Victron Energy VRLA charger Phoenix Smart 24/16 (2) 24 V Charging current (max.) 16 A

Ready for Bluetooth smart
Changing the settings and updating the charger with new software features can be done with any Bluetooth-enabled smartphone, tablet or other device.

Phoenix Smart (1+1): Two outputs for charging two battery banks
The second output is intended for charging the starter battery. As a result, it is limited to 3 A and has a slightly lower output voltage for maintaining the charge of the normally full starter battery.

Phoenix Smart (13): Three full current outputs for charging 3 battery banks
Each output can supply the full rated output current. However, all 3 output currents together must not exceed the rated current of the charger.

Automatic voltage compensation
The charger compensates for a voltage drop across the DC cables by slightly increasing the output voltage as the DC current increases. See the manual for details.

Adaptive five-stage charging algorithm: Constant current (“bulk”) phase, constant voltage (“absorption”) phase, recovery (“recondition”) phase, charge retention (“float”) phase, storage voltage (“storage”) phase
The Phoenix Smart charger has our well-known "adaptive" battery management system, which can be adapted to the different battery types. "Adaptive" means that the charging characteristic is automatically adapted to the type of battery use.

The correct load quantity: variable constant voltage phase
In case of low battery discharge (e.g. a yacht connected to shore current), a short constant voltage phase is selected to avoid overcharging. After a deep discharge, the constant voltage phase is automatically extended to ensure that the battery is fully charged.

Preventing damage from excessive gassing: The BatterySafe mode (see Figure 2)
In order to shorten the charging time, a maximum charging current was selected together with a high constant voltage. However, in order to avoid excessive gas development toward the end of the constant current phase, the charger limits the speed of the voltage rise after the gassing voltage has been reached.

Less maintenance and aging when the battery is idle: The storage mode
The storage mode is activated whenever no discharge has taken place within 24 hours. In storage mode, the charge retention voltage is then reduced to 2.2 V/cell (13.2 V for a 24 V battery) to minimize gas development and corrosion on the positive plates. Once a week, the voltage is increased to the level of the gassing voltage. This results in a kind of equalizing charge that prevents electrolyte stratification and sulphation - the two main causes of premature battery failure.

Also charges lithium-ion (LiFePO₄) batteries
An on/off control can be attached by connecting a relay or an optocoupler output with open collector from a Li-Ion BMS to the remote controlled on/off port. Alternatively, voltage and current can also be controlled completely via Bluetooth.

Fully programmable loading algorithm
The charging algorithm can be programd via Bluetooth or via the VE.Direct interface. With the MODE key, you can select between three pre-programd algorithms.

Remote on/off
The remote on/off consists of two terminals: Remote H and Remote L. A remote on/off switch or relay contact can be connected between H and L. Alternatively, the H terminal can be raised or the L terminal can be pulled down.

VE.Direct interface
For a wired data connection to a Color Control panel, a PC or other devices. See the VictronConnect app on the Victron Energy website.

Programmable relay
Can be programd through the VE.Direct interface or a Bluetooth enabled device to trigger an alarm or other events.
