Product Overview

The Victron Energy Phoenix Smart IP43 12/30(3) (PSC123053095) is a professional-grade, Bluetooth-enabled three-bank 12V battery charger delivering up to 30 amps of total output across three independent charge outputs each capable of supplying the full rated current, with the combined total capped at 30 amps. The 30A rating positions it as the mid-range option in the Phoenix Smart 12V lineup more capable than a single-bank charger for multi-bank systems, and appropriately sized for vessels and installations where 50A would overspecify the system or exceed available AC circuit capacity.

The (3) configuration is built for the real-world architecture of multi-bank marine and vehicle electrical systems start, house, and thruster banks each receiving independent, adaptive managed charging from a single shore power connection. The 6-stage adaptive algorithm covers the full charge and maintenance lifecycle, with BatterySafe mode providing gassing protection at higher charge currents. Built-in Bluetooth for VictronConnect monitoring and configuration, VE.Direct for Cerbo GX integration, a programmable relay, and BMS remote on/off control for lithium battery systems make this a complete professional charger platform in a mid-range output package.

Features & Benefits

• Three Independent Full-Current Outputs at 30A Total — Each of the three outputs can supply up to the full 30A rated current, with the combined total capped at 30A. Current distributes dynamically based on each bank's demand — a discharged house bank draws the majority while topped-up start and thruster banks draw little. The 30A total is appropriate for mid-sized multi-bank systems: three banks of 100–200Ah each charging concurrently within a practical shore power window.
• Mid-Range Output — Correctly Sized for Smaller Multi-Bank Systems — At 30A, this is the right charger for vessels, motorhomes, and installations where three battery banks each require managed charging but a 50A unit would exceed available AC circuit capacity or overspecify the battery bank sizes. Matching charger output to bank capacity is as important as having the correct number of outputs.
• Adaptive 6-Stage Charge Algorithm — Bulk delivers maximum current for rapid recharge. Absorption holds at the correct voltage while current tapers — adaptive to discharge depth, shortening for shallow discharges and extending for deep ones. Recondition recovers sulphated lead acid batteries from repeated partial charging. Float safely maintains a fully charged battery. Storage Mode activates after 24 hours without discharge, reducing float voltage to 2.2V/cell to minimise gassing and plate corrosion during layup — with a weekly equalisation pulse to prevent stratification and sulphation. Refresh periodically returns the battery to full charge from Storage Mode to prevent capacity drift. Six stages managing the complete battery lifecycle on shore power.
• BatterySafe Mode — Limits the rate of voltage rise when high charge current and high absorption voltage are combined, once the battery approaches its gassing voltage. Prevents plate damage and electrolyte loss that excessive gassing causes, without halting the charge cycle. Confirmed in this brief.
• Variable Absorption Time — Absorption duration adjusts automatically to discharge depth. Shallow discharges receive short absorption to prevent overcharge; deep discharges receive extended absorption for complete recovery. No manual adjustment required.
• Storage Mode — Battery Health During Layup — Float voltage drops to 2.2V/cell (13.2V for 12V batteries) after 24 hours without discharge, minimising electrolyte gassing and positive plate corrosion. Weekly absorption-level equalisation prevents stratification and sulphation across extended shore power periods — critical for seasonal vessels and vehicles between use periods.
• LiFePO₄ Lithium Battery Support — Selectable 3-stage lithium charge profile via Bluetooth or VE.Direct. BMS charge/discharge control via remote on/off H/L terminals — connect the BMS relay or open-collector output to halt charging when required. Full voltage and current control also achievable via Bluetooth.
• Built-In Bluetooth — VictronConnect App — Monitor real-time charge status, configure battery profiles and algorithms, set alarms, and update firmware wirelessly from any iOS or Android device. No additional hardware required for direct charger access.
• VE.Direct Interface — Wired connection to Victron Cerbo GX, Colour Control GX, or PC for full system integration and VRM remote monitoring portal access.
• Remote On/Off — H/L Terminal — External charger control via remote switch, relay, or open-collector optocoupler. Terminal H pulled high or Terminal L pulled low. Supports BMS charge management and panel-mounted switch control.
• Programmable Relay — User-configurable to activate on alarm, charge complete, temperature event, or other defined conditions via VE.Direct or Bluetooth. Active only while connected to AC power.
• Automatic Voltage Compensation — Proportionally increases output voltage with DC current to compensate for resistive voltage drop across DC cable runs. Ensures correct charge voltage at the battery terminals regardless of installation cable length.
• Wide 120–240V AC Input — Accepts both Australian 240V and North American 120V shore power automatically. Suitable for vessels and vehicles operating internationally.
• IP43 Rated — Protected against solid objects greater than 1mm and water spray up to 60° from vertical. Suitable for marine engine rooms and protected enclosed battery compartments with incidental moisture exposure.

Frequently Asked Questions

How does the 12/30(3) differ from the 12/50(3) and which should I choose?

Both provide three independent full-current outputs. The 30A total is appropriate for mid-sized banks — three banks of approximately 100–150Ah — where 30A provides a practical charge rate without overspecifying. The 50A model is correct for larger banks of 200Ah and above on each output, or where faster charge recovery within a shore power window is required. Match charger output to approximately 10–20% of your primary bank's Ah capacity for optimal lead acid charging.

Can each of the three outputs supply the full 30A simultaneously?

Each output is capable of supplying the full rated 30A, but the combined total across all three outputs can never exceed 30A. If all three banks are in bulk charge simultaneously, the 30A is shared based on each bank's current demand — a deeply discharged bank draws more, a nearly full bank draws less.

What is BatterySafe mode and is it relevant at 30A?

BatterySafe automatically limits the rate of voltage rise when a high charge current and high absorption voltage are combined, preventing excessive gassing at the battery's gassing voltage threshold. At 30A with an elevated absorption setpoint — a configuration used to accelerate charging — BatterySafe prevents plate damage and electrolyte loss that aggressive charging would otherwise cause.

Can I use this charger with a lithium house bank and lead acid start and thruster banks?

The charger supports LiFePO₄ profiles configurable via Bluetooth, with BMS remote on/off control. However, simultaneously applying a lithium charge profile on one output and a lead acid profile on another across the same charger may have limitations depending on how the charger manages per-output algorithm selection. Confirm per-output algorithm independence from the Victron datasheet before specifying for mixed chemistry multi-bank applications.

Does this charger integrate with a Victron Cerbo GX for system-level monitoring?

Yes. The VE.Direct interface enables wired connection to a Cerbo GX, providing full system integration and access to the Victron VRM remote monitoring portal. Bluetooth provides direct local monitoring and configuration from a smartphone without requiring a GX device.
