boB,
Not only does that make sense, it's the best explanation of the effect of power
factor on an off-grid system that I've read.
I would than assume that this means that Drake's refrigerator is actually
consuming more power from his battery system than is just measured in AC watts

Thanks all.
It was my understanding that we should still be running the conductors
of the same circuit through the same raceway, even if it is the DC input
into the inverter since that DC oscillates slightly (nowhere near as
much as AC). I wasn't concerned about eddy currents in the FNMC of

Esteemed Wrenches,
We haven't talked oscilloscopes since 2007. We have a Nantucket Fronius
inverter that is telling us there is an AC frequency problem. It seems
feasible that there is a frequency issue way out there and that we better
check that.
Any reviews on the Velleman handheld (or any
Seems that if it is only frequency you are looking for, a simple Fluke with
min/max capture is all you really need (of course it must measure
frequency).

This might sound really stupid, but double check to make sure you have AC
power to the inverter input terminals. I'm working from memory here, but I
think I remember Brian Farhi saying that the Fronius inverter first looked
for frequency before voltage, and no AC present will throw a frequ
