Professional battery charging for marine, industrial and standby power systems

Victron Skylla-TG 48/50 (1+1) is engineered for dependable battery charging in demanding applications where stable DC supply, battery health and clear system status all matter. Designed for 48V marine, industrial, and backup power systems, it combines a proven three-step IUoUo charging profile with robust protection features to support reliable operation across a wide range of installation environments in Australia.

For operators managing house batteries, service banks, standby systems or mission-critical DC loads, this charger helps reduce common charging issues such as undercharging, unnecessary battery stress and unstable supply voltage. The controlled charging process moves through bulk, absorption and float stages to better support battery condition over time while maintaining practical day-to-day usability.

A key advantage is its ability to function as both a battery charger and a DC power supply. This is particularly useful where onboard equipment, communications hardware, control systems or other DC loads need a steady source of power while the battery bank remains properly maintained. For installations that demand continuity and cleaner system integration, this can simplify the electrical setup and reduce the need for separate devices.

The front panel LED indicators provide at-a-glance visibility of output voltage, output current and charging status, making it easier to monitor charger behaviour without external tools. This is valuable for installers, fleet operators and vessel owners who need quick confirmation that the charger is operating as expected.

Built for real-world operating conditions, the unit features forced cooling and multiple protective functions, including safeguards for output short circuit, reverse polarity detection, high battery voltage and excessive temperature. These features help reduce the risk of charger shutdowns, wiring mistakes causing damage, and battery system stress in hard-working installations.

The aluminium enclosure is suited to fixed installation use and supports reliable operation in workshops, plant rooms, marine electrical systems and other enclosed service areas. With support for a broad input supply on applicable versions, it can suit installations where mains availability or onboard supply conditions vary.

Why this charger suits demanding installations

In marine, emergency, off-grid support and industrial backup applications, charger quality affects more than charge time alone. A well-designed charger can help improve battery service life, support connected loads more consistently and reduce the likelihood of nuisance issues caused by unstable charging behaviour. That is where Victron Skylla-TG 48/50 (1+1) stands apart from lower-grade alternatives that may offer limited protection, less stable output or less suitable charging control for continuous-duty use.

If your system needs a charger that can maintain battery readiness, support essential DC equipment and provide straightforward visual status feedback, this unit is a practical fit for professional installations. For 48V marine, industrial, and backup power systems, it offers a strong balance of charging performance, installation flexibility and operational confidence.

If you are building or maintaining a reliable DC power system, Victron Skylla-TG 48/50 (1+1) is a solid choice for keeping your batteries charged and your equipment ready for service.
