ID57environment temperature1 protection

Name in the manufacturer's documentation (fault list): environment temperature1 protection[1]

In plain words (editorial)

Ambient temperature protection – the temperature around the inverter is too high. The manual says to check that the installation position and method meet the user manual, whether the ambient temperature exceeds the upper limit, and whether dust or foreign objects block the fan at the air inlet; it recommends cleaning the inverter once every half a year.

When to call a service technician: If it keeps happening after improving ventilation, contact your installer.
