Phoenix Smart IP43 Charger 24/25 - 3 Outputs

Please note: Required power cord not included, you can also select them on this page

Bluetooth Smart built-in
The wireless solution to set-up, monitor, update and synchronise Phoenix Smart IP43 Chargers.

Phoenix Smart (1+1): two outputs to charge 2 battery banks
The second output, limited to approximately 4A and with a slightly lower output voltage, is intended to top up a starter battery.

Phoenix Smart (3): three full current outputs to charge 3 battery banks
Each output can supply the full rated output current. But the total of the 3 outputs combined can never exceed the current rating of the charger.

Automatic voltage compensation
The charger compensates for voltage drop over the DC cabling by slightly increasing output voltage when the DC current increases. Please see the manual for details.

Adaptive 6-stage charge algorithm: bulk– absorption – recondition – float – storage – refresh
The Phoenix Smart Charger features our well-known ‘adaptive’ battery management system that can be preset to suit different types of batteries. The ‘adaptive’ feature will automatically optimise the charge process relative to the way the battery is being used.

The right amount of charge: variable absorption time
When only shallow discharges occur (a yacht connected to shore power for example) the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery will be fully charged.

Preventing damage due to excessive gassing: the BatterySafe mode (see fig. 2)
If, in order to quickly charge a battery, a high charge current in combination with a high absorption voltage has been chosen, the charger will prevent damage due to excessive gassing by automatically limiting the rate of voltage increase once the gassing voltage has been reached (see the charge curve between 14,4 V and 15,0 V in fig. 2).

Less maintenance and aging when the battery is not in use: the Storage Mode (see fig. 1 & 2)
The Storage Mode kicks in whenever the battery has not been subjected to discharge during 24 hours. In the Storage Mode float voltage is reduced to 2,2 V/cell (13,2 V for a 12 V battery) to minimize gassing and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to ‘equalize’ the battery. This feature prevents stratification of the electrolyte and sulphation, a major cause of early battery failure.

Also charges Li-ion (LiFePO4) batteries
Charger on-off control can be implemented by connecting a relay or open collector optocoupler output from a Li-ion BMS to the remote on-off port.
Alternatively full control of voltage and current can be achieved with Bluetooth.

Fully programmable charge algorithm
The charge algorithm can be programmed with help of Bluetooth or the VE.Direct interface. Three preprogrammed algorithms can be selected with the mode button (see specifications).

Optional external battery voltage and temperature sensing via Bluetooth
A Smart Battery Sense or a BMV-712 Smart Battery Monitor can be used to communicate battery voltage and temperature to one or more Phoenix Smart IP43 Chargers.

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, terminal H can be pulled high, or terminal L can be pulled low. See manual for details.

VE.Direct interface
For a wired data connection to a Color Control panel, PC or other devices. Please see the VictronConnect app under Downloads / Software on our website.

Programmable relay
Can be programmed using the VE.Direct interface or a Bluetooth enabled device to trip on an alarm or other events.

Synchronized charging
Pairing two or more Phoenix Smart IP43 Chargers in a VE.Smart Network, enables synchronised charging. This improves the charge efficiency and battery life.

What does a Victron smart charger do?

The Victron Blue Smart Charger series consists of intelligent multi-stage battery chargers designed to optimize each charging cycle and maintain charging over long periods. The battery is charged at the maximum current until the voltage reaches the set absorption voltage.

Why do I need a smart charger?

A smart charger avoids electricity peaks and schedules charging to utilize abundant renewable energy, such as sunlight, or when wind energy is plentiful and demand is low.
