High voltage alarm

Hi all
Randomly today I have received endless high voltage alarms, the maximum was 60.9 volts and the longest was 12 seconds but it looks like this happened whilst my son was using his oven over a 2 hour period although it's been used before without issue, the batteries were in absorption phase. I have noticed that the throttling of the AC inverter is a bit delayed and I think this may have played a part in the alarms.
Shunt high voltage alarm is set at 60.5 volts
I am starting to regret going up the AC inverter route.
Would altering the assistant HZ settings make things react a little quicker ?
Setup is
930ah (C5 rating) IPzS 48v battery setup, using flooded tubular plate profile in charger
Victron multiplus 2 48/8000/110 inverter
fronius AC 8.2-1 inverter on AC1 out
Smartshunt 500
Cerbo GX

AC coupled and switching large loads when bat is full ... mhhh power has to go somewhere... at least for a bit...

Not familiar with your set up but limiting max charge voltage and maybe lowering overall bat voltage by .1 or .2 volt could help absorb this issue by giving the bat a litle more "headroom" so the inverter can power down....
