I'm installing a 12v rooftop air conditioner on the adventure van from Velit. This thing is SUPER EFFICIENT and we can actually run it for a substantial amount of time off of our battery bank and solar. What a game changer!
In this video we do the full install and then multiple tests to see how it performs and how much power it uses.
