Connecting Multiple Solar Panels To One Battery

Connecting two solar regulators.

Connecting multiple solar panels to one battery.

How to connect two solar panels to one battery. Here are a few of the terms that are important to know when solar charging two battery banks. This setup is ideal if you have multiple solar panels that do not have the same rating. 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.

Always connect the rv house battery bank to the first battery position as it will receive the full charge before the second battery begins to charge.

Solar charge controller keeps the solar panel from over charging your battery or batteries. Strings to multiple charge controllers and one battery. In this way we will get an excellent energy storage system. In fact by wiring several solar panels in series we increase the voltage keeping the same current while wiring them in parallel we increase the current keeping the same voltage.

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 connection of multiple solar panels in parallel arises from the need to reach certain current values at the output without changing the voltage. 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. The most common question i get asked on a daily basis is.

In this example there are two strings or arrays of solar panels that go to every charge controller. Refer to the article about series and parallel wiring solar panels.
