Waypoint Vehicles x EXPLORIST.life Camper Electrical Install

This blog post will show you how to install a high end campervan electrical system in a Mercedes Sprinter.

This Sprinter Camper electrical install was designed and installed by me, Nate from EXPLORIST.life, into a Mercedes Sprinter Camper Van built by Waypoint Vehicles, a newly launched professional camper van up fitter based in Los Angeles – focused on building premium adventure vehicles, using only the best of the best products available. This was truly a fun project and I’m excited to share it with you.



This blog post will show you the wiring diagram used, the parts necessary for install, as well as some additional details about the install process.

Waypoint wanted a top-of-the-line camper electrical system, with the ability for customers to expand their systems and evolve over time as needed. This system features a 100% Victron Energy based powerplant with Blue Sea Systems and Switch Pros integration for AC and DC loads which can be switched from multiple locations in the van via touchpad or a smartphone app.

This diagram features:

  • 3000W Inverter Charger
  • 600 Amp Hours of Battery Storage Capacity
  • 180W Solar Array Capacity (Expandable to 440W)
  • Alternator Charging (60A)
  • Shore Power Charging/Passthrough
  • System Management via Victron Connect app & Cerbo GX w/ Touchscreen

Full Parts Kit For This Install

There are a TON of parts necessary to complete this project. Not only the Inverters and batteries, but lugs, heat shrink, copper washers, ferrules, signal wires, and a ton more. The itemized parts list for all (most) of these parts is listed below… but if you are planning on tackling this project yourself, you should check out the kit I helped Waypoint Vehicles assemble so you can get all of the components delivered to you in one go and save yourself 30 trips to the hardware store (only to find that the hardware store doesn’t have what you need). This is truly going to be the easiest way to source all of the parts for this project. Here is the link to that kit: https://waypoint-vehicles-store.myshopify.com/products/ultimate-power-package

DIY Camper Solar Parts – Shopping List

The parts list below is a consolidated parts list for this entire system. This list is about 90% complete as I am having trouble sourcing a few items, but this should get you pointed in the right direction (but those parts are included in the Waypoint x EXPLORIST.life kit linked above).

IMPORTANT NOTE: For the ‘Quantities’ in the below shopping list, each singular component is listed a quantity 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.

Hi Nate,

What do you recommend to torque the SmartShunt's M10 brass bolts to. Victron's instructions do not list a torque value for these.

Thanks Jack Gerber

It appears that most if not all of the DC/DC chargers in your diagrams are Isolated. Is there a reason to not use non-isolated in a van build? In this diagram a 6AWG cable feeds a 100 amp breaker then 2 more 6AWG cables feeds to 2 DC/DC chargers. Is a 100 amp breaker appropriate on 6AWG given you use 40 amp fuses at the other end on 6AWG?

Thanks Nate for the awesome writeup and videos. I'm looking to start with 1 Orion and didn't know if you had an opinion on adding a second to get 60 amps of charging. Lots of debate saying that a VS30 Sprinter should handle up to 75amps no problem for accessories. I don't think the Sprinter has a second accessory fuse slot and not sure what the best way to wire in that scenario. Curious your thoughts if a good idea or not?

This is great thanks so much. Do you have the dimensions/ layout for mounting structure over wheel well?

Nate,

Can you recommend a Victron Ambassador in which I can talk to? I have some specific questions in which I cannot get responses on. I am wanting to complete my electrical with all Victron, yet again, without your paid consulting it appears that you are not an acting Victron Ambassador to assist with the system? Who is willing to help?

Thanks for a response. Fred
