Victron Upgrade Series Part 1: Orion XS 50A DC-DC Charger Install

This upgrade will be completed in multiple phases. Over time, all, or at least most, of the coach battery system will be converted to Victron components, excluding the lithium batteries themselves. I am starting with the DC-DC charger. The wiring schematics remain the same. Check the SFK lithium battery installation on this link (click here).


The original 40-amp Renogy DC-DC charger has been replaced with a Victron Orion XS 50-amp DC-DC charger. For reference, you can view the original 40-amp Renogy DC-DC charger installation at this link (click here). Here’s how a changeover switch can be used to activate either the ACR or the DC-DC charger, ensuring only one charger is active at a time (click here)


The DC-DC charger will remain in the same location, which required fabricating a new mounting system for the Orion. This time, the mount is designed in two pieces. The baseplate is secured to the firewall using three existing OEM bolt studs. A separate L-bracket holds the Orion and bolts to the baseplate, allowing for easy removal if needed.

  • Alternatives that are much safer and often cheaper in the long run.

What I will not provide:

  • Exact wiring diagrams or step-by-step instructions for modifying MOTs or wiring mains terminals in a way that could cause electrocution.

  • Specific measurements, voltages, or instructions to bypass safety features on appliances.
