Error code
Description
Suggestion
Error: 101
Communication fault Slave
processor can't receive data
from Master processor.
1.Restart inverter
2.If error message still exists,
contact Growatt.
Error: 102
Consistent fault. Data
received by Master and Slave
processor are different. The
reason can be utility grid
voltage or frequency change
frequently. .
1.Restart inverter.
2.If error message appears
frequently or error message
still exists after replacement,
check utility grid. If you require
help, contact Growatt.
3.If error message still exists,
