Many utilities charge extra, calculated in various ways, when the PF falls below certain limits such as 90%. These surcharges do not apply to residential users, but only to some/many commercial and industrial users. In the amount of low PF power we're talking about here, in a UPS, it is tiny and inconsequential. Laryn K8TVZ
