xSkylla-TG 24/30 (1+1) GL Battery Charger 120-240V
The Victron Skylla-TG 24/30 is a high-power battery charger designed for professional and industrial applications where reliability and precise charge control are essential. Rated at 30A output on a 24V system, it suits marine, vehicle, and off-grid installations requiring a dependable bulk charging source. The (1+1) configuration provides a main output plus a dedicated starter battery output.
Key Features
- 30A charge current output on a 24V battery bank, with a separate 4A output for a starter or auxiliary battery.
- Wide AC input voltage range of 120 to 240V, making it compatible with both North American and European shore power supplies.
- Four-stage adaptive charging algorithm (bulk, absorption, float, storage) to maximise battery life and charge efficiency.
- GL certification confirms compliance with relevant international safety standards for marine and industrial use.
- Compact and robust aluminium enclosure rated for demanding environments, with a weight of 5.4kg.
- Compatible with Victron VE.Bus and monitoring accessories for system integration and remote oversight.
Product Overview
The Skylla-TG series sits within Victron's range of transformer-based high-power chargers. Unlike switch-mode chargers, the transformer-based design provides galvanic isolation between the AC input and DC output, which is a requirement in many marine classification rules and industrial installations. The 24/30 variant delivers 30A to the main battery bank and a separate 4A to a starter battery, allowing both banks to be maintained simultaneously without cross-contamination of charge states.
The wide input voltage range of 120 to 240V AC means the unit can be connected to shore power in the UK, Europe, or North America without modification. The four-stage adaptive charge algorithm adjusts absorption time based on the previous discharge, which reduces stress on the battery and extends service life compared to fixed-time charging. The GL mark confirms the unit has been tested to recognised international safety standards, which is relevant for vessels operating under classification society rules.

Installation Notes
Installation should be carried out by a qualified electrician or marine electrical engineer familiar with battery charging systems. Ensure the AC supply is correctly fused and that cable sizing is appropriate for the 30A DC output. On marine installations, follow the relevant classification society guidelines and verify that the GL certification meets your vessel's requirements. The unit accepts 120 to 240V AC input, but confirm the supply frequency and voltage are within the specified range before connecting. Do not install in locations exposed to direct water ingress.
