History of Changes to this Page (Click to Expand)

Changes Made Nov 28th, 2021: MAJOR UPDATE. Updated diagram to add more detail to the individual parts (labels on lugs, heat shrink, etc). Also added a pg 2 to the high resolution diagram to include the system from the following video: https://youtu.be/01F4QDVJUq0 There are very minor details changed between the two pages except for the solar array. Added seperate AC and DC distribution boxes as we have started sourcing those and selling those in-house so sourcing bottlenecks should no longer be an issue. Updated parts lists to include the EXPLORIST.life wiring kits.

Changes Made July 17th, 2020: Changed main DC Distribution busbars to be the Victron Lynx Distributor system instead of the EXPLORIST.life busbar. The EXPLORIST.life busbar is still available to be a DIY solution but I simply could not keep up with the demand for making these. Building busbars was taking up so much time I was having to neglect producing more videos and blog posts, which is what EXPLORIST.life is really about. The Victron Lynx Distributor is an all in one DC distribution unit that houses the fuses, positive and negative busbars needed to take the power from your battery bank to your individual main components. This product is an EXTREMELY elegant solution I think you will be very happy with. I also added an inline fuse and fuse holder between the battery bank and Victron Lynx as well as an inline switch. If you have any questions, as always, leave them in the comments below.

Changes made to diagram July 8, 2020: Changed equipment case ground wires to daisy chain back to the negative busbar instead of each having their own individual runs all the way back to the negative busbar. This results in less wire used, less clutter, and more free space at the negative busbar. I also removed the 300 amp terminal block at the house battery in favor of a 400 amp ANL fuse attached to the busbar. The 300 amp terminal block is adequate but I have heard of isolated events of this fuse blowing prematurely. When a 3000w Inverter is running at full capacity, it could be pulling near 250 amps. At surge capacity and heavy DC loads from around the camper, it’s possible the 300 amp terminal fuse could blow under normal, safe operation. If you are reading this and already have a 300 amp terminal fuse attached to the house battery bank; you do not need to replace it UNLESS it starts blowing prematurely. Finally, the 50A terminal fuse attached to the house battery bank protecting the wire going to the battery to battery charger was replaced with a 60A terminal fuse as I could not find a 50A terminal fuse in stock. If you have a 50A terminal fuse in that location, that’s completely fine and you need to make no changes.

Changes made to the parts lists July 8, 2020: A complete audit of all of the parts on this page was performed. Supply chain issues took a toll on this page recently and left many of my links incorrect. I have found a way to keep up with my links in a much easier way I have been doing in the past which means the links on this page should be MUCH more accurate going forward. Also, I added MULTIPLE different solar wiring examples to the bottom of this page so you can choose which solar configuration suits your own needs rather than providing a crash course in solar array design as that was proving to be too complex and therefore leaving the ‘done for you’ nature of this blog post lacking.

This page was originally published February 27, 2020

Thanks for your patience with these changes. I’m constantly trying to find better ways to teach this stuff and these parts lists and diagrams will be continuously optimized over time. -Nate

This section contains all of the parts necessary to wire the battery bank to the main DC distribution busbar. 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.

Shore Power to Inverter/Charger
This section includes the exterior shore power outlet and shore power cord that allows you to plug your camper into shore power as well as all of the wiring that allows you to connect the exterior shore power cord to your inverter charger. This will allow you to not only use shore power for powering your devices but also allow you to charge your batteries from shore power. Note: 10/3 w/ ground wire you will find at your local hardware store will very likely have 4 wires in it, which is unnecessary. The link for 10 AWG Triplex Wire below has 3 wires inside, which is correct for the application.

Inverter Charger to AC Distribution
This section includes the wiring necessary to connect the inverter charger to the AC side of the AC-DC power distribution panel listed in an earlier section. A quick note... 6/3 stranded wire is used here because although our shore power is 30A max, which 10 gauge wire is adequate for, the PowerAssist function of the Victron Multiplus Inverter Charger can add up to 3000w of battery power to shore power in the event that more power than the shore power can provide is needed. This much power coming from the Inverter/Charger requires 6 gauge wire feeding a 50A main breaker in the AC distribution panel. Also... the 6/3 w/ ground wire you will find at your local hardware store will very likely have 4 wires in it, which is unnecessary. The link for 6 AWG Triplex Wire below has 3 wires inside, which is correct for the application.

Solar Charging Parts List & Wiring Diagrams

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.

Order of Operations for DIY Camper Solar Install

This list is a rough guideline of what order things need to be connected for systems using this wiring diagram. THERE IS MORE TO KNOW about this process, though, in the user manual for each component. READ THE USER MANUAL FOR EACH COMPONENT as this ‘order of operations’ does NOT supersede anything in the user manual.

  • Arrange all parts & components where they will be mounted
  • Mount & secure all components to the wall/enclosure as necessary (EXCEPT Lynx Distributor)
  • Wire battery bank together
  • Assemble Lynx Distributor, master disconnect switch & shunt assembly
  • Mount Lynx Distributor to wall/enclosure
  • Verify Main switch is in the “OFF” position
  • Wire Positive wire from Lynx Distributor to Main fuse
  • Wire Positive Wire from Main fuse to Battery Bank
  • Wire Negative Wire from Shunt to Battery Bank
  • Connect negative wires from Lynx Distributor to Inverter/Charger, Charge Controller & 12V Fuse Block
  • Install fuses inside of Lynx Distributor
  • Connect Positive Wires from Lynx Distributor to Inverter/Charger, Charge Controller & 12V Fuse Block
  • Connect Positive Wire from Lynx Distributor to B1 Terminal on Shunt
  • Verify dual-pole disconnect switch for solar array is ‘off’
  • Connect Charge Controller to Dual Pole Solar Disconnect
  • Connect wires going to solar array to dual pole disconnect
  • Cover Solar Panels with Cardboard
  • Connect solar array together (Order does not particularly matter)
  • Remove Cardboard from Solar Panels
  • Verify proper solar array voltage at dual pole solar disconnect
  • Remove ‘wire bridge’ on Victron Orion DC DC Charger
  • Connect positive & negative wire from Orion to Starting Battery pos & neg (as per user manual)
  • Adjust Orion Output Voltage Setting as appropriate in Victron Connect app
  • Connect 10/3 wire from shore power inlet to Inverter/Charger
  • Connect 6/3 wire from Inverter/Charger to AC Breaker Box
  • Verify all 120V breakers in breaker box are ‘off’.
  • Connect AC Branch Circuits to AC Breaker Box if not already connected
  • Connect DC Branch Circuits to 12V Fuse Block if not already connected
  • Connect RJ-11 cable & BMV-712 Monitor Gauge to Shunt
  • Verify proper voltage between main fuse & shunt (Approximately 12V-14V)
  • TRIPLE CHECK THAT ALL WIRES ARE CONNECTED, POS (+) TO POS (+) & NEG (-) TO NEG (-) (except series wired solar panels) AND CONNECTED TO THEIR PROPER PLACES IN THE COMPONENTS AS PER THEIR USER MANUAL
  • Turn on Master Disconnect Switch
  • Turn on Dual Pole Solar Disconnect
  • Replace wire bridge in Orion
  • Turn Inverter/Charger ‘On’.
  • Turn on Main AC Breaker in Breaker box & Branch Circuit breakers
  • Configure system charging through the parameters as per user manual of each component

Hi Nate I was wondering if there was any drawback other than more consumption from the inverter if I go with the multiples 3000 with on 200 amp/hour of battery and add battery as needed?? I feel that it would be easier to just upgrade the batterie bank if I need more power. But if I go with the 2000w and want more power replacing the inverter and all the wiring sound like a lot hassle.

Thanks for all your info!

I started making a list from your solar parts above. When I clicked to view the 120V AC distribution panel, your shop window opened with two items on it, the PD55K004 distribution panel for $95 and a wiring kit for $125. I went to power dynamics website. Although I don't see the K004 model listed, others list for $65. Why is yours $30 more?

Also am I to assume the wiring kit would be redundant if I get everything else on your buy list above? For example, there is a 50A breaker listed in both places but only one is shown in your nicely detailed high res PDF diagram.

Hi Nate - your page has so much information it is amazing. Thank you so much for taking the time to put it together..

Two questions. 1 - if I were to add a circuit breaker to each battery (on the positive post), how would I choose the amperage for each battery ? Is there an equation?

2- Similarly - when choosing the amperage of the ANL fuse / Circuit breaker on the positive run from the battery bank (before the master cutoff switch in your diagrams) - how do you choose the size of that fuse? Like, is it different if I have a 600ah lithium bank vs a 1000ah AGM battery bank, etc ?

THANK YOU! :)

Hello, I've wired up my rig using the above plan, it's awesome. I am adding a 12 volt air conditioner and need another 80 amp fuse. Being there is no more room in the lynx distribulor, I'm not sure where to tie in. Would I tap off the right side of the LD or the left before the shunt. I'm concerned about messing up the BMV reading properly.

Thanks in advance
