Solar powered switch
My 300 watt system is at a remote cabin I use intermittently. Whenever I’m there I turn on the inverter, the ceiling fan, etc. just to challenge the batteries a bit, which are always 100%. The cabin has a 4ft tall “crawl space” where the batteries and system components are located. The humidity in this space is always higher than I would like it. I now have a heat lamp in the basement which I turn on whenever I’m there. It really helps control the humidity and never effects the battery SOC on sunny days. What would ideal is for the heat lamp to be on whenever the sun is shining brightly, whether I’m there or not. The cabin is in Eastern Kansas where we have many sunny days. What I need is a switch that would control the heat lamp; on when the sun shines brightly, off when it doesn’t. If it matters, the inverter could be on all the time. Any ideas on a “solar switch” with this capability?
