I have seen 16 amps going to the house bank at idle. The highest reading noted was 19.6 amps, when driving. I don't have an easy way to measure input amps to the unit.
I keep thinking about this.
It is possible that the charger is limiting the output current when there is lower input voltage because of internal heat. In other words, it is protecting itself from over heating.
Hi theoldwizard1,
I don't know the input voltage at idle. It is not something I would normally do (i.e. idle).
