Solar Array to Charge Controller Disconnect Breaker "Lowes"
Main Sections
50 amp charge controller disconnect breaker by square D QO
In the picture you can see the simple wiring of
the solar array to charge controller disconnect.
This is a “Square D” QO 50 amp DC
breaker. It is used as a disconnect between
the solar array and the controller.
As with the charge controller to battery bank
disconnect it is a very simple setup. The
positive wire runs from the positive solar array
out put through the breaker and on to the
controller. The negative runs from the negative
output to the solar controller. You do not
want to put a switch on both wires, Make
sure the cables you use have the correct amp
rating for the breaker size and wire run length.
This was a good place to bond the system DC
negative cable to the ground.
