To address this, check the voltage levels from the solar panels and the grid to ensure they are within the specified range. If the voltage levels are consistently high, it may indicate a problem with the solar panels or the grid connection, requiring further investigation and potential adjustments. Inverter-related issues may necessitate professional inspection and repair.
• Under Voltage Fault: Conversely, an under-voltage fault arises when the voltage drops below the inverter's minimum allowable input. This can be triggered by low solar panel output, voltage drops in the wiring, or grid-related problems. Troubleshooting involves verifying that the solar panels are receiving adequate sunlight and that there are no obstructions or shading affecting their performance. Additionally, inspect the wiring for any loose connections or damage that may cause voltage drops. If the issue persists, it may be indicative of a grid problem or an internal fault within the inverter, necessitating further investigation and potential repairs.
• Over Frequency Fault: This fault indicates that the grid frequency is outside the acceptable range. Grid frequency deviations can occur due to imbalances in electricity supply and demand, grid disturbances, or issues with the utility grid. Addressing this fault involves monitoring the grid frequency and ensuring that it remains within the specified range. Inverters are designed to disconnect from the grid if the frequency deviates beyond acceptable limits to prevent damage to the inverter and ensure grid stability. If the over-frequency fault persists, it may be necessary to consult with the utility company to investigate and resolve any grid-related issues.
• Under Frequency Fault: Similar to an over-frequency fault, an under-frequency fault occurs when the grid frequency drops below the acceptable range. This can also result from imbalances in electricity supply and demand, grid disturbances, or problems with the utility grid. Like an over-frequency fault, the inverter will disconnect from the grid to protect itself and maintain grid stability. Resolving this issue typically involves working with the utility company to identify and address any underlying grid problems that may be causing the frequency deviations. Regular monitoring and communication with the utility company can help prevent under-frequency faults and ensure the reliable operation of the solar energy system.
• DC Over Current Fault: This fault is triggered when the direct current (DC) flowing from the solar panels exceeds the inverter's maximum allowable limit. This situation can arise due to excessive solar panel output, wiring issues, or inverter malfunctions. Troubleshooting involves verifying the current levels from the solar panels and ensuring that they are within the specified range. Inspect the wiring for any shorts or damage that may be causing excessive current flow. If the issue persists, it may indicate an internal fault within the inverter, requiring professional inspection and repair. Regular monitoring of DC current levels can help prevent over-current faults and maintain the safety and performance of the solar energy system.

These are just a few of the potential fault codes you might encounter. Always refer to your SOFAR inverter's manual for a complete list and detailed explanations.
