solarking solar inverter error codes

by | Jan 5, 2020

Solar King inverters were installed in Australia a few years ago, and there are still a few out there.  They were available in sizes 1.5kw, 2kw, 3kw, 4kw and 6kw.

If you have a Solar King inverter it is almost certainly out of warranty by now, as there was a 5 year warranty from date of install.

If the red light is lit up, this means the inverter is in fault mode, and there should also be a message in the display window.

Here are the error messages you will get on the inverter, and their meanings:


Error Message Means
Isolation Fault Water of moisture somewhere
Ground I Fault Water of moisture somewhere
Grid Fault Error with grid power
Impedence Fault Error with grid power
No Utility No power from grid/AC breaker off
PV Over Voltage Broken
Consistent Fault or Mismatch Broken
DC Bus High Broken
DC Bus Low Broken
Device Fault Broken
Over Temperature Broken
Relay Failure Broken
Grid V Mismatch Broken
GFCI Fault Broken
DC Inj High Broken
Ref 2.5V fault Broken
DC Sensor Fault Broken
SCI Fault Broken
EEPROM Fault Broken
PAC=0 + Blue light on Broken
BLANK SCREEN NO LIGHTS Either no DC from panels or broken

Always try rebooting your inverter first, sometimes this will clear an error message and you may find the inverter will continue on working for a while longer. Not sure how to do this? Check here.
