Can't disconnect the XT90 plug from my AC200P

Just finished setting up and testing my AC200P with SP 120panels. Everything worked great, but I can not disconnect the XT90 connector. Any suggestions?

The XT90 connector is Yellow and just pulls apart from the piece it mates to. If you are referring to the aviation connector that is black and plugs directly into the AC200, you just pull the outer ring outwards and then the plug will release. The aviation connector locks onto the AC200 and the outer ring is the unlock feature.


Thank you! It was the aviation connector - I never noticed the outer “pull” ring. Still learning.
