SMA SUNNY TRIPOWER X Solar Inverter
9 fault codes documented
Reconnection fault grid
The inverter cannot connect to the utility grid. This occurs when the selected country standard or a set parameter value does not comply with the local grid requirements, preventing proper grid synchronization.
Insulation error / Check generator
The inverter has detected a ground fault within the PV array. This indicates that the electrical insulation between the PV system and ground is either defective or insufficient, posing a potential safety hazard.
High leakage current / Check generator
A high leakage current is detected in the inverter and/or PV module circuit, indicating a ground fault, residual current, or an internal malfunction. The inverter immediately stops feed-in operation, but automatically attempts to reconnect once the condition is resolved.
Self-diagnosis > Input B defective
The inverter's self-diagnosis has detected a polarity error on input B. This means a PV string connected to input B has incorrect polarity, which can prevent proper operation and potentially damage the inverter.
Fault sensor interior temperature
An internal temperature sensor within the inverter is defective. This fault causes the inverter to interrupt its feed-in operation to prevent potential overheating or damage due to inaccurate temperature monitoring.
Sensor error step-up converter temperature.
A sensor error related to the temperature of the step-up converter has occurred. This issue often results in the inverter's fan operating continuously, potentially indicating an internal anomaly or a faulty sensor reading.
Fault sensor interior temperature
An internal temperature sensor within the inverter is defective. This fault causes the inverter to interrupt its feed-in operation to prevent potential overheating or damage due to inaccurate temperature monitoring.
Self-diagnosis / Device fault
The inverter has detected a general internal device fault through its self-diagnosis routine. This indicates a broad malfunction that prevents normal operation and requires further investigation to identify the specific component or system failure.
