Installation and wiring
Skylla-IP65
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.
1. Disconnect the mains supply
2. Disconnect battery cables from the battery.
3. Remove the grey cover in the front panel of the charger, enabling access to the terminals.
4. Connect battery cables to the charger:
plus (red) to “+BAT1”;
minus (black) to “-BAT”
5. Connect battery cables to the battery:
plus (red) to positive pole,
minus (black) to negative pole.
6. Connect the mains supply.
2.2.2. Main battery disconnection sequence
When disconnecting the battery cables, be very careful not to accidentally
short circuit the battery.
1. Disconnect the mains supply. 2. Disconnect battery cables from the
battery. 3. Remove the grey cover in the front panel of the charger, enabling
access to the terminals. 4. Disconnect the battery-cables from the charger. 5.
Disconnect all other cables like temperature sensor and/or voltage sensor used
with this particular battery.
2.3. 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.
2.4. VE.Can connection
The two VE.Can connectors provide access for parallel synchronised parallel
operation and remote control.
2.4.1. 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.
Page 3
Installation and wiring
Skylla-IP65
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.
2.4.2. 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.
2.5. 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.
2.5.1. 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”
2.5.2. 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”
Page 4
Installation and wiring
Skylla-IP65
· 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
2.5.3. 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.
2.5.4. 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.

4.2.1. 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).
4.2.2. 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.

Operation
Skylla-IP65
4.2.3. 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.
4.2.4. 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. 4.2.5. 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. 4.2.6. 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. 4.2.7. Weekly battery

4.3.1. 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).
4.3.2. Absorption
After the absorption voltage has been reached, the charger operates in
constant voltage mode. The recommended absorption time is 2 hours.
4.3.3. 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.
4.3.4. 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.

Description battery temperature too high
battery voltage too high temp. sense error
voltage sense error charger temperature too high
Internal error charger bulk time expired Fan failure
Internal error No input voltage (only for the three output version) charger
disappeared during operation Incompatible device
BMS connection lost
Internal error
Internal error Settings invalid
Possible cause Overcharging or fast charging
Wiring mistake, or another charger is over charging Wiring mistake or
temperature sensor broken
Wiring mistake The heat generated by the charger cannot be removed
After 10 hours of bulk charging, the battery voltage has still not reached the
absorption voltage. This error indicates that the fan is powered on but the
circuit does not measure any current draw by the fan. Most likely the fan is
either broken or obstructed.
Mains removed or ac-input fuse blown
Solution Check air flow near the battery Improve cooling of environment. The
charger stops automatically and will resume once the battery has cooled down
Check all charging equipment. Check cables and connections Check the
temperature sensor wiring and if that doesn’t help replace the temperature
sensor Check the voltage sensor wiring. Check air flow of the cabinet. Improve
cooling of environment. The charger stops automatically and will resume once
the charger has cooled down. Contact your dealer Possible cell failure or
higher charge current needed.
Contact your dealer
Contact your dealer Check mains availability and fuse.
One of the other chargers with which this charger was synchronizing has
disappeared during operation The charger is being paralleled to another
charger that has different settings and/or a different charge algorithm
Connection to the BMS lost
Communication error
To clear the error, switch the charger off and back on.
Make sure all settings are the same and update firmware on all chargers to the
latest version.
Check the VE.Can bus cabling. When the charger needs to operate in standalone
mode again, go to the setup menu #31 (BMS Present) and set to N. Contact your
dealer Check wiring and terminators Contact your dealer
Restore defaults in the setup menu #62.
