51,4Hz on ACin, 52,9Hz on ACout Multplus-II is not dropping to Island Mode - Fronius can not StartUP no Production

[sega]

Hello Victron Stuff,

we have again some Grid Service in Austria and our Energy Provider pushed the Frequenz to 51.4Hz. The 3Phase System is not dropping the GRID. So the Fronius PV Inverter is still at StartUP and not producing any Power (Fronius is in MG50). We had this Problem in serval Installation’s this year!

Is this a Software Problem? Do you have any Idea how to solve this Problem, because now the System is draining the Battery normal the ESS Level is set to 10% @guystewart @mpvader
