I am available for custom hardware/firmware development
I would like to thank all who helped me with the design of my solar setup on this thread. I put everything together this July at our place in Canada and it worked perfectly. Unfortunately the solar setup was overshadowed this year by us having to install a new metal roof on our cabin, so I was not able to permanently install everything. Instead, I had to build a temporary frame out of 2x4’s which I mounted 4 of my 6 panels to, so that we would have enough power to get us through with cell phone charging and other battery charging duties. We did run a vacuum cleaner a couple of times on it though. Almost every day, we hit float at about an hour or two after sunrise. I am very pleased with the outcome. At the end of our stay, I took everything apart and left the eight 6V batteries tied together in four 12V pairs and hooked them up to four Coleman solar charger panels. I’m hoping they will still be fine by the time we return next year.
