It is suited to off-grid systems, marine installations, and large battery banks where a compact, robust charger is needed.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e48V output at 25A continuous charge current for large battery banks.\u003c\/li\u003e\n  \u003cli\u003eSingle-phase 230V AC input with wide input voltage tolerance.\u003c\/li\u003e\n  \u003cli\u003eAdaptive 4-stage charge algorithm: bulk, absorption, float, and storage.\u003c\/li\u003e\n  \u003cli\u003eTemperature-compensated charging via optional sensor to protect battery life.\u003c\/li\u003e\n  \u003cli\u003eCompact, wall-mountable enclosure weighing 5.5 kg.\u003c\/li\u003e\n  \u003cli\u003eCompatible with Victron VE.Bus and system monitoring via optional interfaces.\u003c\/li\u003e\n  \u003cli\u003eSuitable for lead-acid battery chemistries including AGM, gel, and flooded.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eProduct Overview\u003c\/h3\u003e\n\u003cp\u003eThe Skylla-TG range is Victron's high power transformer-based charger series. Unlike switch-mode chargers, the transformer-based design provides galvanic isolation and high tolerance to poor or unstable AC input quality, making it well suited to generator-fed systems, marine shore power, and industrial environments where mains quality cannot be guaranteed.\u003c\/p\u003e\n\n\u003cp\u003eThe 48\/25 model delivers 25A at 48V, providing up to 1,200W of charge power. The adaptive charge algorithm adjusts absorption time based on the previous discharge, which reduces unnecessary gassing and extends battery service life. The storage mode drops the voltage to a low maintenance level when the battery remains connected for extended periods without cycling.\u003c\/p\u003e\n\n\u003cp\u003eThe unit accepts a single-phase 230V AC supply and is designed for permanent installation. It can be integrated into larger Victron systems using optional monitoring accessories, and the (1+1) designation indicates the unit supports a parallel output configuration for increased charge current when two units are used together.\u003c\/p\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable style=\"border: 2px solid #f87c24; border-collapse: collapse; width: 100%;\"\u003e\n  \u003ctr style=\"background-color: #f87c24; color: #ffffff;\"\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e\u003cstrong\u003eValue\u003c\/strong\u003e\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSKU\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eSDTG4800251\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Voltage\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e48V\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eOutput Current\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e25A\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eAC Input Voltage\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e230V single phase\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eWeight\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e5.5 kg\u003c\/td\u003e\n  \u003c\/tr\u003e\n  \u003ctr\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003eGTIN\u003c\/td\u003e\n    \u003ctd style=\"border: 1px solid #f87c24; padding: 8px;\"\u003e8719076025801\u003c\/td\u003e\n  \u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eOff-grid battery systems with 48V battery banks requiring high-current charging.\u003c\/li\u003e\n  \u003cli\u003eMarine vessels with 48V house battery systems connected to shore power or a generator.\u003c\/li\u003e\n  \u003cli\u003eIndustrial and telecoms backup power installations.\u003c\/li\u003e\n  \u003cli\u003eGenerator-fed charging where AC input quality is variable.\u003c\/li\u003e\n  \u003cli\u003eParallel charging configurations using two Skylla-TG 48\/25 units for increased output.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eWhat Is Included\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e1x Victron Skylla-TG 48\/25 (1+1) 230V battery charger\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3 style=\"color: #f87c24;\"\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe Skylla-TG 48\/25 must be installed by a qualified electrician.
