Itinerant1,
The generator can do 13.3 but may also do a small over load for 30 minutes. By then the draw from it may have dropped to below the 13.3 threshold.
From the numbers on the ARC display:
125 x 13.5 = 1687.5 watts
1687.5 / 120 = 14.06 amps
I see from the display that the Magnum is being run in load support mode.
Was solar contributing amps to the battery bank?
Pianotuna, you got me thinking about the Magnum/ Honda 2000 charging so I emailed Magnum tech support and sent the pics and this was his response.
The MSH3012M will charge at 125 amps using 18 amp max from the generator. So in your case the charger is probably turned down some so as to not over load it and you are probably charging at about 100 amps.
So if you crunch the numbers you are getting a little more than 13 amps out of generator or we are a little more efficient than our specifications and we aren’t using a full 18 amps for 125 amps dc.
18 amps max / 15 amps which you have it set for = 83%
.83 X 125 amps dc = 104 amps
So he was close with his numbers but a little off, our display is showing 125 amps but the starlight display is showing 100 amps. Our home screen amps in not the most accurate in can be +/- 20% because it is a calculation, I would trust our battery monitor kit or the start light more for amps so it should look like this.
100 amps x 13.6 DC volts = 1360 watts
1360 watts / 120 AC volts = 11.33 amps
So 100 amps for two hours will raise the ah from 255 to 455.
