I have a small panel (80W), sufficient for my boat.
I want to be able tu cut off both panel and charge controller ("regul"), but also prevent a wrong manipulation (that is to say; panel connected to charge controller but charge controller not connected to the battery.
I have plan to use 2 bipolar switch, wired like in this picture.
Well here only the "+" is shown, to have it clear, but the idea is to set 2 switch, one on the "+", and another on the "-".
Is there any issue to do it this way ?
Any risk when the charge controller is connected to the solar panel and the battery simultaneously ?
