The Victron Smart IP43 Charger 24/25(3) is a three-output mains battery charger for professional and commercial charging where several battery banks need power from a single unit. It accepts 120 to 240V AC, so it works across UK, European and North American mains supplies without manual switching.

Key features

• Output, 24V at 25A total charge current, split across three independent outputs.
• AC input, 120 to 240V, accepted automatically regardless of shore power standard.
• Enclosure, IP43 rated, protected against solid objects over 1mm and water spray up to 60 degrees from vertical.
• Connectivity, built-in Bluetooth via Victron SmartConnect for setup and monitoring through the VictronConnect app.
• Charging algorithm, adaptive 7-stage profile with battery-safe mode, recondition mode and storage mode.
• Battery compatibility, GEL, AGM, tubular plate, flooded lead-acid and LiFePO4.

Product overview

A microprocessor-controlled adaptive algorithm adjusts the charge parameters based on how the battery behaves during the cycle rather than applying a fixed profile. That matters in marine and vehicle use, where battery condition varies between service intervals. The three outputs let each battery bank, starter, service or auxiliary, be charged separately while the unit manages current distribution between them.

Bluetooth monitoring through VictronConnect shows charge status, voltage, current and temperature (with a sensor connected) from a phone or tablet, without a separate dongle. The IP43 rating suits engine rooms, battery compartments and other semi-protected spaces where some moisture is possible but direct water contact is not expected.

Applications

• Marine installations charging starter, service and auxiliary banks together.
• Motorhomes and coaches with 24V systems on shore power.
• Off-grid cabins with periodic mains access for charging.
• Commercial 24V vehicle fleets needing overnight charging.
• Industrial equipment with multiple battery banks on one charger.

Installation notes

Install to BS 7671 wiring regulations with a qualified electrician. Protect the AC supply with a correctly rated circuit breaker and fuse each DC output at the battery. For marine installations, follow the relevant RCD and shore power connection requirements. Check the battery chemistry setting in VictronConnect before first use, especially for LiFePO4, since the wrong profile can damage the battery or shorten its life.
