Liquid-cooled generator naming conventions

Generac liquid-cooled generators follow a naming convention that indicates kW rating, engine type, voltage type, fuel type, and other information.

Environment

This information applies to Generac liquid-cooled home standby generators.

Determining generator characteristics using the model name

RG series

Example:
RG02224ANAX = RG | 022 | 24 | A | N | A | X

Segment	What it indicates	Common values
RG	Series	RG
###	kW rating	Example: 022 = 22 kW
##	Engine size	Example: 24 = 2.4 L
Voltage code	Voltage type	A = 120/240 V 1-phase G = 120/208 V 3-phase J = 120/240 V 3-phase K = 277/480 V 3-phase
Fuel code	Fuel type	N = Natural gas V = Propane vapor * = Field convertible to LP
Enclosure code	Enclosure material	A = Aluminum
Emissions / catalyst code	Emissions/catalyst configuration	X = No catalyst C = Catalyst and A/F ratio

Using the example above:

• RG = Series
• 022 = 22 kW rating
• 24 = 2.4 L engine
• A = 120/240 V voltage rating
• N = Natural gas
• A = Aluminum enclosure
• X = No catalyst

QT series

Segment	What it indicates	Common values
QT	Series	QT
###	kW rating	Example format: 045 = 45 kW
##	Engine size	Example format: 68 = 6.8 L
Voltage code	Voltage type	A = 120/240 V 1-phase G = 120/208 V 3-phase J = 120/240 V 3-phase K = 277/480 V 3-phase
Fuel code	Fuel type	N = Natural gas V = Propane vapor * = Field convertible to LP
Enclosure code	Enclosure material	S = Steel A = Aluminum
Emissions / catalyst code	Emissions/catalyst configuration	X = No catalyst C = Catalyst and A/F ratio

Diesel models (RD series)

Example:
RD02023ADAE = RD | 020 | 23 | A | D | A | E

Segment	What it indicates	Common values
RD	Generator series (diesel)	RD
###	kW rating	Example: 020 = 20 kW
##	Engine size	Example: 23 = 2.3 L
Voltage code	Voltage type	A = 120/240 V 1-phase G = 120/208 V 3-phase J = 120/240 V 3-phase K = 277/480 V 3-phase
Fuel code	Fuel type	D = Diesel
Enclosure code	Enclosure material	A = Aluminum
Tank code	Fuel tank configuration	E = Standard fuel tank L = Long run tank

Using the example above:

• RD = Generator series (diesel)
• 020 = 20 kW rating
• 23 = 2.3 L engine
• A = 120/240 V voltage
• D = Diesel fuel
• A = Aluminum enclosure
• E = Standard fuel tank

XG series

XG series liquid-cooled standby generators use a similar naming convention format.

Example:
XG04845ANAX = XG | 048 | 45 | A | N | A | X

Segment	What it indicates	Examples
XG	Series	XG
###	kW rating	032 = 32 kW, 040 = 40 kW, 048 = 48 kW
##	Engine size	45 = 4.5 L
Voltage code	Voltage type	A = 120/240 V 1-phase C = 3-phase (model dependent, such as 208/240 or 208/240/480)
Fuel code	Fuel type	N = Natural gas (XG models are typically configured for natural gas and liquid propane operation)
Enclosure code	Enclosure material	A = Aluminum
Emissions / catalyst code	Emissions/catalyst configuration	X = No catalyst C = Catalyst / EMS configuration (model dependent)
