Installation and wiring
Installation
Find a dry and well-ventilated area to mount the Skylla-IP65 charger and
battery. Keep the cable length between the charger and the battery less than 6
meters.
The charger may be wall or floor mounted. Always make sure that air may flow
freely at the back side of the cabinet. This will improve cooling of the
charger and prolong lifetime.
Wall mounting
The unit can best be mounted vertical to a wall. See appendix for exact
positions of the mounting holes.
Wiring
The inlets for the mains cable, the battery cables, the remote functions and
the connection to attach the earth cable are located at the bottom of the
housing; see markings on the front panel.
For best protection against water and dust from entering the case, all
openings in the grey terminal block should be closed, either with a suitable
cable or, when no connection is used, a dummy piece of cable.
Connecting earth Connect the earth point to the installation earth.
Connections to earth have to be according to applicable safety standards. · On
a ship: connect to the earth plate or to the hull of the ship.
- On land: connect to the earth of the mains. The connection to the earth of the mains has to be according to applicable safety standards.
- Mobile applications (a vehicle, a car or a caravan): Connect to the frame of the vehicle.
The battery connections of the charger are fully floating with respect to this grounding point
Connecting the main battery
Before the main battery is connected to the charger, make sure the charger is
set to the correct battery type. Minimum cable cross section between main
battery and charger:
Skylla-IP65 type| cable length up to 1.5 m| cable length 1.5 m –
6 m
---|---|---
12/70| 10 mm2| 16 mm2
24/35| 6 mm2| 10 mm2
The largest possible cable lug that will fit through the battery cable glands is size S6-16. That cable lug will suit a maximum cable diameter of 16 mm2 and fit on an M6 bolt.
Main battery connection sequence
The Skylla-IP65 is NOT protected against reverse polarity of the main battery.
(“+” connected to “-” and “-” connected to “+”). Follow the installation
procedure. The warranty expires when the Skylla-IP65 becomes defective due to
reverse polarity.
Disconnect the mains supply before making or breaking connections to the main
battery.
- Disconnect the mains supply
- Disconnect battery cables from the battery.
- Remove the grey cover in the front panel of the charger, enabling access to the terminals.
- Connect battery cables to the charger: plus (red) to “+BAT1”; minus (black) to “-BAT”
- Connect battery cables to the battery: plus (red) to positive pole, minus (black) to negative pole.
- Connect the mains supply.
Main battery disconnection sequence
When disconnecting the battery cables, be very careful not to accidentally
short circuit the battery.
- Disconnect the mains supply.
- Disconnect battery cables from the battery.
- Remove the grey cover in the front panel of the charger, enabling access to the terminals.
- Disconnect the battery-cables from the charger.
- Disconnect all other cables like temperature sensor and/or voltage sensor used with this particular battery.
Connecting the starter battery
The Skylla-IP65 is NOT protected against reverse polarity of the starter
battery. (“+” connected to “-” and “-” connected to “+”). Follow the
installation procedure. The warranty expires when the Skylla-IP65 becomes
defective due to reverse polarity. Disconnect the mains supply before making
or breaking connections to the main battery. The starter battery has to be
connected using wire of at least 1.5 mm2 (max. 6 mm2 ). Connect the positive
(+) battery-pole to the “Starter battery plus” connector, see Figure 1. The
negative pole of the starter battery has to be connected to the “-BAT”
connection of the charger. The starter battery can draw current from the
battery connected to the main battery terminals in case the voltage of the
starter battery is lower than the voltage main battery. However, the main
battery cannot draw current from the starter battery even when the starter
battery is fully charged and the main battery is at minimum charge level.
VE.Can connection
The two VE.Can connectors provide access for parallel synchronised parallel
operation and remote control.
Synchronised parallel operation
Several charge controllers can be synchronized with the CAN interface to a
maximum of 10 chargers. This is achieved by simply interconnecting the
chargers with RJ45 UTP cables (bus terminators needed. The paralleled charge
controllers must have identical settings (e.g. charge algorithm). The CAN
communication ensures that the controllers will switch simultaneously from one
charge state to another (from bulk charge to absorption for example).The
output current of one charger may differ from another charger although
connected in parallel.In case of using remote sensors (voltage and/or
temperature), the remote sensor needs to be connected to one of the parallel
operating chargers. All other chargers will share the information via the CAN
interface. In case of synchronised parallel operation, the network icon will
blink every 3 seconds on all paralleled units.
Input/shore current limit
The AC input current limit of each charger is set to 10,5 A max and can be
adjusted with a CCGX device, NMEA 2000 or a Skylla-i-control GX remote panel.
See https://www.victronenergy.com/panel-systems-remote-monitoring/skylla-i
-control-gx The input power of one charger will never be more than 1050 W.
This means that at 100V AC in the input current is max 10,5 A, and at 230V AC
the maximum input current is 4,5 A. The input current limit of a parallel
charger group can be set with a CCGX device or with a Skylla-i-control GX
remote panel. The current limit as shown on the device is the shore current of
the group.
User relay, external sense and remote shut down
The wiring of these signals must be done with the mains disconnected from the
charger.
Figure 1 Connectors for external voltage/temperature sensing, Rem. Shut down, VE.Can bus and Starter battery.
External voltage sense
External voltage sensing may be used when accurate battery voltage sensing is
important, such as high charging currents in combination with long cables. To
connect the external voltage sensing option, proceed as follows: · connect a
red wire (0.75 mm2 ) between the positive battery terminal and connector “+
Volt. sense” · connect a black wire (0.75 mm2 ) between the negative battery
terminal and connector “- Volt. sense”
External temperature sense
The external temperature sensor, supplied with the charger, can be connected
to these terminals in order to perform temperature compensated charging of the
battery. The sensor is electrically isolated and must be connected to the
positive or negative pole of the battery. To connect the temperature sensor,
proceed as follows:
- connect the red wire to connector “+ Temp. sense”
- connect the black wire to connector “
- Temp. sense” – mount the temperature sensor on the positive or negative pole of the battery
- check in the menu for the actual temperature
Remote shut down
From factory the remote + and – are connected together with a jumper wire to
turn the charger on. In order to use the remote to shutdown the charger,
remove the jumper and connect a wire to “remote -” input. Switching the
“remote -” input to battery voltage causes the charger to turn on. This wire
can be used to connect to a BMS used for lithium batteries to control the
charger.
User relay connections
The user relay is triggered by a battery under-voltage situation (<11.8 V).
The function may be used for any desirable action: starting a generator,
sounding an alarm etc. The ratings of the relay can be found in the
specification.

Pressing setup shortly will return to the setup menu. When setup is completed, exit the menu by pressing “SETUP” again three seconds.
Battery selection
The charge algorithm of the charger must fit the battery type connected to the
charger. The following table shows all the predefined battery types available
in the charge algorithm selection menu.
Power supply mode
The charger can be set to operate as a DC power supply. In this mode, the
charger functions as a constant voltage source: 1. an adjustable output
voltage of 8.0 to 15.9 V (12 V type) resp. 16.0 to 31.8 Volt (24 V type) 2. a
maximum output current of 60A (12 V type) resp. 30A (24 V type).
Temperature compensation (dV/dT)
The temperature sensor should be connected to the plus or negative pole of the
battery. The temperature compensation is a fixed setting, see table and fig.
4, and applies to all charge states. The temperature sensor must be installed
when:
- ambient temperature of the battery is expected to regularly be lower than 15 °C or to regularly exceed 30 °C
- charge current exceeds 15 A per 100 Ah battery capacity Temperature compensation is not required for Li-Ion batteries.
Power Control maximum use of limited shore current
A maximum mains current can be set in order to avoid interruption of an
external fuse in the mains supply.
Operation

Figure 3 Voltage and current during different states in battery charging.
Bulk
Entered when the charger is started or when the battery voltage falls below
13.2 V / 26.4 V (due to a heavy load) during at least 1 minute. Constant
current is applied until gassing voltage is reached (14.4 V / 18.8 V).
Battery Safe
If absorption voltage is set higher than 14.4 V / 18.8 V, the rate of voltage
increase beyond 14.4 V / 18.8 V is limited to 7mV/14mV per minute, in order to
prevent excessive gassing.
Absorption
After the absorption voltage has been reached, the charger operates in
constant voltage mode. In case of adaptive charging, the absorption time is
dependent on the bulk time, see section 3.2.
Automatic equalization
If automatic equalization has been set to `on’, the absorption period is
followed by a second voltage limited constant current period: see section 3.3.
This feature will charge VRLA batteries to the full 100 %, and prevent
stratification of the electrolyte in flooded batteries. Alternatively, manual
equalization can be applied.
Float
After float charge the output voltage is reduced to storage level. This level
is not sufficient to compensate for slow self-discharge of the battery, but
will limit water loss and corrosion of the positive plates to a minimum when
the battery is not used.
Storage
After float charge the output voltage is reduced to storage level. This level
is not sufficient to compensate for slow self-discharge of the battery, but
will limit water loss and corrosion of the positive plates to a minimum when
the battery is not used.
Weekly battery `refresh’
Once a week the charger will enter Repeated Absorption-mode during one hour to
‘refresh’ (i. e. to fully charge) the battery

Bulk
Entered when the charger is started, or when the battery voltage falls below
13,5 V / 27,0 V (due to a heavy load) during at least 1 minute. Constant
current is applied until absorption voltage is reached (14.2 V / 28.4 V).
Absorption
After the absorption voltage has been reached, the charger operates in
constant voltage mode. The recommended absorption time is 2 hours.
Storage
After absorption charge the output voltage is reduced to storage level. This
level is not sufficient to compensate for slow selfdischarge of the battery,
but will maximize service life.
Weekly battery `refresh’
Once a week the charger will enter Repeated Absorption-mode during one hour to
‘refresh’ (i. e. to fully charge) the battery.
Maintenance
This charger does not require any specific maintenance. However an annual check of the battery and mains connections is recommended. Keep the charger dry, clean and free of dust.
