Jackery 3000 Pro simultaneous A/C Charge/Discharge

Has anyone tested A/C charging the Jackery 3000 pro while pulling more than 1500w from the 25A port? I'm considering purchasing one partially for home backup with a transfer switch and trickle charging it from my truck. I know the bypass mode is limited to 1440w per the manual, but it's not clear what happens if the AC out exceeds that while charging.
