panel to the product even it is off status.
● Max. current of the solar is 12A.
(3) Charging mode 3: From the car lighter port
●Press the power button and connect it to the cigarette lighter port through the car charging
cable.
●Enter the setting interface as shown in (Figure2) through the display screen to set DC
input source to car mode; The product can be charged with 8.2A maximum current.
- 07 -

(4) Charging Mode 4: From a generator (gasoline, propane or diesel)
●Connect the AC adapter input to the generator and the output port to the AC charging port
of the machine.
●Press the power button, the product will be charged, the charging will automatically stop
when it reaches 100%.
(5) Charging mode 5: from lead acid battery

7. Discharging
(1) Turn on 12V / 25A, 12V / 3A, cigarette lighter port, USB and type C output: first, press
the power button, then enter the main interface through the touch screen, click the DC ON/
OFF button and confirm, Turn off these output, and also click the DC on / off button and
confirm.
(2) Turn on AC output: first, press the power button, then enter the main interface through
the touch screen, click the AC ON/ OFF button and confirm. Turn off these AC output ports,
and also click the AC ON/ OFF button and confirm.
9. Examples of loads
(1) 12V / 25A, 12V / 3A, cigarette lighter port, USB and type C output port are suitable for
most products in the market, but some products may trigger overcurrent protection if there is
a large current impact at the moment of starting.
(2) The power of electrical products used for AC output should be less than 2000W.
According to the different electrical products, when the rated power is less than 2000W,
some air conditioners, motors and other devices that need instantaneous high current when
starting may trigger overcurrent when the ratio of peak value of rated current exceeds 3:1.
At this time, we recommended that you select the electrical appliances with lower power
rate.
(3) When the output is overload, over-current or short circuit, the product will turn off the
corresponding output, and then it will automatically start twice (at an interval of 20s). If there
is still an overload, over-current or short circuit alarm, the output will be locked, and it needs
to be manually troubleshooting and then restart. If the output stops repeatedly after restart,
please stop using it immediately (only after troubleshooting) or contact the seller or
maintenance agent for help.
8. Application scenario
(1) Outdoor: Car equipment: car fridge, car vacuum cleaner and other car equipment;
Camping equipment: garden electric tools (power tools such as blowers, lawn mowers,
electric drills, electric saws), BBQ grills, LED lights, etc.
(2) Indoor: Refrigerator, kitchen devices such as kettle, toaster, blender, coffee maker, rice
cooker, laptops, phones, lighting, etc.

10. Estimation of operating time
2000Wh × DOD × η ÷ (load W) = charging time（unit：h）
Note：DOD is the battery discharge depth，η is the local inverter efficiency,
DOD=90%,η=88%。
(4) When the battery power is discharged to 0%, the DC and AC output will automatically
turn off. Only when the battery power is charged to more than 5%, the DC and AC output
can be turned on, which is to protect the battery and enhance its cycle life.
(5) This machine supports charging and discharging simultaneously.
