Installation Guide

Operating mode

Operating mode of the Sunny Boy:
MPP: Maximum Power Point
UKonst: Constant voltage mode (desired voltage is defined in
"Usoll-Konst")
IKonst: Operating mode for test purposes
Stopp: Disconnection from mains network, no operation
Turbine Mode: Operating mode for wind energy systems.
Off Grid: Operating mode for Sunny Boys in a stand-alone grid.

Plimit

Upper limit for AC output power

SMA-SN

Serial number of the Sunny Boy

Software-BFR

Firmware version of the operation control unit (BFR)

Software-SRR

Firmware version of the current control unit (SRR)

Storage function

Default parameter: Returns all parameter values to the factory
setting.
Reset Betriebsdaten: Returns all user level parameter values to
the factory setting.
Reset Fehler: Resets a permanent fault.

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 from being stored in the
EEPROM, the parameters are only stored until the next restart.

T-Start

The period the Sunny Boy waits after the Upv-Start value has
been reached.

T-Stop

The period the Sunny Boy waits before disconnecting from the
mains supply when Pac drops below the set value.

Uac-Min
Uac-Max

Lower (Uac-Min) and upper (Uac-Max) limits of the allowable
AC voltage (self contained power system recognition), before
the grid monitoring system disconnects the device from the grid.

Uac-Tavg

Averaging time of grid frequency gaging

Upv-Start

The DC voltage required before the Sunny Boy begins feeding
power into the mains supply.

Usoll-Konst

PV desired voltage for constant operational voltage. These
parameters are only important when the "Operating mode"
parameter is set to U-konst.
