I just watched the latest video from "Gone With the Wynns" and they toured a Lippert factory in London that makes parts for boats. Deep into the video they had a very good discussion with the Electrical Engineer about 48 volts versus 12 volts and the advantages of transitioning to the higher voltage.
Boats use electric motors just like we do in our RVs and the same advantages exist for the RVer as they do for the boats. It seems like the boat world is making the transition to 48 volts and Lippert is deeply involved in the transition. Since Lippert is a huge supplier of parts and systems for the RV world, it is not a stretch to think the transition to 48v will happen to Rvs, probably sooner than even I would have thought.
Here is the link to a very interesting (and short) discussion on the advantages of 48 volt vs 12 volt electrical systems:

Surprise !!!!
48 volts is already here !!!!
Recently, Sandy Munro, of Munro and Associates was given an opportunity to preview one of 12 prototype Winnebago Class B, Fully Electric, Camper Van. During the discussion it was mentioned that the van had 3 voltages operating inside the camper, one of those voltages was 48 volts! The Air Conditioning system operates on 48 volts in this new camper.
Just think how nice it would to be able to operate your Air Conditioner directly from your 48 volt DC battery bank and not even need an Inverter to run the A/C.
Here is a time stamped clip of where they begin to discuss the 48 volt system in the Camper Van:

I recommend you back the video up to watch the whole overview of this Class B, Fully Electric EV.David and Peggy

Friends of ours, Tom and Stacie of RV Texas Y'all, first they started by eliminating the propane system. Installed an extreme solar, lithium and 48V system on their Class A designed and installed by Master Tech in Elkhart. They have a video about it up on You Tube. 12 solar panels, huge battery bank, and a bunch of other stuff I don't understand, Master Tech also installed a 48V alternator on the engine. They have some kind of charging and monitoring system that keeps all the batteries evenly charged and balanced. I think Tom said for the initial test they ran off grid, even running both AC units of just the batteries for over 34 hours and only got down to I think he said 30%. The 48 V system charges much faster and with their options of battery charging - solar, their on board generator or the Class A's engine, they don't need external power.
i guess Master Tech is installing a lot of these systems for Class A's.Steve & Tami Cass - Escapee's, FMCA Members, Texas Fulltimers Since July 2020

Is it a 48v system or a 48v battery bank? 48v battery banks are quite common on larger rigs. Basically, the storage capacity is stored at 48v, but there are no 48v load devices drawing off the batteries. All appliances would still be 12v or 120v (or even 240v since split systems are quite the rage right now). I would go 48v if Victron offered the 2x120v MPII in a 48v configuration.

I really don't know, he talks about a lot of things I know nothing about. Here is their video, you can probably make more sense out of it than I can. It's all confusing to me.
