Main Component Hook-up wire/connectors/heatshrink
Requires a Hammer-type Crimper and Assembly. Great for custom built systems where length of each wire matters. If you are a beginner, stick to pre-fabricated cables. Click on a link below and choose your length (default length is 10 feet of red, 10 feet of black): |
|
Branch Connector
Wiring multiple "in series groups" together requires a branch connector. Connect all of your panels together on the roof and combine them into two wires which will connect to the solar panel extension cable (Solar panel to charge controller cable above) 2 wire connector (4x required for 800 watt system) Click Here |
|
Buy 2x Solar Panel 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. Click Here |

Connect 12 volt appliances here with this fuse block. Easy to use and easy to install! These are great.

Solar Panel Mounts:
Every vehicle is different, so check out my book and this page (click here) to figure out how to mount your solar panels
Battery Monitor:

This device will tell you how much power you have left before your batteries go to zero. Simply attaches at the main negative lead of your battery bank.
Click Here to purchase If you want a higher quality battery monitor with bluetooth connectivity and data logging, check out the Victron Smart Shunt instead. It does cost more, but it is a fantastic device that I use on all of my systems: Click Here |
Required Tools:
|
|
Hammer Type Crimper
Can crimp up to 4/0 gauge wire, and it is much cheaper than the 3 point crimp tool. If you plan to build only one system, this is the tool for you. If you want to build multiple systems for years, but the 3 point crimper. Click Here |
|
High quality manual force crimper
The long arms provide a lot of leverage and I can usually crimp anything under 8 gauge. Click Here |
|
Crimp Connector set
There are cheaper crimp connector sets available, but they are junk! Spend the extra money and buy a high quality set of connectors. The cheap chinese ones will fail and I have had it happen before. This is what I currently use: Click Here |

When connecting fans or lights or pretty much anything, use these quick connectors that are rated to 60 amps! I have used them for years for my rc airplanes and helicopters, but they are insanely useful for living in a rv.
