I've got the VFX 3524 inverter which, yes, has a charger built in. I've taken readings in the past and the power factor is pretty darned close to 1.0, maybe 0.98. It would be pretty silly to junk a $1750 charger inverter because it's 0.02 off, don't you think?
I only have one inverter, which is all I need, but it means that I can't get 240v. I have to run the genny at 120v. Since the genny is 3000 watts (a little less actually), I can only draw 1300 watts before tripping the breaker. Now, if I can wire the generator to achieve full output at 12 amps, that would allow me to draw slightly more than 2500 watts, which would be okay. That would mean the batteries could be charged or equalized more quickly and I would save fuel.
So, anyone have any ideas about the wiring?
