Error: 202PV Voltage High

Name in the manufacturer's documentation (user manual): PV Voltage High[1]

In plain words (editorial)

The DC input voltage from the PV strings exceeds the maximum tolerable value. The manual says to disconnect the DC switch immediately and check the voltage of each PV string.

When to call a service technician: Have an installer measure the string voltages; per the manual, if they are below 550 V, contact Growatt.
