Just another thing to consider (energy density) in the plan for power independence while boondocking. Safe, and Hoppy Travels from The Boondocking Brewer™!

Can you please provide the URL reference for the size of the batteries you are talking about. I have a hard time believing your claim of 12 in the same space as four GC batteries. I have never seen a 100 AHr lithium battery that was much different in size than a standard 6 volt GC battery.

But based on what you wrote, how would I be able to use household electricity without an inverter? My understanding is that the inverter is changing 12v from the batteries to 120v for household appliances.

Maybe I could use the MPPT, but I thought those just wrangle the irregular output from the panels and convert it to 12v to charge the batteries.

Sorry for getting back to you late. Out in an area with non-to-almost-non data service.

1: LED lights in a camper are almost all 12v lights. Change the bulbs to LED bulbs, there is a large selection of automotive led bulbs. Even the small florescent lights are 12v and there are conversion kits.

2: phones: Most phones charge via usb chargers. There are 12v USB charger ports you can install in your camper. Run it right off Just about any 12V circuit.

3: computer: I dont have much of a solution. I run my laptop until the battery is low and then plug in the inverter.

I have adapters for my Macbook that plug straight into a standard 12 volt outlet. No need for 120 volt to power a standard adapter. Makes life simple. No inverter in the 5th wheeler. We do have an inverter in the MH.
