Solar Panel Disconnect/Isolation Switch?
The display panel in the solar controller (Go Power GP WM25) in my 2010 17B appears to be defunct. Tech support at Go Power suggests a hard reset, which involves disconnecting the input and output wires from the controller. I do not have anything which tells me if there is a disconnect/isolation switch between the panel and the controller. I am reluctant to just jump into the task without some assurance I will not be shocked due to the panel putting out current while I am working around the controller! Is there a switch as part of the installation, and where is it?
I suppose I could just cover the panel with a piece of cardboard, but there must be a better method.
