Multiplus going into Storage mode instead of Bulk

Hi there.

I have an annoying issues with my Multiplus.

On my boat, I have solar and shore power (230v) available to charge the batteries. Sometimes when the solar has been charging the batteries in bulk, the batteries are around 13.1-13.6v. The multiplus is turned off when the solar is charging. Then when I turn on shore power and the multiplus, instead of continuing to charge in bulk, the Mutiplus goes into storage mode.

The only way to get the multiplus into bulk is to force a system reset. Is there anyway I can fix this?

Thanks.

The lithium batteries setting disables "storage charge "

There are probably better solutions..

A couple of examples where the Multiplus is in the wrong state.

Unfortunately not. It tends to only happen when the batteries are mostly charged, so must be a voltage control behaviour. When it happens, I just hit reset/redetect on VenusOS
