I am planning to install a MultiPlus 3 KW / 24 V AC inverter/charger in my expedition motor home (RV).
The inverter/charger is unfortunately 3.6 m away from the batteries and from the Central Negaive Busbar. Routing the 50 mm2 wires is a bit difficult due to the confined space.
The original Victron wiring diagram shows independent cables for the chassis ground and for the battery negative connection, but both lead to the same central negative busbar.
What is wrong with bringing together (connecting) the cables for ground-case and for battery-minus directly after Multiplus and thus saving a long cable to the central negative busbar, which would simplify the cable routing considerably in my case?
