9. OUTPUT VOLTAGE WAVEFORM
When the product is working, the LCD on the inverter displays the current battery
power, input voltage and output power. When the inverter is in the protection state,
the LCD will display a warning symbol and the current protection state, as shown
below:
The output voltage waveform of the inverter is "pure sine wave", which is a waveform
with the same characteristics as household AC power, and even higher purity than
household AC power. This type of waveform is suitable for most loads, Including linear
or switching power supplies, transformers, electric motors and so on in electronic
equipment. Compared with the modified sine wave type, for electric fans, refrigerators
and other inductive load, it can improve the power factor, improve the utilization rate of
power, can effectively reduce the noise of electrical work; For capacitive loads such as
notebook adapters, it can reduce the impact current during work, reduce interference,
improve stability, and more effectively extend the service life of electrical appliances.
10. WORK INSTRUCTIONS
1. When the warning icon and "IN: LOW" are displayed, it indicates that the inverter is
currently under voltage protection.
2. When the warning icon and "IN: HIGH" are displayed, it indicates that the inverter is
currently in the over voltage protection state.
3. When the warning icon and "OVERLOAD" are displayed, it indicates that the inverter
is currently enterin
g the output overload or short circuit protection state.
4. When the warning icon and thermometer icon are displayed, it indicates that the
inverter is currently in the overheating protection state.
6) When not in use, press the power switch on the inverter, the power indicator on the
inverter and the remote control box are off, indicating that it has been shut down.
② How to use USB port power supply
The product provides two USB interfaces, which can provide a stable 5V DC voltage,
and the maximum output current of each USB interface is 2.4A, which can power or
charge portable devices with USB interfaces
Note: Before using USB interface for power supply, please make sure that the
device can be powered through USB interface and the maximum working
current does not exceed 2.4A.
8. ABOUT SOFT START TECHNOLOGY
This product has soft-start technology, that is, after turning on the inverter switch, the
output voltage gradually rises from low to normal. This feature can reduce the impact of
large current at the moment when the appliance is turned on, and help to turn on those
hard-to-start loads and High-power electrical appliances.
Temperature protection:
The product will heat up during use. If the temperature
exceeds 65°C, the inverter will automatically shut down and the buzzer will beep for a
long time. The user should turn off the power switch of the inverter and continue to use it
when the inverter is naturally cooled to normal temperature. At the same time, the user
should check the reasons for the temperature protection, such as whether the
ventilation conditions are good, whether the ambient temperature is too high, whether
the vent is blocked, whether the load power is too large, etc., solve the above problems
to avoid recurring temperature protection.
5. Short-circuit protection: When the output is short-circuited, the inverter will
automatically turn off the AC output.
4. Overload protection: When the load power is higher than the rated power of the
product, the inverter will automatically shut down and the buzzer will beep for a long
time. The user should turn off the inverter power switch and reduce the load power to
the allowable range before using it.
3. Input over voltage protection: When the input DC voltage is higher than 16V/32V, the
inverter will automatically shut down and the buzzer will beep for a long time. The
user should turn off the inverter power switch, adjust the input voltage to the
allowable range before using.
2. Input undervoltage protection: When the input DC voltage is lower than 9.5V/19V, the
inverter will automatically shut down and the buzzer will beep for a long time. The
user should turn off the inverter power switch and recharge the battery in time before
usin
g it.
1. Input undervoltage reminder: When the input DC voltage is lower than 9.8V/19.6V,
the buzzer will give an intermittent alarm to remind the user that the inverter will soon
enter the undervoltage protection state. If you are operating a computer or other
equipment, you should save it in time data.
11. PROTECTION FUNCTION
A. CORRECTLY CONNECTING THE INVERTER FOR FIRST USE.
1) Secure the provided Negative (black) DC cable connect to the Negative (-) bolt on
the inverter, and the other end to the Negative (-) post on the battery.
3) The nuts of the connection posts must be tightened to ensure well connected.
4) Press the power switch for one second, because it is a long press type switch.
2) Secure the provided Positive (Red) DC cable to the Positive (+) bolt on the
inverter, and the other end to the Positive (+) post on the battery.
! Ensure Your Battery Size Is Big Enough And Voltage Is Correct.
