Learn how to troubleshoot and resolve Growatt Error Code 101 related to datalogger communication faults.
Error Code 101 typically indicates a communication issue between the inverter and the datalogger. This can be caused by wiring problems or configuration errors.
You can check the datalogger connection by inspecting the wiring and ensuring all connections are secure. Additionally, verify the settings in the monitoring software.
Error 101 typically indicates a communication fault between the inverter and the datalogger. The inverter relies on a stable communication link to relay performance data and receive operational commands. This fault may arise due to issues such as a break in the communication cable, which can disrupt the signal transmission. The inverter's operational logic includes periodic checks for the datalogger's presence; if it fails to receive a response, it triggers the fault code. Furthermore, firmware discrepancies can lead to compatibility issues, prompting the inverter to flag a communication error.
Users may observe flashing LEDs on the inverter indicating a fault, along with a notification in the monitoring app that displays 'Error 101'. Additionally, there may be a drop in energy production metrics, suggesting that the inverter is not properly communicating with the datalogger.
Always consult a licensed electrician or certified solar installer for troubleshooting and repairs to ensure compliance with local electrical codes and safety standards.
To avoid future occurrences of Error 101, ensure that all wiring is secured and protected from environmental factors. Regularly inspect communication cables for wear and tear, and keep firmware updated to the latest version. Additionally, maintain a clear area around the inverter and datalogger to minimize electrical interference.
