Connecting External Sources
Information
The recording of autostarts is only reset after the generator has been successfully
connected and the minimum run time has expired or when the locked error state
(FailLock) is disabled.
Information
The error state and the locked error state can be cancelled by confirming the generator
fault ("540.02 GnAck" parameter).
The "133.03 GnRmgTm" process 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 power-down time (Cool)
• Remaining stop time after the power down-time has elapsed (Lock)
• Remaining time in the error state (Fail)
• Remaining time in the locked error state (FailLock)

NOTICE!
Damage to devices due to improper installation dimensioning.
When dimensioning your installation, please observe:
PAC
max., Sunny Boy
• The maximal AC output of the Sunny Boy inverter connected should not exceed
4.4 kW.
If the battery is fully charged, the frequency limits the power output of the AC feed-in generators
(Sunny Boys). 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 feed-in generators
(Sunny Boys) would then feed additional energy into the system and possibly overload the batteries.
