  • Page 121: 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 122: Charge Control

    SMA Solar Technology AG Battery management 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 123 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 12.4.1 "Boost Charge"...

  • Page 124: Boost Charge

    SMA Solar Technology AG Battery management Charging voltage change The charging voltage does not rapidly change, but is slowly adjusted to the new nominal value by approx. 0.5mV/cell*s as the constant voltage phase changes to the float charge. This also takes place if the nominal value is changed manually.
  • Page 125 SMA Solar Technology AG Battery management Information If the Sunny Island changes to full charge after a boost charge has been running for a specific time, this boost charge time is fully credited toward the full charge. Information If more than 1 % of the battery's nominal capacity is discharged during a full charge, 50 % of the time elapsed is credited towards the constant voltage phase.

  • Page 126: Equalization Charge

    SMA Solar Technology AG Battery management 12.4.3 Equalization Charge A battery bank consists of many individual battery cells connected in series which all behave slightly differently. Over time, this results in different charge levels in the individual cells. This can lead to premature failure, initially of individual cells, and finally to failure of the entire bank.

  • Page 127: Manual Equalization Charge

    SMA Solar Technology AG Battery management 12.4.4 Manual Equalization Charge The parameter "520.01 ManChrgSel" activates the manual equalization charge on the Sunny Island. If a generator is connected to the system, it will be automatically started, and stopped again after the equalization charge is completed.
  • Page 128 SMA Solar Technology AG Battery management Level 2: The second level of the battery preservation mode ensures that the Sunny Island is started regularly every two hours only in the time period during which energy supply is expected, and that it attempts to charge the battery from the AC side.

  • Page 129: Battery Diagnostics

    SMA Solar Technology AG Battery management The battery preservation mode can be quit by manually starting the Sunny Island. If a charging current is detected within 5 minutes (see above) the Sunny Island remains in operation; otherwise, it is disconnected again.

  • Page 130: Connecting External Sources

    SMA Solar Technology AG Connecting External Sources 13 Connecting External Sources The Sunny Island supports the integration of external energy sources. A distinction is made between the integration of a generator and the integration of the public grid. Both the generator ans the public grid are integrated via the Sunny Island's AC2 connection. A single-phase or a three-phase connection is possible.

  • Page 131: Connecting Generator Connections In Parallel

    SMA Solar Technology AG Connecting External Sources 13.1.1 Connecting Generator Connections in Parallel In the case of Sunny Islands connected in parallel and which operate on the same phase, 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 132 SMA Solar Technology AG Connecting External Sources The following illustration shows the wiring for a generator that cannot be started remotely: Sunny Island Relay1 PE N L PE N L Island Grid Generator The generator must always be switched off manually too. The Sunny Island automatically switches to operation without generator.

  • Page 147: Conditions

    SMA Solar Technology AG Connecting External Sources 13.2.1 Conditions In order to operate on the grid, very strict limits (for voltage and frequency) must generally be maintained. This 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 148: Grid Operation

    SMA Solar Technology AG Connecting External Sources 13.2.4 Grid Operation In grid operation, the stand-alone grid and main power grid are connected. The Sunny Island is connected along with the stand-alone grid to the main power grid. Therefore, the voltage and frequency in both grids are identical.

    SMA Solar Technology AG Connecting External Sources 13.2.5 Grid Failure A grid fault is characterized by the voltage or frequency being outside of the permissible limits (see section 13.2.3 "Grid Reconnection" (Page 147)) or the main power grid being disconnected. In this case, the time limits are relevant: Smaller deviations are permitted for longer than large deviations (see section 13.2.1 "Conditions"...

  • Page 150: Operation Together With Sunny Boys

    SMA Solar Technology AG Connecting External Sources 13.2.8 Operation Together With Sunny Boys Since electricity is fed into the grid through the relay of the Sunny Island, it must be prevented from overloading. For this reason, reverse power monitoring is used which, if required, disconnects the main power grid if the reverse power limit is exceeded or an excessive load is applied to the relay.

  • Page 151: Generator And Grid

    SMA Solar Technology AG Connecting External Sources 13.3 Generator and Grid In addition to the public grid, a generator can also be integrated into an island grid system as a secondary protective measure. This is particularly useful in case of long-term grid failures, if after some time the battery size no longer suffices either, to bridge the failure.

    In the Sunny Boy / Sunny Mini Central, this function is performed by the "SMA grid guard Version 2". In the case of the Sunny Backup 2200 and Sunny Backup 5000 it is integrated in the Automatic Switch Box.
  • Page 203 SMA Solar Technology AG Glossary Automatic Switch Box Switching unit which switches the Sunny Backup System between grid and off-grid operation. In grid operation, a PV plant in the Sunny Backup System is operated via an automatic disconnection device at its own feed-in counter. If the grid drops out it is switched to the stand-alone grid separated from the public grid.
  • Page 204 SMA Solar Technology AG Glossary Boost Charge Quick charge: allows the battery to be charged to a level of approx. 85 – 90 % as quickly and efficiently as possible. Bulk Phase I-Phase: the charging phase in which charging can be performed using the maximum charging current.
  • Page 205 SMA Solar Technology AG Glossary Derating A controlled reduction in performance, usually dependent on component temperatures. Compared with the (also common) practice of completely shutting down the device, the effect on the external grid is smaller with derating. Abbreviation for Digital Signal Processor. A DSP is a microprocessor chip especially developed for digital signal processing and control.
  • Page 206 SMA Solar Technology AG Glossary Flash EEPROM The abbreviation EEPROM stands for Electrically Erasable Programmable Read-Only Memory. Flash memories are digital storage devices (chips). The exact designation is "flash EEPROM". In contrast to "normal" EEPROM memories, in flash EEPROM it is not possible to delete individual bytes (the smallest addressable memory units).
  • Page 207 SMA Solar Technology AG Glossary Invert Mode See Inverter Operation. Inverter operation Operating mode of a battery inverter where it supplies the stand-alone grid from the battery energy. In this operating mode, the battery inverter is especially responsible for the control of frequency and voltage in the stand-alone grid.

Details on the Powerline modem can be found in the technical description of the SMA-NLM among other places. Nominal Charge Throughput The charging throughput is the cumulative total discharge current over time, measured in ampere hours (Ah).
  • Page 209 SMA Solar Technology AG Glossary Piggy-Back (Board) A printed circuit board which is plugged into another board to increase performance or expand capabilities. A piggy-back board can also replace an individual chip. In this case, the chip is removed and the board is plugged into the empty socket.
  • Page 210 SMA Solar Technology AG Glossary State of Charge: the charge level of the battery, see Charge Level. If, for example, 25 Ah is taken from a 100-Ah battery, the charge level (SOC) is then 75 %. State of health: describes the relationship between the present capacity and the battery's nominal value, given as a percentage.
