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?
