Faulty Clenergy Inverter

by | Mar 31, 2021

Clenergy inverters were installed quite extensively in South Australia."<yoastmark

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.clenergy-solar-inverter-zero-watts

Here are the list of error codes and what they mean:

Next Steps

  • Your Clenergy solar inverter only had a 5 year warranty (from the date of the first install, not any warranty replacements), so if it is broken, you will need a replacement. We recommend either an SMA or Goodwe as great replacements.  Contact us today with your system details (model of the inverter and the error message) and we can discuss further.
