Why go solar?
Why go solar if generator/propane is still a must? After looking seriously at fitting rv (when we get it) with solar I am beginning to realize that solar cant keep up with what I want it to do. I want...

Hi BFL13,
Actually the Magnum inverter/chargers can do 125 amps @ 12 volts from an 1800 watt shore power supply--so they should be able to do that from a 2k generator.BFL13 wrote:

I would like to know how this could be done. I can't get the numbers to work.
I believe a 2000w gen can't run a 100 amp charger that is PF corrected, but it can possibly run a 75 amp non-PF corrected one.
My PF corrected 100 amper powered by my Honda 3000 showed this on the Kill-A-Watt (which maxed the KAW so I was lucky it didn't fry)
(loaded voltage showing of course):
122.7v , 15.57 a , 1854w , 0.97 PF , 1910va. Output was DC 102a with batt at 13.95v, charger set to 14.8v.
Scale that up for 125 amp DC output, you would expect say, 2385va with loaded voltage a bit lower, say 120v and so 19.88 amps
The question is how was he able to that with a Honda 2000 generator rated 13.3 amps? My thought is he had something wrong with his monitoring information, leading him to think he was doing that. If he actually was able to do it, I still would like to know how.
I doubt it could be done on shore power on a 15a circuit either, but I don't know what a 15a circuit breaker can take before it pops.
