General Operation - Studer SBM-01 Bedienungsanleitung

3. GENERAL OPERATION

In normal operating mode the SBM-01 can display the six most important
parameters of your DC system. Use the < and > selection keys to select
the desired parameter.
Battery voltage (V). This readout is useful to make a raw
estimation of the battery's state-of-charge. A 12V battery is
considered empty when it cannot maintain a voltage of 10.5V
under load conditions.
Current (A) represents the actual current flowing in or out of
the battery. A discharge current is indicated as a negative
value (current flowing out of the battery). If for example a DC
to AC inverter draws 5Amps from the battery, it will be
displayed as –5.0A.
Consumed Amphours (Ah) displays the amount of Amphours
consumed from the battery. A fully charged battery sets this
readout to 0.0Ah (synchronized system). When for three
hours a current of 12Amps is drawn from the battery, this
readout gives –36.0Ah.
State-of-charge (%). This is the best way to monitor the actual
state of the battery. This readout represents the current
amount of energy left in the battery. A fully charged battery
sets this readout to 100.0% while a fully discharged battery is
represented as 0.0%.
Time-to-go (h:m) is an estimation of how long the battery can
support the present load, before it needs recharging. This
time will be represented in hours (above 100h) or in hh:mm
format (under 100h). A time-to-go of 15 hours and 45 minutes
will be represented as 15:45 h:m and a time-to-go of 120
hours will be represented by 120 h. When the battery is being
charged the display will show ---- h, which means that no
time-to-go can be calculated.
