Time-Controlled Operation; Overload And Short Circuit Behavior; Device Failure And Autostart - SMA Sunny Island 2012 Technical Description

SMA Solar Technology AG

11.4 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).

11.5 Overload and Short Circuit Behavior

The Sunny Island can be operated under overload conditions temporarily. It can also supply short-
circuit currents.
In the case of overload, the Sunny Island can deliver
• An output of 2900 W for 30 minutes at 25 °C
• An output of 3800 W for 5 minutes at 25 °C
In the event of a short circuit, the Sunny Island provides a maximum current of 25 A.

11.6 Device Failure and Autostart

If a critical fault occurs, the Sunny Island automatically shuts down and displays the reason on the
display. If the autostart function is activated ("250.01 AutoStr" parameter) the Sunny Island can
confirm the failure automatically and restart on its own. If the failure persists the Sunny Island cannot
be started.
Information
If the autostart counter has counted down to 0, the Sunny Island waits for 10 minutes
before attempting to restart automatically.
Information
Messages can be displayed during operation at any time, they have priority over the
display of the "Home Screen".
