I do not think that PF correction is useful in a domestic situation. Make a list of all the inductive power consumers in a typical house, typically motors, A/C units, freezers, fridges, fans, turbo heaters, some washing machines, solenoids in HVAC kit, CH pumps and well pumps and some wall wart power supplies. Most TVs, radios, PCs, washing machine motors - most modern devices have SMPSs in and so are actually capacitive in their own right. Only the first three items on my list have motors that consume any power, typically 1 KW between them and that only when they run. So if their PF is .8, i.e. ~200 W of inductance, you need 200W of capacitance to offset it, so when they are all on, you have unity PF, as they go ofF (A/C at night?), you are consuming 200 W of capacitive current, i.e. an extra 200/230 A which is flowing through your wiring for 15 Hrs/day as opposed to the same current flowing due to the inductive losses for the 9 Hrs/day. Because fridges and freezers run for much less then 15 Hrs more like 4 Hrs, and A/C units only for 12 Hrs, the capacitive current/Hrs are much greater then the Inductive current hours. Oh, that also presumes that the capacitance has been "tuned" to the specific units.
Don't bother, unless you are clever enough to switch in the correct amount of C at the correct time.
