I have a Multiplus 12V/2000/80 on 3 12V/200 Ah Lifepo batteries to power my sailing boat. Additionally I have 2 solar charge control Victron 100/30 and Cerbo. The most peculiar thing that happens is, that once the battery status falls below around 70%, the solar panels are cut out! When I need them most, they are dropped. Now, that is clearly quite the opposite of the whole idea. The installer claims it is the BMS that does this but I doubt that. Last time this happened I had to start the engine to bring the battery charge status to above 70% - give or take - in order to get the solar panels to feed again. Bug or installation flaw?
