Wire for Off grid solar systems
(I make a commission for purchases made through the links below)
Inverter to Battery Cables
Build your own with a kit!
|
Requires cable cutters and a large cable crimper. Check out what I recommend by clicking here.
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): |

Solar Panel Array to
Solar Charge Controller Wire
|
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! Click Here |
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. Click Here for Black Click Here for Red |

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. 50 feet 10 gauge Blue/Black Click Here |
Crimp Connectors
|
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 |
Large Cable Lugs
|
Large copper Terminal Connectors. Avoid the cheap ones. You have been warned.
I have a few boxes of these on hand at all times. Thick walls ensure a true cold weld every time. Click Here to Purchase |
Small Cable Lugs
|
Smaller than the connectors above, but covered with tin. This will offer protection from corrosion, but cost slightly more. I think everyone should have both on hand when building a system.

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.
Avoid the low quality ones! They melt. Buy these ones instead: 2 panel connector Click Here 3 panel connector Click Here 4 panel connector Click Here |
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.
