Abbreviation / Definition
Typically a sinusoidal waveform (i.e., pure, quasi, or stepped)
An organization, office, or individual responsible for enforcing the requirement of a code or
standard, or for approving equipment, materials, an installation, or a procedure.
Standardized system of wire sizing, from Number 40 (small diameter) to 0000 [4/0]
(large diameter). Larger diameter wire is given in kcmil.
Example: The components required to complete a solar system, beyond the photovoltaic
modules and inverter, consisting but not limited to the PV array support structure, combiner
boxes, fuses, conductors, electrical conduit, DC and AC switch gear, and monitoring systems.
A message-based protocol for high-speed fault-tolerant communication and control. Originally
for automotive usages (Robert Bosch GmbH, 1983), now common for aerospace, medical, ad
industrial controls.
An automatically operated electrical switch designed to protect an electrical circuit and
equipment from damage caused by overload or short circuit. When used in solar
applications they shall be designed for backfeed or bidirectional operation, without reference
to Line or Load.

that allows electricity to pass along or through it. Conducts electrical current in an intended,
designed, or controlled manner Typically, wires and cables are insulated.
A non-sinusoidal waveform
A type of 3-phase transformer without a neutral (central) connection.
Described herein is the Power Xpert Solar 1500 kW Grid Tie Inverter 250 kW Solar Grid Tie
Inverter.
The conductive path installed to connect normally non-current-carrying metal parts of
equipment together and to the system grounded conductor or to the grounding electrode
1
conductor, or both.
Designed for photovoltaic (PV) applications and systems which require source-circuit or PV
output circuit (array) combining, overcurrent protection, and some means of disconnect.
Eaton product designed to be placed in circuits between the PV source and the inverter or
recombiner. Incorporates the Eaton DC disconnect acting on the combined circuit's (single)
output. See: www.eaton.com/solar
