Victron Phoenix Smart IP43 Charger 24V 25A (3)

Victron Phoenix Smart 24V 25A (3) Charger

With boat owners in mind, this adaptive 5-stage charger can provide either 16A or 25A of charging. The Phoenix 1+1 model delivers 3A to the starter battery, with the remainder going to the house bank. Like all
Smart products from Victron, it is Bluetooth-enabled, allowing you to monitor the charger and set alarms directly from your phone.
Adaptive, intelligent, dynamic charging functions.

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

Phoenix Smart (3): three full power outputs for charging 3 battery banks
Each output can deliver the full rated output current. However, the sum of all 3 output currents must not exceed the
rated current of the charger.

Automatic voltage compensation
The charger compensates for a voltage drop in the DC cables by slightly increasing the output voltage as the DC current increases. Further details on this can be found in the manual.

The right amount of charge: variable constant voltage phase
When the battery is only slightly discharged (e.g., a yacht connected to shore power), a short constant voltage phase is selected to prevent overcharging. After a deep discharge, the
constant voltage phase is automatically extended to ensure that the battery is fully charged.

Less maintenance and aging when the battery is at rest: the storage mode
The storage mode is activated whenever no discharge has occurred within 24 hours. In storage mode, the float voltage is then reduced to 2.2 V/cell (13.2 V for a 24V battery) to
minimize gas generation and corrosion on the positive plates. Once a week, the voltage is increased to the equalization voltage level. This achieves a kind of equalization charge that prevents
electrolyte stratification and sulfation—the two main causes of premature battery failure.

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

Fully programmable charging algorithm
The charging algorithm can be programmed via Bluetooth or the VE.Direct interface. The MODE button allows you to choose between three pre-programmed algorithms.

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