My setup:
2-G29 12V batteries (next time it'll be dual GC-2's)
IOTA 55A deck-mount converter mounted in the pass-through.
The factory WFCO charge circuit is disconnected since it never goes into boost mode.
Honda 2000i generator.
The Honda handles the IOTA when the IOTA is putting out its full 55A. And DW can run her hair dryer and make perked coffee, just not all at once. I like to get an hour a day on the generator just to top off the batteries. The Honda has also served to run my house fridge, furnace, sump pump, TV, and a few lights during power outages, the latest one last week during the windstorm in NY.
Using the battery charger output on a Honda is the most inefficient way to charge a battery.
To do over I'd still get the 2000i. I don't think a 1000i would run more than a 30A converter at full output.
