Inverter/converter vs stand-alone units: lots of questions

Another point is that an inverter charger may almost certainly be a lot more costly than a stand alone unit with a good quality converter.

The other issue is that if you rely on only the inverter charger and it fails on a trip--the trip may have to end.

If cost is no issue, then look for a hybrid inverter/charger from Victron or Outback. Hybrid = load support which is quite useful. Even on a 30 amp pedestal I can use over 30 amps with the excess power coming from the battery bank.
