2.3.3 Derating
Output derating is a way to protect the inverter form overload or potential faults.
Situations require inverter power derating are:
Internal temperature is too high (including ambient temperature and module
temperature)
Grid voltage is too low
External power class adjustment
Grid frequency is too high
[*]
Note: [*] valid only when the country selected is DE or IT.
Power Limit Setting
Inverter output power can be adjusted via the LCD display or remote grid dispatch
from the grid company. The corresponding operating state will display on the LCD
screen.
