I'm installing a new Victron system, 2x lfp batteries, 24/12 dc-dc charger, a 12/30 mppt solar controller, and a ip65 Smart Shunt. My query is, is ok to use different chassis earth/return points along the chassis for all load and chargers or, should they all have a common 'tie' point on the chassis to the load side of the shunt? .....cheers Mike
