4. BATTERY POWER AND COMMUNICATION CONNECTIONS
Each SUN-BATT-5.12 has two pairs of power cable terminals, two P+, and two P-. The connec-
tion terminals of each pair have the same function.
Single Module
In a single module application, any of the terminals of each pair can be used.
Parallel System
Multiple batteries can be connected in parallel to expand the capacity and power. When using
multiple batteries in parallel, one will operate as a master and the others as slaves. One of the
Master pack P+ terminals should connect to the PCS, and the other should connect to another
battery for capacity expansion.
One of the P- terminals of the last Slave pack should connect to PCS, and the other should
connect to another battery for capacity expansion.
For the other Slave packs, each P terminal should be connected to another battery's terminal.
4.1. Parallel Cascade Connection
Applicable scenario:
PCS with 100A charge/discharge current connect to SUN-BATT-5.12.
4.1.1. Power Cable Wiring Instructions
The connection to the protection devices should use the P+ terminal from the Mas-
ter pack and the P- terminal from the last Slave pack.
