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

Since I can easily swap the polarity when installing this is not a big issue but I will have to remember the connector/polarity of the cables will be reversed. Systems using two modules are generally used for RV's and boats, so you can usually use the extension cables along the entire distance. Do you have one or more high-performance solar modules and would you like to connect them to your solar controller as easily as possible? I'm sure people will have a fit when I say how I solved my wire problem between the panel and the camper.

Supplied as a 10m length complete with male and female solar connectors terminated on the cable ends. Yep, they're occasionally a bit finicky to get apart (and my fingers are definitely getting old) but not enough to make me wish I has something different. 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. The other consideration is the gradual loosening up of the pinch action as they are connected and disconnected repeatedly.They meet the requirements of the National Electric Code, they're UL certified and the preferred connection method of electrical inspectors. If not, I can still add the MPPT controller and just mount it to a board to be placed either in the galley or even propped up on the ground when charging. Storage of both the actual electrical connections, female and male types, are subject to corrosion and soiling. Over the course of a year, it will get charged much more at home where I can always get max charging. You no longer need the multibranch connectors because the combiner box will be performing the same function.

Just in case you need more to think about - you might consider not purchasing the solar controller with the panel and locating a controller in the trailer. I had the same concerns about the MC4 connectors but have been using them for 6+ years now without a problem. 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. 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.I tried this project with a lesser quality panel and the project failed because it wasn't efficient enough.
