Term Definition
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

is not
available for use
On-grid Utility grid power is available for use (does not imply grid-interactive capability)
PV Photovoltaic
RE Renewable Energy
RTS Remote Temperature Sensor; accessory that measures battery temperature for charging
Slave An inverter which adds additional power to the master or subphase 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 that typically carry 120 Vac with respect
to neutral and 240 Vac with respect to each other; common in North America
Subphase Master An inverter which provides the output for additional phases of a stacked system; the phase
of a subphase master is based on the output of the master
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
Turbo Fan External cooling fan used in place of the DCC on sealed FXR inverters
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
