Important Safety Warnings
- The installation and commissioning of this equipment must be carried out by professional electrical maintenance personnel who are familiar with the device's structure and operational hazards.
- Ensure adequate ventilation and good heat dissipation around the inverter to prevent overheating.
- High voltage is dangerous. Do not open the machine or attempt repairs yourself.
- Always use the original or suitable type of wire to connect the inverter to avoid wire melting due to excessive current.
- The battery voltage must match the inverter's input voltage (12V or 24V). Connecting an incompatible voltage will damage the inverter.
- Do not exceed the rated power of the inverter for the connected load devices.
- Do not connect the inverter with the grid power, and a reverse connection of positive and negative poles is forbidden.
Setup Instructions
1. Initial Inspection and Placement
Before installation, ensure the inverter is free from damage. Place the inverter in a location that allows for smooth ventilation and good heat dissipation. Avoid enclosed spaces or areas with high ambient temperatures.
2. Wiring the Inverter
Connect the inverter to your battery bank using the provided cables. Ensure correct polarity: connect the positive terminal of the inverter to the positive terminal of the battery, and the negative terminal of the inverter to the negative terminal of the battery. Use appropriate wire gauges to prevent overheating and ensure efficient power transfer.
- Step 1: Start by connecting the controller and battery.
- Step 2: Then connect the controller and the PV panels.
- Step 3: Then connect the battery and the inverter.
- Step 4: Finally, let the inverter connect the load.

3. Battery Voltage Matching
The inverter features intelligent recognition of 12V and 24V battery systems. When connected, it will automatically detect the battery voltage and adjust its operation mode accordingly. Ensure your battery system is either 12V or 24V.
- 12V Mode: Input Voltage: 12V, Output voltage: 220V/230V, Rated power: 1500W, Maximum power: 3000W.
- 24V Mode: Input Voltage: 24V, Output voltage: 220V/230V, Rated power: 3000W, Maximum power: 6000W.
4. Output Mode Adjustment (Voltage and Frequency)
The inverter allows for manual adjustment of the output voltage and frequency using internal switches. Refer to the table below for the correct switch combinations:
| Switch 1 | Switch 2 | Switch 3 | Output Mode |
|---|---|---|---|
| OFF | OFF | OFF | 220V 50Hz |
| OFF | ON | OFF | 230V 50Hz |
| ON | OFF | OFF | 240V 50Hz |
| OFF | OFF | ON | 220V 60Hz |
| OFF | ON | ON | 230V 60Hz |
| ON | OFF | ON | 240V 60Hz |
Note: These switches are typically located internally or on a control panel. Consult the physical device for exact switch locations.
Operating Instructions
1. Powering On/Off
Locate the ON/OFF switch on the inverter. Flip the switch to the "ON" position to power on the inverter. The LCD display will illuminate, showing operational parameters. To power off, flip the switch to the "OFF" position.
2. Connecting Devices
Once the inverter is powered on and operating correctly, you can connect your AC-powered devices to the AC output sockets. For charging mobile devices, use the integrated Type-C or USB 5V2.1A ports.
3. Monitoring the Display
The LCD display provides real-time information about the inverter's status:
- Input Voltage: Displays the current DC input voltage from the battery.
- Output Voltage: Shows the AC output voltage.
- Real-time Power: Indicates the current power consumption of connected devices.
- Battery Level: Provides an estimate of the remaining battery charge.
- Output Frequency: Displays the current AC output frequency (50Hz or 60Hz).
- Alarm Identification: Shows icons for various protection statuses (e.g., low voltage, overload, high temperature).
4. Load Considerations
Ensure that the total power consumption of all connected devices does not exceed the inverter's rated power for the current operating mode (1500W for 12V input, 3000W for 24V input). For inductive loads (e.g., refrigerators, washing machines, motors), choose an inverter with a rated power 7-8 times higher than the appliance's power. For resistive loads (e.g., computers, televisions, fans), the instantaneous power can be 10 times its rated power.
Maintenance
1. General Cleaning and Ventilation
Regularly check that the inverter's ventilation openings are clear and free from dust or obstructions. Ensure good airflow around the unit to maintain optimal operating temperature and prevent overheating.
2. Battery Terminal Maintenance
Periodically inspect the battery terminals and inverter connections for corrosion or loose contacts. Clean terminals with a dry cloth if necessary to ensure a secure and efficient connection.
3. Fuse Replacement
If the inverter fails to operate due to a blown fuse (often indicated by reversed polarity connection), replace the fuse with one of the same type and rating. Always disconnect the battery before replacing fuses.
Troubleshooting
1. Alarm Indicators and Protective Functions
The inverter is equipped with several protective functions indicated by alarm icons on the display and/or a buzzer:
| Alarm Icon | Protective Function | Explanation |
|---|---|---|
| LOW | Low voltage protection | Input voltage is below the minimum operating value. |
| T HIGH | Overload protection | The connected load exceeds the inverter's rated overpower. |
| HIGH | High voltage protection | Input voltage is higher than the maximum operating value. |
| 킹 | High temperature protection | The inverter's internal temperature exceeds its maximum tolerance. |
| -50 | Short circuit protection | The inverter detects a short circuit in the load appliance and stops output. |
2. Common Problems and Solutions
- Interference from outside: The inverter may experience interference from strong electromagnetic waves generated by nearby motors, other power inverters, or strong magnetic fields. Try to relocate the inverter or the source of interference.
- Inverter does not respond:
- No connection: Ensure the battery and inverter are properly connected.
- Reversed polarity/blown fuse: Check if the positive and negative poles of the battery are reversed. If so, correct the connection and replace any blown fuses.
- Overload: If the load current exceeds the nominal current, turn off some of the connected loads and restart the inverter.
- Dead battery: The battery may be completely discharged and needs to be charged.
- Low battery voltage or poor contact: Recharge the battery, check the battery terminals for corrosion or looseness, and clean them with a dry cloth if necessary.
