24V – 6000W – 120V/240V Split Phase Camper Solar Wiring Diagram

24V – 6000W – 120V/240V Split Phase Camper Solar Wiring Diagram

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:

Battery Bank Wiring

This section contains all of the parts necessary to wire the battery bank together. These products include the batteries as well as the related wiring parts that you will need to make the battery to battery connections.

Battery Bank to Busbars

This section contains all of the parts necessary to wire the battery bank to the main DC distribution busbar (Lynx Distributor). The busbar itself as well as the shunt for the battery monitor and fuse mounted inside to the busbar protecting the positive wire from overcurrent can be found in this section. The busbar is essentially an extension of the battery terminals and allows you to deliver power where it needs to go and houses the fuses necessary to protect the wires leaving the busbar. The Battery monitor allows you to know how full your batteries are, know how much power you are actively gaining or losing, and see the historical data of your power usage.

Busbar to Inverter/Charger

This section contains the Inverter Charger and all of the parts necessary to wire the Inverter Charger to the Positive and Negative busbars. The Inverter Charger allows you to re-charge your batteries from 'shore power' and also converts the 24v DC power stored in your battery bank to 120V AC power like you'd find in your standard household wall outlet. The Dual Inverter setup shown also allows 240v power to be provided to 240v appliances through a 120V/240V breaker box.

A few questions arise from this: #1: Why go with the Dual 3K invert over the 5K Quattro(which has 120V 240V Split Phase) - other than the obvious -1K output difference #2: Speaking with Battleborn – they have an aversion to 24V systems, due to “balancing issues”. Thoughts?

Hey Eric!

1: The Quattro does not have 120V 240V split phase. If 120V/240V split phase input/output is desired, 2x Quattro's would need to be used similar to the diagram on this page. There 'was' a 120V/240V split phase Quattro about 10 years ago; but it was discontinued at some point and is no longer available.

2: My 'thoughts' are that as long as they say that "Battle Born Batteries are capable of being connected in series up to 48V" in their user manuals, it is fine. If they are TRULY averse to wiring their 12v batteries in series or series parallel to make a 24V battery bank; they would put that in their documentation.

Is the diagram shown 400ah or 800ah of batteries?

I am using 2 lifepo4 8s24v batteries, I will run them in parallel. My question do I actually have to wire the batteries together or can I hook them to a bus bar to achieve the parallel connection?

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?

Nate Yarbrough

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.
