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.
24 hours at 114 watts = 2,736 watts or 2.7 kwh/day
2.7 X $0.175 X 30 = $14.175
Which is worth saving. Even half that would be okay, as I already own the solar equipment.
Our park has that good electricity at $0.175/kwh, not that cheap stuff that most parks provide. (Sarcasm off)
