1. Introduction
The Green Cell INV18 Power Inverter is a device designed to convert direct current (DC) voltage from a car battery or other 12V/24V DC source into alternating current (AC) ~230V, identical to the power found in standard European wall sockets (Type E). This inverter is an ideal solution for individuals who require power on the go, whether traveling by car, camping, or operating a truck, especially in locations without direct access to conventional power outlets.
It allows you to power various electronic devices, including laptops, refrigerators, and TV sets. Additionally, it features a USB port for charging smaller gadgets like smartphones and tablets. The INV18 inverter is engineered with advanced safety features and certifications to ensure reliable and secure operation of your connected devices. Its pure sine wave output makes it suitable for even the most sensitive electronics, such as solar panels and certain heating systems.
2. Safety Information
Please read and understand all safety instructions before operating the inverter. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Ventilation: Ensure adequate ventilation around the inverter. Do not block ventilation openings. Overheating can cause the inverter to shut down or be damaged.
- Environment: Do not expose the inverter to water, rain, snow, spray, or any liquids. Keep it away from flammable materials, gases, or vapors. Operate in a dry, well-ventilated area.
- Connection: Connect the inverter only to a 12V or 24V DC power source as specified. Incorrect voltage can damage the inverter and connected devices. Ensure correct polarity when connecting to the battery.
- Load: Do not exceed the inverter's rated continuous power output (1000W). Overloading can cause the inverter to shut down or be damaged.
- Maintenance: Do not attempt to open, disassemble, or modify the inverter. There are no user-serviceable parts inside. Refer all servicing to qualified service personnel.
- Children: Keep the inverter out of reach of children.
- Grounding: Ensure the inverter is properly grounded according to local electrical codes.

4. Setup
Follow these steps to properly set up your Green Cell INV18 Power Inverter:
- Choose a Location: Select a dry, well-ventilated area for the inverter. Ensure there is sufficient space around the unit for air circulation, especially around the cooling fan. Avoid placing it in direct sunlight or near heat sources.
- Prepare Power Source: Ensure your 12V or 24V DC battery (e.g., car battery) is fully charged and capable of providing the necessary current. Turn off the vehicle engine if connecting to a car battery to prevent accidental starting.
- Connect DC Cables:
- Connect the red positive (+) cable to the positive (+) terminal on the inverter.
- Connect the black negative (-) cable to the negative (-) terminal on the inverter.
- Connect the other end of the red positive (+) cable to the positive (+) terminal of your DC power source.
- Connect the other end of the black negative (-) cable to the negative (-) terminal of your DC power source.
- Grounding (Optional but Recommended): If available, connect a grounding wire from the inverter's grounding screw to a proper earth ground point (e.g., vehicle chassis).
- Initial Check: Before turning on, double-check all connections for correct polarity and tightness.
5. Operating Instructions
Once the inverter is properly set up, follow these steps to operate it:
- Power On: Press the ON/OFF button on the inverter. The power indicator light should illuminate, indicating the inverter is active.
- Connect AC Devices: Plug your AC-powered devices into the 230V AC output socket on the inverter. Ensure the total continuous power consumption of all connected devices does not exceed 1000W. For devices with high startup current (e.g., motors, compressors), ensure their surge power requirement does not exceed 2000W.
- Connect USB Devices: Plug your USB-powered devices into the USB port for charging.
- Monitor Operation: Observe the inverter and connected devices during operation. If the power fault indicator illuminates or the inverter emits an alarm, refer to the Troubleshooting section.
- Power Off: When you are finished using the inverter, first disconnect all AC and USB devices. Then, press the ON/OFF button to turn off the inverter. Finally, disconnect the DC cables from the battery.
Note: For optimal battery life and inverter performance, avoid continuously drawing power close to the maximum rated output.
6. Maintenance
Regular maintenance helps ensure the longevity and reliable operation of your Green Cell INV18 Power Inverter.
- Cleaning: Periodically clean the exterior of the inverter with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the inverter is turned off and disconnected from all power sources before cleaning.
- Ventilation: Regularly check that the cooling fan and ventilation openings are free from dust, dirt, and obstructions. A blocked fan can lead to overheating.
- Connections: Periodically inspect the DC input cable connections to ensure they remain tight and free from corrosion. Loose connections can cause voltage drops and heat buildup.
- Storage: When not in use for extended periods, store the inverter in a cool, dry place, away from direct sunlight and extreme temperatures.
