The Victron Skylla-IP65 24/35(3) is a three-output battery charger built for marine and professional installations where several battery banks need charging from one AC source. It delivers 35A at 24V across three independent output channels, and its IP65 enclosure copes with dust and low-pressure water jets, making it suitable for a marine battery charger role on boats and vehicles alike.

Key features for marine battery charger use

• Output, 35A at 24V across three separate channels for independent battery bank charging.
• Enclosure, IP65 rated against dust ingress and low-pressure water jets.
• AC input, 120-240V range, covering UK, European and North American supplies.
• Charging algorithm, adaptive four-stage bulk, absorption, float and storage profile.
• Battery compatibility, selectable profiles for flooded, gel and AGM lead-acid types.
• Temperature compensation, adjusts charge voltage according to battery temperature.
• Housing, aluminium enclosure weighing 6.5 kg for fixed installation.

Applications

The three-output design suits vessels with a main bank plus auxiliary banks, such as a bow thruster battery and a domestic supply, each charged to its own profile without cross-interference. Motorhomes and commercial vehicles with 24V systems, off-grid cabins running on generator or shore power, and industrial equipment in dusty or wet conditions all fall within its intended use. The wide AC input tolerance also helps where generator voltage fluctuates.

Installation

Fitting should be done by a qualified electrician, with AC supply correctly fused and cable sizing on both AC input and DC output matched to the unit's current ratings. The three outputs connect to compatible 24V lead-acid battery banks; lithium batteries should only be connected once the charge profile has been confirmed suitable. Mount on a solid surface with good ventilation, even though the enclosure itself is sealed to IP65.
