Hello
For some reason my inverter a multiplus II 48/8000kva make some loud clicking sounds randomly , even when the battery level above ESS.
From what i ve seen on cloudy days it clicks more often but the annoing part is when it clicks at 2 am in the morning…
Probably u will say its normal sound when it self testing at startup, but this one does like that randomly at night time or cloudy day time .
It is normal that it checks the function of both mains relays before switching back to mains operation.
However, you need to find out why its rejecting the mains in the first place. Check the mains voltage and frequency, one of them is either too high or too low for your gridcode.
Is there a log where i can check what happened?
use the “advanced” menu and check the corresponding graphs.
Both voltage and frequency drops if victron measurments are ok but i doubt it .
