120 SI5048-TB-TEN110340 Technical Description
The "133.03 GnRmgTm" display value is used to display the remaining time of the generator meter.
Depending on the current request or the phase in which the generator state machine is, the following
times are displayed:
• Remaining time of Run1h
• Remaining run time during the warm-up phase (Warm)
• Remaining minimum run time in operation (Run)
• Remaining run time during the follow-up time (Cool)
• Remaining stop time after the follow-up time has expired (Lock)
• Remaining time in the error state (Fail)
• Remaining time in the locked error state (FailLock)
14.1.8 Operation Together with PV Inverters
If the battery is fully charged, the frequency limits the power output of the AC feed-in generators
(Sunny Boy). If the generator is now manually started, for example, the frequency would be lowered,
if required, as the Sunny Island synchronizes with the generator. The AC feeding-in generators
(Sunny Boys) would then feed additional energy into the system and possibly overload the batteries.
In order to prevent this, in this case the stand-alone grid frequency is temporarily increased, in line with
the synchronization, until the AC feed-in generators (Sunny Boy) are disconnected from the stand-
alone grid system as a result of the grid limits being exceeded.
NOTICE!
Incorrectly plant designs will result in excessive AC power of the PV inverter.
• The maximum AC output power of the PV inverters connected should not exceed
10 kW per Sunny Island.
• Observe the following:

of the PV inverter = 2 x P
