Sleep Mode; Search Mode - SMA Sunny Island 2012 Technical Description

Additional Functions
Define the time intervals t1 and t2:
• Starting time t1: with the parameter "242.05 Lod1Tm1Str", set the start time for t1 (and with it
the end of t2).
• Starting time t2: with the parameter "242.06 Lod1Tm2Str", set the start time for t2 (and with it
the ent of t1).
• If the time intervals t1 (Lod1Tm1Str) and t2 (Lod1Tm2Str) are consistent with one another, only
t1 will be activated.
Set the battery state of charge at which the time interval t1 or t2 will start/stop:
• The battery state of charge during the t1 interval, the recognition of which will lead to the load-
shedding function being started: Parameter "242.01 Lod1SocTm1Str"
• The battery state of charge during the t1 interval, the recognition of which will lead to the load-
shedding function being stopped: Parameter "242.02 Lod1SocTm1Stp"
• The battery state of charge during the t2 interval, the recognition of which will lead to the load-
shedding function being started: Parameter "242.03 Lod1SocTm2Str"
• The battery state of charge during the t2 interval, the recognition of which will lead to the load-
shedding function being stopped: Parameter "242.04 Lod1SocTm2Stp"

11.2 Sleep Mode

Using the "250.10 SleepEna" parameter set to "Enable" allows the sleep mode to be activated in
single-phase grids, which the master uses to switch off the slaves when the power value allows this.
Sleep Mode
• The "Sleep Mode" works exclusively in stand-alone grid operation!
• The values for the switching on and off of the Sunny Island are set at the factory and
are fixed (and optimized for the efficiency rating).

11.3 Search Mode

The search mode is an energy-saving mode. When the power of the loads is less than 10 W for an
definable period of time (Delta T), the Sunny Island switches to the search mode. In the search mode
there is still voltage present at the AC1 terminal clamps.
With the parameter "250.26 SearchModTm", you can set the time interval Delta T (0 to 600
seconds).
