SMA · SUNNY TRIPOWER X Solar Inverter
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.
Click steps to track your progress.
Verify inverter diagnostic logs for additional fault codes or specific temperature values related to the step-up converter.
Inspect the step-up converter's cooling fins and ventilation openings for dust, debris, or obstructions that could impede airflow.
Measure the ambient temperature around the inverter and compare it with the manufacturer's specified operating range.
Check the real-time temperature readings for the step-up converter via the inverter's display or monitoring system to confirm plausibility.
Inspect all visible wiring connections related to the step-up converter and its temperature sensor for looseness or damage.
