM lithium batteries supplied within the containers boast high energy density, a long life and a deep charging and discharging function that makes them ideal for grid-tied storage solutions.

Hank Wang, Sungrow’s VP for international business development, told pv magazine at PV Expo last week that the company is keeping an open mind on which storage technologies to support and develop. “Aside from the JV we have with Samsung, we are also building PCS units ourselves, and are fully open to all types of storage technology in order to be able to diversify and reach different areas of the market,” Wang said.
