POWER PERFORMANCE PASSION
SP PRO Interactive Inverter Charger
Operation of the SP PRO
The SP PRO reads all the data out of the batteries and automatically adjusts the battery current to suit.
This means the operation is a little different than with other battery banks.
When connected to the grid, the operation of the SP PRO is as follows:
1. When the SP PRO is charging the charge current will be limited to the “Charge Current Limit” as
displayed in Battery Management (see diagram above) and the charge voltage limited to “Charge
Voltage Limit”.
2. When the SP PRO is supporting the load, the current taken from the battery bank will not exceed
the “Discharge Current Limit”. The SP PRO will adjust its maximum support power to ensure the
discharge current is not exceeded.
When the grid fails, the operation of the SP PRO in standalone mode is:
1. When the SP PRO is charging from the PV, the charge current will be limited to the “Charge
Current Limit” as displayed in Battery Management (see diagram above) and the charge voltage
limited to “Charge Voltage Limit”.
2. When the SP PRO is supporting the load, but the current drawn from the battery exceeds the
“Discharge Current Limit”, the SP PRO will go into current limit and reduce its output voltage. If
the load so high that the AC voltage drops below 200V for 10 seconds, the SP PRO will shut
down as the battery can no longer support the load. The customer then needs to reduce the load
so that when the SP PRO retries, it can continue to provide backup power.
