What to do if Huawei SUN2000 M0 shows Grid Failure?
If you're experiencing a grid failure with your Huawei Inverter, it could be due to a power outage, a disconnected AC circuit, or a switched-off AC switch. To resolve this, first, check the AC voltage. Second, check the AC circuit to ensure it is properly connected and that the AC switch is turned on.
What does Output DC Component Overhigh mean on Huawei SUN2000 M0?
If your Huawei Inverter displays 'Output DC Component Overhigh,' it means the DC component of the SUN2000 output current exceeds the specified upper threshold. The inverter detects its external working conditions in real time and should automatically recover once the fault is rectified. However, if the alarm occurs frequently, contact your dealer or Huawei technical support for further assistance.
Why is my Huawei SUN2000 M0 showing Abnormal Grounding?
If your Huawei Inverter is reporting Abnormal Grounding, it could mean the N cable or ground cable isn't connected properly, or that the inverter output is not connected to an isolation transformer when a PV array is grounded. To resolve this: Power off the inverter, then: 1. Check the PE cable connection. 2. If connected to a TN power grid, check the N cable connection and voltage to ground. 3. Check for an isolation transformer. If present, disable Grounding inspection via the mobile app, SmartLogger, or NMS.
What to do if Huawei Inverter reports Faulty Power Collector?
If your Huawei Inverter shows a Faulty Power Collector error, the power meter communication has been interrupted. To fix this: 1. Verify the power meter settings match the actual model. 2. Ensure the power meter's communication parameters match the SUN2000 RS485 settings. 3. Confirm the power meter is powered on and the RS485 cable is correctly connected.
