I re-read post 20 carefully. I didn't list any numbers. You wish to compare to north of $16K for the hardwired version, then attribute the number to you. A number you can attribute to me for a wild rectum guess is south of $10K
You said that for the same price as a the 100A feeder the customer could afford 2.4 kW of solar. I assumed you were using my $7/w figure (you asked me for a figure and then quoted my answer when you said that.). 2.4kW times $7 is $16,800. I'm not going to hold you to any number, but that's where I got it from.
The case that started this thread may not be a good example, but there are certainly going to be cases where solar is cost effective. Let's just say that instead of 600ft, it was 2000ft, or a mile. The equation eventually tips.
wesserl, the system would handle the torque from any motors just fine as long as the surge capacity of the inverter is in spec. As I mentioned, the system I linked to has 6000VA momentary surge. I would trust it with any 110V power tool. Now if you actually need 240V, you'll need stacked inverters, and it would be more expensive.
