6.1.4 Battery Type
In stand-alone operation, the battery type and the charging voltage must be set. The battery type
and charging voltage are set using the B1, B2, B3 and B4 DIL switches. When performing these
settings, observe all the specifications of the battery manufacturer.
The possible settings for the charging voltage/cells can be found in the following tables.
6.2 Commissioning
Check the following requirements before commissioning:
•
properly designed fuses
•
full connection of the DC cables (PV strings and batteries)
•
connected battery temperature sensor
(only in stand-alone operation or during operation with a Sunny Island 3324/4248)
•
configured DIL switch
Commissioning Procedure
1.
Check the polarity of the battery and the PV generator.
2.
Close the charge controller. Fasten the lid to the housing using four screws.
3.
Connect the cables leading from the charge controller to the battery on the battery.
4.
Switch on the line circuit breaker and the disconnection unit.
5.
The LED changes its color from red to green. The green LED indicates that the device is
operating. If this is the case, commissioning was completed successfully.
If the PV voltage drops and falls below the battery voltage, the LED changes from green to
orange. If the PV voltage exceeds the battery voltage, the device starts back up and the LED
changes from orange to green.
