4 batteries Victron AGM 12-230 Super cycle
12V210ah @10h rayte
12v230ah @20h rate
MPPT solar charge 250 I 100 - tr
20 solar panels @300w each.
The system worked great from May2019 till current where low voltage battery was becoming a problem even when not on load. Even a 300w load now when low solar yield cuts the battery to 46volts and shuts down. This never happened before. Only occurs when usage is greater than pv yield
Are the batteries the problem?
We have been having load shedding on a regular basis.
