dFac-Max Maximum "grid frequency change" before the grid monitoring

system disconnects the device from the grid.

dZac Maximum "grid impedance change" before the grid monitoring

system disconnects the device from the grid.

E_Total Total energy yield for the inverter. This change may be

necessary when you replace the Sunny Boy and want to use the

data stored in the old device.

Fac-delta- Maximum frequency, above (Fac-delta+) and below (Fac-delta-)

the grid frequency of 50 or 60 Hz, before the grid monitoring

system disconnects the device from the grid.

Fac-delta+

Fac-Pderating Frequency-dependent output limitation.

Fac-Tavg Averaging time of grid frequency measurement.

h_Total Total hours of operation for the inverter. The changes may be

necessary when you exchange your Sunny Boy and want to use

the data from the old device.

I-NiTest Setting the impulse for impedance monitoring. This parameter

only functions when the Sunny Boy is deactivated (disconnected

on the AC side) or in "Stopp" mode.

Speicherfunktion Default parameter: returns all parameters to the factory settings.

Reset Betriebsdaten: returns all user level parameters to the

factory settings.

Reset Fehler: resets a permanent error.

Speicher/Storage Permanent: modified parameters are stored in the EEPROM and

can be used even when the Sunny Boy has been restarted.

Volatil: prevents the parameters being stored in the EEPROM,

the parameters are only stored until the next restart.

T-Start The period the Sunny Boy waits after all switch-on conditions

have been satisfied.

T-Stop The period the Sunny Boy waits before disconnecting from the

grid.

Uac-Min Lower (Uac-Min) and upper (Uac-Max) limits of the allowable

AC voltage (stand-alone grid recognition), before the grid

monitoring system disconnects the device from the grid.

Uac-Max

Uac-Tavg Averaging time for measuring grid frequency
