Connecting batteries together in parallel:
1
When connecting multiple TROPPO batteries to a single inverter/charger follow the steps below.
Confirm status of the battery: On each battery switch ON the OVERCURRENT PROTECTION MCB
and confirm that the display and indicator light illuminates (blue light in grey battery). By looking
at the display, confirm that the battery voltage is between 48.0V
DC
and 55.2V
DC
. It is recommended
that the voltages of all the batteries are within 0.5 volts of each other to avoid high current flows
between the batteries once they are all connected in parallel. Note that the BMS in the batteries
will not allow electrical connection if the voltage difference between the batteries is greater than
2-3 volts. Bring the battery voltages closed together by charging or discharging one of the batteries
before connecting in parallel.
2
Switch OFF the OVERCURRENT PROTECTION MCB of all batteries.
3
Next, ensure the separate Main Battery Breaker connected to the inverter/charger is OFF.
4
Connect all the batteries in parallel, by connecting them to the main bus bar using the correct
Amphenol 5.7mm Surlok cables (available from RedEarth and already included in all RedEarth
