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 end 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"
12.2 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.
12.3 Time-Controlled Operation
The Sunny Island can be operated in a time-controlled fashion using a timer function (like a clock
timer), supplying power at a planned point in time.
To do this, this function must be activated by using the "510.02 InvTmOpEna" parameter. With the
"510.03 InvTmOpStrDt" parameter you can specify the starting date, and with the "510.04
InvTmStrTm" you specify the starting time. With the parameter "510.05 InvTmOpRnDur" you set the
running time and with the parameter "510.06 InvTmOpCyc" you determine whether this function will
be carried out once, or every day or week, at or for the first time at the specified start time
(date and time).
Sleep Mode
The "Sleep Mode" works exclusively in stand-alone grid operation! The values for
connection and disconnection of the Sunny Island are already set at the factory
(optimized in terms of efficiency).
