Hello there! Mitch here from FarmLite. I've uploaded the raw video of me hooking it up and explaining how to connect to solar. 

 

If you are showing power on the solar charge controller but your door doesn't have power then most likely some leads are not properly connected whether it be by color or just not good contact.

​

See the following two amazon links for the products used in the video! If you get plenty of sunlight then the 10W solar panel with the same charge controller and a 7 Amp Hour battery is a cheaper option!

                                                                     IMPORTANT

Red/Brown are positive (+) Leads and should be connected together.

Blue/Black are negative (-) Leads and should be connected together.
