NOTE
■ The Auto Test can be activated only if there is suf cient irradiance and the inverter
is connected to the mains and is in feed mode.
■ If a fault occurs during the tests or the irradiance is too low the Auto Test is aborted
and the message “Auto Test aborted” appears in the display together with an as-
sociated error message.
Procedure
1. Wait until the inverter has connected to the grid.
2. Select the “Auto Test” menu item in the Main menu.
3. Start the self-test press the
button to con rm. The Auto Test now runs auto-
matically:
Maximum voltage
– The set voltage monitoring threshold Vac max is displayed.
– The threshold value is decremented linearly until it reaches the current mains volt-
age value and mains monitoring is triggered.
– The trigger value, the delay time, the current value and the default voltage monitor-
ing value (Vac max) are displayed.
Minimum voltage
– The set voltage monitoring threshold Vac min is displayed.
– The threshold value is incremented linearly until it reaches the current mains volt-
age value and mains monitoring is triggered.
– The trigger value, the delay time, the current value and the default voltage monitor-
ing value (Vac min) are displayed.
Maximum average value of the mains voltage
– The set voltage monitoring threshold Vac 10 min max is displayed.
– The threshold value is incremented linearly until it reaches the current mains volt-
age value and grid monitoring is triggered.
– The trigger value, the delay time, the current value and the default voltage monitor-
ing value (Vac 10 min max) are displayed.
Maximum frequency (first limit)
– The set frequency monitoring threshold f max 1 is displayed.
– The threshold value is decremented linearly until it reaches the current mains fre-
quency value and mains monitoring is triggered.
– The trigger value, the delay time, the current value and the default frequency moni-
