Alarm 2067Faulty power collector

Name in the manufacturer's documentation (fault list): Faulty power collector[1]

In plain words (editorial)

The inverter has lost communication with the power meter, or the meter's CT or PT is disconnected. The manual says to check the meter model and RS485 settings, its power supply and the RS485 cable.

When to call a service technician: Have your installer check the meter and its wiring.
