Phoenix smart IP43 chargers:

With boat owners in mind this adaptive 5-step charger can provide either 30A or 50A of charge to each of three battery banks. Or the Phoenix 1+1 model provides 3A to the starter-battery, the rest to the ‘house’ bank. 24V models are available with 16A/25A charge. Bluetooth enabled, you can monitor the charger and set alarms straight from your phone. Adaptive, intelligent, dynamic charge features – see the datasheet below. 

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.

Phoenix Smart (1+1): two outputs to charge 2 battery banks 

The second output, limited to approximately 3A and with a slightly lower output voltage, is intended to top up a starter battery. 

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 5-stage charge algorithm: bulk – absorption – recondition – float – storage 

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 

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 

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 ‘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). 

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. Learn more about batteries and battery
