Smart nabíječka IP43 12/50 (1+1)

This Victron Energy Smart IP43 12/50 (1+1) 120/240V charger is a smart charger designed for demanding marine applications. It provides a main output of 50 amps for a house bank and a secondary output of 4 amps for a starter battery. It features a 6-stage adaptive charging algorithm, Bluetooth Smart connectivity, and a VE.Direct interface for monitoring and control. It is cooled by natural convection and compatible with various battery types, including LiFePO₄.

This Victron Energy Smart IP43 12/50 (1+1) 120/240V charger delivers a maximum charging current of 50 amperes for the house battery. The second output dedicated to the starter battery is limited to approximately 4 amperes.

The Smart IP43 Charger 12/50 (1+1) model is designed to charge two battery banks simultaneously. It has a main output for the house bank and a secondary output for a starter battery.

The second charge output, labeled (1+1), is limited to approximately 4 amps and has a slightly lower output voltage. It is specifically designed for maintaining and charging a starter battery, while the main 50-amp output is dedicated to the house bank.

The Victron Energy Smart IP43 12/50 (1+1) 120/240V charger is cooled by natural convection, meaning it has no fan.

This charger uses a 6-stage adaptive charging algorithm:

Bulk (bulk charge)AbsorptionReconditioningFloat (float charge)Storage (storage)Refresh (refresh)This algorithm automatically optimizes the charging process based on battery usage.

Yes, the BatterySafe mode is included. It prevents damage from excessive gas release by limiting the rate of voltage increase once the gassing voltage is reached, even if a high charge current and high absorption voltage have been selected.

The Storage mode activates when the battery has not been discharged for 24 hours. In this mode, the float voltage is reduced to 13.2 V for a 12 V battery to minimize gassing and positive plate corrosion. Once a week, the voltage is raised to the absorption level to "equalize" the battery, preventing electrolyte stratification and sulfation.

Yes, this charger can be used as a power supply. The output voltage can be adjusted via Bluetooth and/or the VE.Direct interface.

The dimensions of the Victron Energy Smart IP43 12/50 (1+1) charger are 180 mm (height) x 249 mm (width) x 116 mm (depth). Its weight is 2.7 kg.

This charger can operate within a temperature range from -20 °C to 60 °C. The nominal output current is maintained up to 40 °C, then it is linearly reduced to 20 % at 60 °C.

The protection rating of this charger is IP43 for the electronic components and IP22 for the connection area.

Yes, this charger is compatible with Li-ion batteries (LiFePO₄). It features a dedicated charging algorithm for these batteries, which can be configured via Bluetooth or VE.Direct. The on/off control of the charger can also be implemented by connecting a relay or an optocoupler open-collector output from a Li-ion BMS to the remote on/off port.

The adaptive battery management system of this charger is compatible with most common lead-acid battery types, such as flooded, AGM, and Gel batteries.

Yes, it is possible to connect external sensors. A Smart Battery Sense, a SmartShunt or a BMV-712 Smart battery monitor can be used to communicate the battery voltage and temperature to one or more Smart IP43 chargers via the VE.Smart Networking network.

Yes, thanks to its VE.Direct interface, this charger can be connected to a GX device such as the Cerbo GX for a wired data connection. This also enables the Instant Readout remote functionality via the VRM portal.

The charger must be permanently mounted using the mounting brackets integrated into the heat sink. It must be installed vertically with the terminals facing downward, on a non-flammable substrate, with at least 10 cm of clearance around it and good natural ventilation. Do not install it directly above the battery or in a sealed compartment with the battery.

The AC connection to the shore power must comply with local electrical regulations. The charger must be plugged into a grounded AC outlet. The AC cable is sold separately and connects via an IEC 320 C14 inlet with a retaining clip.

For the DC connection, use a flexible multistrand copper DC power cable with a sufficient cross-section. Install an inline fuse or appropriately rated circuit breaker as close as possible to the battery. Ensure the DC power cable polarity is correct at all connections. Battery terminals are 16 mm² (AWG6) screw terminals.

After installation, you can configure the charger in two ways:

Via the charger: Press the MODE button to select one of the built-in charge modes (Normal, Normal + Reconditioning, High, High + Reconditioning or Li-ion).Via VictronConnect: Use a Bluetooth-compatible device (phone or tablet) with the VictronConnect app. Connect to the charger, access the battery settings, and choose a built-in preset or set custom parameters.
