Bluetooth Smart enabled 
Any Bluetooth enabled smart phone, tablet or other devices 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 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 algorithum: 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 absoprtion 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 absoprtion 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 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 2.2V/cell (13.2V for a 12V 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 acheived with Bluetooth. 
 
Fully programmable charge algorithm 
The charge algorithm can be programmed with the help of Bluetooth or the VE.Direct interface. Three preprogrammed algorithms can be selected with the mode button. 
 
Remote on-off
Remote on-off can be implemented with a switch, a relay or with an open collector optocoupler signal. 
 
VE.Direct interface 
For a wired connection to a Colour Control panel, PC or other devices. 
 
Programmable relay
Can be programmed using the VE.Direct interface or a Bluetooth enabled device to trip on an alarm or other events.
