Victron Energy - 24V - 100A Skylla-i 24/100 (1+1) 230VAC/45-65Hz Battery Charger

Victron Skylla-i 24/100 (1+1): Professional 24V 100A Battery Charger for Marine, Off-Grid, and Industrial Applications

Advanced Multi-Stage Charging with Dual Isolated Outputs

The Victron Skylla-i 24/100 (1+1) is a high-performance 24V 100A battery charger engineered for demanding environments where reliability and precise charge control are critical. Featuring two isolated outputs, it delivers a full 100 A to the main battery bank while providing a dedicated 4 A output to maintain a starter battery, making it an ideal solution for marine battery charging, off-grid power systems, and industrial backup applications.

Built on Victron's proven Skylla-i platform, this charger combines adaptive 7-stage charging with advanced communication capabilities, ensuring optimal battery health and longevity for lead-acid and lithium-ion chemistries alike.

Intelligent Adaptive Charging for Maximum Battery Life

Unlike conventional chargers with fixed absorption times, the Skylla-i employs variable absorption technology that automatically adjusts the charge cycle based on depth of discharge. After shallow discharges, absorption time is minimised to prevent overcharging; following deep discharges, it extends to ensure complete recharge. This adaptive approach significantly reduces battery wear and extends service life.

The integrated BatterySafe mode prevents excessive gassing by limiting voltage rise once the gassing threshold is reached, protecting sealed batteries from damage during high-current charging. For extended idle periods, the Storage mode reduces float voltage to 26.4 V and performs a weekly refresh cycle to prevent electrolyte stratification and sulphation, two leading causes of premature battery failure.

Rugged Construction for Harsh Environments

Encased in a durable aluminium housing with epoxy powder coating and a drip shield, the Skylla-i is purpose-built to withstand heat, humidity, and salt-laden air. Stainless steel fixings and acrylic-coated circuit boards provide superior corrosion resistance, while internal temperature sensors automatically derate output current under extreme conditions to protect power components. This makes it a trusted choice for marine battery chargers and coastal installations.

Flexible Configuration and System Integration

Setup is straightforward via a rotary switch, DIP switches, and potentiometers, allowing precise adaptation to specific battery types and operating conditions. For advanced integration, the VE.Can (NMEA2000) interface with dual RJ45 connectors enables synchronised parallel operation of multiple chargers, remote monitoring, and full CAN bus control for lithium-ion battery management systems.

The charger also supports voltage sense to compensate for cable losses, ensuring the battery receives the correct charge voltage regardless of installation distance. A remote on/off port allows direct connection to a Li-Ion BMS for simple charge control.

Designed for Demanding Applications

Whether you are maintaining a large house bank on a cruising yacht, powering a remote telecommunications site, or building a resilient off-grid energy system, the Skylla-i 24/100 delivers the precision and durability required. Its ability to operate from both AC and DC sources adds flexibility for hybrid installations, while the IP21-rated enclosure with forced cooling ensures reliable performance in engine rooms and equipment shelters.

With a power factor of 0.98 and high efficiency, this charger minimises generator run time and reduces energy costs compared to less sophisticated units. The M8 bolt battery connections (approx. 8 mm) and screw-clamp AC terminals (10 mm² or AWG 7) simplify installation with heavy-duty cabling.
