    If a ground connection is necessary, establish it separately outside of the Sunny Island. Calculating the Required Grounding Cable Cross-Section SMA Solar Technology cannot state generally valid values for the cross-section of the cable required for the external grounding of the battery. The cable dimensions depend on the type and size of the battery connected, the external fuse (DC side) and the material used in the grounding conductor.

  • Page 31: Dc Connection

    SMA Solar Technology AG Electrical Connection The DC grounding conductors must be connected to the connection labeled "Ground". The grounding cable is installed in five steps: 1. Loosen the cable screw connection on the Sunny Island. 2. Thread the grounding conductor through the cable screw connection.

  • Page 93: Start Options

    SMA Solar Technology AG Battery management NOTICE! Possible damage to the battery as a result of faulty temperature measurement. If the battery temperature sensor is defective or missing, the Sunny Island continues to run, assuming a battery temperature of 40 °C. This can result in insufficient charging of the battery in the long run.

  • Page 94: Charge Control

    Battery management SMA Solar Technology AG The battery's state of health (display value "320.01 Soh") is a measurement of the present useable capacity expressed as a percentage relative to the nominal capacity. 100 % means that the entire nominal capacity can be used. 50 % means that only half of the original nominal battery capacity can be used.
  • Page 95 SMA Solar Technology AG Battery management In this phase, the battery voltage is maintained at a constant level, resulting in a continually decreasing battery current. The Sunny Island remains in this phase for a defined period of time ("222.02 — 222.03", AptTmBoost or AptTmFul or AptTmEqu" parameters). For this charging phase, the Sunny Island automatically selects one of three possible charging methods (boost, full, equalizing) which are described in detail in sections 13.4.1 ”Boost Charge”...

  • Page 96: Boost Charge

    Battery management SMA Solar Technology AG The charging capability of batteries is highly dependent on the battery temperature. For temperatures < 20 °C, the charging voltage must be slightly increased, and for temperatures > 20 °C it must be slightly decreased. This is necessary to prevent overcharging and insufficient charging reliably at any battery temperature.

  • Page 97: Equalization Charge

    SMA Solar Technology AG Battery management External charging device If an external charger or charge controller is connected to the battery and the criteria for a full charge are fulfilled due to external charging, the Sunny Island treats this as if it had performed the full charge itself.

  • Page 98: Manual Equalization Charge

    Battery management SMA Solar Technology AG 13.4.4 Manual Equalization Charge The parameter "520.01 ChrgSelMan" activates the manual equalization charge on the Sunny Island. If a generator is connected to the system, it is automatically started and stopped once the equalization charge is completed.

  • Page 99: Battery Preservation Mode

    SMA Solar Technology AG Battery management 13.5 Battery Preservation Mode The Sunny Island has a sophisticated battery preservation mode. The battery preservation mode prevents deep discharge from the battery as far as possible when the energy supply is low, thus preventing a total system failure as well as damage to the battery.

  • Page 102: Connecting External Sources

    Connecting External Sources SMA Solar Technology AG 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 public grid. Both the generator as well as the public grid are integrated through the AC2 connection of the Sunny Island.

  • Page 103: Connection In Parallel

    SMA Solar Technology AG Connecting External Sources 14.1.1 Connection 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 104 Connecting External Sources SMA Solar Technology AG 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, among other things. In this case, the Sunny Island does not have the option of starting the generator. It only monitors the generator input (AC2).
  • Page 105 SMA Solar Technology AG Connecting External Sources 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.

    SMA Solar Technology AG Connecting External Sources 14.1.5 Automatic Generator Operation In automatic operating mode ("235.01 GnAutoEna" parameter), the Sunny Island automatically defines the settings (as a function of battery charge state or loads) to determine 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 14.1.9 Stopping the Generator If the generator was started via the Sunny Island (automatically or manually), it can be manually stopped at any time using the "540.01 GnManStr" parameter. This disconnects the generator (the minimum run time is not taken into account here) and the power down time (Cool) is skipped.

    Connecting External Sources SMA Solar Technology AG 14.2.1 Boundary Conditions In order to operate on the grid, very strict limits (for voltage and frequency) must generally be maintained.
