Howdy Mark. I suspect the amount of current it provides will be dependent on the load at any instant in time. I can't remember if i have ever measured while the inverter was on. (I doubt it though) I would expect the current OP from the alternator would jump up if the inverter was on....even on idle. Yes...No??? Thanks in advance.

Most alternators will put out at least 1/2 max output at idle or more.
I just now went out to my old 99 tahoe with a 140 amp output max and checked it at idle with a clamp on amp meter just for this thread.
Yes I have a slightly smaller pulley ( because I need it and know wtf I'm doing ) and it puts out 121 amps at IDLE. Idle is 650 rpms plus the smaller pulley would net about 850 rpm in comparison for a stock vehicle. It is an OEM junkyard used alt I got on eBay to upgrade the stock 100 amp I had.......needed more for my Efans.
