MC4 Cables & Adapters
An MC4 extension cable is very similar in concept to an electrical extension cord. Just like an extension cord has a male plug on one end and a female plug on the other, an MC4 extension cable has a male connector on one end and a female connector on the opposite end. They are available in many different lengths from 8 feet to 100 feet long. Lets go back to our first example of wiring two modules in series. Once you’ve got the two modules connected in series, you need to use MC4 cables to bring that power to wherever your electrical equipment is located (usually a circuit breaker and a solar charge controller).
MC4 Cable Adapter
The MC4 Multi Branch Connector is used with the MC4 extensions when two solar panels are configured in parallel.
When you purchase the Y cable adapter you will receive the two pieces shown in the photo.
