I spent most of today working on my honey-do list that my wife gave me. One item on the list was to put the Christmas lights up. As I was putting the lights up an idea started brewing in my head. Why not run the lights off of my small solar setup? This will be a good workout for my batteries and will be a good test to see how quickly the batteries recover the next day.
As of right now, my system is tiny. It consists of a pair of old 100 amp/hr AGM batteries, a single 50 watt solar panel, and a cheap MPPT charge controller. Testing today showed the panel putting out an average of 2.5 amps of current through the charge controller for 4 hours and 2 amps for another 3.
So starting tonight, I will be running about 200' of led lights for a few hours and I'll see tomorrow how long it takes the batteries to recover.
