Victron Skylla-i 24/80 (3) battery charger 24v 80a

The Skylla-i 24/80 (3) from victron Energy (mpn ski024080002) is a powerful 24v battery charger for larger battery banks. It has 3 charging outputs and the maximum charging current of 80a can be freely distributed among the outputs. With the Skylla-i 24/80 (3) you can charge all common lead-acid batteries and of course also modern lithium-ion batteries.

flexible technology and robust constitution

The epoxy powder coated aluminum housing with drip protection and stainless steel brackets defy even the harshest environmental conditions: Heat, humidity and salty air. An acrylic coating provides the best possible protection for the circuit boards against corrosion. Temperature sensors ensure that the power components are always operated within the specified limits. Under extreme environmental conditions, the output current is automatically reduced if necessary

Apart from a can Bus (nmea2000) interface, a rotary knob, DIP switches as well as potentiometers are available to adapt the charging algorithm to a specific battery and its usage conditions. A total overview of the different possibilities can be found in the manual

the most important functions of the Skylla-i 24/80 (3)

Synchronized parallel operation

Multiple chargers can be synchronized with the can Bus interface. This is achieved by simply connecting the chargers together via rj45 utp cables. Please refer to the manual for more details.

The correct charge quantity for a lead-acid battery: adjusted constant voltage time

If only weak discharges occur, the constant voltage time is kept short to avoid overcharging the battery. After a deep discharge, the constant voltage phase is automatically extended to ensure that the battery is fully charged.

preventing damage due to excessive gas generation: Battery-saving mode

To shorten the charging time, the aim is to achieve the highest possible charging current in conjunction with a high constant voltage. However, to prevent excessive gassing towards the end of the constant current phase, the Skylla-i limits the rate of voltage rise once the gassing voltage has been reached.

Less maintenance and aging when the battery is at rest: the storage mode

The storage mode is activated whenever there has been no discharge within 24 hours. In storage mode, the charge retention voltage is then lowered to 2.2 v/cell (26.4 v for a 24 v battery) to minimize gassing and corrosion of the positive plates. Once a week, the voltage is increased back to the constant voltage threshold to 'refresh' the battery. This provides a type of equalization charge that prevents electrolyte stratification and sulfation, the two main causes of premature battery failure.

To extend the life of the battery: temperature compensation

A battery temperature sensor is supplied with each Skylla-i unit. The temperature sensor ensures that the charging voltage decreases as the battery temperature rises. This is especially important for gel batteries or when high temperature fluctuations are expected constantly.

Battery voltage sensor

To compensate for voltage losses due to cable resistance, the Skylla-i has a voltage sensor in the charging circuit so that the battery always receives the correct charging current.

Suitable for AC and DC supply (ac-dc and dc-dc operation)

The chargers can also be operated with a DC power supply.

use as a power source

Due to the perfectly stabilized output voltage, the Skylla-i 24/80 (3) charger can be used as a power source when batteries or large buffer capacitors are not available.

optional remote control panel and can bus connection

The Skylla-i 24/80 has an optional remote control panel which offers extensive control possibilities of the Skylla-i. The can Bus connection also allows the integration of the battery charger into larger system networks that need to be centrally monitored and controlled.
