56 SI5048-TEN093630 Technical Description
– "New System" (if you would like to start a new system or perform changes to the system
configuration)
– "New Battery" (if you wish to reset battery-specific parameters only. You cannot change
general parameters using "New Battery")
– "Emerg Charge" (if you would like to charge a deeply discharged battery using an
external source)
3. Use "New System" to set the following parameters:
– Device type (master, slave 1, slave 2, slave 3)
–Voltage/frequency type (230V_50Hz, 220V_60Hz), default setting is "230V_50Hz"
– System configuration (see table for setting options), preset to "1Phase1".
– date / time
– Battery type (VRLA, FLA, NiCd), default setting is "VRLA"
– Nominal voltage of the battery (42 V - 52 V in 2-V steps for FLA and VRLA, 43.2 V to 48 V
in 1.2-V steps for NiCd), default setting: "48.0 V"
– Nominal battery capacity (100 Ah - 10000 Ah), default setting: "100 Ah"
Systems with one Sunny Island
If only one Sunny Island is used in the system, the device type is set to "master" and is not
displayed.
