Victron Energy PSC242553095 Phoenix Smart IP43 Charger 24/25(3) 120-240V
Victron Energy Phoenix Smart IP43 24/25(3) Three Banks. Six Charge Stages. One Intelligent Charger.
Product Overview
The Victron Energy Phoenix Smart IP43 24/25(3) (PSC242553095) is a professional-grade, Bluetooth-enabled multi-bank battery charger delivering up to 25 amps across three independent 24V output channels each capable of supplying the full rated current, with the total combined output capped at the charger's rated capacity. Designed with marine applications firmly in mind, the three-output (3) variant is built for vessels and installations running separate battery banks engine start, house, and bow thruster, for example where each bank requires independent, correctly managed charging from a single shore power connection.
The Phoenix Smart IP43 is not a basic mains charger. It runs a fully adaptive 6-stage charge algorithm Bulk, Absorption, Recondition, Float, Storage, and Refresh that adjusts in real time to how each battery is actually being used. Shallow-discharge cycles receive shortened absorption to prevent overcharge; deep discharges trigger extended absorption for complete recovery. Storage Mode activates automatically after 24 hours without discharge, reducing float voltage to minimise gassing and plate corrosion, with a weekly equalisation pulse to prevent stratification and sulphation. The result is a charger that actively maintains battery health across extended layup periods not just during active charging cycles.
Bluetooth connectivity via the VictronConnect app provides full monitoring, alarm configuration, and charge algorithm programming from a smartphone. VE.Smart Network support enables synchronised charging across multiple paired Phoenix Smart chargers improving charge efficiency and battery longevity in larger multi-charger installations. The IP43 rating provides protection in marine engine rooms and enclosed battery compartments, and the wide 120–240V AC input accommodates both Australian shore power and international marina supplies.

Features & Benefits
- Three Independent Full-Current Outputs — (3) Configuration — Each of the three output channels can supply up to the full 25A rated current independently, with the combined total across all three outputs capped at 25A. This allows the charger to prioritise current to whichever bank needs it most — a deeply discharged house bank will draw the bulk of available current while topped-up start and thruster banks draw little — without manual management or current balancing by the user.
- Adaptive 6-Stage Charge Algorithm — Six stages, not the standard three, covering the full charge and maintenance lifecycle of a battery bank. Bulk and Absorption handle active recharging. Recondition recovers heavily sulphated lead acid batteries. Float maintains a full battery safely. Storage Mode reduces voltage after 24 hours of inactivity to minimise gassing and corrosion during layup — with an automatic weekly equalisation pulse to prevent stratification. Refresh brings the battery back to full charge from Storage mode. This is comprehensive long-term battery care, not just a charge cycle.
- Variable Absorption Time — Adaptive to Discharge Depth — The absorption stage duration adjusts automatically based on how deeply the battery was discharged. A yacht on shore power with shallow daily discharges gets short absorption to prevent overcharge. A battery recovered from deep discharge after a crossing gets extended absorption to ensure it reaches 100% state of charge. The charger makes this decision without manual intervention.
- Storage Mode — Protects Batteries During Layup — Activates automatically when a battery has not been discharged for 24 hours. Float voltage drops to 2.2V/cell (13.2V equivalent for a 12V bank — scaled for 24V) to minimise electrolyte gassing and positive plate corrosion during extended periods at shore power. A weekly absorption-voltage equalisation pulse prevents electrolyte stratification and sulphation — the two leading causes of premature lead acid battery failure during storage.
- LiFePO₄ Lithium Battery Support — Compatible with lithium iron phosphate batteries. BMS charge/discharge control is implemented via the remote on/off port — connecting a relay or open-collector optocoupler output from the BMS to the H/L terminals enables the BMS to stop charging when required. Full voltage and current control is also achievable via Bluetooth for installations requiring software-managed lithium charging.
- Automatic Voltage Compensation — Monitors DC output current and slightly increases output voltage to compensate for the resistive voltage drop across long battery cable runs. Ensures the battery receives the correct charge voltage regardless of cable length — important in marine installations where battery banks may be located far from the charger.
- Built-In Bluetooth — VictronConnect App — Monitor charge status, configure charge algorithms, set battery type profiles, configure alarms, and update firmware wirelessly via any iOS or Android device. No wired connection to a display or GX device required for basic monitoring and configuration.
- VE.Smart Network — Synchronised Charging — Pair two or more Phoenix Smart IP43 chargers in a VE.Smart Network to synchronise their charge stages across the network. All chargers in the network transition between Bulk, Absorption, and Float simultaneously — preventing a situation where one charger's float output conflicts with another's absorption-stage current demand. Improves charge efficiency and reduces thermal stress on batteries in multi-charger installations.
- Programmable Relay — An onboard relay can be configured to activate on a user-defined event — charge complete, alarm condition, temperature threshold, or other trigger — via VE.Direct or Bluetooth. Enables integration with external alert systems, generator start/stop circuits, or load management relays.
- Remote On/Off — H/L Terminal — Provides external control of charger operation via a remote switch, relay contact, or open-collector optocoupler. Terminal H can be pulled high or Terminal L pulled low for flexible integration with BMS systems, panel switches, or automation controllers.
- Wide 120–240V AC Input — Accepts both 120V (North American) and 240V (Australian) shore power without manual voltage selection — essential for vessels cruising internationally or moving between Australian marinas and overseas ports.
- IP43 Protection — Protected against solid objects greater than 1mm and water spray up to 60° from vertical. Suitable for marine engine rooms, protected bilge spaces, and enclosed battery compartment installations where some moisture exposure is possible but direct water contact is managed by the installation environment.
- Three Pre-Programmed Algorithms via Mode Button — Three factory battery profiles are selectable directly on the charger without Bluetooth or VE.Direct — useful for initial configuration in the field before a smartphone is connected.

Frequently Asked Questions
What is the difference between the (3) and (1+1) configuration of the Phoenix Smart IP43?
The (3) configuration — this model — provides three independent outputs each capable of supplying the full rated current, with the combined total capped at 25A. It is designed for three similarly sized battery banks. The (1+1) configuration provides two outputs: one full-current output for the house bank and a second limited to approximately 4A at a slightly lower voltage, designed specifically for topping up a starter battery. Choose (3) when all three banks need independent full-current charging; choose (1+1) when one bank is a dedicated starter battery requiring only maintenance charging.
How does the 6-stage charge algorithm differ from a standard 3-stage charger?
A standard 3-stage charger delivers Bulk, Absorption, and Float. The Phoenix Smart IP43 adds Recondition (recovers sulphated lead acid batteries), Storage Mode (reduces voltage after 24 hours inactivity to minimise corrosion and gassing), and Refresh (weekly equalisation pulse in Storage Mode to prevent stratification). These additional stages protect battery health during extended shore power periods and layup — particularly important for marine seasonal storage.
Can this charger be used with lithium LiFePO₄ batteries?
Yes. LiFePO₄ battery profiles are configurable via the VictronConnect app or VE.Direct. BMS charge control is implemented by connecting the BMS relay or optocoupler output to the H/L remote on/off terminals — allowing the BMS to disable the charger when the battery reaches full charge or a protection event occurs. Full charge current and voltage control is also achievable via Bluetooth.
What does VE.Smart Network synchronised charging mean in practice?
When two or more Phoenix Smart IP43 chargers are paired in a VE.Smart Network, they synchronise their charge stage transitions — all units move from Bulk to Absorption, and from Absorption to Float, simultaneously. This prevents one charger's absorption-stage current output from conflicting with another charger already in float, which can cause thermal and electrical stress on the battery. The result is more efficient charging and less wear on both the batteries and the chargers.
Is this charger suitable for Australian shore power and international marina use?
Yes. The 120–240V AC wide-input design accepts both Australian 240V shore power and North American 120V marina supplies without manual voltage switching — an important practical feature for vessels cruising internationally or moving between Australian and overseas ports.
