Term Definition
12V A
UX
Auxiliary connection that supplies 12 Vdc to control external devices.
AIC Ampere Interrupting Capacity; the rated current a circuit breaker can interrupt without
damage
AGS Advanced Generator Start
Communications
manager
Multi-port device such as the OutBack HUB10.3, used for connecting multiple OutBack
devices on a single remote display; essential for stacking inverters
CSA Canadian Standards Association; establishes Canadian national standards and the
Canadian Electrical Code, including C22.1 and C22.2
ETL Electrical Testing Laboratories; short for the company ETL Semko (Intertek);
refers to a certification issued by ETL to OutBack products indicating that they meet
certain UL standards
GFDI Ground Fault Detector Interruptor; a safety device for PV systems
GND Ground; a permanent conductive connection to earth for safety reasons; also known as
Chassis Ground, Protective Earth, PE, Grounding Electrode Conductor, and GEC
Grid-interactive,
grid-intertie, grid-tie
Utility grid power is available for use and the inverter is a model capable of returning
(selling) electricity back to the utility grid
GSLC GS Load Center; the wiring box for the Radian (GS) inverter
IEC International Electrotechnical Commission; an international standards organization
Invert, inverting The act of converting DC voltage to AC voltage for load use or other applications
Master An inverter which provides the primary output phase of a stacked system; other stacked
inverters base their output and on/off state on the master
NEU AC Neutral; also known as Common
Neutral-to-ground
bond
A mechanical connection between the AC neutral (Common) bus and the ground (PE) bus;
this bond makes the AC neutral safe to handle
Off-grid
Utility grid power
is not
available for use
PV Photovoltaic
RE Renewable Energy
R
ELAY
A
UX
Auxiliary connection that uses switch (relay) contacts to control external devices.
RTS Remote Temperature Sensor; accessory that measures battery temperature for charging
Slave An inverter which adds additional power to the master in a stacked system; a slave does not
provide an output of its own
Split-phase A type of utility electrical system with two “hot” lines 180° out of phase, common in North
America; each line typically carries 120 Vac (or the nominal line voltage) with respect to
neutral and 240 Vac with respect to each other
System display Remote interface device (such as the MATE3s), used for monitoring, programming and
communicating with the inverter; also called “remote system display”
Three-phase,
3-phase
A type of utility electrical system with three “hot” lines, each 120° out of phase;
each carries the nominal line voltage with respect to neutral; each carries voltage with
respect to each other equaling the line voltage multiplied by 1.732
UL Underwriters Laboratories; refers to a set of safety standards governing electrical products
Utility grid The electrical service and infrastructure supported by the electrical or utility company;
also called “mains”, “utility service”, or “grid”
