Authorised Victron Energy InstallerVictron part no. PSC242551095
The Victron Phoenix Smart IP43 Charger 24/25 (1+1) is tailored for marine and off-grid users who need reliable charging for both starter and house batteries. Featuring Bluetooth Smart connectivity, users can easily monitor and adjust the charger via the VictronConnect app, providing real-time feedback and remote control.
This charger uses an adaptive 5-stage charging algorithm, including bulk, absorption, recondition, float, and storage modes, which optimise the charging process based on battery use. The charger prevents excessive gassing during high-current charging by using BatterySafe mode, and Storage Mode minimises ageing when the battery is idle.
The Phoenix Smart 1+1 model ensures 25A is delivered to the house battery and 3A to the starter battery, with full control over the charging process via Bluetooth or VE.Direct interface. The charger supports Li-ion (LiFePO₄) batteries and allows the programming of custom charge parameters through the app or interface. A programmable relay allows for custom alerts or events based on specific conditions.
This charger is ideal for boats, off-grid systems, and any application requiring efficient charging of multiple battery banks with full monitoring and control.
Key Features
Features of the Phoenix Smart IP43 Charger 24/25(1+1)
Bluetooth Smart enabled
Any Bluetooth enabled smart phone, tablet or other device can be used to monitor, to change settings and to update the charger when new software features become available.
Adaptive 5-stage charge algorithm: bulk, absorption, recondition, float, storage
The Phoenix Smart IP43 charger features our well-known ‘adaptive’ battery management system that can be pre-set 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
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
Less maintenance and ageing when the battery is not in use: the Storage Mode
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 minimise gassing and corrosion of the positive plates. Once a week the voltage is raised back to the absorption level to ‘equalise’ 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 pre-programmed algorithms can be selected with the mode button on the Phoenix Smart IP43 Charger.
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
You can programme the Phoenix Smart IP43 Charger using the VE.Direct interface or a Bluetooth enabled device to trip on an alarm or other events.
