The inverter has dual DC terminal studs. I will only need one set for battery input. Can I use the second set to connect to my MPPT charger, for wiring convenience? This would keep my 6AWG wire from MPPT much shorter. DC input is sized 2/0AWG and has fused disconnect in circuit. MPPT output has circuit breaker protection.
Intention of the system is to have MPPT charging available at all times, with the inverter switched to off whenever the cabin is not in use. No grid connections.
BMV712 shunt/temp sensor will be connected close to battery terminals.
The DC terminals are not intended as a busbar.
For that rated inverter you are at the limit of what one battery cable is designed for, which is why there are 2 terminals.
If it is physically in the off state it should not have an idle load, other devices like a Cerbo, or built in GX, would still draw power.
If you went with a best-practice busbar approach, you could physically isolate the Multi.
It is more work but worth the effort.
As is running dual battery cables.
With these installs, more is more and the easier way can sneak back to haunt you
