Power-on/off
The main power switch controls the product to power on or power off.
1Press the main power switch to power on the product.
2In power-on state, long-press the main power switch for 2 seconds to power off the product.
3In power-on state you can press the main power switch to make the display switch between
on and off states.
After the product is powered on, the
display is turned on, and the indicators on
the top of the product are also turned on.
If no operation is performed within 3
minutes, the display will be turned off
automatically. In this case, you can press
the main power switch to turn on the
display. In power-on state you can press
the main power switch to make the display
switch between on and off states. After you
press the main power switch to power off
the product, the USB power supply, DC
power supply, and AC power supply are all
turned off. When all output switch are off
and nothing is operated, it will turn off
automatically after 2 hours.
DC output
1Turn on the main power supply.
2Press the DC output switch button. After
that, DC output ports (including the car
charger port, DC5521 port, and Anderson
port) start to output power supply, and
the DC switch indicator is turned on at the
same time.
3Press the DC output switch again. After
that, the DC output is turned off, and the
DC switch indicators are turned off. When
the output of each 12 V DC port is less
than 3 W for 12 hours continuously, the

DC output switch will turn off
automatically.
USB output
1Turn on the main power supply.
2Press the USB output switch. After that,
the USB power supply is started, the
USB-A and Type-c ports start to output
power supply, and the USB switch
indicator is turned on at the same time.
3Press the USB output switch again. After
that, the USB power supply is turned off,
and the USB switch indicator is turned off.
AC output
1Turn on the main power supply.
2Press the AC output switch. After that,
the 120 V AC output is turned on, the AC
socket starts to output power supply,
and the AC switch indicator is turned on.
3Press the AC output switch again. After
that, the 120 V AC output is turned off,
and the AC output switch indicator is
turned off. When the output of AC port
is less than 15 W for 12 hours
continuously, the AC output switch will
turn off automatically.
You can press the AC output switch during AC charging to turn on the AC output to enter the EPS
mode, and then the AC socket can take power supply directly from the AC input port. In this case,
the power of charging and 120 V AC output cannot exceed the limit power of AC input (peak
value < 1400 W); otherwise, the AC input may be disconnected for protection. In EPS mode,
when the AC output power exceeds 1000 W, the AC input cannot power the battery, and
meanwhile the maximum AC output power is 1100 W. In EPS mode, once the power supply fails
due to abnormal AC input, the product immediately switches to battery power supply within 30
ms.
During DC charging, the 120 V AC can still output power supply normally, that is, charging and
discharging can be performed simultaneously.

After the AC input charging port is connected to the mains:
1In power-off state, the product wakes up automatically and charges the battery in
accordance with the preset charging power.
2When the 120 V AC output is operating properly, it will switch to EPS mode for power supply
and start charging the battery at approximately 300 W.
You can press the fast
charging switch to cycle
between low-rate charging
and fast charging of AC
input. After the power
supply is turned on,
low-rate charging is
performed by default.
Note: When the AC input is connected to the mains, if you do not need to use the AC output,
please turn off the AC output switch, otherwise it will reduce the AC charging power.
For the AC charging indicators, refer to the following table.

After the DC input charging port is connected to a car charger or a solar panel:
1In power-off state, the product automatically wakes up and starts charging.
2In power-on state, the product supports charging and discharging simultaneously.
Note:
In smart car charging mode, if
the car engine is not working,
car charging is not performed
so as to protect the 12 V
battery. Car charging can be
performed normally only after
the car engine starts working.

This product supports the same
type of solar panels. The
company shall not bear the
responsibility for any damage
caused by improper operations
or using different types of solar
panels.
In EPS mode, 120 V AC output is used, which preferentially gets power supply from AC input, and
the battery is in standby mode.
After the 120 V AC output is started, the AC input is connected to the mains, the AC socket
switches to the mains, and the battery is in standby mode.
When the AC input is connected to the mains, if you press the AC switch to start the 120 V AC
output, the AC socket will directly take power supply from the mains.
When the AC input is abnormal and fails to supply power, the product immediately switches to
battery power supply within 30 ms to maintain normal 120 V AC output.
Note:
The power supply in EPS mode involves switching time and cannot replace professional UPS
products. When using EPS mode, you need to confirm whether the power demands of electrical
appliances are satisfied.
To use the EPS
function, ensure
that the load does
not exceed the rated
power. The EPS
function may fail to
start when the rated
power is exceeded.
When the battery level is above 20%, the indicator is green. When the battery level is below 20%,
the indicator is red.

Long-term backup power mode: The product can be connected to the mains for a long period of
time. The built-in intelligent system of the product automatically manages charging and
discharging. If the product is not used for a long period of time, to meet the power backup
requirement, the AC input port can always be connected to the mains, and it is intelligently
determined that the battery is automatically recharged every 45 days. This mode is enabled by
default.
Enhanced overload mode: For the load requirements, when a load exceeds the rated AC output
power of the product, UPS protection is performed to output power supply for the load. In this
case, the output power is limited to the maximum output power. The actual loads that can be
supported depend on the load types. This mode is enabled by default.
The power grid system is automatically identified in accordance with the frequency of mains
charging. When the AC output is turned on the next time, the product automatically switches to
the frequency mode corresponding to the mains. This mode is enabled by default.
