How To Wire 2 Portable Solar Panel Together

Two arrays two 10a charge controllers connect both in parallel to the same battery bank.

How to wire 2 portable solar panel together. If both panels are rated at the same maximum voltage then you ll get maximum output. When you connect two or more solar panels like this it becomes a pv source circuit. The only difference is you had to purchase a separate 20a charge controller. There are two ways to wire up solar panels.

Solar panels are usually connected in series to obtain higher output voltage. Connecting two solar panels in parallel. To power a dual battery system you ll need to connect the panels in parallel. Two arrays connect in parallel to one 20a charge controller run cable to battery bank.

If you look at the arrows along the white and red lines they are showing the direction of flow. If we have two solar panels with same voltage and power the connection will be very simple. 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. 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.

To wire two or more solar panels and batteries in parallel simply connect the positive terminal of solar panel or battery to the positive terminal of solar panel or battery and vise versa respectively as shown in the fig below. In this first image there are 3 solar panels. Parallel connection of two identical solar panels. Solar panels are wired in series when you connect the positive terminal of one panel to the negative terminal of another.

Yes the results are virtually identical. When solar panels are wired in series the voltage of the panels adds together but the amperage remains the same. As clearly visible in the picture it will be enough to wire the positive pole of one panel to the positive pole of the other one and then wire the negative pole of one panel to the negative pole of the other one. Connecting 2 130w folding solar panel sets together.
