IN0016 Revision 12 Part # 004573 – 22 of 22
SP PRO Three Phase
Installation Notes
POWER PERFORMANCE PASSION
11. Charger Override – Override Charge Limit is set to 5kW. This means that the charging
will be limited during Charger Override to 5kW per phase giving a total charging limit of
15kW for the battery.
12. Start SoC and Stop SoC are set to 55% and 70% respectively. When the SoC drops to
55% and before it rises back to 70% the Charger Override limits apply (points 10,11)
Synchronising SoC between inverters.
Each of the three inverters track the battery SoC and use this for the generator control and the
Solar Hybrid Schedule.
When the inverters are first powered up the SoC is set to 85%. If this SoC needs to the
changed (Service Settings) then the same value must be set in all three SP PROs.
When the Battery Charger reaches Float then all three inverters will synchronise by resetting to
100% SoC.
Operation
Once the SP PRO units are installed and configured correctly, the system is controlled by the L1
phase. Changing the system operational mode (from
Idle
mode to
Run
mode, or back to
Idle
)
is done via the
On
button on the L1 phase only. L2 and L3 phases will follow the operational
mode of L1 automatically. The
On
buttons on L2 and L3 phases are disabled.
As each inverter is tracking the battery SoC the battery indicators on the front of L1, L2 and L3
should display the same number of bars.
Note: It is normal for Phase Sync Error to occur in IDLE and if all DC Connections are NOT
CLOSED
