120A max charge current. At the moment it flips out, it is less than half that. Here are some images of an example when it struggled keeping the AC on. At just past 14:30 is when the AC compressor comes on, then a few seconds later it throws code 12 (charge current over). You'd think that it would immediately trip with the compressor comes on, but it is several seconds after it is running just fine. If the sun is not out, or the batteries are full and not charging, no problems at all.
