Hmm, isnt everything *new* and larger than x Watt or so made to have a PF of 1 nowdays? a Rule/Law? (At least in Europe ) As far as I know everyone also do have Reactive-blink LED +the normal kWh Blinker on the meter, but i think the power companies just remote-monitor the consumers now, so no charge for the losses (yet..), industrial customers pay and many compensate locally (capacitors) for bad PF, to be able to save money, but also to be able to increase the output at the site, I assume. In the US it might even save more from resistive losses, if they did it right? As you have so very low voltage lines. > > I think a better solution would be to make a charger that *compensates* > for the power factor of the home as a whole. That is, since most home Yes. I think we can do that here with the solar inverters if we like to. Make them produce "Capacitive" power :-) But as no one yet get charged on individual level there is not many asking for this. But some do. Lee: if I use an Async motor to generate power to the grid (Like in a small vind turbine, by overspeeding the motor it runs as a generator) But will that still be reactive power("inductive") The current is on "the other side" of grid wave now, ..i assume, as it tries to increase the grid frequency, or? .. Hmm I feel that i'm a bit out of phase here :-) /John -------------- next part -------------- An HTML attachment was scrubbed...
