Description
xVictron Skylla-TG 24/80 (1+1) 230V High Power Battery Charger
The Victron Skylla-TG 24/80 (1+1) is a high-power, three-phase compatible battery charger designed for professional and industrial applications. It delivers 80A of charge current at 24V, with a (1+1) dual output configuration that allows simultaneous charging of two independent battery banks. Built for demanding environments where reliability and precise charge management are non-negotiable.
Key Features
- 80A charge current at 24V nominal output, suitable for large battery banks in commercial and industrial systems.
- (1+1) dual output configuration allows two separate battery banks to be charged independently from a single unit.
- 230V AC input for compatibility with standard single-phase mains supply.
- Adaptive charge algorithm automatically adjusts to battery condition, extending battery service life.
- Temperature-compensated charging ensures correct charge voltage across varying ambient conditions.
- Victron VE.Bus compatible, enabling integration with Victron monitoring and control systems.
- Robust metal enclosure rated for professional installation in fixed plant and marine environments.
Product Overview
The Skylla-TG series is Victron's range of high-power transformer-based battery chargers, intended for professional use in marine, industrial, and off-grid power systems. The 24/80 variant outputs up to 80A at 24V, making it appropriate for large lead-acid or gel battery banks where fast, accurate recharging is required. The (1+1) designation means the unit provides two independent charge outputs: one primary 80A output and one auxiliary output, allowing a secondary battery bank (such as a starter battery) to be maintained simultaneously without a separate charger.
The adaptive multi-stage charge algorithm moves through bulk, absorption, and float phases based on actual battery response rather than fixed timers. This approach reduces the risk of overcharging and sulphation, which is particularly relevant in standby and backup power applications where batteries may sit at float for extended periods. Temperature compensation adjusts the charge voltage automatically, which matters in installations where ambient temperature varies significantly, such as engine rooms or outdoor enclosures.
VE.Bus connectivity allows the Skylla-TG to be monitored and configured via Victron's GX devices and VictronConnect software. This is useful in larger systems where charge status needs to be visible alongside inverter and solar data on a single dashboard. The unit is designed for fixed installation and is not intended as a portable or consumer-grade charger.

Installation Notes
The Skylla-TG 24/80 is a fixed-installation charger and should be installed by a qualified electrician familiar with battery systems and DC wiring. Ensure the AC supply is correctly fused and that DC output cabling is sized appropriately for 80A continuous current. Battery bank connections must be made with correct polarity and appropriate DC fusing on each output. In marine installations, comply with applicable ABYC or ISO wiring standards. If integrating with a Victron VE.Bus system, configuration should be carried out using VictronConnect or a compatible GX device before commissioning.
