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:

In the diagram you are using a DC that combines 240v and 12v, but the DC in the parts list is for 240/120 only. Is there a combination box you recommend so that I may keep all of my wiring coming into a single DC?
Thank you

Is using a pair of the new 24-2x120V MultiPlus2 easier than this setup for an new 50A 5th wheel? I believe there is less programming around the split phase and just the parallel communication cable between them, setting one to primary and the other to secondary for the most part. The rest should mostly be the same other than, on the AC side, combining the outputs for 6kW and splitting the inputs so both units can charge/passthrough.

What is the rationale on how the shunt power connection is placed? according to the Victron install for SmartShunt notes the power cable should be installed between the shunt and the positive battery.

Hi Nate -
I am able to swap out the multiplus for the multiplus 2 in 24v/6000w wiring diagram? Or are there other considerations?

I am using your design as a starting point for what will ultimately be a 2X 24V 5k Quattro system. Would that mean doubling the stated wires (and I assume higher amp switch, and shunt )?
