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:

Hi Nate,
I was just curious if both of the inverters are supposed to be connected to the AC loads breaker box? It looks like both of the hot legs go in the box but one of the inverter cables only has the hot leg (red) in the breaker box but all three lines coming out of the inverter? Is that correct or should both inverters have all three legs connected in the breaker box?

Hello, for power distribution center you suggest PD55K000 in this page. Is that the correct one because PD55K000 is 10 Dual (50Amp 240VAC)? If all it gives is 240VAC, how am I going to use the 120VAC loads? Would I just use one half of the double pole breaker?

You'd just use a single breaker as opposed to a dual breaker for 120V loads. 240V split phase circuit is made up of 2x 120V circuits and you can use just one of them for 120V loads; just like in your house.

Thanks for this! It helps a lot.
In the "Battery Bank to Busbars" there is a 400a fuse, but the disconnect is only rated to 300a. Is that a concern?

Nope. The actual anticipated amperage flow of this system is about 250A. The switch is sized for that.

Thank you for all the great information.
As we get closer to installing our solar system on our Class A RV, I'll be in touch to discuss our needs, specifically running a 230v two zone mini-split.

Nate,
The 100A DC to DC Buck converter, as I understand it requires a smart alternator, is this correct?
V/r,
