4. Setup

4.1 Unboxing and Contents

Upon opening the package, verify that all components are present and undamaged.

Image: The package contents include the inverter, a 15ft remote controller, one pair of battery cables (red and black, 2.62 ft long), an earth wire, 6 x 40A fuses, and a wrench.

4.2 Battery Connection

Connect the inverter to a 12V DC battery using the provided cables. Ensure the red cable connects to the positive (+) terminal of both the inverter and the battery, and the black cable connects to the negative (-) terminal of both. Secure all connections tightly to prevent arcing and ensure efficient power transfer.

5. Operation

5.1 Powering On/Off

After ensuring all connections are secure, press the power button on the inverter or the remote control to turn the unit on. The LED display will illuminate, showing operational status. To turn off, press the power button again.

5.2 Connecting Appliances

Plug your AC appliances into the inverter's AC outlets. For high-power loads, it is recommended to use the dedicated AC output terminal blocks if available and properly wired. For large inductive or capacitive loads, such as electric tools, it is suggested to turn on the appliance first, then turn on the inverter to allow the soft-start feature to function effectively.

6. Maintenance

• Cleaning: Regularly clean the exterior of the inverter with a dry, soft cloth. Ensure vents and cooling fans are free from dust and debris to maintain optimal airflow.
• Connections: Periodically check all electrical connections (battery terminals, AC outlets, grounding wire) to ensure they are tight and free from corrosion.
• Storage: If storing the inverter for an extended period, disconnect it from the battery and store it in a cool, dry place.
• Battery Health: Maintain your 12V DC battery according to its manufacturer's guidelines to ensure optimal performance and longevity of the inverter system.

7. Troubleshooting

7.1 Common Issues and Solutions

• No Output:
  • Check if the red and black battery cables are correctly linked to the inverter and battery terminals.
  • Ensure the inverter is turned on and the display screen is functioning.
  • Verify that the DC input voltage and AC output voltage values are normal on the display.
• Overload Protection Triggered:
  • The inverter's power output should not exceed its rated continuous power (2500W).
  • Some electrical appliances have a high instantaneous startup power. It is recommended to operate the inverter below approximately 200W of its rated power to avoid overload.
  • Reduce the total wattage of connected appliances.
• Over-temperature Protection:
  • Ensure adequate ventilation around the inverter. Clear any obstructions from the cooling fans.
  • Reduce the load on the inverter.
  • Allow the inverter to cool down before restarting.
• Low Voltage Alarm/Shutdown:
  • This indicates the battery voltage is too low. Recharge the battery.
  • The input under-voltage alarm typically triggers at 10 +/- 0.5V DC, and shutdown at 9.5 +/- 0.5V DC.
• Over-voltage Shutdown:
  • The input over-voltage shutdown triggers at 16 +/- 0.5V DC.
  • Ensure your charging source (e.g., solar charge controller) is regulated and not providing excessive voltage to the battery.

8. Specifications

Please note: While the product title specifies 2500W, the detailed specifications provided are for a 2000W model. Performance characteristics for the 2500W model are expected to be proportionally similar or higher.
