NEC Article 690 specifically addresses solar photovoltaic systems. The sizing process involves calculating the maximum circuit current and then applying adjustment factors. Alternating current (AC) flows in both directions, going from “0” to “120 volts”, then reversing direction, dropping back to “0” and increasing to “120 volts”. This cycle is repeated 60 times per second (hertz). Voltage is like water pressure in a pipe. Here's. . The load is calculated by enumerating all appliances together with their power ratings and operational hours, thereafter adding these values to derive the total average energy demand in watt-hours or kilowatt-hours. It is preferable to enumerate both AC and DC loads individually, as inverter sizing. .
