BAT SETUP
Explanation
Low voltage off
Battery voltage at which energy is no longer drawn from
the battery
Low voltage on
Battery voltage at which energy resumes being drawn from
the battery
Voltage rel Nr.
Set the voltage level for switching connected relays at
inverter. In the „REL-Nr. mode“ menu, „VOLTAGE LEVEL“
must be activated in the inverter Setup menu. This will be
signaled by the set voltage value
Setting
24 V units:
17 - 32 V (factory setting 23 V)
48 V units:
34 - 64 V (factory setting 46 V)
Nominal temp bat
Manual setting of battery ambient temperature. Is only
applicable when no battery sensor is connected
Ubat correction
DC line correction factor for compensating for DC line
resistance as well as battery internal resistance. This is a
factory setting for the recommended line cross sections and
battery sizes.
(For more information about line cross sections, please see
the chapters on connecting the inverter)
When using
- a thicker line cross section, decrease the value accordingly
- a thinner line cross section, increase the value accordingly
SOC detection
Charge status detection in multi-device operation
LocalLocal detection: Charge status detection is carried out
locally at the respective device (separate battery supply per
inverter)
CentralCentral detection: Charge status detection via master
device (joint battery supply for all inverters)
> EXIT
Exit Setup menu using OK
Battery Menu
The Battery menu contains information about battery status and battery
settings.
