How To Connect 2 Solar Panels Together

The wedgetail camper has two solar inputs via red anderson plugs.

How to connect 2 solar panels together.

This is used when the solar panel is stored for travelling. If we have two solar panels with the same voltage but different wattage there is no problem. For example a 110ah battery should never be connected to a panel more than 11w without a solar controller and if you are using a solar controller you do not need a blocking diode. The first is on the roof.

Connect all the positive terminals of all the solar panels together and all the negative terminals of all the panels together. In a solar power system the higher the voltage and the lower the energy losses along the cables to know the maximum system voltage we usually just need to turn the panel and read the label where the value is reported. The rule of thumb when connecting solar panels directly to a battery is never connect more than c 10 watts where c is the capacity of your battery. By connecting multiple solar panels in series we increase the system voltage.

You have two different higher voltage solar panels i e one 100w 24v and one 200w 24v that you want to connect to the already working 12 v solar power system comprising the two 12v 50 w solar panels connected in parallel from the previous scenario see the picture above. When the wedgie is open the roof hinges over 180 degrees and becomes the base of our bed. It s all in the wiring. They can be wired in parallel.

After these clarifications let s see how the series connection takes place. So if you connect two solar panels with a rated voltage of 40 volts and a rated amperage of 5 amps in series the voltage of the series would be 80 volts while the amperage would remain at 5 amps.
