I purchased an Apex 300 with 2 extra battery packs to use in my 2006 31’ motorhome. I’ve located the automatic transfer switch that currently takes my shore power and generator inputs and was originally going to just replace the generator feed with a 30 amp pigtail plugged into the Apex. My generator needs repair and won’t run for long… but that’s a fixable thing.
While (over)thinking the setup I realized that instead of replacing the generator, I could - in theory - put the Bluetti in place of the shore power and then put a standard plug outlet on the shore power line in that would be plugged in to the 15 amp charging input. In that scenario the rig would always be “on” with the Bluetti and then the packs would charge off the shore line.
Placement for this is super easy, the storage space under the bed is also where the house wiring and built-in automatic transfer switch live. There is room for the boxes under the bed and there’s already passive ventilation in place.
The two things that jumped to mind from that were:
- How do I charge the Bluetti if I’m running on Generator power? Initial thought is to have a second plug handy
- Is it possible that the draw from the motorhome would “out run” the input charge? Potentially but as with any electrical line the 30A is a “Max use” not constant and regular draw even with the Air Con running (not startup) is in the 15 amp rage.
What are thoughts on running the wiring this way?
