Tark IP43 laadija 24/25 (1+1)

The Victron Energy Smart IP43 Charger 24/25 (1+1) is a 24V, 25A smart charger designed to charge two separate battery banks. It features Bluetooth Smart technology for easy monitoring and configuration via the VictronConnect app. Its 6-stage adaptive charging algorithm is optimized for various battery types, including Li-ion. It delivers high efficiency (up to 96%) and includes built-in protections against reverse polarity, short circuits, and overheating.

The designation "(1+1)" indicates that the charger has two separate outputs for charging two battery banks. The main output can supply the full rated current of 25 A, while the second output is limited to approximately 4 A and is intended for maintaining a starter battery or a small auxiliary battery.

Yes, the Victron Smart IP43 charger features a 6-stage adaptive charging algorithm that can be pre-set to suit different battery types, including flooded lead-acid, AGM, Gel, and LiFePO₄. For Li-ion batteries (LiFePO₄), a specific 3-stage algorithm is used.

The Victron Energy Smart IP43 Charger 24/25 (1+1) has a maximum efficiency of 96%. This high efficiency ensures minimal energy consumption and optimized operation.

Yes, the Victron Smart IP43 charger includes multiple protections. It is protected against:

Battery polarity reversal (via a user-inaccessible fuse).Output short circuits.Overheating.

The charger can operate within a temperature range from -20 °C to 60 °C. It delivers the nominal output current up to 40 °C, then the current is linearly derated to 20% at 60 °C to ensure the safety and durability of the device.

Yes, the Victron Smart IP43 charger can be used as a power supply. The output voltage can be configured via Bluetooth or the VE.Direct interface to match the specific needs of your system.

The energy consumption of the Victron Smart IP43 charger in no-load (idle) mode is very low, only 1 W. This helps minimize the overall energy consumption of your installation.

The charger must be mounted vertically, with the terminals facing downward, on a non-flammable substrate. Ensure at least 10 cm of free space around the charger to allow for natural ventilation and prevent overheating. Do not install it directly above the battery or in a sealed compartment with the battery, as batteries can emit explosive gases.

For DC connection, it is recommended to use a flexible multistrand copper DC power cable with sufficient cross-section. An inline fuse or appropriately rated circuit breaker must be installed as close as possible to the battery. Ensure the DC cable polarity is correct at all connections.

The Victron Smart IP43 Charger 24/25 (1+1) has an IP43 protection category for its electronic components. The connection area, however, has an IP22 protection category.

Yes, the AC power cable is not included with the charger and must be ordered separately. The charger is equipped with an IEC 320 C14 input with a retention clip for the AC connection.

Yes, the charger is compatible with Li-ion batteries (LiFePO₄). It features a 3-stage specific charging algorithm for these batteries. Additionally, the charger can be controlled (on/off) by connecting it to a relay output or open-collector optocoupler from a Li-ion BMS via the remote on/off port.

Yes, you can monitor the charger remotely in several ways:

Via Bluetooth Smart and the VictronConnect app on your smartphone or tablet. Via the VE.Direct interface for a wired connection to a GX device (such as the Cerbo GX), enabling instant remote reading via the Victron VRM portal.

Yes, the charger supports external voltage and temperature sensing via Bluetooth. You can use a Smart Battery Sense, a SmartShunt, or a BMV-712 Smart Battery Monitor to send this data to one or more Smart IP43 chargers over the VE.Smart Networking network. This enables automatic voltage compensation and more accurate charging.

Yes, it is possible to synchronize the charging of two or more Smart IP43 chargers by connecting them within a VE.Smart Network. This feature improves charging efficiency and extends battery life.

Yes, the charger can be controlled by a Li-ion BMS. The on/off control of the charger can be implemented by connecting a relay output or open-collector optocoupler from a Li-ion BMS to the remote on/off port of the charger. Full voltage and current control can also be achieved via Bluetooth.

The charger's 6-stage adaptive charging algorithm (bulk, absorption, reconditioning, float, storage, refresh) automatically optimizes the charging process based on battery usage. For example, after a shallow discharge, the absorption time is short to avoid overcharging, while after a deep discharge it is automatically increased to ensure a full charge.

BatterySafe mode is a feature that prevents damage caused by excessive gas release from batteries. If a high charging current is combined with a high absorption voltage, the charger automatically limits the rate of voltage increase once the gassing voltage is reached, thereby protecting the battery.

Storage mode activates when the battery has not been discharged for 24 hours. In this mode, the float voltage is reduced to minimize gassing and corrosion of the positive plates. Once per week, the voltage is raised to the absorption level to "equalize" the battery, preventing electrolyte stratification and sulfation—major causes of premature battery failure.
