Procedure:
1. Switch off the Sunny Island and open the BatFuse load-break
switch quickly.
2. Short-circuit the measuring cable at the battery current sensor.
Connect the BatCur– and BatCur+ measuring conductors to the
connection for BatCur+.
3. Close the BatFuse load-break switch quickly and switch the
Sunny Island on.
4. Switch to installer mode on the Sunny Remote Control (see Sunny Island operating manual).
5. Select the parameter 225.01 BatCurSnsTyp and set to the type of the battery current sensor used.
6. For a 60 mV model, select the parameter 225.02 BatCurGain60 and set it according to the gain factor of the
battery current sensor.
7. For a 50 mV model, select the parameter 225.03 BatCurGain50 and set it according to the gain factor of the
battery current sensor.
8. Select the parameter 225.04 BatCurAutoCal and set to Start.
☑ The Sunny Island starts the adjustment.
9. After ten seconds, select the parameter 120.06 TotBatCur and read off the value.
☑ The parameter value is between 0 A and 1 A.
✖ The parameter value is not between 0 A and 1 A.
The measuring cables are not correctly connected or not short-circuited.
• Check whether the measuring cables are correctly connected and whether they are short-circuited.
