I have a 100amp and 75 amp PowerMax. According to my Kill-A-Watt, the 100 amper pulls 1910VA when set to 14.8v and doing 103 amps.
Of course you actually use battery voltage at the time to measure your output watts, so peak input is just before DC amps start to taper down from 103 when the battery just reaches 14.x volts. (there is voltage drop at 103 amps, so battery voltage is not yet 14.8--more like 14.3 with my wiring zoo). You see the 14.8 at the end when amps are way down.
Gets sort of complicated what the max input would ever be. Anyway too much for a "2000w" inverter/gen, but ok for a "3000w" inverter gen. Don't know about in-between those size gens, such as a "2400w".
I can just run the 75 amper on my B&S P2200 at its 1700VA doing 75 amps, set to 14.8v. The gen is way maxed out but does not quit. Right on the edge.
I use #4 from the converter to battery. I think #6 would not quite do it and get full amps.
