Microgrid Energy Storage System

 

The microgrid battery storage system is an electrical energy storage device used in the microgrid, which can store renewable energy such as solar energy, so as to provide backup power support for the load when the power supply is insufficient or the grid fails. It is an indispensable and important part of microgrids.

 

 

 

The whole Microgrid energy storage system is 1MW/1MWh,the actual battery energy of a single container energy storage system is 1MW/1.135MWh. The energy storage system uses 21 pcs single cells connected in parallel to form a small battery module, 12 pcs small battery modules connected in series to form a battery module, two battery modules connected in series to form a battery box, and eight battery boxes connected in series to form a battery pack. The system has 16 battery strings(including BMS),2 sets combiner boxes,2 sets 500KW PCS, 1 set EMS, air conditioner, fire extinguisher system and other accessory equipment.

Remark: Customers have to purchase a 315V/22KV isolated step-up transformer. (The transformer is mainly used to raise system voltage from 315V to 22kV)
