At a typical 80% efficiency and 0.7 power factor, a maxed-out 60 amp converter will draw over 1,500 VA, and a maxed-out 75 amp converter over 1,900 VA. You can get away with higher than 60 amps on an eu2000i if you're willing to make sure the battery doesn't get highly discharged, cut other loads when necessary, and/or manually kick the converter out of boost mode when necessary. If you really need the bigger converter, a power factor corrected model might be justified.
Thanks . . . . good info. I am not sure, but I think that you are saying to get the 70-75 amp converter.
How do I manually kick out the boost mode on a converter? Is that a special option on some converters?
We don't boondog much, but I have a Harbor Freight 3000 generator, and I plan on doing some boondogging where I will need to use the generator.
I went through Bend 40 years ago, and fell in love with it. I remember one gas station and one diner. A guy at the diner said he shot a buck off of his porch. I returned to Bend 15 years later, and decided to look elsewhere.

The PD "Progressive Dynamics" product line is the only moderate cost converter that provides this ability. In my and many's opinion one of the best features avail for charging our batteries.
Sometimes when one starts charging and the batteries are cold they will cause all converters to not go into Boost/bulk mode. Thus charging will be slow. If one has the PD with the controller he can switch modes to bulk by pushing a button.
Another is if you have a big battery bank and a high amp converter 60+ and are trying to charge using a smaller genny you can switch modes to a lower charge rate, ABSORB or Float until the batteries have charged enough to allow the higher charge rate of bulk mode.
Another is when your batteries are hot 95deg+, because of hot weather . You do not want to charge very long in bulk mode with any converter. The PD allows you to switch modes to a lower setting and thus not boil your batteries.
