Solar connector corrosion

The solar wasn't providing any power on my 2015 Ext. and I found a corroded connector up there. Any suggestions for a different fitting are appreciated, the original fitting is positioned to collect water corrode.

I've had trouble finding one narrow enough to fit in the space. I just replaced the existing connector with the same thing that Airstream used and buried it under a bunch of eternabond tape. It hasn't leaked in four months, so far. Rain season is just beginning now. Time will tell.

MC4 connectors are the industry standard. They have O-rings to seal out moisture and are generally about $2 a pair. Amazon has an SAE to MC4 breakout cable if your space is limited.

Thanks LB. Based on the first picture in my original post, it looks like I have an SAE to MC4 at the roof entry and then two MC4 connectors to the solar panel wires. Once I get up there and remove the existing Sikaflex maybe there will be enough slack in the wires to just use a pair of MC4 connectors and seal the hole.
