This wiring diagram will show you everything you need to know about installing the core elements of a high-end camper solar electric setup. This system features a 2000 watt inverter, can handle MANY different configurations of solar panel arrays up to 700 watts with no changes to the core wiring of this diagram, and allows for charging from the alternator as well as shore power. This is a long read and if you have questions, drop them in the comments below or if you feel you need additional guidance, you can set up a call with me: CLICK HERE for more info.

DIY Camper Van Wiring Diagram
A Note about Quantities
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″.
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.
Qty 8 – 2/0 x 5/16″ Wire lugs means you need 8 wire lugs… not 8 packs of wire lugs.

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:
Choosing your Solar Panels & Charge Controller
The following section provides you with several different options for solar charging. The above parts list can remain completely unchanged and the diagram above can remain mostly unchanged except for the alterations noted by the diagrams below, but whatever solar array setup you choose below for your needs, these parts will need to be added to your shopping list. These are broken up by total solar wattage. As a general rule, you want to have twice as many watts of solar as you do amp hours of batteries. So, 300Ah Batteries = 600W solar. 400Ah Batteries = 800W solar. 600Ah Batteries = 1200W of solar. This is just a rule of thumb. Not a law.
