Introduction
Please read the User Guide before reading this
manual.
In most cases, the User Guide provides all the
information needed for effective installation of
the Dingo, and there is no need for the user to
read this Reference Manual.
Some users will require further information. This
manual provides a detailed technical description
of the operation of the controller. This manual
assumes more technical knowledge than the User
Guide.
If you are in any doubt, it is recommended you do not
adjust the advanced settings described in this manual.
Incorrect adjustment may reduce the effectiveness of
your Dingo and could damage your battery.
All voltage values used in this manual assume
a 12V system. Scale voltages for other system
voltages (e.g. 24V system = voltages x 2, 48V
system = voltages x 4)
Additional Installation Notes
Ensure that you have followed the installation
instructions on pages 3-5 of the User Guide. The
Dingo can be used for system voltages up to 48V.
It is safe to connect the power before setting the
system voltage, even with a 48 volt battery.
Always mount the Dingo vertically with clear
airflow around the bottom and top of the case.
In hot conditions, do not put it in a sealed
enclosure, as this will restrict the airflow around
it. Do not install the Dingo in direct sunlight in
hot conditions.
Please consult section A.4 to determine the
performance that can be expected in hot
conditions.
The Dingo is specified for up to 60°C ambient
temperature. At full power, in high temperature
ambients, the LCD display may occasionally reach
a high enough temperature to become darker and
may become unreadable. It will return to normal
when it cools down.

Features
The Dingo series of solar controllers is
exceptionally versatile. They give the user
unparalleled capability to adjust the function of the
controller and to monitor the performance of the
energy system.
To cater for non technical users, the Dingo has
four preset programs which can be used without
needing to understand the details of its operation.
For those with a good understanding of solar
regulation, there is another program, which allows
all the settings to be adjusted if required.
Once the program has been selected, it is
possible to disable any further adjustment. This
prevents unauthorised adjustment of settings.
Although the Dingo is primarily a device to control the
charging of batteries from solar electric (photovoltaic)
panels, it can also be used with other energy sources
such as wind, microhydro and fuel driven generators.
The Dingo supports a variety of regulation
methods. It supports slow speed switching and
fixed frequency pulse width modulation (PWM)
control in series and shunt modes.
Low battery voltage load disconnection is
provided, as are an alarm, facility to control the
charging of a second battery bank and control for
a back up generator. The event controller can
be used to control lights, pumping, waste energy
use and other timer functions.
A temperature sensor can be added to correct
the regulation voltages for battery temperature.
There is an input for measuring external voltages.
A serial interface is provided for accessories
including extra switch blocks, remote current
sensors and communication with a computer/
modem.
Using an external current shunt attached to
a remote current sensor (DSA) allows the
controller to see other current flows in the
system.
The Dingo can control larger systems by adding
external switch blocks attached to the serial bus.
The DUSB or D232 interfaces allows remote
monitoring and adjustment. Custom settings
can be stored on a computer and uploaded into
the controller. Data from the controller can be
downloaded into the computer and displayed
easily.
Overload Protection
The Dingo has overcurrent protection on both
the load and charge switches.
If the user accidently short circuits the load or
the charge connections, then the switch will turn
off very quickly before any damage is done to the
switch.
If the user overloads the load switch, then the
load switch will disconnect after a period of
time to protect itself from overheating. It will
reconnect automatically once the switch cools
If the charge input is overloaded, then the
controller will turn the charge switch off, as
required, to reduce the average charge current
into the Dingo.
For details see section A.4.
Thermal Protection
The Dingo has a temperature sensor on the
circuit board. The function of this sensor is to
tell the Dingo how hot it’s own circuit board
is so that it can reduce the charge current (the
major heating source) in order to protect against
overheating.
See section A.4 for details of thermal derating
Menus
The Dingo has a simple main menu. This is
described in the user guide and provides most
the information required for normal use.
Behind each of the main menu screens are sub
menus. These are entered by doing a long push
in the main menu. They allow access to more
information and control of more advanced
features.
The following pages describe each submenu in
detail.

1.0 BATV Menu
The BATV screen, shown at power-up, displays
the real-time battery voltage.
A long push on the BATV screen will display the
state of the charge regulation cycle.
The Battery Charge Cycle
The Dingo’s sophisticated regulation system
is designed to keep the battery fully charged
without overcharging it.
To achieve this, it uses a charge control process
with three main states. These states are Boost,
Absorption and Float. It also uses a fourth state
from time to time, called the Equalisation state
(See fig 1B.)
1.1 BOST (Boost)
In the boost state, all the charge current available
is used to charge the battery. As the battery
charges, its voltage rises. When the voltage
reaches the boost maximum voltage (BMAX) and
remains there for 3 minutes, the controller will
automatically advance to the absorption state and
then, later, to the float state.
Returning to Boost state
To get this charge cycle to repeat, the Dingo
must return to the boost state. There are three
ways that it can do this.
a. Low Battery Voltage
If the battery voltage falls below the boost return
voltage BRTN for more than 10 minutes, then
the Dingo will switch back into the boost state.
The delay is necessary to prevent large short
term loads causing unnecessary returns to Boost.
b. Programmed boost cycles (optional)
The Dingo will automatically do a boost cycle
after a set number of days (BFRQ), regardless of
battery voltage.
c. Manual boost
The user can manually set the Dingo into the
boost state (or any of the regulation states).
To manually advance to the next state, do a
long push on BATV. This will show the current
regulator state. (BOST=Boost, EQUL=Equalise,
ABSB=Absorption, or FLOT=Float). A longpush on that state will manually advance into
the next state. Or, to return to the BATV screen
without changing the state, do a short push.

Note: if ETIM is 0, then the Equalise state will be
bypassed. If ATIM is 0, then the Absorption state
will be bypassed.
On the BOST and FLOT displays, the battery
voltage is shown. On the EQUL and ABSB
displays, the time on the equalisation or
absorption timer is displayed. When this time
reaches the set time (ETIM or ATIM) the Dingo
will advance to the next state. Remember that
the timers will stop if the voltage falls too far
below the set point.
1.2 Equalise (optional)
Many battery manufacturers recommend that the
battery bank be given an overcharge occasionally.
This is a deliberate overcharge, designed to
equalise the voltages and specific gravities of all
the cells in the bank by bringing them all up to full
charge and to stir up the electrolyte in liquid cells
to reduce stratification.
The Dingo supports an automatic programmed
equalisation. This state allows the battery voltage
to rise until it gets to the equalisation voltage
(EMAX) and then remain at this voltage for the
set equalisation time (ETIM). This equalisation is
done every EFRQ days. (Typically 30-60 days).
Equalisation will begin at 9am on the appropriate
day. If ETIM is 0, then equalisation will not occur.
To prevent the controller being trapped in equalise
mode for a long time because there is inadequate
charge current to reach the equalise voltage, the
Dingo terminates equalise after 4 days
1.3 ABSB (Absorption)
In this state, the Dingo tries to keep the battery
voltage constant while the last part of the battery
charging occurs. This prevents excessive gassing
which occurs at high cell voltages. The Dingo
will keep the battery voltage at the absorption
voltage ABSV until it has been at this voltage for
the absorption time ATIM. When the absorption
time is finished, the Dingo advances to the Float
state.
If there is a cloudy period and there is insufficient
charge current to keep the voltage up to ABSV,
then the absorption timer will stop and resume
when the voltage comes back up to ABSV.
To allow some margin, the timer actually runs if
the voltage is above ABSV-HYST. (HYST is the
hysteresis setting used for slow speed switching
-usually about 0.4V)
1.4 FLOT (Float)
In this state, the battery has been fully charged.
The charge current is now used to keep the
battery voltage at a level which maintains full
charge. This voltage (FLTV) should be below the
gassing voltage to avoid excessive electrolyte
loss. If charge is drawn from the battery, the
Dingo will allow charging to resume until the
battery returns to FLTV.

2.0 CHRG Menu
CHRG
The CHRG screen gives the real-time total
charging current (Amps). This total is the sum
of solar charge current (CINT) and any external
charge current. This may be current from an
external switchblock or MPPT device connected
to the bus or an external current measured using
a current shunt and a DSA.
CINT
From the charge screen, a long push displays
CINT (Charge Internal). This is the real-time
solar charge current flowing into the SOL+
terminal. (measured in amps.)
External Charge
From the CINT screen, a short push displays
the current reading from any external device
attached which can measure current. If the
device is a maximum power point tracker
(MPPT) then this device is shown as MPTx,
where x is the device number. Similarly, for
switchblocks the display is SWHx and for shunt
adaptors, SHNx. The device number can be
from 1 to 4 for shunt adaptors and from 1 to
12 for MPPT or Switchblocks. To fit the display,
numbers greater than 10 are given letters. So 10
is A, 11 is b and 12 is C.
This list also allows the user to check that the
Dingo has found or ‘discovered’ all the external
devices attached to the bus. This discovery
process is automatic. If a device is not on the
list and should be, then refer to section 8.4 for
troubleshooting advice.
Generator Control
The Dingo has a comprehensive generator
controller built in. It works in a similar way to the
Low Battery Disconnect function. It is designed
to give a run or stop signal to an electronic
start generator. It does not handle the actual
generator start-up sequence - this should be
done by the generator itself.

GSET
In the GSET screen, a long push will manually
change the state of the generator output. The
GEN indicator at the bottom of the screen is
visible when the generator function wants the
generator to be running. Note: the Generator
will not turn on during the ‘quiet time’, if
selected. (see below)
GMOD
The generator can operate in four different
modes. The generator mode is selected in the
GMOD screen and can be 0-6.
Quiet time: In modes 0,1 & 2, the generator is
not allowed to operate from 9pm until 9am so as
to enforce a ‘quiet time’.
Modes 4-6 are the same as modes 0-2 except
that there is no quiet time.
Note - do not confuse the GSET described in Figure
2A with the screen of the same name described in
Section 7.5.2. which sets the G terminal function.
GEXD (Generator Exercise)

is good practice to exercise the generator
periodically. The Dingo supports this with an

automatic generator exercise function, which will
turn on every GEXD days. The number of days
since the last exercise is shown on the GDAY
screen. The generator will run for GRUN hours.
When exercising, the elapsed time is shown as
GTIM. Both GDAY and GTIM can be adjusted.
Note:
1. There is no generator exercise when GMOD = 3
(manual start).
2. GSET toggle does not work during generator
exercise
3. A small amount of overcharge will occur if
battery is already fully charged. Use a low GRUN
value if this is of concern.
GDEL (Generator changeover delay)
A programmable delay (in minutes) is used to
prevent false turn on or off of the generator due
to large transient loads. Default setting is 10 min.
The generic programs (PROG=0-3) use
voltage driven generator control (GMOD=0).
See “settings used in Programs 0-3” for on-off
voltages etc.
Generator Example
For example, if SOC% triggered generator on,
voltage-triggered generator off, and no quiet
time, is desired, set up the regulator as follows:
PROG = 4 Allows user adjustment.
GMOD = 5 SOC % ON, Voltage OFF,
no quiet time
CHRG menu : Set GON, GOFF, GDEL,
GEXD, GRUN as required
SET/REG : Check these settings are
correct for your battery type
Mode menu :
GSET = 2
or
LSET = 2
GSET if using ‘G‘ terminal for
generator control
LSET if using LOAD terminal
for generator control
Note: when changing from prog 0-3 to program 4,
the user can load the default settings for program 1
into the Dingo using the DFLT screen in the MODE
menu. See section 7.5.8. This can save a lot of time.
Generator Control
For many generators it is possible to control their
operation remotely. This is either a remote start or
run function built into the generator or a separate
remote start unit.
There is usually a pair of contacts that will cause
the generator to run if they are closed. This can be
done with a switch or a relay.
The Dingo provides a G relay which can be used
for this purpose. This relay is voltage free and solid
state. It can carry a current of up to 300mA and
can block 85V.
For some generators it is possible to connect the
G relay directly to the remote start input on the
generator. The wiring for this is shown in fig 2B.

This direct connection will work if the current
flowing through the remote start terminals is less
than 300mA. If the current is greater than this,
then it will be necessary to use an intermediate
relay with a higher contact current rating. The G
relay switches the intermediate relay which in turn
switches the remote start terminal. The wiring for
this is shown in fig 2C.
Chose a relay with a contact current rating suitable
for the remote start unit and a coil voltage which
is the same as the system voltage. The relay
coil should not draw more than 300mA when it
is energised. Be careful with automotive relays
because they can often be poor relays requiring
large coil currents. Use relays from the electronics
industry which generally have lower drive power.
The G relay terminals do not need a catch diode
across the relay coil to protect from the flyback
voltage. This protection is built into the G terminal.
It can be difficult to determine what current is
required to operate the remote start. The best way
to do this is to measure it. Short the remote start
terminals with a multimeter on its current range
and measure the current.
The manufacturer’s manual should contain this
information but often does not.
The generator control provided by the Dingo is
simple -a contact closure is provided when the
generator should run and the contacts open when
the generator should be stopped. It does not handle
the issues associated with starting such as fuel and
what to do if the generator does not start. This
should be handled by the remote start unit.

3.0 LOAD Menu
Low Battery Disconnect
(LSET, LOFF, LON, LDEL)
To prevent battery damage due to overdischarge, the Dingo has a function which turns
off the load if the battery voltage falls too low.
If correctly configured, equipment connected to
the Load+ terminal (the “load”) will be turned
off when the battery voltage falls below the
LOFF voltage for LDEL minutes. Once turned
off, the load will not be reconnected until the
voltage rises above the L ON voltage for LDEL
minutes. The L ON voltage should be set high
enough so that some recharge will have taken
place before reconnection, otherwise the
disconnection process can oscillate.
This feature is optional, and can be disabled
either by connecting the user load directly to
the battery, or by setting LOFF low enough so
that the low battery disconnect function never
activates.
The LOAD indicator at the bottom of the screen
is visible when the low battery disconnect
function wants to disconnect the load. (Note
that other settings can override the function, so
the LOAD indicator does not necessarily mean
that power has actually been disconnected
from the load.) When the disconnect timer has
begun to timeout, the alarm led will flash at a 2
second rate with the led mostly on. If the load
disconnect function operates, then the alarm led
continues flashing but with the led mostly off.
The Low Battery Disconnect function can also
be toggled manually by a long push when in LSET
menu (see Figure 3A).

The IN and OUT Ah counters are reset each day
at midnight.

Selecting a load switch
The low battery disconnect is an internal logical
function. To do something other than act as
a warning, it has to be used to control a load
switch.
This can be done in three different ways. It can
control the Dingo’s LOAD terminal, or the G
(General Purpose Output) relay or an external
switchblock attached to the bus. The sense of its
operation can also be reversed, i.e. it can turn on
the terminal when the function decides the load
should be disconnected. This can then be used as
a low battery alarm or to drive a relay to turn off
other loads.
The connection to real switches is set up in the
MODE menu. See section 7.5 for details.
DO NOT CONNECT AN INVERTER OR
ANOTHER BATTERY TO THE LOAD
TERMINAL. This terminal is rated at 20A.
Most inverters draw larger currents than
this and have their own low battery cut
off circuitry anyway. In general, Inverters
should be connected directly to the battery.

IN
The IN screen gives a running total of Amp
hours (Ah), or energy, that has been put into the
battery during the day (since midnight). This total
is the sum of Solar Ah collected directly through
the Dingo and any measured external Ah input.
IN/INT
From the IN screen, a long push displays INT
(Internal Ah IN). This is the running total of Ah
collected through the SOL terminal over the day
(since midnight). A long push will clear the INT
running total.
IN/External
From the INT screen, a short push displays any
external Ah contributions. This is the running
total of each external Ah input from MPPT,
Switchblock or current shunt measurements. A
long push will clear a total.
