6.0 DATA Menu
(Retrieving Performance Data)
A long-push on DATA, enters the data menu.
This displays performance information for the
current day.
The screens in the DATA menu have the
following meanings:
VMAX maximum battery voltage since midnight.
VMIN minimum battery voltage since midnight.
FTIM
time of day the regulator entered the
Float state.
SOC
estimated state of charge of the
battery based on the amp hours in and
the amp hours out. A very rough ‘fuel
gauge’ -see below for further details.
TEMP temperature being sensed by the
external temperature sensor (if attached).
SOLV solar panel voltage (open circuit)
HIST
entry point for history data.
changed from the ABSB (Absorption) state to the
FLOT (Float) state.
This time will only be recorded if the regulator
has done a transition into float that day. A time
will not be recorded if the controller did not
reach the float state or stayed in float all day. No
float time displays as a ‘-’.
6.4 SOC (State of Charge Display)
SOC (State Of Charge) should be read as a
percentage estimate of how full the battery is.
This estimate is based on the amp hour balance
counter. The counter keeps a running balance
of amp hours in vs amp hours out. The SOC
display shows this balance as a percentage of the
battery size. Note that all system currents must
be monitored by the regulator and the battery
capacity must be entered by the installer at the
BCAP setting before SOC will be meaningful.
Over time, a pure amp hour balance counter
will drift out of line with the real battery state of
charge. To keep the counter better aligned with
reality, the Dingo automatically makes a number
of corrections:
1. When the controller state changes from
boost to absorption, SOC is set to 90% if it
is <90%. When the controller state changes
from absorption to float, SOC is set to
100%.

At midnight, VMAX, VMIN, FTIM, SOC, IN and

from the current day readings.
6.1 & 6.2 VMAX and VMIN
VMAX and VMIN respond very slowly to changes
in battery voltage. This allows them to ignore
short term voltage fluctuations. A long push will
reset the value to the current battery voltage.
