Run Times - SMA Sunny Island 2012 Technical Description

SMA Solar Technology AG

13.1.7 Run Times

If the generator is started (or the Sunny Island detects an external generator start), the warm-up
phase starts. If, during this time, the voltage or frequency detected is not within the permissible
range, the warm-up phase begins again.
If the generator cannot be connected at the GenMan within twice the time set at "233.12
GnWarmTm" + 2 or 10 minutes, the connection process is cancelled and a new attempt is made.
After three attempts, the system changes to error state (Fail).
If the generator has been connected, the minimum run time begins ("233.08 GnOpTmMin"
parameter). The generator remains connected during this time, even if in the meantime the generator
request is no longer present.
If the minimum run time has ended and a generator request is no longer present, the generator
disconnects and enters the power down phase (Cool). If this power down phase is completed after
the time specified in "233.10 GnCoolTm", the generator is stopped.
Information
The power-down time ("233.10 GnCoolTm" parameter) defined on the Sunny Island
should be set equal to or preferably greater than the power-down time of the GenMan.
If a generator fault (e.g. generator failure) is detected, the generator is also disconnected and then
stopped immediately. In doing so, the power-down time is skipped.
Once the stop time (233.09 GnStpTmMin" parameter) has elapsed, the generator is ready for the
next request.
Information
An internal generator request is disabled during the power down time and stop time or
in error state.
If a generator fault is detected several times and the number of autostarts ("234.02 GnAutoStr"
parameter) has been exceeded, the system transitions into the locked error state.
This state lasts for the time period set at "233.11 GnErrStpTm". Once this time has elapsed, the
generator is ready for another attempt.
