K-star inverters

If your inverter is less than 5 years old, there’s a good chance you still have warranty (assuming the manufacturer is still in business).
Not sure if the inverter is faulty, or if it is actually reporting a fault elsewhere in your solar system?

See below for the error codes recognized with your K-Start inverter/solar system.

If you are still unsure call us to see if we can help you over the phone, or book in a Solar Health check.
You could save big $$$’s with one of our Solar accredited teams expert appraisal. 
If you believe that your Inverter may be subject to an Insurance claim please contact us on 07 3274 4365 and advise us of the details

Trouble Shooting

It is very easy for the inverter’s maintenance. When you meet any problems, please refer to the following trouble shooting first, please contact your local distributor if the problem can’t be solved by yourself.
The following sheet lists some basic questions may encounter in the operation.

Trouble Shooting
  Alarm Message Solution
System Faulty Or Failure Type AC voltage & frequency are too high or too low.
(F00-F03)
  1. Pease check mains voltage whether it is complied with local,safety standard
  2. Please check the AC output line is properly connected. Make sure its output voltage to see if it is normal.
  3. Disconnect PV input and restart the inverter and check whether fault still exists.
  4. Contact with your local distributor if the fault still exists.
Bus voltage is too high or too low
(F04-F05)
  1. Please check the setting of input mode
  2. Disconnect PV input and restart the inverter and check whether fault still exists.
  3. Contact with your local distributor if the fault still exists.
Bus voltage is Unbalance(F06)
  1. Please check the setting of input mode.
  2. Disconnect PV input and restart the inverter and check whether fault still exists.
  3. Contact with your local distributor if the fault still exists.
Insulation impedance Fault(F07)
  1. Disconnect PV input and restart the inverter and check whether fault still exists.
  2. Please measure impedance of PV+/PV- to ground whether is over than 500KΩ.
  3. Please contact your local distributor if impedance is less than 500KΩ.
Input Current High
(F08)
  1. Please check the setting of input mode.
  2. Disconnect PV input and restart the inverter and check whether fault still exists.
  3. Contact with your local distributor if the fault still exists.
Hardware Current High(F09)
  1. Disconnect PV input and restart the inverter after few minutes and check whether fault still exists.
  2. Contact with your local distributor if the fault still exists.
Inverter Current High (F10)
  1. Disconnect PV input and restart the inverter after few minutes and check whether fault still exists.
  2. Contact with your local distributor if the fault still exists.

 

Inverter DC Current high (F11)
  1. Disconnect PV input and restart the inverter after few minutes and check whether fault still exists.
  2. Contact with your local distributor if the fault still exists.
Amb Temperatur Over(F12)
  1. Disconnect PV input and cool down the inverter then restart the inverter to see if it is back to normal operation.
  2. Please check environmental temperature whether out of working temperature.
  3. Contact with your local distributor if the fault still exists.
Heatsink Temperature High(F13)
  1. Disconnect PV input and cool down the inverter then restart the inverter to see if it is back to normal operation.
