  • Page 107: Connecting External Sources

    SMA Solar Technology AG Connecting External Sources 14 Connecting External Sources The Sunny Island supports the integration of external energy sources. Here, a distinction is made between the integration of a generator and the integration of the power distribution grid. Both the generator as well as the power distribution grid are integrated through the AC2 connection of the Sunny Island.

  • Page 108: Connecting In Parallel

    Connecting External Sources SMA Solar Technology AG 14.1.1 Connecting in Parallel In the case of Sunny Islands connected in parallel which operate on the same phase and in the same cluster, the internal transfer relay is activated simultaneously. It is thus possible to multiply the generator current and therefore to connect a larger generator or a higher grid current.
  • Page 109 SMA Solar Technology AG Connecting External Sources Manual (Manual Generator Start) This setting is for generators that do not have an electrical remote starting option and, for example, are started using cable winches or cranks, or similarly. In this case, the Sunny Island does not have the option of starting the generator. It only monitors the generator input (AC2).
  • Page 110 Connecting External Sources SMA Solar Technology AG Autostart This allows autostart generators to be directly integrated. They have a separate internal controller that controls the start procedure. The Sunny Island requests the generator via the GnReq signal. If the generator voltage and frequency are within the set limits (see section 14.1.6 ”Limits and Power Adjustment”...

  • Page 114: Automatic Generator Operation

    Connecting External Sources SMA Solar Technology AG 14.1.5 Automatic Generator Operation In automatic operating mode ("235.01 GnAutoEna" parameter), the Sunny Island automatically defines the settings (depending on battery state of charge or load) as to when the generator starts and how long it runs. The automatic operating mode is activated using GnAutoEna = On (default).

    Connecting External Sources SMA Solar Technology AG Slave Device Failure You can influence the behavior of the cluster upon failure of a slave device. For more information, see section 12.8 ”Reaction in Case of Failures” (page 96). 14.2 Grid The Sunny Island supports the operation of grid backup systems on the grid. Here, a distinction is made between two main states: either a power distribution grid and stand-alone grid system are connected or a power distribution grid and stand-alone grid system are disconnected.

  • Page 123: Voltage And Frequency Limits

    SMA Solar Technology AG Connecting External Sources 14.2.1 Voltage and Frequency Limits In order to operate on the grid, very strict limits (for voltage and frequency) must generally be maintained. These strict limits are not sensible for generator operation. The limits are therefore set separately for grid operation and the generator limits are not used.

  • Page 124: Grid Reconnection

    Connecting External Sources SMA Solar Technology AG 14.2.4 Grid Reconnection In stand-alone grid operation, the Sunny Island constantly checks whether the grid has been reconnected (see above).
