CODE Error 201 Severity: High Difficulty: Intermediate

Transient Leakage Current Fault

Error 201 indicates the internal Residual Current Monitoring Unit (RCMU) detected an excessive transient leakage current (residual current spike typically >30mA or sudden jump >30mA to ground) exceeding safety limits defined in DIN VDE 0126-1-1 / IEC 62109-2, causing the inverter to immediately disconnect from the grid.

CODE Error 407 Severity: High Difficulty: Intermediate

Auto Test PV Isolation Low

Error 407 triggers when the inverter's internal diagnostic test detects that the insulation resistance between the DC PV array conductors and earth is below the safety threshold (typically <50 kΩ or standard local limit), preventing grid synchronization to avoid electrical shock or ground-fault fires.
