The codes that start with F- are usually caused by the power from the street (the grid) being outside the Sharp JH1600e Solar Inverter’s operating parameters. The inverter codes beginning with P specify that the voltage coming from the solar panels is outside the inverter parameters. The error that starts with E- signifies a more serious error. If this continues it changes to a d code. When this happens, a manual shutdown procedure is necessary.

If your Sharp JH1600e Solar Inverter is still within the warranty period you can contact the equipment installer or supplier should the error persists. If your inverter is outside the warranty period we suggest that you contact a professional solar power expert.
