Troubleshooting Suggestion
1. Perform the upgrade again.
2. If the upgrade fails several times,
contact your dealer or Huawei
technical support.
1. Apply for a new certificate.
2. Load the new certificate.
Turn off the AC output switch and
then the DC input switch. After 5
minutes, turn on the AC output
switch and then the DC input switch.
If the fault persists, replace the
board, If the upgrade fails several
times, contact your dealer or Huawei
technical support.
1. Check that the power meter
settings are based on the actual
model.
2. Check that the communications
parameters for the power meter
are the same as the SUN2000
RS485 parameter settings.
3. Check that the power meter is
powered on, and the RS485 cable
is connected correctly.
1. Check whether the grid
connection voltage exceeds the
upper threshold. If yes, contact
the local power operator.
2. If you have confirmed that the
grid-tied voltage exceeds the
upper threshold and have
obtained the consent of the local
power operator, modify the
overvoltage protection threshold
through the mobile phone app,
SmartLogger, or NMS.
3. Check whether the peak power
grid voltage exceeds the upper
threshold.
