The Victron Skylla-TG 24/30 and 24/50 GMDSS battery chargers are designed to provide all the necessary monitoring and alarm data. Both the battery and the GMDSS system are connected directly to the charger. All data and alarms are displayed on a digital panel (VE.Net GMDSS panel, to be ordered separately). A standard eight-core UTP network cable connects the charger and the panel.
