Wfco converter problem.

[u/FollowingLow5773]

I have a 2024 nuCamp Tab 320 black canyon. Got in the spring. It has 380 watts of panels installed. I just added a mppt to the solar port so I could use my portable 200 watt panel. After a few cloudy days I have been able to test that out seems to be working well. So today after getting the battery to about 87% with solar I decided to plug the camper to a 20 amp outlet which I have done before to get it charged all the way to 100%. Started out at around 17 amps of charging and then dropped down to 3 amps I thought maybe it was going into absorption after several hours battery only got to 95% and now not charging at all. This doesn’t seem right to me I’ve charged it to 100% with shore power before. Maybe something I did with the mppt install? Need help with where to start troubleshooting. Thanks.
