TYPICAL SOLUTIONS FOR C&I PV STORAGE & CHARGING
3.1
CONFIGURATION
The project is designed to install 780 monocrystalline silicon solar panels with a standard power of 450Wp and a total capacity of 351kWp. The system adopted a 110kW string inverter, 20 solar panels connect to one string, and 13 strings connect to one inverter. The energy storage system adopts an independent outdoor cabinet design. PCS, battery modules, EMS, fire alarm system and HVAC are all concentrated in the cabinet. The system is mainly used in new energy integration systems, and can also achieve special functions such as peak-to-valley power adjustment and demand adjustment. Among them, the PCS capacity is 100KW, and the battery module capacity is 256kWh. The entire power station has three string inverters and an energy storage system, which are connected to the customer’s side through one 4in-1out AC combiner box. At the same time, according to customer needs, a 60kW DC charger and six sets of 7kW AC chargers are also equipped to supply power to the electric vehicles of the employees in the factory.
According to the above system analysis and product selection, the configuration list of the system is as follows:
