Is our wind and solar confusing our BMV602?

We recently replaced our 1000 ah bank like for like and the other day I put the kettle on soc was 94 and the low battery light came on.

2 nights ago SOC was 60 and I assumed the genny would run in the night we had high winds and in the morning we were on 100 SOC the genny hadnt run and the battery voltage was on 23.6

Is our 4kw via 2 x blue solar and our 1kw Airdolphin confusing the BMV 602 if so how do we stop this?

Any advice would be seriously appreciated also we are concerned for our batteries now,

many thanks

Claire

The BMV would not care about the charging source or the loads. It only measures curent going in or out.
Is the wiring of the shunt exactly as it should be, is it the same as it was before the batteries were swapped out?
Secondly, it seems like the BMV has not synchronied properly.
Please check that the settings are correct especially the battery capacity. Some settings need to be reset when connecting the battery again.
