The Victron Smart IP43 Charger 48/13 is a single-output mains battery charger for 48V battery banks. It accepts a wide AC input range of 120 to 240V, so the same unit works across UK, European and North American mains supplies. Installers and off-grid system integrators use it where a monitored, Bluetooth-enabled charge source is needed for 48V systems.

Key features

• Output, 48V at 13A charge current through a single output channel.
• AC input range, 120 to 240V AC, covering UK/EU and North American mains.
• Connectivity, built-in Bluetooth with the VictronConnect app on iOS and Android.
• IP rating, IP43, protected against solid objects over 1mm and water spray up to 60 degrees from vertical.
• Charging algorithm, adaptive, with automatic battery type detection and configurable absorption and float voltage.
• Storage mode, reduces float voltage after 24 hours to limit stress during long-term standby.

Product overview

The Smart IP43 range uses a multi-stage adaptive charging algorithm. After bulk charging it enters absorption and monitors battery acceptance current, then transitions to float once current drops below a set threshold. Battery type presets cover AGM, gel, lithium (LiFePO4) and flooded lead-acid, and custom profiles can be programmed for other chemistries. Temperature-compensated charging is available with an optional battery temperature sensor.

VictronConnect gives access to charge settings, real-time status and historical data without extra hardware. The wide AC input range means one unit serves UK and EU installations without modification. The IP43 rating suits plant rooms, battery enclosures and light-industrial spaces with some dust or moisture exposure, but it is not rated for outdoor or fully wet locations.

Applications

• Charging 48V lead-acid or LiFePO4 battery banks in off-grid solar systems.
• Standby and maintenance charging for 48V telecom and UPS installations.
• Shore power battery charging on narrowboats, yachts and other 48V marine systems.
• Light commercial and industrial backup power systems needing a monitored 48V charge source.
• Installations requiring dual-voltage mains compatibility (120V and 240V AC).

Installation notes

Installation should be carried out by a qualified electrician. Check the AC supply is correctly fused and that battery bank voltage matches the 48V output before connecting. For LiFePO4 batteries, confirm the charge profile is set correctly in VictronConnect. The IP43 rating does not permit outdoor exposure or locations subject to water ingress. Mains cord requirements vary by country, so confirm the correct plug and cable standard for the installation site.
