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 approximately 4A with a slightly lower voltage, specifically designed to maintain a starter battery. The Skylla-i (3) models, on the other hand, offer three outputs at full rated current.

The Skylla-i 24/100 (1+1) is designed to withstand marine environments thanks to its epoxy powder-coated aluminum housing with a drip-proof screen and stainless steel fastenings. 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 features 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 of -20°C to 60°C. It will provide the full output current up to 40°C. Beyond that, the output current will be reduced (80% at 50°C, and 60% at 60°C).

The charger uses a 7-step 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 activates if the battery has not undergone discharge for 24 hours. In this mode, the float voltage is reduced to 2.2V/cell (26.4V for a 24V battery) to minimize gas release and positive plate corrosion. Once per week, the voltage is increased to the absorption level to 'refresh' the battery, preventing electrolyte stratification and sulfation.

Yes, the Skylla-i is supplied with a battery temperature sensor. When connected, the charging voltage automatically decreases as the battery temperature rises. This function 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 installed in a dry and well-ventilated area. It can be mounted on a wall or on the floor. 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 proper 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.
On land: connect it to the electrical grid ground, in compliance with applicable safety standards.
Mobile applications (vehicle, caravan): connect it to the vehicle’s chassis.
The charger’s battery connections are fully floating with respect to this ground point.

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

Cable length up to 1.5 m: 35 mm²Cable length from 1.5 m to 6 m: 50 mm²The starter battery must be connected with a wire of at least 2.5 mm².

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

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

Connecting the remote switch requires special attention. It is advisable to use twisted wires for this connection as the input is sensitive. If no remote 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 RJ45 UTP cables. However, it is important to note that chargers with (1+1) and (3) outputs 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, you must use the VE.Can to NMEA 2000 cable accessory and remove the fuse. Additional 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.
