Usage Features:
Connection Instructions:
- Battery Connection: Connect the clip cable to a 12V DC battery. Ensure the battery type and voltage match the inverter's requirements. Connect the red clip to the positive terminal and the black clip to the negative terminal to avoid blowing the fuse due to reverse connection. Only 12V batteries are allowed; 6V batteries are not.
- Load Connection: Connect the desired load to the AC output socket or USB port.
- Power On: Press and hold the power switch button for 1 second to start the inverter.
- Power Off/Storage: When not in use, disconnect the clip cable from both ends of the battery to prevent static power loss.
Operation Guide:
- Starting Up: After a 1-second long press of the switch, the socket outputs 220VAC. Connect your load to the AC output socket or USB port.
- Overload Protection: If the load power exceeds the rated power, the inverter will automatically shut down due to overload protection. Reduce the load and restart the product.
- Under-voltage Protection: When the battery voltage drops to 10V, the under-voltage protection activates, and the product shuts down automatically. This protects the battery from damage and ensures sufficient power for car starting.
- Over-temperature Protection: If the operating temperature exceeds the safe limit due to poor ventilation or high external temperature, the over-temperature protection activates, and the product shuts down. It will automatically resume operation once the temperature returns to normal.
- Overvoltage Protection: If a faulty battery charging system causes the battery voltage to rise above 18.5V, the overvoltage protection activates, and the product shuts down automatically.
- Caution: Although the product has overvoltage protection, input voltages exceeding 17V may still cause damage.
Maintenance Features (Troubleshooting):
Problem: No output and abnormal power display light
- Possible Causes:
- Battery defects.
- Loose battery clips.
- Measures:
- Check the battery and replace it if necessary.
- Check the connections.
Problem: Output voltage is too low
- Possible Causes:
- A standard average AC voltmeter measuring the output voltage will show an error of 5 to 15V.
- Battery voltage is too low.
- Measures:
- The inverter outputs a "pure sine wave," requiring measurement with a voltmeter marked "true RMS" or an oscilloscope capable of measuring RMS values.
- Charge the battery.
Problem: Product does not work
- Possible Causes:
- Load power exceeds the continuous output power, triggering overload protection shutdown.
- Load power is lower than the rated power, or capacitive/inductive load has too high a power-on surge, causing overload protection shutdown.
- Product overheats due to poor ventilation, triggering over-temperature protection shutdown.
- Battery feed issue.
- Measures:
- Use a load no greater than the rated one.
- If the start-up surge of the load exceeds the inverter's starting capacity, choose a suitable 220V power supply.
- Unplug the inverter from the output socket, allow it to cool for 15 minutes, and remove any obstructions. Move the product to a cooler location. If continuous operation is necessary, reduce the load and restart.
- Recharge the battery.
