Troubleshooting Suggestion
1. Check if the DC line is reversed.
2. Restart the inverter.
3. If it is still not excluded, please contact
the factory customer service.
1. Check whether the AC connection is
virtual.
2. Restart the inverter.
3. If it has not been eliminated, contact the

1. Connect each string component
individually to determine if it is caused
by a component problem. If there is no
error when inserting one of the string
components, it can be determined that it
is a string problem. Check whether the
string in question is broken or not.
2. If this error is only caused by a rainy day
or a certain time of the morning, it is
because the aging of the module causes
the leakage current to be too large.
When the weather is fine or the air
humidity is reduced, the error will be
cleared automatically. Can be resolved
through remote upgrade software.
