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

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. I tried this project with a lesser quality panel and the project failed because it wasn't efficient enough. 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. The two 170W flexible panels fit well on my Bimini and now I generally don't bother hooking up to shore power.

Over the course of a year, it will get charged much more at home where I can always get max charging.You obviously can't connect two male connectors or two female connectors together, so we use the multibranch connectors to accomplish that. I have never had problems with my SAE connectors, but I have helped fellow campers to set up and crack down and I hate MC4 connectors. 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. Would animal pee, an errant cup of coffee, or a little drizzle when you’re away from camp short the system? Systems using two modules are generally used for RV's and boats, so you can usually use the extension cables along the entire distance.

They plug-in either way so you need to keep track of the + - yourself when you're making the wires up to receive them.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.

That allows you to plug into both leads of your solar panel and it gives you plenty of wire to get to your destination. This solar connector is used to connect the mc4 plugs of all our solar panels to a compatible SAE camper van connection.If you connect two of them in parallel, your total amps would be 16 amps Imp and the voltage would remain at 18 volts Vmp. only one trip in slushy road salt was enough to degrade the connections, to raise resistance and blow the battery fuse switch repeatedly even tho the CTEK only draws 6a for vehicle charging on CI house battery. When you use solar panels on a house or cabin, the distance that the wire must travel is normally so long that using an extension cable is no longer practical. 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. 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.
