How to Set Up a 12 Volt Solar Power System

Today we are installing the Renogy DC to DC MPPT Charge Controller (https://amzn.to/3NXDJiJ). Although I have had troubles with this unit in the past, it is a really cool charge controller and I do recommend it. This charge controller has the capabilities to charge both your house batteries and your starter batter from your solar panel. It also has a built-in DC to DC charger to charge your lithium batteries while you drive as well as from the solar panels. It really is an awesome unit for van life. The only downfall to the unit is it's only capable of inputting 25 volts from your panel. So if your array puts out more than 25 volts this isn't the unit for you.

In this video, I go through a few basic components of the van conversion solar system and also show you how to do a few wiring basics. My camera died while I was wiring the whole system and had no idea so I missed a few key parts of wiring the charge controller.

We also installed our Aims Power pure sine 2000W inverter to a MidNite Solar breaker box and we will also be wiring two 120-volt AC outlets in the van from the breaker panel. I really enjoy installing all the electrical components in a van conversion and these are easily my favorite steps.

Wiring the breaker panel is very straightforward and only takes a few hours. I will recommend checking out the links below and making sure you have everything ordered and ready to be installed. I had to wait a while to get a few parts and it really delayed the electrical installation and I had to start working on upper cabinets. I really liked this power inverter, especially with the auto transfer built-in. I like the idea of being able to charge the unit via shore power. It was also very easy to set up the shore power input.

Be very careful when doing this project always check your connections with a multimeter to see if they are hot. I installed a few kill switches so I could completely kill my system while I was working on this project.

You can get seriously injured or die when working with this inverter so take this project seriously. If you have no idea what you are doing call your best electrician friend and have them help you. Or call a licensed professional.

I made this video because I had a hard time finding a video that ran me through the parts I needed for this project as well as the steps to do it. I hope this helps some of you kookz out there.
