Excessive Ground Leakage Current Trip
Alarm 2064 triggers when the inverter's internal Residual Current Monitoring Unit (RCMU) detects continuous or surging leakage current (Idc/Iac) to protective earth exceeding safety thresholds (typically >300 mA surge or sustained >30 mA difference), characteristic of parasitic capacitance discharge or isolation degradation in transformerless topologies.
