I built a cold frame for starting seeds this year. Used a free patio door that the neighbor was tossing out, and 2×8′s from a deck that I am removing. Made for a very heavy box, but it’s well insulated that way.
Hope this helps give ideas, I just want to contribute to pay back the YouTube community for all the videos that I’ve watched and helped me out. Thanks all!
If you know what is the problem in Amps readings please let me know, it is really appreciated!
Seems me that the panels are connected properly, it gives Volts, but no Amps. The connection is the same as here: https://www.youtube.com/watch?v=Hey1QZkYFSQ
Thank you for suggestions!
