Skylla-i 24/100 (1+1) 230V

The Skylla-i 24/100 (1+1) charger stands out with its two isolated outputs. The main output delivers 100A for the main battery bank, while the second output is limited to about 4A with a slightly lower voltage, specifically designed to maintain a starter battery. In contrast, the Skylla-i (3) models feature three full-rated outputs.

The Skylla-i 24/100 (1+1) is designed to withstand harsh marine environments thanks to its epoxy powder-coated aluminum housing with a drip-proof screen and stainless steel fasteners. Its printed circuit boards are protected by an acrylic coating for maximum corrosion resistance. Integrated temperature sensors automatically reduce the output current in extreme conditions to protect the components.

The Skylla-i 24/100 (1+1) charger provides a maximum charging current of 100A for the main battery bank. It also has a secondary output limited to approximately 4A for the starter battery.

Yes, the Skylla-i 24/100 (1+1) charger is compatible with lithium-ion (LiFePO4) batteries. It can be controlled via a simple on/off command by connecting a relay or an open-collector optocoupler from a Li-ion BMS to the charger's control port. Full voltage and current control is also possible via the galvanically isolated CAN bus port.

Yes, thanks to its perfectly stabilized output voltage, the Skylla-i can be used as a power supply if batteries or large buffer capacitors are not available.

The charger can operate within a temperature range from -20°C to 60°C. It will deliver full output current up to 40°C. Beyond that, output current will be reduced (80% at 50°C, and 60% at 60°C).

The charger uses a 7-stage adaptive algorithm to optimize charging. It adjusts absorption time based on depth of discharge to prevent overcharging. Additionally, the BatterySafe mode prevents damage from excessive gas release by automatically limiting voltage increase once the gassing voltage is reached.

The 'Storage' mode (storage) is activated if the battery has not been discharged for 24 hours. In this mode, the floating voltage is reduced to 2.2V/cell (26.4V for a 24V battery) to minimize gas release and corrosion of the positive plates. Once a week, the voltage is increased to the absorption level to 'refresh' the battery, preventing electrolyte stratification and sulfation.

Yes, the Skylla-i comes with a battery temperature sensor. When connected, the charging voltage automatically decreases as the battery temperature rises. This feature is particularly recommended for sealed lead-acid batteries and/or in cases of significant battery temperature fluctuations.

The Skylla-i 24/100 (1+1) charger operates with a nominal AC input voltage of 230V, with an operating range from 185V to 265V AC. It can also accept a DC supply between 180V and 350V DC.

The charger must be mounted in a dry and well-ventilated location. It can be wall-mounted or floor-mounted. A vertical installation is recommended as it improves air circulation inside the housing, thereby extending the charger's lifespan.

It is recommended to keep the cable length between the charger and the battery under 6 meters to minimize voltage losses and ensure proper charging.

The ground point must be connected to a true ground. Here’s how to proceed depending on the application:

On a vessel: connect it to the ground plate or the hull of the vessel.

For the Skylla-i 24/100 (1+1), the recommended cable cross-sections for the main battery are:

Up to 1.5 m cable length: 35 mm²From 1.5 m to 6 m cable length: 50 mm²The starter battery must be connected with a wire of at least 2.5 mm².

No, the Skylla-i is NOT protected against reverse battery polarity. It is critical to follow the installation procedure carefully to connect the positive (+) and negative (-) terminals correctly. Reverse polarity can damage the device and will void the warranty.

To connect an external voltage sensor, run a red wire (0.75 mm²) from the battery’s positive terminal to the '+ Voltage sensor' connector on the charger. Then connect a black wire (0.75 mm²) from the battery’s negative terminal to the '- Voltage sensor' connector. Ensure the corresponding LED lights up to confirm the connection.

Connecting the remote control switch requires careful attention. It is recommended to use twisted wires for this connection as the input is sensitive. If no remote control switch is connected, the on/off remote control terminals must be short-circuited with a short wire. This port can also be connected to a lithium battery management system (BMS) for control.

Yes, multiple Skylla-i chargers can be synchronized via the CAN bus interface (VE.Can). This is done by simply interconnecting the chargers with UTP RJ45 cables. However, it is important to note that (1+1) and (3) output chargers cannot be paralleled with each other.

Yes, the charger can be connected to an NMEA 2000 network via its VE.Can ports (RJ45). To do this, use the VE.Can to NMEA 2000 cable accessory and remove the fuse. Further details are available in the Victron Energy NMEA 2000 and MFD integration guide.

The charger is compatible with a wide range of batteries, including lead-acid batteries (flooded, GEL, AGM) and lithium-ion batteries (LiFePO4). Its 7-step adaptive charging algorithm is optimized for lead-acid batteries, and it features a 3-step algorithm with on/off control or CAN bus for Li-ion batteries. The recommended capacity is 500-1000Ah.
