Hey Dave, glad you enjoyed it! I will be picking it up soon and getting it to our soon to be bought house! Hopefully be doing more work on it this year. I will have to look into that on the switches. I had an electrician work on this with me. The lights are all on 12vdc from the batteries. The plugs are on 120v, the solar system comes with a converter. It also can plug into shore power, we have switches for that as well. Which I will have to get done a bit better, we were in a rush haha! Ya glad you liked it!
