Please follow below steps to connect the batteries:
Step 1
-
Install a DC Circuit Breaker for positive (+) battery cable. The rating of the
DC Circuit Breaker must be at least
140Amp for POWERBACK PB3000S,
120Amp for POWERBACK PB5000S to
guarantee safe operation without
interruption. Keep the DC Circuit
Breaker off.
Step 2
- Connect a red cable to
BAT+
terminal, and a black cable to
BAT -
terminal of the inverter.
Knock off below “BAT+” and “BAT-” holes, cross red cable via “BAT+” hole and
cross black cable via “BAT-“ hole.
Step 3
- Connect the above mentioned red cable to the battery’s positive (+)
terminal and black cable to battery’s negative (-) terminal.
Step 4
- After AC input and output wires are connected, switch on the DC Circuit
Breaker.
Note:
Make sure the battery voltage meets the inverter’s specification:
POWERBACK PB3000S supports 24VDC battery system; POWERBACK
PB5000S supports 48VDC battery system. And use at least 200Ah capacity
battery for POWERBACK PB3000S & POWERBACK PB5000S.
