I am wiring up my Victron Orion 12 to 24 DC to DC charger to charge my solar battery bank. I see where you can add a switch to turn the unit on or off but why would I need an on and off switch if the unit can sense when the vehicle is running? When I turn the vehicle off the charger shuts off, so why the switch?
I prefer to use solar only for charging, so I can learn what to expect from it. However, if the solar stops working, I can turn on dc-dc with the switch.
People like to have options *shrug*
There are also multiple uses for the remote jumper besides just adding a physical switch, as outlined in the user manual. Ignition-on triggered charging rather than automatic voltage-triggered charging, BMS control, etc etc.
