CLICK SUBSCRIBE**A quick overview of my solar set up being installed in my ’88 KIT Companion. It is a work in progress. There are two 180 watt solar panels wired parallel for a 24 volt output that matches the Hybrid wind and solar charge controller. This connects to a 24V to 12V converter for the batteries. There are many more pieces yet to install to complete this set up. If you like the video please subscribe and hit that like button. Thanks for watching. MORE ON THIS SET UP AS IT GROWS.
