Multiplus II disconnect from grid
Multiplus with grid connection on AC-IN, Fronius on AC-OUT and Pylontech bateries and Cerbo, all with latest firmware, with ESS assistant installed, Multi disconnect from utility grid, it you manually reconnected the grid, the system remain connected to grid for some minutes and disconnect again and every time.
Gird Frec in is 50.1Hz Voltage around 240 (inside Spain regulation limits)
Any idea or solution?
You seem to have a problem with your grid.
RoCoF means: Rate of Change of Frequency.

while it remains connected in mk3 alwais indicate 50.1Hz, no variation in VRM we can see:
so, despite the down in freq while disconnect it's look estable at 50.1, do you thought it's a Grid problem?? if we bypass the multi and reconnect grid to house, all run's smothly
