On June 14, 2022, Shanghai Electric Power issued an announcement: the company won the bid for the distributed photovoltaic development rights of the 62MW base station of the Zhejiang Branch of China Tower Co., Ltd. (hereinafter referred to as "China Tower"). The project is located in Zhejiang Province and involves about 11,500 computer room roofs and 6,900 cabinets of China Tower in Zhejiang. It is planned to build about 62MW of distributed photovoltaics. It uses DC micro-grid power supply technology to provide green power for the tower base station, and the power generation can reach 100% consumption.

What is Rapid shutdown Device?Rapid shutdown is an electrical safety requirement set by the National Electrical Code (NEC) for solar panel systems. Rapid shutdown is written into NEC as required by the National Fire Protection Association (NFPA). We hope that the fire hazards will not happen, but if
