SP PRO Three Phase
Installation Notes
POWER PERFORMANCE PASSION
Zero all current shunts
Put all units into Idle Mode – Hold ON button for 2 seconds on L1 inverter ONLY – light on L1
will flash “orange” (green/red both flashing on at the same time).
Note: ON button on L2 and L3 are disabled in a three phase system.
For L1, L2 and L3 go into Service Settings >Shunts and press Zero Shunt 1
This will zero all phases in system.
Note: All phases MUST be in IDLE mode during the zero current shunts procedure.
Test shunt 1
This test is to check shunt polarity.
With AC Sources disconnected, Apply load to any phase.
Check Data View > Now > DC > Battery Current, this should now be negative indicating that
the battery is delivering power.
Repeat for L2 and L3 phases checking that the polarity and value of the Battery current is the
same as L1.
SoC Control
The SoC is managed by all three phases. SoC needs to be enabled on L1, L2 and L3
Battery Capacity
Each SP PRO needs to have the Battery Capacity setting configured to the full amp hour
capacity of the battery bank.
Max. Charge Current
The Max Charge Current setting in L1, L2 & L3 phases must each be
configured to one third of the maximum charge current required by the
battery bank. For example if the maximum charge current is 150A then
set the Max Charge Current setting to 50A in L1, L2 and L3.
Battery Charger Voltage settings and Temperature Compensation
All of the battery charger voltages, time and temperature compensation settings should be the
same on all three phases. All three phases must have their battery temperature sensor
connected. All 3 temperature sensors must be bonded to the same location on the battery
bank.
