Assistant Explanation

What exactly does the following Assistant options mean?

I have an unstable grid where my Quattro loses frequency sync. I am looking for an Assistant option to select that triggers on Grid Sync Loss (Grid doesn't fail, frequency drops low).

Hi @Ingo

Bulk protection: an option that stops charging when bulk phase takes longer than 10 hours

General system failure: when there is an alarm.


what you can use is:

Thanks @Daniël Boekel (Victron Energy Staff)

I am looking for an option I can select when grid frequency drops below 47.5Hz. My Relay assistant doesn't work when the grid frequency drops low and that causes ACOut2 NOT to disengage and kills my batteries. I will test the 'Not Charging' option.

Hi @Ingo, I don't know of such an assistant, so that's why I suggested to use the option listed above. that will effectively do the same: activate when AC-input is disconnected.
