Below is a list of common fault alarm codes for your Clenergy Solar Inverter Model Number SPH15/SPH20/SPH30/SPH40 and SPH60, followed by helpful solutions

Fault ReadingsSolutions
No UtilityCheck grid voltage by multi-meter, check grid connection and check breaker between inverter and grid
Grid FaultCheck grid voltage and frequency by multi-meter
Impedance FaultCheck the wires between inverter and grid
Isolation FaultCheck the impedance between PV+ and PV- and earth ground
Ground I FaultCheck the AC wiring and connection system
Over TemperatureReduce ambient temperature
PV Over VoltageCheck the PV open-circuit voltage – should be less than 500Vdc
Device FaultDisconnect PV+ and PV- from the input and start up the unit again
Consistent or Mismatch FaultDisconnect PV+ and PV- from the input and start up the unit again

  • 50% of the time it’s a quick easy fix for any solar tech…
  • Error messages and fault codes that are due to an external fault elsewhere in the solar system.
  • The solar system is tricking the inverter into thinking it has that error or fault.
  • External faults are relatively easy to find and repair. Once fault is repaired, the inverter is back online.
  • Other 50% of the time
  • There is a fault, which requires more diagnostic type of testing to locate the fault. Out of these about 1 in 4 can be solved onsite. Things like a dodgy install or water damage somewhere.
  • The rest of the time it’s the inverter that’s the problem. 1 out of every 2 times the inverter can be sent away for repairs or we can organise those repairs under warranty with the manufacturer, and…
  • The rest of the time the inverter was of low quality and either not fixable of not good value to fix. If this is the case we would quote on an inverter with similar specs to replace it with. Getting your system back online fast with high quality parts.
  • In the worst case scenario, rare ground leakage faults are very difficult to find and fix but we have also had experience locating these aswell.
Be careful some dodgy solar guys will just say you need a new inverter without performing any tests just so they can sell you a new inverter that you may not even need!
