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!
