Ready for Bluetooth Smart Changing the settings and updating the charger with new software features can be done using any Bluetooth-enabled smartphone, tablet or other device.
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 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.
Adaptive five-stage charging algorithm: constant current (“bulk”) phase, constant voltage (“absorption”) phase, recovery (“recondition”) phase, charge maintenance voltage (“float”) phase, storage voltage (“storage”) phase The Phoenix Smart Charger features our well-known "adaptive" battery management system, which can be adapted to different battery types. "Adaptive" means that the charging curve is automatically adjusted to the type of battery use.
The right amount of charge: variable constant voltage phase When the battery discharge is small (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.
Preventing damage from excessive gassing: BatterySafe mode To shorten the charging time, the highest possible charging current was selected together with a high constant voltage. However, to avoid excessive gassing towards the end of the constant current phase, the charger limits the rate of voltage increase after the gassing voltage has been reached. (See charging curve between 14.4 V and 15.0 V in Figure 2.)
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 charge 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 level of the gassing voltage. This creates a type of equalization charge that 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 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 be fully 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 (see technical specifications).
Remote On/Off The Remote On/Off consists of two terminals: Remote H and Remote L. Between H and L a remote on/off switch or relay contact can be connected. Alternatively, terminal H can be pulled up, or terminal L can be pulled down. See manual for details.
VE.Direct interface For a wired data connection to a Color Control panel, PC or other devices. See the VictronConnect app under Downloads/Software on our website.
Programmable relay Can be programmed via the VE.Direct interface or a Bluetooth-enabled device to trigger an alarm or other events.
