Overvoltage on AC-out

Hi,

I have got a 120/240V system comprised by 6x Quattro 5kVA 120V units (3x per leg). This system has been working perfectly for a couple of months however for the last few days, when the generator switches OFF the voltage at the output drops for about 30 seconds and we are getting the alarm "#5 Overvoltage on AC-out"

I have checked the voltages on the input and realised the voltage on L1 was quite high 130V approx. I though that was the problem, however I have fine tuned the generator voltage to be closer to 120V and still having the same issue. According with the Victron documentation, this Error 5 could be related to a wiring issue on one of the slaves but I have checked that and everything seems fine.

Thanks in advance.

btw we're in contact through email about this issue, and will post here when we find the cause (AC disconnect voltage, generator, PV, ??)
