Lead-acid batteries: Adjust the battery management to the battery
Qualified person
You will find further information on battery management and the charging processes of the Sunny Island for lead-acid batteries in the technical information "Battery Management" at www.SMA-Solar.com.
The basic procedure for changing operating parameters is explained in another section ( > Changing Operating Parameters).
Procedure:
- Select Battery > Charge.
- Set the parameter Maximum charging current to the maximum battery charging current recommended by the battery manufacturer.
- Set the parameters for boost charge. First set the parameter Battery boost charge time to the boost charge absorption time recommended by the battery manufacturer.
- Set the parameter Cell charge nominal voltage for boost charge to the cell voltage setpoint recommended by the battery manufacturer for boost charge.
- The parameters for boost charge are set.
- Set the parameters for full charge. First set the parameter Battery full charge time to the full charge absorption time recommended by the battery manufacturer.
- Set the parameter Cycle time full charge to the full charge cycle time recommended by the battery manufacturer.
- Set the parameter Cell charge nominal voltage for full charge to the cell voltage setpoint recommended by the battery manufacturer for full charge.
- The parameters for full charge are set.
- Set the parameters for equalization charge. First set the parameter Battery equalization charge time to the equalization charge absorption time recommended by the battery manufacturer.
- Set the parameter Cycle time equalization charge to the equalization charge cycle time recommended by the battery manufacturer.
- Set the parameter Cell charge nominal voltage for equalization charge to the cell voltage setpoint recommended by the battery manufacturer for equalization charge.
- The parameters for equalization charge are set.
