What if your camper could charge your TRUCK? ⚡
Our Victron Orion XS normally takes power from the truck and charges the camper batteries. But I wired in a motor-reversing switch that lets me physically reverse the current path.
Flip one switch and instead of:
Truck → Camper
we can do:
Camper → Truck
It's handy if the truck batteries get run down, and I also use it when running our high-draw onboard air compressors.
You still need to change the Orion XS settings for the correct voltage and operating mode, so this isn't quite true automatic bidirectional charging—but it's been a simple workaround that works really well.
