Victron Multiplus 1600 and 4 x Superpack 100Ah - Design sanity check plse

This is a design for a solution that will NOT be integrated in a VAN power system (read alternator) and the 4 x Victron 100Ah superpacks were chosen because of space restrictions and specific desire not to have additional BMS equipment. All main loads are 12V e.g. lights, fridge, boiler etc and will be connected via a fuse/switch panel and the only 230V requirement is for a kettle/hairdryer and coffee grinder ;) and to charge the batteries from shore when required.

My question. Does it look right and how best can I protect the Superpacks (which will be installed under the bed in the van) from charging damage at low temperatures when passing through the Nordics?

The negative output of the MPPTs is on the wrong side of the shunt.
You have to connect them to the same side as the Multi/DC-loads.
