Victron Phoenix Smart IP43 12/50 (1+1) 230V Battery Charger, 5 Year Warranty 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 Phoenix Smart (3): three full current outputs to charge 3 battery banks Each output can supply the full rated output current But the total of the 3 outputs combined can never exceed the current rating of the charger 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 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 (LiFePO) 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 VEDirect interface Three preprogrammed algorithms can be selected with the mode button (see specifications)
