Connecting Multiple Solar Panels To One Charge Controller

If you connect the output of each controller on two separate battery banks each controller will charge the bank that is connected to its output using whatever power is available depending on the need state of charge the battery bank has.

Connecting multiple solar panels to one charge controller.

You will see a symbol that looks like a triangle pointing down at a horizontal line. There is only a certain amount of data that a hard drive can store so you typically purchase a hard drive that is big enough for your needs. The red line is the positive connection to the panels. You can think of a charge controller in the same way that you would think of a hard drive on a computer.

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. Yes you can have two controllers on a one set of panels array. Each controller is independent and the outputs will not be parallel unless you put them that way. If both panels are rated at the same maximum voltage then you ll get maximum output.

For example our 115w sunpower solar blanket has the following ratings. To meet high power charging requirements several solar controllers can be connected in parallel to a battery bank with each controller connected to its own separate pv subarray.

Connect the negatives to the negatives and positives to the positives.

Generally speaking it is a good idea to obtain your solar panels before you buy a charge controller.
