The Victron Smart IP43 Charger 12/30(3) is a three-output mains battery charger for 12V battery banks, delivering 30A total output across its three independently controlled outputs. It accepts AC input from 120 to 240V, so the same unit works on UK, European and North American mains supplies. It suits professional installers, marine and vehicle work, and off-grid systems that need monitored, reliable charging.

Key features

• Charge output, 30A across three independent outputs for simultaneous charging of separate 12V battery banks.
• AC input range, 120 to 240V, covering UK/EU and North American mains standards.
• Connectivity, built-in Bluetooth links to the VictronConnect app for monitoring, configuration and charge profile adjustment.
• IP43 rating, protected against solid objects greater than 1mm and water spray up to 60 degrees from vertical.
• Charging algorithm, adaptive, multi-stage, with temperature compensation.
• Battery compatibility, AGM, gel, flooded lead-acid and lithium (with a suitable BMS).
• Storage mode, reduces float voltage after 24 hours to limit degradation during long-term storage.

Product overview

The charger monitors battery behaviour during the bulk phase and adjusts absorption time accordingly, so a deeply discharged battery gets a full cycle while a partially discharged one is not held on unnecessary absorption. The three outputs are independently controlled, useful where a starter battery, a domestic bank and an auxiliary battery all need maintaining at once. Bluetooth is built in, so VictronConnect connects without extra hardware, showing charge status, history and configuration. At 3.7kg it fits confined spaces such as engine rooms, battery compartments or vehicle lockers.

Applications

Used on marine vessels charging starter, domestic and bow thruster banks together, in motorhomes and campervans with multiple 12V systems, in off-grid cabins with a mains hook-up, on commercial vehicle fleets needing app-based condition checks, and in workshops maintaining stored batteries over time.

Installation notes

Fit to a correctly fused mains supply by a qualified electrician, following local wiring regulations, with adequate ventilation around the unit. IP43 gives limited water protection only, so avoid locations subject to direct water ingress or submersion. Confirm a compatible BMS is fitted before connecting lithium batteries, and complete the VictronConnect configuration before commissioning so the right charge profile is selected.
