The electrical power of a system.Energy is measured and reported by the 1500kW inverter in Wh (Watt hours), kWh (kilowatthours), and MWh (megawatt hours) for both the PV (DC) input and the AC (grid/utility) output.GEC . . . . . . . . . . . . . . . . . Grounding Electrode ConductorA conductor used to connect the system grounded conductor or the equipment to a groundingelectrode or to a point on the grounding electrode system. 1The grounding electrode conductor(s) forms the continuous, unbroken, ground reference of allnon-energized metal components compromising the PV array, the S-Max inverter, and theB.O.S components up-to and including the point of common coupling (electrical panel / utility).GFDI . . . . . . . . . . . . . . . . .

Connected (connecting) to ground or to a conductive body that extends theground connection. 1Grounded Conductor . . . . A system or circuit conductor that is intentionally grounded. 1Grounding Conductor . . . . A conductor used to connect equipment or the ground circuit of a wiring system to agrounding electrode or electrodes. 1Grounding Electrode . . . . A conducting object through which a direct connection to earth is established. 1e.g., a ground-rod or similar.Ground Fault . . . . . . . . . . The unintended flow of electrical current to groundGrid Tie Inverter . . . . . . . . An inverter that converts direct-current electricity into alternating-current electricity.Operation is in parallel with an existing electrical network, supplying common loads andsometimes delivers power to the utility/grid. The technical name for a grid-Tie or grid-tieinverter is a “utility-interactive inverter” and is designed to operate only when the utilitygrid is present (i.e., anti-islanding). Grid Tie inverter will be abbreviated with GTI.IGBT . . . . . . . . . . . . . . . . . Insulated Gate Bipolar Transistor (Inverter’s semiconductor switching device)IMCS . . . . . . . . . . . . . . . .

A circular mil equalsthe area of a wire one mil in diameter, or 1/1000 of an inch (1000 mils = 1-inch diameter). MCMis an older abbreviation for “one thousand circular mils” and is equivalent to kcmil used in theNEC. For a metric equivalent of area in thousands of circular mils, 1 kcmil equals 0.5067 mm2 .
