Might not look like much, but we had a doozy of an electrical conundrum come to us in pieces. It had been previously partially disassembled and some things tested/replaced but the issue of no 12 volt throughout the coach persisted. The system itself was a 54 volt system, but RVs run on 12 volt. So basically power would come into the inverter/charger from shore power, the inverter charger would charge the battery, then would come out of the 54 volt battery and have to be converted back down to 12 volt to safely power the various 12 volt systems in the rv. On top of all that the actual amp hours of the battery itself wasn’t as high as you’d think for a system like that.
We did eventually condemn the battery itself after working with the manufacturer of the system who then quoted us $9500 to essentially rebuild the battery pack. We ended up removing the entirety of that overly complex system (inverter charger, wiring harnesses, battery pack, both converters, and control panels) and installed a more powerful 12 volt inverter charger, 628 amp hour battery pack, and simple control screen. Reprogrammed the solar controller to work with the new system, and viola, functioning 12 volt and a simplified system all with the ability of being controlled by your phone if needed or by the panel in the rv. It ended up costing the customer $3000 less than just the battery itself would have and instead of them waiting weeks and weeks for the back and forth shipping and time in the manufacturers shop they got it back in about two weeks. Plus the components are new and under warranty.
I also got to clean up some rats nest wiring (as best as I could, rv factory wiring is cringeworthy at best), so it was a win win win all the way around.
