2. Important Safety Instructions
Failure to follow these instructions may result in serious injury, property damage, or death. Always exercise extreme caution when working with electrical systems.
- Proper Installation: Ensure all connections are secure and correctly polarized. Incorrect wiring, especially reverse polarity, can cause severe damage to the inverter and connected devices, and poses a fire risk.
- Ventilation: Install the inverter in a well-ventilated area. Do not block the cooling fans or vents. Overheating can lead to reduced performance or failure.
- Environment: Avoid installing the inverter in areas exposed to direct sunlight, heat sources, moisture, or flammable materials.
- Battery Compatibility: This inverter is designed for 12V DC battery systems. Do not connect it to 24V or other voltage systems unless specified for a different model.
- Load Capacity: Do not exceed the inverter's continuous power rating of 3000W. Overloading can cause the inverter to shut down or be damaged. Pay attention to surge power requirements of appliances.
- Grounding: Ensure the inverter is properly grounded according to local electrical codes.
- Fuse Protection: Always use appropriate external fuse protection on the DC input side to protect against overcurrent.
- Children and Pets: Keep the inverter and all electrical connections out of reach of children and pets.
- Emergency Procedures: In case of smoke, unusual odors, or fire, immediately disconnect the power source and evacuate the area.

5. Setup & Installation
Proper installation is critical for the safe and efficient operation of your inverter. Follow these steps carefully:
5.1 Choosing an Installation Location
- Mount the inverter on a flat, stable surface.
- Ensure adequate ventilation around the inverter. Do not obstruct the cooling fans.
- Keep the inverter away from direct sunlight, heat sources, water, and flammable materials.
- The inverter should be as close as possible to the battery bank to minimize cable length and voltage drop.
5.2 Connecting to a 12V DC Battery
WARNING: Before making any connections, ensure the inverter's power switch is in the OFF position and no AC loads are connected.
- Identify the positive (red) and negative (black) terminals on both the inverter and your 12V DC battery.
- Connect the red battery cable to the positive (+) terminal of the inverter. Secure tightly.
- Connect the other end of the red battery cable to the positive (+) terminal of your 12V DC battery. Secure tightly.
- Connect the black battery cable to the negative (-) terminal of the inverter. Secure tightly.
- Connect the other end of the black battery cable to the negative (-) terminal of your 12V DC battery. Secure tightly.
- Ensure all connections are firm to prevent loose contacts, which can cause overheating and potential fire hazards.

5.3 Connecting the Remote Control
Plug the remote control cable into the designated remote control port on the front panel of the inverter. The remote allows you to turn the inverter ON/OFF from a distance.
5.4 Solar System Integration (Optional)
For off-grid solar systems, connect the inverter to a 12V deep cycle battery bank, which is charged by solar panels via a charge controller. Ensure the charge controller is properly configured for your battery type and solar panel array.

6. Operating Instructions
6.1 Turning the Inverter ON/OFF
- Ensure all DC connections are secure.
- Press the main power switch on the inverter's front panel to the "ON" position, or use the remote control switch.
- The LCD display will illuminate, showing the input DC voltage and output AC voltage. The indicator light should be green.
- To turn off, press the main power switch or remote control switch to the "OFF" position.
6.2 Connecting AC Appliances
Once the inverter is on and operating normally (green indicator light), you can connect your AC appliances to the 110V/120V AC outlets.
- Always check the wattage requirements of your appliances. The total continuous wattage of all connected appliances must not exceed 3000W.
- For appliances with motors (e.g., refrigerators, power tools), consider their surge power requirements, which can be significantly higher than their continuous running wattage. The inverter has a 6000W peak power capacity.
- Plug appliances directly into the AC outlets on the inverter.
- For USB charging, connect your device to the 3.1A USB port.

6.3 Understanding Pure Sine Wave Output
This inverter produces a pure sine wave output, which is identical to the AC power supplied by your utility company. This makes it suitable for sensitive electronics, medical equipment (like CPAP machines), and appliances with motors, ensuring they run smoothly and efficiently without damage.
7. Maintenance
Regular maintenance helps ensure the longevity and optimal performance of your inverter:
- Cleaning: Periodically clean the exterior of the inverter with a dry, soft cloth. Do not use liquids or abrasive cleaners.
- Ventilation: Ensure the cooling vents and fans are free from dust and debris. Blocked vents can lead to overheating.
- Connections: Regularly check all DC and AC connections to ensure they are tight and free from corrosion. Loose connections can cause voltage drops and overheating.
- Storage: If storing the inverter for an extended period, disconnect it from the battery and store it in a cool, dry place.
