Take a look at the first module and you'll notice that it has two wires extending from the junction box.

This article addresses MC4 connectors, but the same principles apply to other connectors such as Amphenol H4, Tyco, and SMK. You must insert the two extended posts on the end of the tool into the side of the female MC4 connector. The second was 3x 410Watt fixed frame panels, with all the charge controllers, circuit breakers and accessories needed. so their plus factors are that they hold together well and their negative factors are that most users find them a challenge to take apart.

My thought is to have a short (less than 2ft) wire coming from the controller on the panels as well as coming off the 12V male plug that connects to the trailer. and the adaptor is very easy to connect your solar panel chargers and the other battery chargers with the SAE connectors.

A series connection is when you wire the modules together by connecting the positive lead on one module to the negative lead on another module. Naturally, if it is possible to keep SAE connectors together as long as possible there will be less wear and tear to reduce pinch and less exposure to corrosive conditions.

When we got our 550 the suitcase choices were too expensive for my taste so I bought an inexpensive panel that would fit in our small TV. One type accepts two male MC4 connectors on the input side and has a male MC4 connector for its output. Modern solar modules tend to use the MC4 connectors because they make wiring your solar array much simpler and faster.
