I will soon be installing a 24v lifepo4 200Ah bank and MPP LV2424 in our travel trailer. To replace the 12v lead acid batteries on the tongue, I plan on wiring a 24-12v buck converter into the bus bars that the lead acid batteries are currently wired into (located beneath a coroplast panel under the trailer behind the tongue). I’m a little confused on what amp size buck converter I’ll need and hoping someone can help based on this picture of the trailer’s DC fuse panel? I will remove the trailer’s current AC-DC charger to avoid sending power back to the buck converter.
I’m also attaching the wiring diagram for the project. My initial plan was to wire the buck converter directly into the DC fuse panel, but after looking inside the coroplast panel mentioned above with the battery bus bars, I think it’s better to connect the buck converter to those bus bars. It looks like the trailer’s break away system and other mystery wires are tied into those bus bars, and I don’t want to cut those out by wiring the buck converter directly to the fuse panel. I’m adding my thought process on my recent change of plans in case I’m missing something and someone can set me straight. Also noting it in case the trailer’s break away system and those mystery wires need to be factored into the equation when choosing the correct amp size for the buck converter. Thanks in advance!
