GENERAL SAFETY RULES
SAFETY
Never use the inverter in a location that is wet or damp. Never expose the inverter to rain, snow,
water spray or standing water while in use. Protect the inverter from all hazardous weather
conditions. Moisture or ice can cause a short circuit or other malfunction in the electrical circuit.
Never operate the inverter in an enclosed area. Engine exhaust contains carbon monoxide.
Only operate the inverter outside and away from windows, doors and vents.
DANGER
WARNING
WARNING
WARNING NOTICE
Voltage produced by the inverter could result in death or serious injury.
• Never operate the inverter in rain or a flood plain unless proper precautions are taken to avoid
being subject to rain or a flood.
• Never use worn or damaged extension cords.
• Always have a licensed electrician connect the inverter to the utility circuit.
• Never touch an operating inverter if the inverter is wet or if you have wet hands.
• Never operate the inverter in highly conductive areas such as around metal decking or steel
works.
• Always use grounded extension cords. Always use three-wire or double-insulated power tools.
• Never touch live terminals or bare wires while the inverter is operating.
• Be sure the inverter is properly grounded before operating.
Gasoline and gasoline vapors are extremely flammable and explosive under certain conditions.
・Always refuel the generator outdoors, in a well-ventilated area.
・Never remove the fuel cap with the engine running.
・Never refuel the inverter while the engine is running. Always turn engine off and allow the
generator to cool before refueling.
・Only fill fuel tank with gasoline.
・Keep sparks, open flames or other form of ignition (such as match, cigarette, static electric
source) away when refueling.
・Never overfill the fuel tank. Leave room for fuel to expand. Overfilling the fuel tank can result in a
sudden overflow of gasoline and result in spilled gasoline coming in contact with HOT surfaces.
Spilled fuel can ignite. If fuel is spilled on the inverter, wipe up any spills immediately. Dispose of
rag properly. Allow area of spilled fuel to dry before operating the inverter.
・Wear eye protection while refueling.
・Never use gasoline as a cleaning agent.
・Store any containers containing gasoline in a well-ventilated area, away from any combustibles
or source of ignition.
・Check for fuel leaks after refueling. Never operate the engine if a fuel leak is discovered.
Never operate the inverter if powered items overheat,
electrical output drops, there is sparking, flames or smoke
coming from the inverter, or if the receptacles are damaged.
Never use the inverter to power medical support equipment.
Always remove any tools or other service equipment used
during maintenance from the inverter before operating.
Never modify the inverter.
Never operate the inverter if it
vibrates at high levels, if engine
speed changes greatly or if the
engine misfires often.
Always disconnect tools or
appliances from the inverter
before starting.

USB Duplex: 5V DC that come in 1 amps and
2.1 amps.
AC Reset: If the inverter is overloaded, the
reset breaker will trip. The engine will continue
to run, but there will be no output from the
inverter. Unplug the devices and reduce the
load. Push in the reset breaker to reset it.
One Push Start: Press this button, the engine
can start and stop Press this button for 3-5
seconds until the green light is on, and then
press the ON/OFF button on the remote
control key until the light is off. At this time,
the remote control matches successfully.
Ground Terminal: The ground terminal is
used to externally ground the inverter.
Multifunctional LED Digital Display Meter:
Red light ( LOW OIL ) means that the amount
of oil is too low, red light (OVERLOAD) means
that the machine overload, green light (POWER)
means normal operation. LED Digital Display
shows time, voltage, power, frequency and fuel
level; Time: scrolling display of single running
time and accumulated running time.
Efficiency Mode Switch: When turned to the
ON position, the engine will sense the load
needed and run at a slower RPM to save fuel.
Parallel Connectors: To increase AC power
output, the connector sockets are used to
connect the two same type generator with
special paralleling cords.The connector
sockets is only used to the communication
between the inverters. they can not used for
AC power output. The special paralleling
cords shall be purchase separately, and they
shall be approved by certification body.
AC Protector: If the inverter is overload, the
AC protector will trip to block current.
CO Alarm: Flashing red light: dangerous
levels of carbon monoxide gas have built up
leave immediately until area has aired out.
Move generator to well-ventilated area
before operation. Flashing yellow light: carbon
monoxide sensor malfunction, sensor
needs service.

BEFORE STARTING THE INVERTER
OPERATION
BEFORE STARTING THE INVERTER,
REVIEW SAFETY SECTION STARTING
ON PAGE 5.
Location Selection - Before starting the inverter,
avoid exhaust and location hazards by verifying:
・You have selected a location to operate the
inverter that is outdoors and well ventilated.
・You have selected a location with a level and
solid surface on which to place the inverter.
・You have selected a location that is at least 6
feet (1.8 m) away from any building, other
equipment or combustible material.
・If the inverter is located close to a building,
make sure it is not located near any windows,
doors and/ or vents.
DANGER
Weather - Never operate your inverter outdoors
during rain, snow or any combination of weather
conditions that could lead to moisture collecting
on, in or around the generator.
Dry Surface - Always operate the inverter on a dry
surface free of any moisture.
No Connected Loads - Make sure the inverter has
no connected loads before starting it. To ensure
there are no connected loads, unplug any electrical
extension cords that are plugged into the control
panel receptacles.
Starting the inverter with loads already applied
to it could result in damage to any appliance
being powered off the inverter during the brief
start-up period.
Grounding the Inverters
There is a permanent conductor between the
portable generator stator winding and the frame.
Consult with your local municipalities for your
grounding codes.
Carbon Monoxide Specification
CO DETECT technology monitors the accumulation
of carbon monoxide (CO), a poisonous gas
produced by engine exhaust when the generator
is running. If CO Sensor detects unsafe elevated
levels of CO gas, it automatically shuts off the
engine CO Sensor is not a substitute for an indoor
carbon monoxide alarm or for safe operation.
DO NOT allow engine exhaust fumes to enter a
confined area through windows, doors, vents or
other openings. Generators must ALWAYS be used
outdoors, far away from occupied buildings with
engine exhaust pointed away from people and
buildings. Meets the requirements of
ANSI / PGMA G300-2018.
WARNING
Be sure the inverter is properly
connected to earth ground before
operating.
WARNING
NOTICE
NOTICE
Using a generator indoors
CAN KILL YOU IN MINUTES.
Generator exhaust contains carbon monoxide.
This is a poison you cannot see or smell.
NEVER use inside
a home or garage,
EVEN IF doors and
windows are open.
Only use OUTSIDE
and far away from
windows, doors,
and vents.
Avoid other generator hazards.
READ MANUAL BEFORE USE.
Always operate the inverter on a
level surface. Placing the inverter
on non level surfaces can cause
the inverter to tip over, causing fuel
and oil to spill. Spilled fuel can
ignite if it comes in contact with an
ignition source such as a very hot
surface.
Only operate the inverter on a solid, level surface.
Operating the inverter on a surface with loose
material such as sand or grass clippings can
cause debris to be ingested by the inverter that
could:
• Block cooling vents
• Block air intake system
