Hello. I'm using a Multiplus-2 48/5000/70-50 running 507 firmware and noticed that it sometimes disconnects itself from the grid and I can see in VRM that it was doing the power assist even though I have it turned off and set input current limit to 32 A (230 V) which is way more than it was necessary to run a 2 kW load that you can see on the screenshots.
So the main question is why does the power assist happen when it is disabled in settings?
Thank you.
You may have a high impedence connection to grid, so the easier source is the battery. The disconnect from grid is a symptom of that.
That certainly can be the case. Some time ago I asked a question on this forum regarding random disconnects from the grid that I still experience at this thread
Sadly, as far as I can tell, there are no diagnostic logs in MP-2 apart from NS protection log that can tell why the disconnect happened.
Is there a way to read a resistance of grid connection measured by MP-2?
Changed resistance to impedence. The more correct term.
No I don't think the inverter or system does records/reports it anywhere. I have not really looked to be honest.
You can sometimes tell a connection problem by the way the voltage and frequency fluctuate
If you pull a high amp draw from there does the voltage sag? If it does the connection impedance is high.
