Input Power Knob
When the product is connected to the AC mains for charging, the power is adjusted
according to the actual input voltage. The clockwise rotation increases the input power,
and the counterclockwise rotation decreases the input power. It is worth nothing that
charging this product at low power is beneficial for extending battery life.
Cooling Suction/Exhaust Port
When the product reaches the temperature threshold set by the system, the cooling fan
will automatically run, accompanied by a certain fan noise (fan noise below 60dB is
normal). Do not block the cooling suction/exhaust port during use of this product, and do
not place any object within the range of 30CM.
AC Button (AC output port, the sum of electrical load power should be
<2400W)
Tap the AC button to enable the AC output function. Since there may be differences in the
AC output frequency in different regions, if you need to switch the frequency, the
operations are as follows: Press and hold the AC button for 2 seconds to enter the
frequency switching mode, the 50Hz or 60Hz icon will flash on the display, short press the
AC button again to select 50Hz or 60 Hz icon will flash on the display, short press the AC
button again to select 50Hz or 60Hz; when the icon stops flashing and displays 50Hz or
60Hz, it indicates the switch is successful.

UPS Mode
UPS Feature
This product has the function of backup uninterruptible power supply. The usage and
operation precautions are as follows:
As shown in Pic 1 below, when the product is connected between the wall socket and the
electrical appliance, and the power supply and AC switch of the product are in the ON
state, the product enters the UPS working mode. The AC mains in the socket supplies
power to the electrical appliance through the bypass circuit, and also charges the product.
In this working state, the rated power off the electrical appliance must be lower than
1100W, otherwise overload protection may be triggered.

12
As shown in Pic 2 below, when the AC mains at the socket end is disconnected, the bypass
output inside the product stops working, the product switches to a bidirectional inverter
circuit within 10ms, and the circuit outputs supply power to the electrical appliance to
ensure that the electrical appliance is uninterrupted and works normally during the
process.
Connection of Solar Panels
Under the condition of light, this product can be connected to the solar panel and getting
charged. The charging power is determined according to the conditions of light and
weather.
In this charging mode, we support solar panel input within 500W, and the input voltage
cannot exceed 50V, otherwise the product abnormality caused by it will not be covered by
the warranty.
We recommend the following two charging schemes:

Car Charging
When the car is in the process of starting, connect the car charging port on the car and the
product through the car charging cable to charge the product. The connection method is
shown in the picture below:
This product supports 12V/24V car charger charging, please pay attention to the following
two points when using this method to charge:
Please use it when the car started, otherwise the car battery may be exhausted.
Vehicle charging power is usually in the range of 90W-120W, and the charging time
is long. If fast charging is required, the AC mains charging is recommended.
