If I'm using an electric jack or a slide out motor that draws say 40-50 amps, then I would have to get two of these..
I have a
Victron 24->12 voltage reducer on my 24v system. Pot adjustable where I keep it at 12.5vdc. At 25a (and $100) it runs my slides just fine. Victron makes these for 48vdc also.. a little difficult to discern from their website but it's there. I've never concerned myself with efficiency - I'm not sure what that matters.
I was also looking at
this one for my future needs which should suffice.
The largest off-coach power setup I've seen was in Quartzsite a few years ago. Probably 2,000w of panels on tiltable mounts, 16 6v batteries, humongous inverter on the bed of a Class 8 tractor. The guy had no trouble running his air with it.
