Backup Power Restart Attempts Exceeded

Hva betyr 1177 ?

Service message 1177 is triggered when the inverter has reached its maximum configured number of automated restart attempts in backup power mode. This indicates that the system failed to re-establish backup power operation after multiple shutdowns.

• Repeated failures to restart backup power mode due to persistent issues.
• The configured 'Backup power restart attempts' limit has been met.
• Underlying issues preventing stable backup power operation (e.g., undervoltage, overvoltage, short circuit, etc.).

1. 1

   Manually acknowledge service message 1177 on the inverter's user interface to clear the fault.

2. 2

   Check the 'Backup power restart attempts' parameter (1-10) to understand the configured limit.

3. 3

   Investigate other potential backup power related faults such as 'Backup power undervoltage protection time U<', 'Backup power surge protec- tion time U>', or 'Backup power short circuit switch-off time' that might be causing repeated shutdowns.
