Orion Smart DC-DC Charger Settings for Connection to 2018 Ford F250 Upfitter Switches

Summary of Issue:

Not always getting charge to my batteries, when I do, the VictronConnect app doesn't reflect the charging state or battery levels.

Details of Issue:

I have a truck camper on my 2018 Ford F250 with the heavy duty alternator and auxiliary upfitter switches. I've got everything running off of upfitter/AUX switch 1 which is rated for 25amps. Cabling is marine-grade 10/2 all the way to the Orion Smart 20amp DC-DC charge controller. I'm consistently always getting 14.7V input at the Charge Controller, but have different results/scenarios on the output voltage:

  1. I do not get output voltage to my batteries: this is after starting truck with AUX1-switch enabled, or, having truck run for a few minutes before enabling AUX1-switch. This is with Engine Shutdown Detection enabled and Input Voltage Lock-Out enabled.
  2. I get output voltage to my batteries, but app does not reflect charging state and reports that charging is disabled: sometimes I can have AUX1-switch enabled when I start the truck and will very soon after will have output voltage to batteries. Or, after having truck running, I enable AUX1-switch and shortly after have output voltage to batteries. This is with Engine Shutdown Detection disabled and Input Voltage Lockout disabled.
  3. I get output voltage to my batteries, and the app reflects the charging state (bulk, float, etc): I've tried about every combination of settings in the VictronConnect app I can and the times I've seen the app report the charging state have been just about random. The times I've adjusted VictronConnect app settings and it has reported 'bulk' charging state, it does not continue to do so after turning truck off and back on. I've also only been able to get app to relfect 'bulk' charging state while truck has been running (and AUX1-switch enabled) and I've made changes in the charge controller settings, I've yet to see a 'bulk' charging state on startup without changing app settings.

Installation notes:

  1. From upfitter/AUX switch 1 (rated for 25amps), I've run marine-grade 10/2 to the terminal/junction box I installed on camper (so that I can disconnect cabling in the event I remove the camper or sell it). 25' of cabling at most.
  2. From the terminal box, the marine-grade 10/2 runs through the interior of camper to the Orion Smart DC-DC charger input terminals. 25' of cabling at most.
  3. From the Orion Smart DC-DC charger output terminals, marine-grade 10/2 cabling to battery compartment, connecting to 2 Dakota Lithium 54ah batteries connected in parallel. 9' of cabling at most.

Extra:

  • I also have a 200watt 10amp solar panel array (2 panels) with 20amp charge controller connected to batteries.

Your photo shows a 24v input / 12v output model Orion.

Please confirm model, and F250 system voltage.

Well dang of all the things to overlook, that would appear to be the issue. Model I purchased:

Victron Energy Orion-Tr Smart 24/12-Volt 20 amp 240-Watt DC-DC Charger, Isolated (Bluetooth)

Thanks for chiming in
