5.3. Self Test for Italy
The Self Test function is only valid for Italy. It tests the inverters’ grid monitoring function of
voltage and frequency. The inverter carries out four test sequences, which together takes
approximately 2 minutes.
The self-test changes the trip values for the voltage and frequency to the current grid levels to
determine:
• Whether the threshold equals the actual measured grid values.
• Whether the inverter is triggered to disconnect from the grid by these limits.
Start
The Self Test can only be activated when:
• The installation procedure is executed
• The country configuration is set to Italy
• The inverter is in Running/Derating Mode (i.e. sufficient irradiation).
Select: Commands > Inverter Commands > Self Test
Left or Right – Select START or CANCEL
Enter – Confirm
The test needs some seconds to start. The test can fail if the irradiation is
insufficient, as the inverter is unable to feed
power to the grid. Restart the test later.
