Don't buy your renorgy panels or accessories for renorgy. I bought a small adapter, was offered a 5% discount code,that didn't work. Then they charged me $10 extra for shipping a plug that fit in an envelope. I should have bought it from Amazon. I would have saved the $10 shipping. When I asked why I didn't get 5% off, they offered me $.85. Buy anything you need from Amazon.

Its a connector

The negative wire is marked red and I did not notice soon enough. I had the solar panel plugged in reverse polarity because of this confusion. I understand that the adapter can be used to convert from solar to SAE and also convert from SAE to solar; since it is designed that way it should not be marked red for positive.

I had to reverse the mc4 connectors so they would connect to my 50' cable assembly.

Did not work with Jackery.

They will do exactly what I needed to insure that batteries stay charged!!👍😀

Already posted a report with no response. Company has terrible Tech Support. Never received email I was told they would send to help me. I feel who ever you are reviewing this, it's not getting to the people who can FIX my issue.

This is the perfect fit!

Exactly what I wanted for my exterior connection on my RV. Shipping was great.

It works well. As a matter of fact, Im going to buy more.

Your connectors are difficult to disconnect. May be my fat fingers.
Had to cut/ grind away some plastic around release button to make them functional.

Works as described!
