General Operation - Victron energy BMV 600 Manuel

3. GENERAL OPERATION

3.1 Monitoring menu
In normal operating mode the BMV can display the values of selected
important parameters of your DC system. Use the + and - selection keys to
select the desired parameter.
Label Description
V Battery voltage: this readout is useful to make a rough
estimation of the battery's state-of-charge. A 12 V battery is
considered empty when it cannot maintain a voltage of 10.5 V
under load conditions. Excessive voltage drops for a charged
battery when under heavy load can also indicate that the
battery capacity is insufficient.
Starter battery voltage: this readout is useful to make a
VS*
rough estimation of the starter battery's state-of-charge.
I Current: this represents the actual current flowing in to 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 5 A from the battery, it will be displayed
as –5.0 A.
CE Consumed Energy: this displays the amount of Ah consumed
from the battery. A fully charged battery sets this readout to
0.0 Ah (synchronized system). If a current of 12 A is drawn
from the battery for a period of 3hours, this readout will show –
36.0 Ah.
SOC 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 will
be indicated by a value of 100.0%. A fully discharged battery
will be indicated by a value of 0.0%.
Time-to-go: this is an estimation of how long the battery can
TTG
support the present load; until it needs recharging.
