4. Setup Instructions

Proper connection is crucial for the safe and efficient operation of your inverter. Please follow these instructions carefully.

4.1. Direct Battery Connection

This method is suitable for general car batteries or other DC power sources.

• Voltage Matching: Ensure the input voltage of the inverter (e.g., 12V or 24V) matches the voltage of your battery.
• Parallel Batteries: Multiple batteries can be used in parallel to increase capacity, but ensure the total voltage matches the inverter's input.
• Secure Connection: Connect the inverter's positive (red) terminal to the battery's positive (+) terminal and the inverter's negative (black) terminal to the battery's negative (-) terminal. Ensure good contact.

4.2. Car Cigarette Lighter Connection

This method is for low-power applications in vehicles.

• Inverter Model: Use an inverter model specifically equipped with a car-mounted cigarette lighter plug.
• Power Limit: The cigarette lighter output typically supports electrical appliances with a load of less than 150W. If your appliance exceeds 150W, you MUST use the direct battery connection method (Section 4.1) to avoid damage to your car's electrical system.

4.3. Electric Motorcycle Connection

This method is for connecting to electric motorcycle battery systems.

• Voltage Matching: Electric motorcycle batteries are typically 48V (using four 12V batteries) or 60V (using five 12V batteries). You must select an inverter with an input voltage that matches your electric motorcycle's battery voltage. Refer to the voltage marked on your electric motorcycle.

5. Operating Instructions

Follow these steps to operate your inverter safely and effectively.

1. Ensure the inverter's power switch is in the OFF position before making any connections.
2. Connect the inverter to your chosen DC power source (battery or cigarette lighter) as described in Section 4. Ensure all connections are secure and have good contact.
3. Verify that the power consumption of all electrical appliances you intend to use is within the inverter's rated continuous power range (typically 50% of the peak power). For inductive loads (e.g., refrigerators, motors), ensure their peak starting power does not exceed the inverter's peak power rating.
4. Plug your electrical appliance(s) into the 110V AC output socket(s) of the inverter.
5. Turn ON the power switch of the inverter. The green indicator light should illuminate, indicating normal operation.
6. If the red indicator light illuminates, it signifies that the inverter has entered a protection mode due to overvoltage, undervoltage, overload, or overheating. Refer to the Troubleshooting section for solutions.
7. For car cigarette lighter connections, if the inverter alarms or shuts down due to limited output, start the vehicle's engine or reduce the power consumption of the connected appliances to restore normal operation.

6. Maintenance

Proper maintenance ensures the longevity and optimal performance of your inverter.

6.1. Usage Environment Requirements

• Dry Conditions: Do not immerse the inverter in water or expose it to rain.
• Temperature: Operate the inverter in a cool environment with a temperature between 0°C and 40°C.
• Ventilation: Do not use the power inverter in a narrow, enclosed space. Do not cover the machine during use. Ensure good ventilation around the unit to prevent overheating.

6.2. General Care

• After continuous use, the surface temperature of the inverter casing may rise to approximately 60°C. It is essential to maintain smooth airflow and keep the inverter away from objects susceptible to high temperatures.
• Regularly check all wiring connections to ensure they are tight and free from corrosion.
• Keep the inverter clean and free from dust and debris, especially around the cooling fans.
• This power inverter is prohibited for use by minors.

9. User Tips

Here are some helpful tips based on common user inquiries:

• Battery Compatibility: While the manual specifies lead-acid battery connections, users often ask about LiFePo4 batteries. Always verify the voltage and current capabilities of your LiFePo4 battery management system (BMS) to ensure it can handle the inverter's demands and protection features.
• Household Use: This inverter is designed for converting DC power (from car batteries, solar setups) to AC for various appliances. It can power many household items within its continuous power rating, making it suitable for off-grid, RV, or emergency backup scenarios. It is not intended as a direct replacement for grid power.
• Appliance Startup: For appliances with high starting currents (e.g., refrigerators, motors), turn them on one by one, starting with the lowest peak power device, to prevent overload protection from triggering.
• Cable Sizing: Use appropriately thick cables for battery connections, especially for higher power inverters, to minimize voltage drop and improve efficiency.
