1124 Low Insulation Impedance Fault (en)
1. Check impedance between PV array output and PE, and eliminate short circuits and poor insulation points.
2. Check that inverter PE cable is correctly connected.
3. If sure that impedance is less than default threshold in cloudy/rainy environment, contact the distributor or FoxESS support. To reset the 'Insulation Resistance Threshold Setting'.
