The inverter will either be blue, like this picture here, if it is an SPH15, SPH20 or SPH30. If it is a larger model, like the SPH40 or SHP50 it will be grey.
If you have a Clenergy inverter it is advisable to check it on a regular basis. At least every week would be a good idea.
These inverters have not been the most reliable, so do check.
What you are looking for is to see the blue light on, and the display showing ‘working mode’, like this.
Alternatively, it may show O/P WATT= xxxxW. Just check it is actually making power, and is displaying a number. It is as a fairly common fault on Clenergy inverters to have a blue light and displaying ‘working mode’, but when you look at the watts it isn’t producing any power.
If that is the case, it will look like this.
If the red light is on, you have a problem. Your LED should show a message on it, and this is important.
Here are the list of error codes and what they mean:
|Error Message||What It Means|
|No Utility||Grid voltage is not detected|
|PV Over Voltage||PV voltage is too high|
|DC Bus High||Internal DC bus voltage is too high|
|DC Bus Low||Internal DC bus voltage is too low|
|Over Temperature||Internal temperature is too high|
|Grid Fault||Grid voltage or frequency is out of range|
|Device Fault||Internal fault with inverter circuits|
|Isolation Fault||PV panel ground isolation problem|
|Impedance Fault||Grid impedance fault (or grid disconnected)|
|Ground I Fault||Grid output ground leakage current too high|
|Relay Failure||Grid output relay failure|
|DC INJ High||Grid DC injection too high|
|Ref 2.5V Fault||2.5V reference voltage internal circuit fault|
|DC Sensor Fault||Grid DC current sensor internal fault|
|GFCI Fault||Ground Fault Current Interrupt fault|
|Sci Fault||Internal Master/Slave communication fault|
|Consistent Fault||Internal Master/Slave value mismatch fault|
|CPU Ver Mismatch||Internal Master/Slave firmware incompatible|
|EEPROM Fault||Internal non-volatile memory fault|
|Grid V Mismatch||Internal Master/Slave grid voltage mismatch|
|Grid F Mismatch||Internal Master/Slave grid frequency mismatch|
|Grid Z Mismatch||Internal Master/Slave grid impedance mismatch|
|GFCI Mismatch||Internal Master/Slave ground fault value mismatch|
|DC Curr Mismatch||Internal Master/Slave grid DC current mismatch|

- If your Clenergy solar inverter is over 5 years old, and is broken, you will need a replacement. We recommend either a Fronius or SMA as great replacements. Contact us today with your system details (model of the inverter and the error message) and we can discuss further.
