Connecting Multiple Solar Panels To One Charge Controller

Yes you can have two controllers on a one set of panels array.

Connecting multiple solar panels to one charge controller. Connecting the solar panel charge controller mppt or pwm are the same solar battery and the pv array in the right way is the essential work before enjoying the solar energy. The white line is the negative connection all 3 panel negative wires are just simply tied together and to the wire that runs back to the negative connection on the charge controller. Large off grid solar and battery backup pv systems often require greater charging than a single controller can provide. You will see a symbol that looks like a triangle pointing down at a horizontal line.

The red line is the positive connection to the panels. Generally speaking it is a good idea to obtain your solar panels before you buy a charge controller. Connect the negatives to the negatives and positives to the positives.

Each controller is independent and the outputs will not be parallel unless you put them that way.
