This DIY camper solar wiring diagram and parts list is a high powered system capable of delivering up to 6000w of power through 120V or 240V split phase (3000w through each L1 & L2. This diagram is also capable of charging via solar at a rate of up to 2900w per charge controller added.
This diagram features:
- Dual 3000W Inverter Charger
- 800+ Amp Hours (@12V) of Battery Storage Capacity in a 24V Battery Bank
- Virtually unlimited Solar Array Capacity
- Alternator Charging (100A)
- Shore Power Charging/Passthrough
**Disclaimer & Managing expectations** Setting up dual inverters is NOT a ‘beginner friendly’ task. It DOES require some programming via computer to sync the dual inverters so they will deliver 240V split phase properly (2x 120V legs, 180 degrees out of phase). If you don’t understand the concept of the phrase you just read (and are unwilling to learn this concept)… this setup may be a bit too advanced. That said… here are some good resources that talk about some of the nuances of dual inverter setups:

DIY Camper Solar Parts – Shopping List
The list below is a consolidated parts list for this entire system (Minus the solar charging leg, as that varies greatly from system to system. If you need help designing an appropriate solar array for this system, consider joining the EXPLORIST.life private group: https://www.community.explorist.life ).
For the ‘Quantities’ in the below shopping list, each singular component is listed a quanty per each, wire is listed a quantity of feet, and heat shrink is listed as qty 1 = 2.25″.
For Example:
Qty 1 – Inverter Charger means you need to purchase 1 Inverter Charger
Qty 3 – 4/0 Wire means you need 3 feet of 4/0 wire. This may mean you need to buy 5ft from the product page
Qty 5 heat shrink means you need 5 pieces of 2.25″ heat shrink. This means you’ll need 5 x 2.25″ pieces of heat shrink for a total of 11.25″ of heat shrink.
Camper Solar Parts Detail
The section below will tell you where each of the parts from above fits into the wiring diagram. This is quite lengthy, but if you are having trouble seeing the diagram or just want more clarification that the diagram above doesn’t deliver, hopefully this will help:

I am looking at getting two 24V/3000 for my build. The question I have is, what is the difference between the multiplus and multiplus II? Should I get the multiplus II for updated equipment and software? I have looked at other sites and a so-called comparison of the two but I couldn't find a direct 24V comparison of the two.

When running 24v system with Cerbo gx can I use my stock tank monitor sensors?

Good evening Nate, I'm building a 24v system almost identical to this one. However, we have a few items that are 24v, (some lights, water pump, (2) USB chargers and a powered ball valve for grey tank). I'm very green to electrical, but I feel I would have a busbar before the Orion 24/12 that would branch one to the Orion 24/12 and then another to the 24v fuse panel? What are your thoughts?

Nate,
Victron is supposed to be coming out with a 24V version of the Multiplus II 2x120 later this year. Will you be doing a design using that with the large array and battery? If so when do you think you would do that and have you heard any definite dates for the 24v Multiplus II?
