Abbreviation / Definition
Energy is measured and reported by the 1500kW inverter in Wh (Watt hours), kWh (kilowatt
hours), and MWh (megawatt hours) for both the PV (DC) input and the AC (grid/utility) output.
A conductor used to connect the system grounded conductor or the equipment to a grounding
electrode or to a point on the grounding electrode system.
The grounding electrode conductor(s) forms the continuous, unbroken, ground reference of all
non-energized metal components compromising the PV array, the S-Max inverter, and the
B.O.S components up-to and including the point of common coupling (electrical panel / utility).

ground connection.
grounding electrode or electrodes.
e.g., a ground-rod or similar.
Operation is in parallel with an existing electrical network, supplying common loads and
sometimes delivers power to the utility/grid. The technical name for a grid-Tie or grid-tie
inverter is a "utility-interactive inverter" and is designed to operate only when the utility
grid is present (i.e., anti-islanding). Grid Tie inverter will be abbreviated with GTI.
Units are Imperial or English; inch, foot, pound, versus SI units.
Soft conversion to SI, as per the NEC 90.9
document. Note: See Torque in this glossary.
The basis or core-function of a grid-Tie inverter, solar-inverter, or utility-interactive inverter. Also
referred to as a grid-tie inverter.
production and distribution network.
e.g., Inverter's DC circuits connected to the PV Array
another electrical power production source, such as a utility, for electrical production and

3-phase AC circuits connecting to the point of common coupling (PCC)
Infrared light is electromagnetic radiation with wavelengths longer than visible light. Uses
include remote temperature sensing.
Standardized system of wire sizing for conductors larger than AWG 4/0. A circular mil equals
the area of a wire one mil in diameter, or 1/1000 of an inch (1000 mils = 1-inch diameter). MCM
is an older abbreviation for "one thousand circular mils" and is equivalent to kcmil used in the
NEC. For a metric equivalent of area in thousands of circular mils, 1 kcmil equals 0.5067 mm
