I've look at some posts like:
But I'm not sure if my problem is like the ones above.
The problem: Now, everytime I connect to the grid, in a few minutes it will turn off my tiny-house electricity. And then it may come up later.
I'm connected to a poor grid, long cable.
I don't have VEConfigure so I can't e.g. disable LOM or anything like that.
All I wanted is: be connected to the grid, even if it's poor (I try to set limits to import or export to the grid), and when the grid fails, I want the victron to keep running my electricity from the PV or battery like if nothing had happened, but no, it's disrupting, shutting down everything. It should just disarm the relay and not shutdown my house.
