Converter Consumption
I know that there is no such thing as "Average usage", but has anyone measured how much electricity is required to operate their converter? My guess is about one kilowatt per day. I can charge my hou...

Say your average DC amps is 5 at 13.6 volts all day. That is 68 watts. Efficiency is 85%, so input watts is 80 watts. Converter has PF of 0.7, so VA required is a steady 114.3 VA. Call it 1 AC amp at 115 volts.
Whatever that is in kw, for an hour is your kwh.
It is unnecessary to apply the power factor in this case; the electric company charges you for kWh, the actual energy used, and not kVAh. In the example, it works out to just shy of 2 kWh each day.
(For large commercial/industrial accounts the power factor is taken into account, along with peak usage and other such things...but not for residential users, at least anywhere that I've heard of.)
