IPS Test (for Italy CEI0-21 Grid Code only)

Prerequisites

You have logged in to the app as installer. The initial password is 00000a. Use the initial password upon first power-on and change it immediately after login. To ensure account security, change the password periodically and keep the new password in mind. Not changing the initial password may cause password disclosure. A password left unchanged for a long period of time may be stolen or cracked. If a password is lost, devices cannot be accessed. In these cases, the user is liable for any loss caused to the PV plant.

Context

The Italy CEI0-21 grid code requires an IPS test for the SUN2000. During the IPS test process, the SUN2000 consecutively tests the protection thresholds and time for 10-min overvoltage, level 1 overvoltage, level 1 undervoltage, level 1 overfrequency, and level 1 underfrequency. The SUN2000 shuts down after the IPS test starts, and it restarts after the IPS test is successful.

Procedure

1. On the Home screen, choose Device maintenance > IPS test to access the IPS test screen.
   Figure F-1 IPS test
   

2. Choose to start the S1 or S2 check as required. The default check type is S2. To start the S2 check, you need to set External Signal or Local Command.
   Table F-1 IPS test type description

   IPS Test Type	Description	External Signal Setting	Local Command Setting
   S1	The level 1 overfrequency protection threshold is 50.5 Hz and the level 1 underfrequency protection threshold is 49.5 Hz.
   S2	The level 1 overfrequency protection threshold is 51.5 Hz and the level 1 underfrequency protection threshold is 47.5 Hz.
   S2 (default)	The level 1 overfrequency protection threshold is 51.5 Hz and the level 1 underfrequency protection threshold is 47.5 Hz.
   S2	The level 1 overfrequency protection threshold is 51.5 Hz and the level 1 underfrequency protection threshold is 47.5 Hz.

3. Tap Start to start the IPS test. After the IPS test is complete, IPS State is displayed as IPS state success. Tap Reports in the upper right corner of the IPS test screen to view IPS Self-Check Report.
