2. DESCRIPTION
2.1 The Skylla-TG battery charger
The Skylla-TG battery charger is a fully automatic charger for 24V batteries and accepts
any mains supply that delivers 90-265 V AC, with frequencies ranging from 45 to 65 Hz.
The Skylla-TG also accepts DC supply, ranging from 90 up to 400 V DC.
It charges the battery according to the IUoUo characteristic, which is a 3-stage charging
characteristic. This characteristic is shown below in illustration 1.
While charging, the Skylla-TG charger continuously measures the battery voltage and
current and recalculates the charging voltage and current based on the measured values.
Type Boost vo

Assuming that the battery is discharged, the Skylla-TG charger commences charging in
the boost-charge mode. In this mode the battery is charged until the battery voltage
reaches the boost voltage. At this point the battery is charged to approximately 80% of its
maximum capacity. This is the end of the boost-charge mode and the Skylla-TG charger
then automatically switches to the equalize-charge mode.
During the equalize-charge mode the charging voltage still equals the boost voltage, but
the charge current slowly decreases. The duration of this mode is pre-selectable and may
be set to 4, 8 or 12 hours. The standard time of the equalize-mode is 4 hours. After this
time the Skylla-TG charger automatically switches back to the float-charge mode.
In the float-charge mode the charge voltage decreases to the float voltage and the charge
current continues to decrease. This mode lasts for 20 hours.
After the float-charge mode the charger returns to the equalize-charge mode for 30
minutes, this is to compensate for the normal leakage or self discharge of the battery.
Illustration 1.

8 Manual Skylla with universal input
The Skylla-TG charger can remain connected to the battery continuously, without gas
formation taking place, caused by overcharging. It is not necessary to disconnect the
battery from the charger during long time storage, for example during the winter storage
of a ship. The Skylla-TG charger will keep your battery in optimum condition under all
circumstances and will prolong the lifetime of your battery.
A parallel load connected to the battery can cause a voltage drop. The Skylla-TG charger
automatically switches into the boost-charge mode when the battery voltage drops
below the minimal voltage.
The Skylla-TG charger is equipped with a separate starter-battery connection to charge an
extra battery, like a starter-battery. You can use this battery for starting machines, like a
boat engine for this application.
The Skylla-TG charger has a stabilised output voltage. Therefore the Skylla-TG charger can
also be used as a DC power supply in applications where no battery is present.
2.2 The battery
The Skylla-TG charger can charge various batteries. The recommended battery capacity is
indicated in the table below:
Type Recommended capacity
24V / 30A 100 –
200 Ah
24V / 50A 200 –
400 Ah
24V / 100A-G
500 -
1000 Ah
The charge voltages of the Skylla-TG charger are factory-set. Most battery manufacturers
recommend these charging voltages for optimal charging of 24V or 48V lead-acid
batteries.
It is possible to charge different types of batteries, like traction batteries. To charge these
batteries the charging voltages of the charger have to be changed. Contact your Victron
Energy dealer or battery dealer for more details about the recommended charging
voltages.
Page 9
Manual Skylla with universal input 9
2.3 Protection
The battery charger is safe to use due to its robust design and its internal electronic
protection. This chapter describes the various internal electronic protective devices.
Maximum charge current protection
The battery charger provides a maximum charge current of 30A for the 30A charger,
50A for the 50A charger or 100A for the 100A charger.
This level is electronically limited and is factory set.
The maximum output current can also be limited by using an external potentiometerpanel, the Victron Energy COV panel.
Short circuit protection
The charger output is protected against short-circuits. The short-circuit current is
electronically limited at 30A, 50A or 100A, according to the model. In this condition
the output voltage approaches 0 Volt. The battery charger resumes normal operation
when the short circuit is removed.
The short circuit current can also be reduced by the Victron Energy COV panel.
Input protection
The charger mains-input is protected with a fuse.
The charger will not be damaged by using input voltage between 0 and 300 Vac.
The charger will not be damaged by using input frequency between 0 and 65 Hz.
Over voltage protection
The charger switches off automatically when the battery voltage becomes higher
than the over voltage value. The charger switches back on when the battery voltage
becomes less than the raise value. See the table below.
Model
Over voltage value
Raise v
alue
24V 35,5 Vdc
33,5 Vdc
The charger output is protected with a fuse.
Starter battery protection
The output current of the starter battery output is electronically limited at 4A. The
starter battery output is also protected against wrong connections by means of a 10A
fuse.
Page 10
10 Manual Skylla with universal input
Temperature protection
The internal temperature of the charger is measured continuously. However, due to
a high ambient temperature outside the cabinet, the temperature within the
battery charger can rise. When the external temperature of the battery charger
becomes higher than 40°C, the output current decreases and the Failure led flashes.
Before the internal temperature becomes too high due to extreme conditions the
charger switches off and the Failure LED illuminates continuously. The charger
resumes operation when the internal temperature is restored within limits.
Voltage sense protection
When the voltage sense facility is used the charger automatically decreases the
output voltage when the voltage loss over the battery cables is more than 2 Volt in
total.
Battery watchdog timer
The charger is equipped with a battery watchdog timer. This timer measures the
duration of the boost mode. The moment the boost mode lasts longer than 10
hours, the charger will switch to float mode. The charging voltage will then become
the float voltage. In this way it is prevented that a defective battery is needlessly
charged with a high charging voltage.
Page 11
Manual Skylla with universal input 11
3. DIRECTIONS FOR USE
3.1 Installation
Find a dry and well-ventilated area to mount the Skylla charger and battery. Keep the
distance between the charger and the battery less than 6 meters.
The charger may be wall or floor mounted. Mounting on a wall improves the air
circulation within the charger cabinet and will prolong the lifetime of the battery charger.
The holes for the mains cable, the battery connections, the remote connections and the
earth connection are located at the bottom of the battery charger housing, see
illustration 2.
Connecting earth
Connect the earth screw to a real earth-point. Connections to earth have to be according
to applicable safety standards.
On a ship: Connect the earth screw to the earth plate or to the hull of the ship.
On land: Connect the earth screw to the earth of the mains.
Mobile applications (a vehicle, a car or a caravan): Connect the earth screw to the
frame of the vehicle.
Connecting the battery
The connections between the Skylla charger and the battery are essential for a good
operation of the charger. Therefore the battery connections need tightening well. It is
important to use short and thick battery cables to minimise the voltage losses in the cable.
Cable resistance decreases accordingly as the cables become shorter and thicker.
Therefore it is not recommended to use cables longer than 6 meters. The table below
shows the recommended cable core thickness.
Type core diameter of cables until 1,5m core diameter of cables between 1,5m and 6m
24/30 6 mm2 10 mm2

3.2 Operation
Located on the front of the Skylla charger are an on/off switch and three rows of leds, as
shown in illustration 5.
The battery charger can be switched on and off with the on/off switch.
The “output voltage” leds indicate the output voltage value.
The “output current” leds indicate the output current value.
The other leds indicates the state of the charger.
The operation sequence:
Switching the charger on with the on/off switch results in the following:
The “on” led will flash for about 2 seconds. In these first 2 seconds the charger reads
all input signals and calculates the necessary output voltage. After 2 seconds the
charger will switch on and the “on” led illuminates.
According to the condition of the battery the charger will start in the boost-charge
mode or at float-charge mode. If the battery is not full the “boost” led illuminates and
the charger will start boost-charging the battery.
A dip switch can be used to set the charger so that it will always start charging in
the boost mode, irrespective of the condition of the battery.
When the battery voltage has reached the boost voltage the charger will change into
the equalize-charge mode and the “equalize” led illuminates. This mode will last for a
pre-selectable time of 4, 8 or 12 hours.

There is a dangerous voltage present on some of the metal parts
inside the battery charger.
Page 17
Manual Skylla with universal input 17
4.1 Permanent boost-charge
In some cases, for example when the battery is almost empty, it is recommended to
permanent boost-charge the battery for 10 hours. Do not permanently boost-charge
sealed lead-acid batteries. Contact your Victron Energy dealer or battery dealer for more
information on charging the battery.
To set the charger into the permanent boost-charge mode :
Place the DIP switch number 8 “R boost” to the left. In this mode
the battery is being charged to the boost voltage.
Do not permanent boost-charge the battery for longer than 10
hours as this can cause long term gas formation in the battery and
will damage the battery.
While a battery is being boost-charged, check the water level of
the battery frequently and if necessary add distilled water to the
battery.
4.2 Adjusting the charge voltage
The battery charger has a factory set float and boost voltage. The boost-voltage is always
higher than the float-voltage. These charging voltages are the recommended values
from almost every battery manufacturer. Before adjusting the charge voltage disconnect
the temperature sensor and/or the voltage sense wires.
To change the float-voltage:
Remove all batteries and other users that are connected to the
output of the battery charger.
Plug the AC plug into the mains and switch on the charger.
Place DIP-switches 7 “Eq2” and 6 “Eq1” to the left position, this will
reduce the equalize time to 0 hours. The charger switches into the
float-charge mode.
Place DIP-switch 4 “fine” to the left position in order to accurately
adjust the output voltage.
Measure the float-voltage on the charger output by using a precision
voltage meter.
Adjust the float-voltage by turning the “V float” potentiometer until
the recommended voltage is reached.
Correct the equalize time by moving DIP-switch 7 “Eq2” and 6 “Eq1”.
Place DIP-switch 4 “fine” to the right position. In this position the
output voltage is less sensitive to influence of temperature.
Page 18
18 Manual Skylla with universal input
To change the boost-voltage:
Place DIP-switch 7 “Eq2” to the right and place DIP-switch 8 “R boost”
to the left. The charger switches into the boost-charge mode.
Place DIP-switch 4 “fine” to the left position in order to accurately
adjust the output voltage.
Measure the boost-voltage on the charger output by using a
precision voltage meter.
Adjust the boost-voltage by turning the “V boost” potentiometer
until the recommended voltage is reached.
Replace DIP-switch 8 “R boost” to the right.
Correct the equalize time by moving DIP-switch 7 “Eq2” and 6 “Eq1”.
Place DIP-switch 4 “fine” to the right position. In this position the output
voltage is less sensitive to influence of temperature.
4.3 Adjusting the equalize-charging mode time
The duration of the equalize-charge mode can be changed to fit the specifications of
the battery. The duration of the equalize-charge mode can be set to 0, 4, 8 or 12 hours.
When selecting 0 hours, the charger will skip the equalize-charge mode and will directly
switch into the float-charge mode. The standard equalize-time is 4 hours.
According to the table below the duration of the equalize-charge mode can be set by
moving the DIP-switches 7 “Eq2” and 6 “Eq1” in the corresponding way:
4.4 Diode-splitter charge voltage compensation.
If a diode-splitter (Victron Energy Argo) is connected to the Skylla
charger the charge voltage have to be raised to compensate for the
voltage loss over the diode-splitter.
If the voltage-sense option is used, do not use the diode-splitter
compensation. When both options are used simultaneously the
output voltage will be too high.
To select the diode-splitter option:
Place DIP switch 5 “split” to the left.
0 hours 4 hours 8 hours 12 hours
Page 19
Manual Skylla with universal input 19
4.5 Traction battery compensation
If a Traction-battery is connected to the Skylla charger the charge
voltages have to be changed. The output voltage has to be raised to
correctly charge the traction-battery. It is possible that the charge
voltages are not correct after activating this compensation. See for
adjusting the charge voltages chapter 4.2.
To set the charger into the traction mode:
Place DIP-switch 3 “trac” to the left.
4.6 Use as a power-supply
The Skylla charger can be used as a power supply without the obligation to connect a
battery to the charger output.
To use the charger as a power supply:
Put the charger into the permanent boost-charge mode, see chapter 4.1.
Adjusted the output voltage to the desired voltage, see chapter 4.2.
With the above mentioned procedure the output voltage range is limited. When the full
output voltage range is required please contact your Victron Energy dealer. See chapter
6.3 for details.
4.7 Use of a temperature sensor.
The temperature sensor supplied with the charger can be
connected to the charger by using the 3 meter cable with
stripped and tinned cable ends. This sensor should be
mounted on the battery. The temperature sensor adjusts
the charging voltage according to the battery
temperature.
To connect the temperature sensor:
Disconnect the mains,
Connect the - (black wire) of the temperature sensor
to the “-tmp” connector, see illustration 8.
Connect the + (red wire) of the temperature sensor to
the “+ tmp” connector, see illustration 8.
Switch on the mains.
If the temperature sensor is correctly connected the
“TMP OK” on the printed circuit board led illuminates.
If this led does not illuminate or flashes, the sensor is
not connected correctly.
Illustration 8.
Location of the external connections.
Page 20
20 Manual Skylla with universal input
4.8 Charging batteries with voltage sensing
When high current runs trough a thin cable between the charger and the battery there
will be a voltage loss in the cables. The charging voltage measured at the battery poles
will be lower than the specified voltage and this will result in a longer charging time.
However, the charger is equipped with a voltage sense facility. The battery voltage is
exactly measured and the charger increases the output voltage to compensate for the
voltage loss across the cables.
The charger can compensate for a maximum of 2V voltage loss over the cables. When
the voltage loss is bigger than 2V the “on” led flashes and the failure led illuminates. The
charge voltage will decrease until the voltage loss becomes maximum 2 Volt. The “on”
led flashes and the failure led illuminates until the charger is manually switched off.
When this occurs the battery cables have to be replaced because they are too thin or
have bad connections.
To install the voltage sense option:
Disconnect the mains.
Connect a red 0,75 mm2 wire to the positive battery pole and the “+Vse” connector
of the charger, see illustration 8.
Connect a black 0,75 mm2 wire between the negative pole of the battery and the “Vse” connector of the charger, see illustration 8.
For properly functioning both wires have to be connected.
Switch on the mains.
The “VSE OK” led on the printed circuit board illuminates when connected
correctly. If this led does not illuminate the voltage sense wires are wrongly
connected.
4.9 Intelligent startup
The factory setting of the charger is such that the battery voltage is
checked when the charger is switched on (intelligent startup). In the
case of a flat battery, the charger will start charging in the boost mode.
If the battery voltage is sufficiently high during charger startup, the
charger will be charging in the float mode.
In some situations it may be desirable for the charger not to check the
battery voltage upon startup. With this charger this function is
enabled by sliding dip switch 2 “Watch” to the left.
When this dip switch is positioned on the left, the charger will always
start charging in the boost mode.
Do not use the voltage sense facility in combination with the
diode-splitter compensation, as this will raise the output voltage.
Page 21
Manual Skylla with universal input 21
When dip switch 2 “Watch” is positioned on the right, it is checked upon startup
whether the battery voltage is sufficiently high to enable a start in the float mode. If it is
not, the charger is started in the boost mode as yet.
4.10 Connecting the output voltage alarm
The charger is equipped with a potential free alarm contact (change over type).
If the battery voltage is in between Vmin and Vmax the contact is activated.
(See figure 8, remote connections: NO, NC, COM).

Connect the switch in between the “REM” and the “GND” connector.
4.13 Connecting a remote boost switch
A remote switch can be connected to the charger so the charger can be switched
permanently into the boost-charge mode. Due to parallel loads connected to the
battery it is advised to switch the charger into the permanent boost-charging mode in
order not to discharge the battery.
If the switch is closed the charger switches into the permanent boost-charge mode. If
the switch is opened again the charger will automatically go to the float-charge mode.
This in order not to overcharge a battery with charging it to long with higher charging
voltage.

To connect the boost switch:
Disconnect the mains.
Connect one pole of the switch to the “RBOO” connector.
Connect the other pole of the switch to the “GND” connector.
4.14 Connecting a voltmeter
The remote-connector offers a possibility to connect a voltmeter. It is possible to
connect a digital as well as an analogue voltmeter. This output can only be used when
the voltage-sense is connected. The voltage at this output is equal to the voltage
measured at the point where the voltage sense wires are connected.
Connecting a voltmeter
Disconnect the mains voltage.
Make sure that the voltage sense wires are connected, see chapter 4.8.
Connect a black wire between the “-” connection of the voltmeter and “-VM” at the
remote connector.
Connect a red wire between the “+” connection of the voltmeter and “+VM” at the
remote connector.
Connect the mains voltage.
4.15 Connecting a ampèremeter
The remote connector offers a possibility to connect an ampèremeter, which indicates
the output current of the charger. For the 30A charger an ampèremeter, which indicates
30A at 60mV input voltage is required. For the 50A charger an ampèremeter, which
indicates 50A at 60mV input voltage is required, likewise for the 100A charger an
ampèremeter, which indicates 100A at 60mV input voltage is required.
Connecting an ampèremeter
Disconnect the mains voltage.
Connect a black wire between the “-” connection of the ampèremeter and “-AM” at
the remote connector.
Connect a red wire between the “+” connection of the ampèremeter and “+AM” at
the remote connector.
Connect the mains voltage.
