Obviously this is a very broad calculation due to the fluctuation of electricity usage, but we used it to come up with a simple approximation of our DC’s power usage.
Example:
23,360 kWH / 30 days / 24 hours = 32.44 kW
32.44 kW x 1000 = 32440 Watts
32440 W / 0.9 (pf) = 36040 volt-amps (VA)
36040 VA / 240 V / 1.732 = 86.7 Amps
