Custom-built system inverter/solar charge controller connection wire (requires crimping)

Picture
High Quality Pure Copper Large Wire Gauge Cable/ Connector/ Heatshrink Kit for Custom Built Systems

Requires a Hammer-type/Large Ratchet Crimper and DIY Assembly. Great for custom-built systems where length of each wire matters. If you are a beginner, stick to the cables above.


Click on a link below and choose your wire gauge
​(default length is 10 feet of red, 10 feet of black): 
  • 8 gauge kit
  • 6 gauge kit
  • 4 gauge kit
  • 2 gauge kit
  • 1/0 gauge kit
  • 2/0 gauge kit
  • 4/0 gauge kit​

Solar Panel Array to Solar charge controller wire

Picture
​Solar Panel Array to Solar Charge Controller Cable

This is a beginner friendly wire kit that connects your solar panels to your solar charge controller. It has mc4 adapters attached, so this is a plug n play solution.
(this cable goes through your roof):

Advanced user solar panel array to solar charge controller cable

This is temco. It is high quality pv cable that is great for long wire runs (even hundreds of feet!) This wire requires cutting stripping and crimping the appropriate connectors. I have spent hundreds on this cable and it has every safety rating imaginable. Highly recommended!

DC Load Hook up wire

High quality automotive rated
​10-14 gauge wire

​Use this to connect critical loads to your fuse block. This is tough wire that can last for ages and handle oil/water/vibrations and more! Great stuff.

High-Quality Copper Wire for DC appliance hookup
(most wire on amazon is "copper clad aluminum", which is cheaper but lower in quality):

I love this stuff! Two wires in one, which means faster install time versus individual wires.

Crimp Connectors

Picture
Standard Size Crimp Connectors (22 gauge wire-10 gauge wire)
Use these to connect various parts of your system together. Be sure to buy high quality connectors or you will have problems. I have used cheap connectors in the past that have overheated and failed. These connectors are what I am currently using: Click here

Picture
Large copper Terminal Connectors.

I have a few boxes of these on hand at all times. Thick walls ensure a true cold weld every time.

Picture
Large Size Crimp Connector Set (8 gauge wire- 4 gauge wire)

Smaller than the connectors above, but covered with tin. This will offer protection from corrosion, but cost slightly more. These lugs are also not as large as the lugs above. I think everyone should have both on hand when building a system.

When you crimp large terminals, it is preferable to not have insulation while crimping (to ensure a good crimp). You can add insulation after if you wish, or wrap it with electrical tape.

Branch Connectors

​Wiring multiple panels or groups of panels together in parallel requires a branch connector. This will allow you to only have 2 wires going through your roof and to your solar charge controller.

Solar Panel Array Cable Entry Gland

When your solar panel array wires enter your vehicle, you will need to drill two holes. Use this cover to prevent roof leaks from developing.
