Ok hang on.
The Orion should be connecting the engine room aux batt to the rear batt. (LFP)
I thought you already had a solar controller? If so, no need another device to manage that charge source. Just run it to the LFP.
Besides, in the interest of redundancy, you don't want a single device...
This is correct. Both the Victron and Redarc BCDC go to the batt bank in the rear of my truck.
This ensures the batt bank can be charged through the RedArc when the truck is running.
And the Victron does it's trickle thing when the truck is not running.
When running, and I turn the RedArc on...
Run the winch cables to each batt - My winch + goes to the aux batt, winch - to the crank batt. You still get access to the headroom provided by two batts, but it alleviates the need for the SBI to support that current flow altogether. Can do the same with jumper cables. All the SBI needs...
OK, I see you're hip to what's with it, so I'll just throw out what I've learned. Take what you find useful. 👍
1) Recommend the SBI12 instead of the SBI212. Keep current flow one-way only. There is no use-case to charge the crank batt from the aux batt, even when the crank batt is dead...
Well as it is the 2nd batt - with the SBI relay - is the redundancy.
What is the device connecting the 2nd engine room batt to the LFP? That was the device I was referring to as "Orion device" (bad eyes/screen).
It will. lol
All I'm trying to get at is if the "orion device" only functions...
Just curious, why is the solar panel going to the engine room aux batt and not to the batt supporting all the load? This is unnecessary complexity and makes less efficient use of the fruits of solar regen. And $400 for a 90w panel??
+1 RedArc BCDC for efficiency. But I'm biased.
Are you...
