I believe you mis-heard what he said or he mis-spoke.
The converter can supply (depending on model, camper demand, and wire fusing) anywhere from 30 to 60 amps of charging amperage during BULK charge mode. That is plenty for even the largest banks.
NORMALLY, BULK (battery BANK capacity LESS than about 50%) only lasts a few minutes to an hour and the initial battery voltage is high enough to require only 20 - 25 amps in that mode.
In reality, your battery bank would have to be completely dead for full rated charging amperage to be needed and may be interpreted by a converter as a dead short and prevent the converter from powering up at all (or a fuse could blow).
THAT may be what he said; but that is also true for large 12 volt banks as well.
