inverter fault

[varris]

Hi, What sort of fault does the code SPS stand for

[Dave Foster]

I'm not familiar with that fault code, it appears to be a solar only inverter fault code - the manual says to turn off the PV, and the grid and then restart it again (grid on, PV on) which should clear it - if not contact FoxESS support.

I've already switched the inverter off and on as per the manual and it is back to normal operation, what I want to know is what caused the fault in the first place.
