Victron Phoenix Smart IP43 Charger 24V 25A (1+1)

Victron Phoenix Smart 24V 25A (1+1) Charger

With boat owners in mind, this adaptive 5-stage charger can provide either 30A or 50A of charging. The Phoenix 1+1 model supplies 3A to the starter battery, the rest to the house bank. Bluetooth enabled like all
Smart products from Victron allow you to monitor the charger and set alarms directly from your mobile 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 to maintain the charge of the starter battery, which is usually full.

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

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

The right amount of charge: variable constant voltage phase
If the battery discharge is low (e.g. a yacht connected to shore power), 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.

Less maintenance and aging when the battery is idle: storage mode
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 24 V battery) to
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 creates a kind of equalizing charge that
Electrolyte stratification and sulfation - the two main causes of premature battery failure - are prevented.

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