After the inverter reports an alarm, the method for locating the fault position is as follows: Connect a single string of photovoltaic modules to the inverter, power on the inverter for startup detection, and determine the fault location based on the alarm information reported by the FusionSolar App.
If any issues arise with the inverter, prioritizing safety and adhering to industry standards becomes imperative. Only trained electricians are authorized to conduct diagnostic and repair work on both the solar power plant and the inverter.
The management system generates the 2001 String High Voltage alarm. FusionSolar app: On the Device tab page, select an inverter and select the Alarm Info. FusionSolar Web: On the Monitor tab page, select an inverter and select the Alarms. The PV array is not properly configured.
The inverter generates a 2039 alarm. The management system indicates that the inverter is shut down. The grid voltage drops sharply or a short circuit occurs, causing the inverter to output an excessive current momentarily and triggering protection. A high-power load is connected on the transformer side.
Symptoms On the landing page, the following alert appears under the Powerwall+ / Tesla Solar Inverter: "Rapid Shutdown Initiated. Check AC breaker and low-voltage rapid shutdown circuit".
