STATE 482Setup interrupted after initial start-up

Name in the manufacturer's documentation (service manual): Setup interrupted after initial start-up[1]

In plain words (editorial)

The setup was interrupted after the first start-up. The inverter is not feeding any energy into the grid. The manual says to restart Setup after an AC reset (switch the circuit breaker off and on again).

When to call a service technician: If Setup cannot be completed, contact the installer.
