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 charging. The Phoenix 1+1 model supplies 3A to the starter battery, with the rest going to the house bank. Bluetooth enabled like all
Victron Smart products, you can 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 trickle charging the typically full starter battery.

Phoenix Smart (3): three full current outputs for charging 3 battery banks
Each output can deliver 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 in the DC cables by slightly increasing the output voltage as the DC current increases. Further details can be found in the manual.

The right amount of charge: variable constant voltage phase
For low battery discharge (e.g., a yacht connected to shore power), a short constant voltage phase is chosen to avoid overcharging. After a deep discharge, the
constant voltage phase is automatically extended to ensure the battery is fully charged.

Less maintenance and aging during battery inactivity: Storage mode
Storage mode is activated whenever there has been no discharge within 24 hours. In storage mode, the float voltage is then reduced to 2.2 V/cell (13.2 V for a 24 V battery) to
minimize gassing and corrosion of the positive plates. Once a week, the voltage is increased to the gassing voltage level. This achieves a form of equalization charge, which 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 optocoupler output with an open collector from a Li-ion BMS to the remote on/off port.
Alternatively, voltage and current can also be fully regulated via Bluetooth.

Fully programmable charging algorithm
The charging algorithm can be programmed via Bluetooth or the VE.Direct interface. The MODE button can be used to select 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.
