Hello everyone, I’m new here so bear with me. I have a truck camper that has only one lead acid battery in it. The camper has a 120v and 12v panel setup. The current charger won’t work with Lithium charging. So I’m basically starting from scratch.
I’m trying to find a schematic somewhere that will show me all of the devices I would need to accomplish the following:
I would like a 24v system even though I only have 12v devices
I would like to be able to charge the batteries with solar charge, plug in 120v charge and dc to dc charge from my 12v truck system
The biggest draw in my camper will be my 3 way fridge which I want to use 12v to power it will driving or camping.
The Maxxair fan will also run constantly while driving and camping.
Occasionally running the microwave off the inverter to heat something up.
We don’t plan on running the AC at all off of the batteries.
We have propane on board for cooking, heat, hot water
I’m assuming 2 batteries should be enough? What size should they be?
Should I just do a 12v system instead and keep it simpler?
Thanks in advance and can’t wait to get started

Hi Steve,
This forum is for asking specific technical questions, not providing design details for a new installation. That’s mentioned in the rules and I think mentioned at time of account creation. I’m sorry to sound like a negative jerk in responding to your first question. But, I can offer some advice for you. You can find a list of Victron dealers and installers here: https://www.victronenergy.com/where-to-buy
Enter your location and look for someone close to you. If you don’t have anyone close, or you just don’t want to work with them, then find an installer you’re willing to drive to. A good Victron dealer will design a system that meets your wants and budget (they don’t always align). If you want to do the installation yourself, they can still design a system and provide you with a wiring diagram so you can be successful.
