Additional Functions SMA Solar Technology AG 12.7 Time-Controlled Standby You can set the Sunny Island to standby mode in a time-controlled way. Activate the time-controlled standby using the parameter "250.13 SlpAtNgt". Set the parameter to "Enable". After activation, set the start time and the stop time for standby. Carry out the setting using the "250.14 SlpStrTm" and "250.15 SlpStpTm" parameters. 12.8 Reaction in Case of Failures You can influence how the Sunny Island reacts to failures occurring in a three-phase system using the "250.30 RnMod" parameter. The parameter is set to "RunAlways" at the factory. This means that the Sunny Island master ignores all faults at the slave devices. If you set the parameter to "StopAlways", the system will be put in standby mode upon detection of a fault at the slave devices. Faults which can be removed via an autostart are not included. 96 SI5048-TB-TEN110340 Technical Description
SMA Solar Technology AG Battery Management 13 Battery Management The battery management of the Sunny Island supports the following three battery types ("221.01 BatTyp" parameter): • FLA • VRLA • NiCd The battery capacity ("221.02 BatCpyNom" parameter) is to be entered as the nominal capacity for a ten hour discharge (C10). If this is not available from the battery manufacturer's data sheet, it can be calculated from the data for different discharge times (120 h, 100 h, 20 h, 5 h, 1 h) in the following manner: C10 C120/1.28 C10 C10 C10 C100/1.25 C10 C5/0.88 C10 C20/1.09 C10 C1/0.61 The Sunny Island is designed and set by default (parameter "221.03 BatVtgNom") for a nominal battery voltage: • 48 V (24 cells at 2 V each) in the case of lead batteries (FLA and VRLA) • 45.6 V (38 cells at 1.2 V each) in the case of Nickel-Cadmium batteries Failure of individual battery cells If individual battery cells fail over several years of continuous operation, the nominal voltage can be set in the range from 42 V to 48 V (see 8.2 ”Starting the Quick Configuration Guide (QCG)” (page 57)). Up to three individual cells can be removed and the system can still be further operated. 13.1 Battery Temperature The Sunny Island continuously monitors the battery temperature using the battery temperature sensor provided. At 5 °C under the maximal temperature allowed (set using the parameter "221.04 BatTmpMax"), a warning is displayed. If the maximum value for the battery temperature is exceeded, the Sunny Island switches off. A warning is output if the value for lead-acid batteries falls below –10 °C for below –20 °C for NiCd batteries. The battery temperature is taken into consideration when the charging voltage is calculated (see section 13.4 ”Charge Control” (page 99)). Technical Description SI5048-TB-TEN110340 97
