How to solve Error Code 43

Fault code:【43】Communication output mode - Setting item incorrectReason:1. Parameter setting error: AC output frequency, voltage amplitude, and other parameters were not set correctly, resulting in the output not meeting the grid standards.  2. Mode switching logic error: The inverter did not correctly recognize the load type, resulting in a mismatch between the output mode and the actual demand.  3. Communication failure: Communication between the upper computer and the inverter control board is abnormal, resulting in command transmission errors.  Solution:1. Check parameter settingsUse a multimeter to measure the actual output voltage and frequency, and confirm if they are within the allowable range.  Adjust the internal parameters of the inverter according to the instruction manual to ensure compliance with local power grid standards.  2. Restart the deviceTemporary system errors can be resolved by shutting down and restarting, restoring factory settings, and reconfiguring parameters.  3. Check communication connectionConfirm that there is no conflict between the touch screen IP address and the control board IP address, and that the network cable connection is normal.  Restart the communication module between the upper computer and the inverter, and synchronize the data again.  4. Contact technical supportIf self inspection is ineffective, it is necessary to contact the inverter manufacturer or a professional electrician to detect internal program or hardware faults.  Note: Please do not dismantle the machine without permission, otherwise it will be out of the warranty of Ktech.
