all units have similar run times of between 35 and 40 percent at 70 degree ambient temp.

what i am in reference to is run capacitors and not start capacitors.

all of my inverters, modified sine or rather modified square wave units will start and run capacitor start and capacitor run motors, without problem.

yes pfc is done to cover the magnetizing component, which in some cases is as much as 60 percent of the total power that has to be delivered to the motor before any useful work is done.

i am aware that the power company doesn't charge me for poor power factor in my home, but rather an average with there meter, (cheaper for them).

but the fact remains that if i am the power company, i still maintain that it is in my best interest to incorporate pfc in my system.

the funny thing is pfc is so poorly understood by so many people,including many so called electrical experts,  i have heard everything from...

1. "just run larger wires to accomodate the line losses caused by poor power factor", problem here is you havent corrected anything but rather backed the problem up to the point of generation.
2. "you can't use pfc on systems with inverters", which is not the case with fixed frequency inverters such as we use, but rather motor speed control inverters used by industry which regulate the motor speed by varying the frequency to the motor.
3. and my favorite "why do it when the power company doesnt currently charge the residential user for poor power factor" i love this one because this answer comes on the heals of my stating that i am my "own power company", and as such i have to produce the extra power to provide the magnetizing current.

i maintain that pfc by means of capacitors are far cheaper and easier than additional fuel for a generator, larger windgenerators, larger inverters, larger pv panels, etc. etc.

if it works for industry, it stands to reason it would work for tha standalone power system, albeit the decimal point moves over a bit.
