Connecting Multiple Solar Panels To A Charge Controller

The connection of multiple solar panels in parallel arises from the need to reach certain current values at the output without changing the voltage.

Connecting multiple solar panels to a charge controller.

Generally speaking it is a good idea to obtain your solar panels before you buy a charge controller. The red line is the positive connection to the panels. 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. For example our 115w sunpower solar blanket has the following ratings.

Here s something you can do. The combined power of the two panels would exceed the current handling capability. Connect the negatives to the negatives and positives to the positives. Connecting two solar panels in parallel.

Large off grid solar and battery backup pv systems often require greater charging than a single controller can provide. Connecting in series means joining the positive terminal of a solar panel to the negative terminal of the next solar panel until eventually you are left with one free positive and one free negative terminal of the array which are to be connected to the input either of the inverter in case of a grid tied system without a battery backup or the charge controller in case of a grid tied system with a battery backup or off grid solar panel system. Then they are connected to the charge controller or to the inverter of the solar system. Connect two large solar panels to one battery.

Maximum rated current 5 8a. If both panels are rated at the same maximum voltage then you ll get maximum output. You can think of a charge controller in the same way that you would think of a hard drive on a computer. You will see a symbol that looks like a triangle pointing down at a horizontal line.

Maximum rated voltage 19 8v. Connecting solar panels in parallel wiring solar panels in parallel implies connecting positive terminals of each panel together and wiring the negative terminals of each panel together as well.
