How to solve Error Code 41

Fault code:【41】Parallel wiring faultReason:1. wiring errorIf the positive and negative poles of the DC input line are reversed, it will trigger the built-in reverse protection. 2. Insulation issuesComponent edge burning: Black spots on the edge of the component may cause electrical leakage in the frameJoint immersion/short circuit3. Abnormal voltageBus voltage fluctuationExtreme power generation conditions4. communication failureIP address conflictAbnormal network cable connection5. Equipment quality defectsLow quality components/connectorsInsufficient installation heightSolution:1. Check the wiring and make corrections.  2. Inspect and replace damaged components.Check whether the DC joint is short circuited due to immersion or melting, and dry or replace the components.3. If the bus voltage is abnormal (overvoltage/undervoltage), check the battery stack voltage or protection parameter settings.  Voltage fluctuations in the morning and evening are normal phenomena and do not require any treatment. 4. Check if the touch screen and control board IP addresses are consistent and reset. Confirm if the network cable is loose or damaged, unplug and test again.  5. Poor quality materials can cause electrical leakage or open circuits, and qualified products need to be replaced.Adjust the installation height of the components to meet the standards.   It is recommended to prioritize troubleshooting wiring and insulation issues. If they cannot be resolved, please contact the manufacturer's technical support.‌‌‌Note: Please do not dismantle the machine without permission, otherwise it will be out of the warranty of Ktech.
