I've noticed that running my generator with only the batterycharger on that the AC amps are 6, but the DC amps going into my battery per the battery monitor is only about 30. So that's 690W being supplied to the charger, but only around 420-450W going into the battery.
Can anyone explain where the extra watts are going? The charger power factor is 0.89
stop blowing smoke up my rear, blow it at the sails instead
My generator right now is supplying 9.2 amps at 115 VAC, the battery charger is putting out about 47 amps at 14 VDC.
Is this normal for a battery charger? I don't have any experience with the battery charger except recently with the generator.
That's only about a 60% conversion efficiency which isn't very good, but it is what it is. I would expect to see something in the 80-85% range for a charger, but clearly it's not a big priority for designers.
