Connecting two different solar panels.

Here s something you can do. The most common question i get asked on a daily basis is. Connecting two solar regulators. Both have their own purpose and applications and both have different outcomes when hooking up solar panels of different wattage together.

The series connection is done by wiring the positive terminal of each panel to the negative terminal of the next panel a connection similar to the ones of the christmas lights until the final panel is connected to the charge controller or inverter. This is used when the solar panel is stored for travelling. Solar panels are usually connected in series to obtain higher output voltage. Call for a free quote.

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. They can be wired in parallel. 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. Connecting solar panels in series.

Can i connect two solar panels with separate regulators to my one battery bank a lot of people when they first start out with their caravan or motor home mount solar panels on to their roof almost by default. The combined power of the two panels would exceed the current handling capability. The wedgetail camper has two solar inputs via red anderson plugs. When the wedgie is open the roof hinges over 180 degrees and becomes the base of our bed.

On the other hand if our two solar panels have both different wattage and different voltage then parallel connection is not possible since the panel with the lowest voltage would behave like a load and would begin to absorb current instead of producing it with the. It s all in the wiring. There are two ways to wire up solar panels. 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.

Connect two large solar panels to one battery. Firstly lets take a look at connecting solar panels in series.
