Converter Size and Generator Size, Etc
Some useful info here about choosing converters and what generator needed in the Q and As, plus some example specs. Although it is for boats, much of it also applies to RVs (they don't explain VA an...

The PowerMax figures will be in the revised spec sheet, but meanwhile:
I can report (again :) ) that my Honda 3000 at sea level can do 130 DC amps worth of Vectors ( PF unknown) but at 135 amps it pops its breaker. Substituting the PowerMax 100 amper (PF corrected) for some Vectors, the Honda can now do about 160 amps before popping its breaker, and it has also now run the 100 amper plus the PM3-55 non-PF without popping its breaker doing 156 amps.
I tried to figure out the PF of the Vectors a while back using that information, but I am not claiming any accuracy.
Honda VA limit rated at 2800VA. 130 amps non-PF and 160 amps with 100 PF, 60 non-PF. So the 60 non-PF is the same, but the 100 PF is only 70 when not-PF corrected. So the Vector PF is 0.7 ?
The 2800VA can do 130a of 0.7 PF charger so it ought to be able to run 100/70 x 130 = 186a worth of PF corrected chargers at sea level
If 186a size = 2800VA with PF at 1.0, then a 100a charger should be rated at 100/186 x 2800 = 1505 watts
A 55a charger should be rated at 55/186 x 2800 = 828w, (the PD9260 says 1000w input) then with its 0.7 PF it should require a supply of 100/70 x 828 = 1183VA
Since actual specs for the various brands of converters are a little different, there must be some errors in my approach.
- the actual Honda VA vs that 2800 as rated.
-the 100a PF corrected charger is not at 1.0 but at 0.9x PF
But it is all sort of somewhere in that general amount more or less approximately.
