3.3. System Introduction
SSLB1 Energy Storage System is consisted of 2 sets of M025100-A modules manufactured by Sunsynk.
In each M025100-A, there are 8 pcs of 100 Ah LFP cell originated from CATL. The overall system also
provides standard communication port, i.e. CAN and RS485, to monitor the working status and
communicate with upper machine as well as the Power Conversion System (PCS) in front. The system
schematic drawing is presented in Figure 2.
