Product Overview
The Skylla-TG range from Victron Energy is engineered for professional battery charging in environments where reliability and compliance matter. The 24/50 variant delivers 50 amps into a 24V battery system, making it appropriate for medium to large battery banks found on commercial vessels, emergency backup systems, and off-grid installations. The GMDSS designation indicates this unit meets the specific requirements for safety communication systems mandated on regulated maritime vessels, which is a distinct requirement from standard marine chargers.
The 120 to 240V AC input range means the charger can operate from North American 120V supplies through to European and international 240V shore power or generator outputs without reconfiguration. This flexibility is particularly useful on vessels that move between different ports and power infrastructures. The Skylla-TG uses a multi-stage charging algorithm to condition, bulk charge, absorb, and float the battery bank, protecting battery health over long service periods.
At 7.4 kg, the unit is compact relative to its output class. Installation requires a qualified marine or electrical engineer, particularly given the GMDSS compliance requirements and the safety-critical nature of the systems it typically supports.

Installation Notes
This charger must be installed by a qualified marine electrician or electrical engineer. GMDSS installations on regulated vessels are subject to maritime authority inspection and approval, and incorrect installation can affect vessel certification. Ensure AC supply wiring, fusing, and battery cabling are correctly rated for the charger's input and output currents. Verify battery chemistry compatibility before commissioning. Do not attempt installation without appropriate qualifications and knowledge of the applicable maritime electrical standards.
