5.2. Battery Connection (DC 24V)
- Ensure the inverter's power switch is in the OFF position.
- Connect the red positive (+) battery cable to the positive (+) terminal of your 24V battery bank.
- Connect the other end of the red positive (+) cable to the positive (+) DC input terminal on the inverter.
- Connect the black negative (-) battery cable to the negative (-) terminal of your 24V battery bank.
- Connect the other end of the black negative (-) cable to the negative (-) DC input terminal on the inverter.
- Tighten all connections securely to prevent loose contacts, which can cause overheating and damage.
5.3. Grounding the Inverter
For safety, the inverter must be properly grounded. Connect the provided ground wire from the inverter's ground terminal to a suitable earth ground point (e.g., vehicle chassis, ground rod, or electrical panel ground bus).
5.4. Remote Control Connection
The remote control allows for convenient power management, especially when the inverter is installed in a less accessible location. Plug the remote control cable into the designated REMOTE port on the inverter. The remote control features an ON/OFF button and a battery level indicator.

6. Operating Instructions
6.1. Powering On/Off
- After all connections are secure, switch the inverter's main power switch to the ON position. The LCD display will illuminate.
- Alternatively, use the ON/OFF button on the remote control to power the inverter on or off.
- To power off, switch the main power switch to OFF or press the remote control's ON/OFF button.
6.2. Connecting AC Loads
- Plug your AC appliances into the 110V/120V AC outlets on the inverter.
- Ensure the total continuous wattage of all connected appliances does not exceed 5000 watts.
- For appliances with high startup (surge) power requirements, ensure the inverter's 10000-watt peak capacity is not exceeded.
6.3. USB Port Usage
The inverter includes a 2.1A USB port for charging compatible USB-powered devices such as smartphones and tablets.
6.4. Interpreting the LCD Display
The LCD display provides critical information for monitoring the inverter's performance:
- Input Voltage (DC IN): Shows the current DC voltage from your battery bank.
- Battery Capacity: Indicates the estimated remaining battery charge level.
- Power Percentage: Displays the percentage of the inverter's capacity currently being used.
- Time of Use: Shows the duration the inverter has been operating.
- Power Indicator Light: Illuminates when the inverter is active.
- Fault Indicator (ERROR): Displays error codes or warnings if a protection feature is triggered.
- Output Power: Shows the current AC power output in watts.
- Output Frequency (FREQUENCY): Displays the AC output frequency (60Hz).
- Operating Temperature (TEMPERATURE): Shows the internal temperature of the inverter.
7. Maintenance
- Cleaning: Periodically clean the exterior of the inverter with a dry cloth. Ensure ventilation openings and cooling fans are free from dust and debris.
- Connections: Regularly check all DC and AC connections to ensure they are tight and free from corrosion.
- Ventilation: Confirm that the inverter's ventilation remains unobstructed during operation.
8. Troubleshooting
If the inverter is not functioning correctly, consult the LCD display for error messages and refer to the following common issues:
| Problem | Possible Cause | Solution |
|---|---|---|
| No AC Output / Inverter Off | Low battery voltage, Overload, Overheat, Loose connections, Inverter switch off | Check battery voltage, Reduce load, Allow inverter to cool, Secure all cables, Turn inverter on |
| LCD shows "ERROR" | Specific fault detected (e.g., overvoltage, undervoltage, overload, short circuit, overheat, reverse polarity) | Identify the specific error code on the display. Address the underlying issue (e.g., charge battery, reduce load, check wiring). The inverter may require a power cycle (disconnect and reconnect battery) after a fault. |
| Weak or Intermittent Power | Insufficient battery charge, Undersized battery cables, Loose connections | Charge battery, Use appropriate gauge cables, Tighten connections |
| Fans constantly running | High internal temperature due to heavy load or poor ventilation | Ensure adequate ventilation, Reduce load if possible. This is normal operation under heavy load. |
