Phoenix Smart IP43 charger 24/25(1+1) 230V

This charger is a (1+1) model, meaning it has two separate outputs:

A main output of 25 A, designed to charge the 24 V service battery. A second output, limited to about 4 A with a slightly lower output voltage, intended to maintain the charge of a starter battery.

The Phoenix Smart IP43 24/25(1+1) 230V charger has an IP43 protection rating for its electronic components, protecting against solid objects larger than 1 mm and water splashes. The connection area, however, has an IP22 protection rating.

This charger is compatible with a wide range of battery types thanks to its 6-stage adaptive charging algorithm. It can efficiently charge batteries:

Flooded lead-acidAGMGelLiFePO₄ (Lithium Iron Phosphate)

Yes, the Phoenix Smart IP43 charger integrates Bluetooth Smart technology. This allows wireless configuration, monitoring, control, and firmware updates via the VictronConnect app on a mobile device.

The adaptive charging algorithm optimizes the charging process based on battery usage. It consists of 6 steps:

Bulk (bulk charge): Charges the battery at constant current until the voltage reaches the absorption level.
Absorption: Maintains constant voltage to complete charging, with duration automatically adjusted according to depth of discharge.
Reconditioning: An optional step to revitalize deeply discharged batteries.
Float (trickle charge): Maintains the battery at a lower voltage to compensate for self-discharge.
Storage: Reduces float voltage after 24 hours of inactivity to minimize aging and stratification.
Refresh: A weekly charge pulse to equalize the battery in storage mode.

Yes, the Phoenix Smart IP43 charger can be used as a power supply. The output voltage can be adjusted via Bluetooth or the VE.Direct interface to meet your specific requirements.

The storage mode activates when the battery has not undergone discharge for 24 hours. In this mode, the float voltage is reduced to 2.2 V/cell (26.4 V for a 24 V battery) to minimize gas release and positive plate corrosion. Once per week, the voltage is returned to the absorption level to "equalize" the battery, preventing electrolyte stratification and sulfation, which are major causes of early battery failure.

The charger automatically compensates for the DC cable voltage drop. It slightly increases the output voltage as DC current rises, ensuring the correct voltage is applied to the battery even with longer or undersized cables.

This charger can operate within a temperature range of -20 to 60 °C. It delivers the nominal output current up to 40 °C, after which power is linearly reduced to 20 % at 60 °C.

The idle power consumption of this charger is very low, only 1W.

The Phoenix Smart IP43 24/25(1+1) 230V charger weighs 2.7 kg and its dimensions are 180 x 249 x 116 mm (height x width x depth).

The BatterySafe mode is designed to prevent damage from excessive gassing. If a high charging current is combined with a high absorption voltage to rapidly charge a battery, the charger automatically limits the rate of voltage increase once the gassing voltage is reached, thereby protecting the battery.

Yes, the charging algorithm is fully programmable. You can configure it using Bluetooth connectivity via the VictronConnect app or via the VE.Direct interface. Three pre-programmed algorithms are also selectable via the mode button on the charger.

Yes, the charger is equipped with a remote on/off function. It consists of two terminals (Remote H and Remote L) to which a switch or relay contact can be connected to control the charger remotely.

The VE.Direct interface enables a wired data connection to a GX device (such as the Cerbo GX), a PC, or other equipment. It also supports instant readout via VictronConnect remotely from VRM (Victron Remote Management), facilitating monitoring and advanced configuration.

The charger must be permanently mounted using the mounting flanges integrated into the heat sink. It is recommended to install it vertically with the terminals facing downward, on a non-flammable substrate. Ensure at least 10 cm of free space around the charger for proper airflow and natural ventilation.

The charger uses an IEC 320 C14 input with a retaining clip for the AC connection. The AC cord is not supplied and must be ordered separately. The connection to the mains must comply with local electrical regulations, and the charger must be plugged into a grounded AC outlet.

Use flexible multistrand tinned copper DC power cables with sufficient cross-section. The charger’s screw terminals accept cables up to 16 mm² (AWG6). It is also essential to install an inline fuse or appropriately rated circuit breaker as close as possible to the battery.

Yes, you can connect external sensors for battery voltage and temperature. A Smart Battery Sense, a SmartShunt, or a BMV-712 Smart battery monitor can be used to communicate this data to one or more Smart IP43 chargers via the VE.Smart Networking. This enables more precise and optimized charging.

Yes, it is possible to pair two or more Smart IP43 chargers within a VE.Smart Network. This feature enables synchronized charging, improving charging efficiency and extending battery life.
