ELinz INTPWRM3000 Pure Sine Wave Inverter
Introduction
The inverter is electronic equipment that can convert DC power (from the battery, solar cells, wind turbines, etc.) to AC power. The inverter uses high-frequency power conversion technology, as well as a ferrite transformer instead of the old bulky silicon steel transformer. This is why a power inverter is lighter and smaller than other similar inverters. When the unit is in use, its output waveform is a sine wave.
To ensure maximum reliability and efficiency, this inverter must be installed and used properly. Prior to installation, please read the user’s manual. Improper usage may possibly lead to inverter damage, accidents, or injuries Please read this manual, especially the “Precautions and Safety Notice” section to ensure your safety. After reading the instruction manual, please keep it with the warranty card for future reference.

Proper Environment for the Inverter
To get the best results, please place the inverter on a flat surface, such as
the ground, the floor of the car, or another solid surface. The location where
you are planning to install and place the inverter should meet the following
criteria:
- Dry. Place the inverter in a dry place. Do not let it get into contact with water, liquids, or moisture.
- Cool. Keep the temperature between 0 to 40 degrees Celsius. Do not place the inverter next to heat vents and other test devices. Also, avoid placing the inverter under direct sunlight.
- Well-ventilated. Please make sure that the inverter is placed in a well-ventilated area, especially when in use. Do not place anything on or around the inverter, particularly near the exhaust fan.
- Safe. Do not use the inverter in an area where combustible materials and flammable gases are present.
- Fully charged battery. Please make sure that the battery you will use with the inverter is fully charged. Use good lead-acid batteries for the best results.
Installation and Proper Usage
- The inverter can be used with one or more batteries. Using 150AH or a larger battery is highly recommended.
- Before connecting the inverter and battery, make sure that there is no flammable gas present. Use the cables that come with the unit to connect the inverter and battery.
- Make sure to connect the red cable to the red post of the inverter and the positive terminal of the battery.
- Then, please connect the black cable to the black post of the inverter and the negative terminal of the battery. Please ensure that all connections are solid and reliable. Improper cable connections may result in overheating, as well as post head and lug damage. It can also reduce battery time.
- When the inverter is switched on and your battery is fully charged, the power LED glows green. If the power LED grows red, there might be a problem. It can be the battery voltage is too high or too low, or the inverter output is overloaded. Find a way to solve the problem before using the unit.
- 12v inverter power source can be a 12v battery or a few 12v parallel batteries to increase power supply time.
Note: Before plugging in any appliance/equipment, make sure both the inverter and the appliance are turned off. When you turned the inverter on and the LED glows green, then you can switch on connected devices and appliances one by one. If the LED light is red, it means the inverter is overloaded. Restart the inverter or disconnect certain appliances to reduce the load.

Operating Tips
Rated current and the actually used equipment
If the nominal current or power of electromotive tools, household appliances,
and audio-visual equipment has a higher or lower range than normal, the
inverter’s overload protection will be triggered upon start-up. The inverter
is also most likely to drive resistive loads and switch power supply loads. A
resistive load is usually linear and can work with a full load. Examples of
appliances with resistive load are electric stoves, rice cookers, and LCD TVs.
Some audio-visual equipment and electromotive tools need more power than the
resistive load to work normally. Examples of these tools are asynchronous
motors, CRT TV, compressors, and pumps. They require two to six times the
amount of operating power to start. Test the equipment first before using it
with the inverter.
Troubleshooting Tips
- Problem: The inverter shut down and the indicator light is off.
- Possible cause 1: The battery is weak
- Solution: Examine the battery and replace if necessary.
- Possible cause 2: Batteries connected in reverse polarity.
- Solution: Check the battery’s connection, if any damage is done to the inverter, it should be replaced
- Possible cause 3: Poor contact at terminals
- Solution: Unhook and re-hook the 12V connections and try again.
- Problem: The inverter shut down and the RED indicator is on
- Possible cause 1: The rated power of the AC product is higher than the nominal power of the inverter causing the overload shutdown.
- Solution: Try to use AC electric products whose power level is less than the converters’ nominal power.
- Possible cause 2: The power of the AC electric product is more than the nominal power of the inverter, and the rated power is quite high leading to overload shutdown.
- Solution: The peak power of the AC electric product could be higher than that of the inverter, try to use electric products with the same peak power as the inverter.
- Possible cause 3: The battery runs out
- Solution: Charge or replace the battery
- Possible cause 4: The ventilation is not well causing to overheat and shut down.
- Solution: Turn off the connected load device and let the inverter cool for about 15 minutes, remove all the item around the fan and inverter, then keep it in a cool place and restart it for powering a smaller load as required. Possible cause 5: The input voltage is too high
- Solution: Check the status of the charging system and the 12V battery output
- Problem: The output voltage of the inverter is too low
- Possible cause 1: A general voltage meter used for measuring AC power gives a small measurement range
