6.9 Self-test (For Italy)
Italian Standard CEI0-21 requires a self-test function for all inverter that connected to utility grid. During
the self-testing time, inverter will check the reaction time for over frequency, under frequency, overvoltage
and undervoltage. This self-test is to ensure the inverter is able to disconnect from grid when required. If
the self-test fails, the inverter will not able to feed into the grid.
The steps of running Self-test are as followed:
Step 1: Connect a communication module (Wi-Fi/ 4G/Ethernet) with inverter (connection procedure can
refer to eSolar Module Quick Installation Manual)
Step 2: Select Italy for Country and choose your corresponding Grid Code from Initial Setting.
Step 3: You can choose self-test item required. Individual self-test time is approx. 5 minutes. All self-test
time is approx. 40 minutes. After the self-test is completed, you can save the test report. If self-test is
failed, please contact with SAJ or your inverter supplier.
