Term Definition
12V AUX Auxiliary connection that supplies 12 Vdc to control external devices
AC Alternating Current; refers to voltage produced by the inverter, utility grid, or generator
AGS Advanced Generator Start
CSA Canadian Standards Association; establishes Canadian national standards and the Canadian
Electrical Code, including C22.1 and C22.2
DC Direct Current; refers to voltage produced by the batteries or renewable source
DVM Digital Voltmeter
FCC Federal Communications Commission
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/Hybrid ™ System technology which optimizes both grid-interactive and off-grid options
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
HBX High Battery Transfer; a function of the remote system display
IEEE Institute of Electrical and Electronics Engineers; refers to a series of standards and practices for the
testing of electrical products
IEC International Electrotechnical Commission; an international standards organization
LBCO Low Battery Cut-Out; set point at which the inverter shuts down due to low voltage
NEC National Electric Code
NEU AC Neutral; also known as Common
Neutral-to-ground
bonding 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
RELAY AUX Auxiliary connection that uses switch (relay) contacts to control external devices
RTS Remote Temperature Sensor; accessory that measures battery temperature for charging
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
System display Remote interface device (such as the MATE3), 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
Utility grid The electrical service and infrastructure supported by the electrical or utility company; also called
“mains”, “utility service”, or “grid”
