I did subsequently tidy this jungle of wiring a little but this is the black magic behind my door opener control. One battery pack, one linear actuator, one DPDT 12V automotive relay and one BMW (or is it Harley Davidson) ignition switch.
In the post, my charge controller arrived from China but missing a chunk of plastic. Together with that, my 9V battery holder arrived. That's probably not needed now since I'm using a 12v battery pack.
The instructions are somewhat amazing as this charge controller protects me against thunder. That, I'm sure, will be very useful!
Having a couple of hours left before dark, I set to work and installed the first of my two solar panels. I didn't have enough rivets to complete the job but it's beginning to look good though my bus is now looking less anonymous.
Quite a fruitful day! Tomorrow I might get the second panel installed. I might even get the other one better aligned too!
