7. USING THE POWER INVERTER
1. Check the output voltage and capacity of the battery. The battery (s) should match the
voltage of the inverter and have enough capacity for the load. See Section E for more
information.
2. Connect your inverter to your battery bank and do not to reverse the polarities of the
connection. See Section F.
3. Press the power switch button on your inverter for 0.5 seconds and a green LED will
light up indicating that the inverter is on.
4. Before plugging anything into your inverter, make sure the appliance you are trying to
power is shut OFF, then plug it into the AC outlet of your inverter and power on your
appliance.
5. Once finished using the inverter, turn off your electrical appliance and the inverter.
The indicator lights should be off.
6. The cooling fans inside the inverter do not work until the case temperature reaches
approximately 104°F.
7. If you do not plan to use the inverter for a long period of time, disconnect it from your
battery bank. Leaving the inverter on and connected for long periods of time may
harm the equipment and over discharge the battery.
8. The USB port on this unit can provide a stable line of 5V DC current. It will auto detect
your device's max charging current from 0 to 2.4A current. Be sure to double check
your device to make sure it doesn't exceed these requirements.
8. SOFT START TECHNOLOGY
The soft start technology built into this inverter protects the unit from delivering too
much AC power at once by gradually increasing the AC voltage pushed out. To make
sure that you are utilizing this feature, turn on the appliance being used before turning
on the inverter. This is especially necessary for equipment that has an inductive load or
electrical motor.
9. OUTPUT VOLTAGE & WAVEFORM
The electrical waveform output of this inverter is a pure sine wave, which has the
same quality as utility and/or domestic power. This type of waveform is suitable for most
electrical devices, appliances and tools. This pure sine wave unit provides more
capabilities than modified sine wave inverters because it is a cleaner form of power.
The pure sine wave also effectively reduces the noise produced while using
appliances.
10. LED DISPLAY
While the inverter is working, the input voltage and output power will be shown on the
LED display screen by turns. When the inverter goes into protection, the following code
may be shown:
1. LO means the inverter is in under voltage protection.
2. HI means the inverter is in over voltage protection.
3. OL means the inverter is in overload protection or short-circuits protection.
4. OH means the inverter is in OVER HEAT protection.
11. PROTECTION FEATURES
1. Input under-voltage alarm: When the input DC voltage is lower than 10.1V (20.2V),
the buzzer will whistle intermittently to remind that the inverter will go into the under
voltage protection. Pay attention to save the data if you are using computer.
2. Under voltage protection: The inverter will automatically shut down when the input DC
voltage is lower than 9.8V(19.6V).The buzzer will whistle continuously and the green
light is off, red light is on. Please turn off the inverter and use it after recharging the
battery.
3. Over voltage protection: The inverter will automatically shut down when the input DC
voltage is higher than 16V(32V).The buzzer will whistle continuously and the green
light is off, red light is on. Please turn off the inverter and adjust the input voltage to
the admissible range.
4. Overload protection: The inverter will automatically shut down when the load is higher
than the rated power. The buzzer will whistle continuously. Turn off the inverter and
resume to normal operation after taking away the excessive load.
5. Short-circuit protection: The AC output will be automatically shut down when short
circuited. It will automatically reset after the problem is solved.
6. Thermal protection: The unit will get bot during operation. If the temperature is higher
than 149°F, the inverter will automatically shut down. Then the buzzer will whistle
continuously and the green light is off, red light is on. Please turn off the inverter, and
continue using it after the temperature goes back to normal naturally. Meanwhile find
out the factors causing the fault, such as ventilation, ambient temperature, vent, load
power and so on. It can avoid similar things from happening again.
**NOTE** The numbers in the parenthesis are for 24V models. In the case of over
voltage, under voltage and thermal protection, the inverter will shut down. When the
inverter is in the OFF position, the inverter doesn't consume battery current.
12. HOW TO CHANGE FUSE
1. Firstly disconnect the inverter and external batteries, solar panels, load etc all the
connections.
2. Unscrew the side plate screws and pull out the bottom plate.
3. Use pliers to clamp car fuse inside the product, and pull out .
4.Replace the same specifications of the car fuse, and then install the bottom and side
panels, and screw well.
