Known Growatt inverter faults
No AC Connection: make sure your solar supply main switch hasn’t tripped, and turn it on if need be.
AC V Outrange: the voltage of the grid is possibly outside the inverter parameters, which will work again once it is back in range. If this error is on often, check the quality of your electricity with your provider in order to make sure your voltage remains under 255 V.
Error 117: this fault code indicates a relay issue; it means that the inverter needs to be replaced.
Any other “Error” message might be fixed by resetting the system. If this doesn’t work, it is likely that your inverter will need a replacement. If it is still under warranty, you will be asked to provide photos of the unit’s screen showing the error message and serial details. If the inverter is no longer covered by warranty, you will have to replace the unit.
