The Italy CEI0-21 grid code requires an IPS check for the SUN2000. During the self-check, the SUN2000 checks the protection threshold and protection time of the maximum voltage over 10 min (59.S1), maximum overvoltage (59.S2), minimum undervoltage (27.S1), minimum undervoltage (27.S2), maximum overfrequency (81.S1), maximum overfrequency (81.S2), minimum underfrequency (81.S), and minimum underfrequency (81.S2
Procedure
Step 1: Login as Installer and on the home screen, choose Maintenance > IPS test to access the IPS test screen.
Step 2: Tap Start to start an IPS test. The SUN2000 detects maximum voltage over 10 min (59.S1), maximum overvoltage (59.S2), minimum undervoltage (27.S1), minimum undervoltage (27.S2), maximum overfrequency (81.S1), maximum overfrequency (81.S2), and minimum underfrequency (81.S1), and minimum underfrequency (81.S2).
