GoodWe error code: DC overvoltage
DC overvoltage usually occurs when the total open-circuit voltage of PV strings exceeds the inverter’s maximum DC input limit. It can also happen if HV battery modules are installed in series beyond allowed limits.
This may cause the inverter to stop operating or trigger protection circuits to prevent damage.
Contact e-Solar to check DC voltage and battery configuration
If your inverter shows DC overvoltage, do not disconnect panels or batteries yourself. e-Solar can check PV string voltages, battery module configurations, and ensure that the inverter is operating within safe DC limits.
Contact e-Solar and let us know:
- The exact error code on the screen or app
- When the code appears
- Whether your solar production has dropped
