4. BATTERY POWER AND COMMUNICATION CONNEC
TIONS
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 bat-
teries 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.
