Solar Panel Connectors 10AWG Compatible with MC4 Connecter to SAE Adapter PV Extension Cable Wire for RV Caravan Solar Panels Battery Charger kit with Two SAE to SAE Polarity Reverse Adapters

Product Information

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. 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. That way you can use less expensive wiring (such as THHN rated insulation) inside the electrical conduit to cover greater distances at substantially less cost than the MC4 cables. Our SVB experts explain how to use solar energy on your boat and help you find the right system for your vessel.

I cut off the ends of an heavy duty extension cord --- the female end, I attached that to the twistlock which goes to the camper. Easy to use, charge your solar with the adapter cable and for easily connecting to RV solar panels, suitable for most the solar panel kit. With this high-quality photovoltaic MC4 (standard4) connector set (male / female), the solar connector cables between the module and the controller can be set up as required. But I think for the amount of time I would be charging on the road, getting something over 13 volts to the battery in the field will be adequate. You can then strip back the insulation from the cut ends and terminate them to a bus bar or circuit breakers.When we increase current without increasing voltage there is a very good chance we will need a larger wire to avoid voltage drop from the parallel connection to the destination. 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. If you're only using two modules, or two strings of modules, the easiest method is to use MC4 multibranch connectors.

Take a look at the first module and you'll notice that it has two wires extending from the junction box. They plug-in either way so you need to keep track of the + - yourself when you're making the wires up to receive them. Finally, to prevent sea air and rain from corroding the electrical business ends, a compatible "grease" could be applied that wouldn't attack the rubber or plastic body of the connector but would keep the metal protected. That allows you to plug into both leads of your solar panel and it gives you plenty of wire to get to your destination. Unfortunately I don't think there is ever a perfect answer since it's impossible to know the exact future conditions you will find yourself in.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.

I have spent forever analyzing the pros and cons of all the choices involved, from panels to controllers to connectors to wire gauge, to how long an extension to run. 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. Systems using two modules are generally used for RV's and boats, so you can usually use the extension cables along the entire distance. 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.

Due to the locking mechanism of the MC4 connectors, they will not come unplugged and are well suited for outdoor environments. Supplied as a 10m length complete with male and female solar connectors terminated on the cable ends. 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. I've also read that energy loss is less a function of the connectors and more about distance and gauge of wire. 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.SAE connectors can get snug to seat fully, which is a good thing as opposed to being sloppy and sliding in easily. This allows me to use the same power cord I use for shore-power between my solar panel and my trailer. I tried this project with a lesser quality panel and the project failed because it wasn't efficient enough. Essentially, you've stepped down the number of wires from two positive and two negatives to one positive and one negative. Even though MC4 connectors appear to shield the actual electrical contacts when connected, when disconnected, those contacts are just as susceptible as SAE connectors to salt air, etc.
