In this practical guide, we will walk you through the process of how to hook up solar panels to houses, from understanding the basic components to the step-by-step connection procedures.
The first method we will look at for connecting solar panels together is what's known as “ Series Wiring “. The electrical connection of solar panels in series increases the total system output voltage. Series connected solar panels are generally used when you have a grid connected inverter or charge controller that requires 24 volts or more.
Connect the 2 positive solar panel cables to the compatible Y connector. This will likely be the FFM connector. (FFM stands for “female, female, male,” meaning the Y connector with 2 female MC4 connectors and 1 male MC4 connector.) Then connect the 2 negative solar panel cables to the other Y connector. This will likely be the MMF connector.
Wiring solar panels in series is arguably the easiest of the three methods. In series wiring, the positive of one panel connects to the negative of the next, and so on. This creates a string of panels with a negative wire at the beginning and a positive wire at the end. However, wiring in series is not always as straightforward as it seems.
These are Y branch connectors: They're used for wiring 2 solar panels in parallel. You'll need to get a pair to complete these steps. Connect the 2 positive solar panel cables to the compatible Y connector. This will likely be the FFM connector.
The steps to add solar connectors to PV wires are the following: Strip the wire. Place the connecting plate on it and use the crimping tool. Insert the lower components of the connector (terminal cover, strain reliever, and compression sleeve). Insert the upper components (safety foil, male/female MC4 connector housing, O-ring).
While connecting solar panels to the inverter, ensure that the input voltage does not exceed the maximum voltage level or total power. This will determine the number of solar panels connected in series in one string. – Check that the voltage rating meets the requirements for the location in which you are installing the solar system.
