Introduction
Your 250-watt power inverter converts 12-volt vehicle battery power into 230 volts of AC power. You can use the inverter in your vehicle to operate many types of appliances that use AC power such as TVs, VCRs, portable computers, power tools and lights for emergency or camping use. The inverter works with your vehicle’s engine turned on or off (accessory mode). It provides a continuous output of up to 250 watts.
Basic operation
-
Use the right operating voltage for both the input and output of the inverter. Powering devices with power rating:
-
Less than 150 Watts by connecting the cigarette lighter plug into the vehicle’s cigarette lighter socket.
-
More than 150 Watts by connecting RED terminal from the inverter to + of battery terminal and connect BLACK terminal from inverter to of the battery terminal.
-
Insert the plug of your appliances into the AC socket at the front of the inverter.
-
Turn ON the power switch that is located at the front of the inverter, and the green LED will light as an indicator that the unit at work.
Caution!
- Do not power more than 150 watts when the power inverter is connected to the car cigarette lighter socket power supply. Doing so may damage your car’s fuse.
Recommendations
- If the power inverter makes a beeping sound, turn OFF the power inverter and disconnect all appliances from the inverter and disconnect the inverter from the power supply. The beeping sound is simply the low battery warning, which indicates that the voltage of the battery power supply is getting low. Please restart the vehicle engine before operating the power inverter.
- When you are not using the inverter, turn the switch to OFF and disconnect the inverter from the power supply.
- Disconnect the inverter when starting the vehicle’s engine.
Battery use
To avoid over-discharging your vehicle’s battery, you should run your engine for 10-20 minutes to recharge the vehicle’s battery after 2-3 hours of operating the inverter. If you choose to connect the vehicle directly to your battery terminals, it is important to connect with the right polarity (Connect
-
from the inverter to + of battery terminal and connect from inverter to of battery terminal).
Caution! The following operation will damage the unit:- Reverse polarity by connecting the wires to the incorrect terminals.
- Connecting the battery charger to replenish the battery without disconnecting the inverter first.
Measuring the ac voltage
The output waveform of the AC output is a MODIFIED SINE WAVE. To measure the AC output voltage, you must have a TRUE RMS VOLTMETER.
Safety precautions
Do not open the case of the inverter. The high voltage inside the unit is the same type of power as our electrical outlets at home. Do not let the cord of the inverter or any appliance’s cord get wet. Do not operate the inverter in or around water. The voltage of the unit makes an electrical shock hazards if operated in wet conditions. Do not connect the AC inverter directly to another AC power source. Allow at least 1 inch of clearance around the inverter for airflow. If you operate the inverter in a moving vehicle, you need to secure the inverter to prevent it from shifting around while the vehicle is moving. If there is anything wrong with the inverter, disconnect from the 12V power supply.
Troubleshooting
**TROUBLE/INDICATION** |
**POSSIBLE CAUSE** |
**SUGGESTED REMEDY** |
|---|---|---|
| No AC output-the Green LED light is not on | •DC input below 10 Volts |
•Recharge or replace the battery
No AC output –inverter is cold| Poor connection with the battery.| •Disconnect
load from the inverter. Reconnect the unit to the battery terminals.
Shut down after operating for a long time| •Over-temperature| ‘Disconnect the
inverter and put it aside for a while to cool down the unit.
Shut down after operating a short time and the inverter is cold| Over-Load|
Reduce the wattage of the inverter’s load
Maintenance
Very little maintenance is required to keep the inverter operating properly.
Description
500W Peak power- Allow you to power appliances that require a large amount of
initial power to work (such as many TVs and power tools).
Low Battery alarm- the inverter sounds an audible alarm and then turns itself
off if the source battery becomes too low. Auto shutdown/reset protection— the
inverter temporarily shuts itself down to protect itself from overheating.
Overload/Short Circuit Protection— the inverter automatically turns itself off
if the connected load is too high or if it shorts. AC Outlet–allows you to
power AC appliances.
Heat Dispersal Caution
The inverter generates heat while it is working. This is not a malfunction.
However, if the inverter gets too hot while working, it will turn off by
itself. Position the inverter where air flows freely around it to allow the
heat to disperse. The inverter’s thermal protection prevents it from operating
when its temperature exceeds 140+/-9 °F (60+/-5 °C).
Important: Additional Safety Information
This Power Inverter is NOT intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience or knowledge. Unless they are supervised or have been given instruction concerning the use of the Power Inverter by a person responsible for their safety.
