FCC Statement
The equipment complies with part 15 of the
FCC rules. The operation shall meet the fol-
lowing two conditions:
1. The device may not cause harmful inter-
ference, and
2. The equipment must accept any interfer-
ence received, including interference that
may lead to accidental operation.
3. The equipment complies with FCC radia-
tion exposure limits for uncontrolled envi-
ronments. The equipment shall be
installed and operated at a minimum dis-
tance of 20 cm between the radiator and
the vehicle body.
NOTE: According to part 15 of the FCC rules,
the equipment has been tested and found to
comply with the limitations of class B digital
equipment. These restrictions are intended to
provide reasonable protection against harm-
ful interference with residential facilities. The
equipment can be used and radiate RF
energy. If it is not installed and used according
to the instructions, it may cause harmful inter-
ference to radio communication. However,
there is no guarantee that interference will not
occur in a specific installation. If the equip-
ment does cause harmful interference to radio
or television reception, it can be determined
by turning off the equipment, and users are
encouraged to correct the interference by one
or more of the following measures:
1. Reposition or reposition the receiving
antenna.
2. Increase the distance between the device
and the receiver.
3. Connect the device to an outlet on a circuit
different from the circuit to which the
receiver is connected.
4. Consult your dealer or experienced radio /
TV technician for assistance.
Electrocution. Grasp electrical cord plug when
unplugging the electrical cord from the outlet. Do
not touch metal prongs. Failure to do so could
result in death or serious injury.
WARNING
(000714a)
(000162)
Explosion. Do not dispose of batteries in a fire.
Batteries are explosive. Electrolyte solution can cause
burns and blindness. If electrolyte contacts skin or eyes,
flush with water and seek immediate medical attention.

Know Power Station Limits
Overloading a Power Station can result in
damage to the Power Station and connected
electrical devices. Observe the following to
prevent overload:
• Add the total wattage of all electrical
devices to be connected at one time. This
total should NOT be greater than the Power
Station's wattage capacity.
• The rated wattage of lights can be taken
from light bulbs. The rated wattage of tools,
appliances, and motors can be found on a
data label or decal affixed to the device.
• If the appliance, tool, or motor does not
give wattage, multiply volts times ampere
rating to determine watts (volts x amps =
watts).
• Some electric motors, such as induction
types, require approximately three times
more watts of power for starting than for
running. This surge of power lasts only a
few seconds when starting such motors.
Make sure to allow for high starting wattage
when selecting electrical devices to con-
nect to the Power Station:
1. Calculate the watts needed to start the
largest motor.
2. Add the starting watts to the running watts
of all other connected loads.
The Wattage Reference Guide is provided to
assist in determining how many items the
Power Station can operate at one time.
NOTE: All figures are approximate. See data
label on appliance for wattage requirements.

Troubleshooting if the flashing persists.
Using the Power Station
(Discharging)
Starting the Power Station
NOTE: If using only one, or all three AC
receptacle(s), the load must not exceed 13.3A
current, 1600 watts of power.
1. Confirm the device or equipment requiring
power is OFF.
2. Press and hold ON/OFF button for three
(3) seconds to turn unit ON.
3. Connect equipment.
– AC Power - Turn ON AC power switch.
– DC Power (USB/vehicle charging) -
Turn ON DC power switch.
NOTE: Power Station will automatically turn
off after 60 minutes if not in use.
Charging the Power Station
IMPORTANT NOTE: Always use the
charging cord(s) supplied with the unit.
NOTE: The ambient temperature for product
use should be between 0 °C to 40 °C (32 °F to
104 °F).
Place the Power Station on a clean, dry, level
surface.
The Power Station can be charged three (3)
separate ways.
1. See Figure 3-1. AC Power Supply - Insert
AC charging cord from the AC charging
port to the wall electrical outlet.
Figure 3-1. AC Wall Charging
2. See Figure 3-2. Solar Panels - Insert DC
charging cord from the solar panel into the
DC charger port.
NOTE: Charging time is dependent on the
solar panel power and light intensity.
(000752)
WARNING
Injury and equipment damage. The use of non-Generac
equipment could result in unit damage, death or serious
injury.

8 Owner’s Manual for Power Station
NOTE: Confirm the solar panel is compatible
with the power station before connecting the
solar panel. Power stations support 10-
28VDC, 30A max, up to 468W of solar input.
Solar panels not meeting these requirements
may damage the power station.
Figure 3-2. Solar Charging
3. See Figure 3-3. Car Charging - Insert DC
charging cord from the car power supply
into the DC charger port.
NOTE: Car charging the power station will
drain the vehicles battery. It is recommended
to only charge the power station while the
vehicle is running to prevent depletion of the
vehicle’s battery.
NOTE: Always disconnect the power station
when the vehicle is turned off.
Figure 3-3. Car Charging
Simultaneous Charge Inputs
Power Stations are compatible with simultane-
ous AC and DC charge inputs (example: solar
+ generator).
The charging input reference guide provides
suggested charge input power range.
NOTE: Exceeding suggested charge input
power can reduce battery life.
Pass-Through Charging
Power Stations support simultaneous
charging and discharging of the battery during
operation.
NOTE: This device is not designed to be used
as a UPS (Uninterrupted Power Supply).
NOTE: Pass-through charging can reduce
battery life.
Parallel Connection
• The rated power of equipment should not
exceed the total rated power of parallel
products.
• Only use with compatible Power Stations
and Generac Portable Inverter Generators.
See parallel kit manual for complete list of
compatible devices.
• The use of non-Generac equipment could
cause unit damage or personal injury.
• Connect parallel devices before turning the
power ON.
• Turn the power OFF before disconnecting
parallel devices.
Paralleling two Power Stations provides
almost twice the power.
1. See Figure 3-4. Insert the parallel plugs
from the parallel box into the Power Sta-
tions.
2. Press ON/OFF button on the Power Sta-
tions.
3. Press AC button on the Power Stations.
4. Plug electrical equipment into the AC out-
lets. Turn ON equipment.
NOTE: If a fault occurs, the AC power will turn
off and the fault light will flash for 10 seconds.
NOTE: AC and DC Power Station outlets can
be used at the same time as the parallel kit
although output is limited to the Power Sta-
tion’s rating.

77°F (15°C - 25°C) and a max temperature
of -4°F - 113°F (-20°C - 45°C).
• The Power Station should be between 30-
60% state of charge for long term storage.
Recharge every three (3) months to main-
tain battery life.
Disposal
Contact an IASD to return Power Station for
disposal.
FAQ
Q: Why does the power station show power
output when I don’t have anything plugged
in?
A: The power station uses power for the dis-
play, fans, inverter, etc. Power usage is
shown on the LCD display for user aware-
ness.
Q: Can the GB1000/GB2000 be discharged at
the same time it is charging?
A: Yes, both models can be simultaneously
charged and discharged.
NOTE: Pass-through charging can reduce
battery life.
Q: How do I estimate the operating time for a
device?
A: Estimated operating time (hrs) = Capacity
(Wh) * 0.8 / Device Load (W).
Q: Can I use the GB1000/GB2000 outside?
A: Yes, both models are rated for temporary
outdoor use.
NOTE: The power stations should NOT be
exposed to rain or moisture.
Q: How do I silence the beeping sound when
pressing buttons?
A: Hold the DISPLAY button for five (5) sec-
onds.
