Trouble Reaching Bus Bar
When we installed our system, we were able to get a ring connector lug on the positive wire from the solar controller and bolt it to the battery side of the use/store relay. We donít have a buss bar near it, and the convertor and fuse/breaker box is mounted under the aft dinette seat. Too far to run there. Our MPPT controller is mounted just aft of the closet on the streetside and it made sense to run a heavy cable to the center under the bed forward wall. You could certainly run a cable as you suggested with a nice fuse in the line to protect the wiring from a battery short to ground....
