come off the battery
pos to a unswitched bus bar. a short large cable run. wrap it in split loom. here put the inverter
, ACR / echo charger if have, battery
parrellel wire if have (should have) and wire going to house battery switch. run this to battery switch. after the switch you may or may not need another (switched) bus bar depending on loads. may just be single
cable to DC panel. or may have windlass
, winches, or other big switched loads.
all those wires should be fused as they leave the bus. the inverter should have a battery switch too.
from battery neg to to another bus bar for neg. shunt in-between battery and bus bar if battery monitor
battery should only have one cable on each post. (+jumpers if parallel batteries)
