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:
|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|
|Grid V Mismatch||Broken|
|DC Inj High||Broken|
|Ref 2.5V fault||Broken|
|DC Sensor 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.
