Pure sine wave inverters are devices that convert DC (direct current) power into AC (alternating current) power with a clean, stable, and sinusoidal waveform. They are used in applications where high-quality, stable power is required, such as in sensitive electronic devices and solar power systems. The inverters are designed to produce a waveform that closely resembles the sine wave of grid power, which means they are better suited for powering most AC appliances and devices than modified sine wave inverters. Even though pure sine wave inverters are designed to provide stable and clean power, they can sometimes experience issues that can affect their performance. Here are some common problems and their troubleshooting solutions:
Potential issues:
Defective battery: Inspect the battery and replace if required.
Reverse connection: Ensure the correct polarity of the battery connection.
Loose connection: Verify the connections and secure the terminals.
Possible causes:
Voltage drop across DC cables: Utilize shorter or thicker DC cables. Verify if the battery is fully charged.
Battery incompatibility. Confirm that you are using a lead-acid (AGM, GEL, and flooded batteries) battery or LiFePO4 battery that is compatible with the inverter.
Probable reasons:
AC product's power consumption surpasses the capacity. Install a bigger battery to fulfill the increased power demand.
Battery is old or faulty. Replace the battery with a new one.
Inadequate battery charging. Verify the battery charging procedure.
Power dissipation in DC cables. Employ shorter or thicker DC cables.
The illumination of the fault LED on your inverter may be triggered by different factors. For detailed instructions on how to address this issue, please consult the user manual.
Possible reasons:
Input voltage falls below the specified level. Maintain input voltage above the minimum threshold (refer to the user manual).
Input voltage exceeds the maximum threshold. Keep input voltage below the specified limit (refer to the user manual).
Inverter overheating. Allow the inverter to cool down, ensure proper ventilation, and decrease the load on the inverter to avoid high temperature.
Operating equipment consumes excessive power. Use a higher wattage inverter or employ a lower power device.
Inverter is short-circuited. Disconnect the inverter, switch off the ON/OFF button to reset. After resetting, turn on the switch.
A pure sine wave inverter is an essential component of off-grid solar systems. However, it can encounter problems that may affect its performance and reliability. By following the troubleshooting steps outlined in this guide, you can identify and resolve common issues with your pure sine wave inverter. Remember to always refer to the user manual for specific instructions and seek professional assistance from our customer service center if necessary.
