Yeah Doug, that's a tad out of the range of a portable generator
I don't have a daily draw on my Irwin yet (too new to me). On my Gemini we managed to just barely fall short with a single 80w and 210ah of AGM's, making 35-40 and using 45-50 a day.
My goal was three days of hang time, then motoring out of the anchorage, into the next caught me up to 100%. It worked.
