Hello,
ESS 3x Multiplus-II 48/3000 grid parallel with Pylonthech, Cerbo, RS 450/100, EM24
no AC-Out connected, no Grid connected solar inverter.
not the first system we have installed.
We have more ore less the same system running perfectly for a few month.
The AC-IN gets disconnected from grid after a minute for a few minutes for no reason over and over again.
everything ist brand new and FW is up to date....
Any ideas to solve the problem?
Connect with the mk3, under grid tab, check the NS protection log. It should store the last few outage events and the cause.
You could also use the VE bus monitor in real time which will show if there are grid issues.
Is there a smart meter? Some will disconnect if they see power being pushed.
the german grid is pretty stable, but i will take a look to the voltage as you mentioned.
Problem solved, bad neutral connection.
