1. Introduction
This manual provides essential information for the safe and efficient operation of your Green Cell 1500W/3000W Pure Sine Wave Car Power Inverter. This device converts 12V DC power from your vehicle's battery into 230V AC power, suitable for a wide range of electronic devices. It delivers a continuous output of 1500W and a peak power of 3000W. Please read this manual thoroughly before use and retain it for future reference.
2. Safety Instructions
Always observe the following safety precautions to prevent injury or damage to the inverter and connected devices:
- Do not open the inverter casing. There are no user-serviceable parts inside.
- Ensure proper ventilation around the inverter. Do not block cooling vents.
- Keep the inverter away from water, moisture, and flammable materials.
- Connect the inverter only to a 12V DC power source. Connecting to a 24V or higher source will damage the unit.
- Ensure the total power consumption of connected devices does not exceed the inverter's continuous output rating (1500W).
- Always connect the inverter to the battery terminals using the provided cables. For power exceeding 150W, avoid using the cigarette lighter socket.
- Disconnect the inverter from the power source when not in use.
- This inverter produces a pure sine wave output, making it suitable for sensitive electronics like laptops, medical equipment, and power tools.

5. Setup
Follow these steps to properly set up your inverter:
- Placement: Choose a dry, well-ventilated location for the inverter, away from direct sunlight, heat sources, and flammable materials. Ensure sufficient space around the unit for airflow.
- Battery Connection:
- Ensure the inverter is switched OFF.
- Connect the red cable to the positive (+) terminal of the inverter and then to the positive (+) terminal of the 12V battery.
- Connect the black cable to the negative (-) terminal of the inverter and then to the negative (-) terminal of the 12V battery.
- Ensure all connections are tight and secure. Loose connections can cause overheating and damage.
- Grounding (Optional but Recommended): For enhanced safety, connect a ground wire from the inverter's ground screw to a suitable vehicle chassis ground point.
