12 Volt Solar panel for 4 6v batteries in series parallel

Magnussan I think I bought the same kit as you. It works great. If you want us it as a portable that should be no problem. What you need to understand is wiring the controller in is nothing more than sticking the wires from the solar panels into the controller and running two more out to your batteries. It doesn't have to be set up permanently to do this. The controller will give your batteries the proper voltage from the solar panels.
