Error: 300AC V Outrange

Name in the manufacturer's documentation (user manual): AC V Outrange[1]

In plain words (editorial)

The grid voltage is outside the permissible range. The manual says to switch off the DC switch, check the AC wiring (especially neutral and ground) and whether the grid voltage complies with the local standard, then restart.

When to call a service technician: If the problem still exists, contact Growatt through the installer.
