you should be fine as long as the alt has good cooling. the standard number is 25 % of your bank, which would be 75 amps. if you run you batteries down to 50 % or 150 amps, it would take 2.5 hours to fully recharge if it was a perfect system. but do to reasons of the way batteries charge it might take 5 hours to fully charge. figure in 2 hours you could put in about a 100 amps ( if alt cooling up to par ) which is close to the real normal range of 70 to 80 %.
so yes it should be okay if you have good alt cooling, maybe even a vent tube going to the alt
