What should I do if my KStar KSG-20K displays Inverter DC Current high (F11)?
If your KStar Inverter is showing an 'Inverter DC Current High' error, disconnect the PV input and restart the inverter after a few minutes to see if the fault clears. If the issue continues, contact your local distributor.
What to do if my KStar KSG-20K Inverter shows 'Ambient Temperature High' (F12)?
If your KStar Inverter displays error code F12, indicating a high ambient temperature, take these steps: 1. Disconnect the PV input and allow the inverter to cool down. Then, restart the inverter to see if normal operation resumes. 2. Check the environmental temperature to ensure it is within the specified working range. 3. If the fault persists, contact your local distributor for further assistance.
How to resolve Heatsink Temperature High (F13) error on KStar KSG-20K Inverter?
If you're seeing a 'Heatsink Temperature High' error (F13) on your KStar Inverter, follow these steps: 1. Disconnect the PV input and allow the inverter to cool down before restarting it to see if it returns to normal operation. 2. Verify that the environmental temperature is within the recommended working range. 3. If the problem persists, contact your local distributor.
What should I do if my KStar KSG-20K displays 'Bus Voltage Abnormal' (F06)?
If your KStar Inverter is showing a 'Bus Voltage Abnormal' error (F06), try the following: 1. Check the setting of input mode. 2. Try restarting the inverter every few minutes, several times, to see if the fault clears. 3. If the fault persists, contact your local distributor for assistance.
What does 'Insulation impedance Fault' (F07) mean on my KStar Inverter?
If your KStar Inverter is showing an 'Insulation impedance Fault' (F07), try the following steps: 1. Disconnect the PV input and restart the inverter to see if the fault clears. 2. Measure the impedance of PV+/PV- to ground to ensure it is above 500KΩ. 3. If the impedance is less than 500KΩ, contact your local distributor.
What should I do if my KStar KSG-20K displays Input Current High (F08)?
If your KStar Inverter is showing an 'Input Current High' error, check the setting of the input mode. Disconnect the PV input and restart the inverter to see if the fault clears. If the issue continues, contact your local distributor.
What to do if my KStar KSG-20K Inverter shows a system faulty or failure type error?
If your KStar Inverter displays a system fault or failure, it could be due to several reasons: * AC voltage and frequency being too high or too low (F00-F03): Check if the mains voltage complies with local safety standards and ensure the AC output line is properly connected. Verify its output voltage. * Bus voltage being too high or too low (F04-F05): Verify the setting of the input mode. * Bus Voltage Abnormal (F06): Check the setting of input mode. * Insulation impedance Fault (F07): Measure the impedance of PV+/PV- to ground; it should be over 500KΩ. For all these issues, you can try disconnecting the PV input, restarting the inverter, and checking if the fault persists. If problems continue, contact your local distributor.
What to do if my KStar Inverter indicates a Heatsink Temperature High (F13)?
If your KStar Inverter is showing a 'Heatsink Temperature High' error, first, disconnect the PV input and allow the inverter to cool down. Then, restart it to see if normal operation resumes. Also, check the environmental temperature to ensure it is within the specified working range. If the problem persists, contact your local distributor.
What to do if KStar KSG-20K Inverter displays 'Leakage Current High' (F20)?
If your KStar Inverter displays 'Leakage Current High' (F20), here’s what you should do: 1. Disconnect the PV input and restart the inverter to see if the fault clears. 2. If the fault persists, contact your local distributor.
How do I fix an AC Relay Fault (F14) on my KStar Inverter?
If your KStar Inverter is showing an AC Relay Fault (F14), try these steps: 1. Disconnect the PV input and restart the inverter to see if the fault clears. 2. If the fault persists, contact your local distributor.
