Note: Never connect or disconnect solar connectors whilst they are under electrical load as this can cause arcing which can damage the contacts. SAE connectors can get snug to seat fully, which is a good thing as opposed to being sloppy and sliding in easily. When looking at kits you can see details of the products included with the links in the Specification tab.

If you're asking this question, you've probably noticed that most modern high power solar modules are manufactured with wire leads that have latching connectors on the ends. Since it is a portable system I intend to babysit it anytime it is in use and much prefer a small, one time, added cost to have the faster charging panels.com/p/Renogy-Male-and-Female-Connector-to-SAE-Adapter-13-AWG-Cable-CNCT-MC4-SAE/301811354" on this server. Most solar panels don't have SAE connectors, they use MC4 connectors so you will need an MC4 to SAE connector cable.

Note: Please be sure to double check that you have the positive and negative the correct way around, it is often the case that you will need to make use of the reverse polarity adapter (included) to ensure the correct positve and negative wire run all the way from the solar panel to the SAE connector. You need to keep the polarities straight with the SAEs but other than that I find them excellent, simple and have had no problems at all. That allows you to plug into both leads of your solar panel and it gives you plenty of wire to get to your destination. Take a look at the first module and you'll notice that it has two wires extending from the junction box.To travel the 20-foot distance to your equipment, you will need a 20-foot wire with a male connector and a 20-foot wire with a female connector. Generally, the female MC4 connector is associated with the positive lead and the male connector is associated with the negative lead. You must insert the two extended posts on the end of the tool into the side of the female MC4 connector. The two 170W flexible panels fit well on my Bimini and now I generally don't bother hooking up to shore power.

The total number of modules that can be combined will depend upon the electrical rating and physical size of the combiner box. In this case, you will want to cut the extender cable at a spot that allows both cut ends to reach the combiner box with a little slack to work with. For my set up I am using this to connect a solar panel hub (*arbor *rieght) to Renogy extension cables to Renogy charge controller adapter kit.I retrofitted my trailer with one and use a SO cord with a Marinco connector on one end to fit the trailer and MC4 connector on the other end to fit the panel. SAE make a lot of sense to me if you keep them clean and put up daily, and my guess is a bit of vinegar will help dissolve salt or scale buildup from being outside. Solar-specific, UV-resistant extension cable with a 4mm² conductor cross-section for connecting solar panels. One type accepts two male MC4 connectors on the input side and has a male MC4 connector for its output. These seemed like the perfect solution and they appear to be of good quality but I have not installed them yet.

Tip; separate type connectors but useful related to how not to get gunked up electrical connections pro-tip; (thank you Craig and Cary for diagnosis, finding this issue while refusing to let me leave on a late hectic Friday after factory owner tour.and the adaptor is very easy to connect your solar panel chargers and the other battery chargers with the SAE connectors. Comes with reverse polarity adaptor - please ensure that the positive and negative from the panel match with the connectors as often the MC4 connectors in particular will be reversed.
