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 manner 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. Using the
"510.03 InvTmOpStrDt" parameter, you can specify the starting date, and using 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, every day or weekly, at or from 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).
