Smart IP43 nabíječka 24/16 (1+1)

The Smart IP43 24/16 (1+1) charger delivers a maximum charging current of 16 A for the service battery. It also has a second output limited to approximately 4 A, intended for the starter battery.

This specific model, the Smart IP43 Charger 24/16 (1+1), features two charging outputs:

The first output is dedicated to the service battery and can provide up to 16 A. The second output is for the starter battery and is limited to approximately 4 A.

The Victron Energy Smart IP43 24/16 (1+1) charger delivers a maximum efficiency of 96%. This ensures highly efficient power conversion, minimizing losses.

The Smart IP43 charger is designed to be cooled by natural convection. This means it does not use a fan, making it silent and reducing maintenance requirements.

The Smart IP43 charger offers several adaptive charging modes, which can be selected via the mode button or the VictronConnect app:

Normal Mode: For most lead-acid batteries. Normal Mode + Reconditioning: Includes a reconditioning step for lead-acid batteries. High Mode: For batteries requiring a higher charging voltage. High Mode + Reconditioning: Combines high mode with a reconditioning step. Li-ion Mode: Specifically adapted for lithium-ion batteries (LiFePO₄).

Yes, the Smart IP43 charger can be used as a power supply. The output voltage can be configured using Bluetooth via the VictronConnect app or via the VE.Direct interface.

The Smart IP43 24/16 (1+1) charger accepts a wide AC input voltage range from 85 to 250 VAC. It delivers full power from 100 VAC and starts at 90 VAC. It can also operate with a DC input from 90 to 375 VDC.

The dimensions of the Smart IP43 24/16 (1+1) charger are 180 x 249 x 116 mm (height x width x depth). Its weight is 2.7 kg.

The Smart IP43 charger integrates an adaptive battery management system with a 6-stage charging algorithm for lead-acid batteries:

Bulk (Bulk charge): Fast constant-current charge.
Absorption: Constant-voltage hold for full charge, with variable duration based on previous discharge.
Reconditioning: Optional step to revitalize deeply discharged batteries.
Float (Maintenance): Lower-voltage hold to compensate for self-discharge.
Storage: Reduced float voltage to minimize aging and gassing when the battery is not in use.
Refresh: Periodic voltage increase to absorption level to equalize the battery in storage mode.
For Li-ion batteries, the algorithm is simplified to 3 stages.

The BatterySafe mode is a protective function that prevents damage caused by excessive battery gassing. If a high charging current is combined with a high absorption voltage to charge a battery quickly, the charger will automatically limit the rate of voltage increase once the gassing voltage is reached. This protects the battery from overheating and damage.

The Storage mode is designed to minimize maintenance and premature aging of the battery when it is not used for an extended period (more than 24 hours without discharge). In this mode, the float voltage is reduced to 2.2 V/cell (26.4 V for a 24 V battery) to minimize gassing and corrosion of the positive plates. Once a week, the voltage is raised to the absorption level to equalize the battery, thus preventing electrolyte stratification and sulfation.

For a 24V battery in normal charging mode, the voltages are as follows:

Absorption: 28.8 VFloat (Hold): 27.6 VStorage (Storage): 26.4 V

Yes, the Smart IP43 Charger's charging algorithm is fully programmable. This programming can be done via Bluetooth using the VictronConnect app or via the VE.Direct interface. Three pre-programmed algorithms can also be selected using the mode button on the charger.

The programmable relay (SPDT - 5 A up to 250 VAC / 5 A up to 28 VDC) integrated into the charger can be configured via the VE.Direct interface or a Bluetooth-compatible device. It can be programmed to trigger on an alarm or other specific events, providing flexibility for integration into larger systems.

Yes, the Smart IP43 charger is compatible with Li-ion batteries (LiFePO₄). It has a specific charging mode for these batteries (3 stages instead of 6). Control of the charger's activation/deactivation can be implemented by connecting a relay output or open-collector optocoupler from a Li-ion BMS to the remote on/off port. Full voltage and current monitoring can also be performed via Bluetooth.

Yes, it is possible to connect external voltage and temperature 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 VE.Smart Networking. This improves charge accuracy.

Yes, this specific model (1+1) is designed to charge two battery banks simultaneously. It provides 16 A to the house battery and has a second output limited to approximately 4 A, intended for the starter battery to keep it charged.

Yes, it is possible to synchronize charging by pairing two or more Smart IP43 chargers within a VE.Smart network. This feature improves charging efficiency and extends battery life.

For mounting the Smart IP43 charger, it is recommended to:

Install it on a non-flammable substrate.Ensure at least 10 cm clearance around the charger for proper natural airflow.Mount it vertically with the terminals facing downward.Do not install it directly above or in the same sealed compartment as the battery.Use appropriate pan/flat-head screws through the mounting holes.

The Victron Energy Smart IP43 charger provides IP43 protection for electronic components. The connection area, however, has IP22 protection. This means it is protected against solid objects larger than 1 mm and water splashes (IP43), and against fingers and tilted water droplets (IP22 for the connection area).
