G'day
Multiplus II 48/5000
ESS
Pylontech 3000x8
4.5kw ac coupled pv on ac out
Now summer has arrived,{Australia} I'm seeing overvoltage alarms from the pylontech, and the dc bus voltage seems to be hitting 56v.
Fully charged, on grid and feeding in.
The ac grid is on the higher side, at about 245v but within spec.
This has happened 3 times now, while I am away so house is relatively low load.
A) what could be causing this?
B) what if anything can I do remotely?
C) what can I do on my system to prevent?
If I was home I could possibly increase load, or shut off solar, but neither are ideal as I'm not always at home, and shutting off solar may cost me..
Thanks
