Victron Energy PSC241651095 Phoenix Smart IP43 Charger 24/16(1+1) 120-240V

Victron Energy Phoenix Smart IP43 24/16(1+1) Smart Dual-Bank 24V Charging at 16A. Right-Sized for Smaller Vessels and Systems.

---

Product Overview

The Victron Energy Phoenix Smart IP43 24/16(1+1) (PSC241651095) is a professional-grade, Bluetooth-enabled dual-output 24V battery charger rated at 16 amps, designed for dual-battery installations where a 25A charger is more capacity than the system requires. The (1+1) configuration delivers the full 16A rated output to the primary house or service battery bank through a complete adaptive charge cycle, while a dedicated secondary output maintains a starter battery at a low, safe maintenance current all from a single shore power connection.

At 16A, the PSC241651095 is the right-sized option for smaller vessels, compact motorhomes, caravans, and off-grid systems where bank capacity, available AC circuit current, or installation space make a 25A unit unnecessary or impractical. It carries the same professional feature set as its 25A sibling 6-stage adaptive charging, Bluetooth via VictronConnect, VE.Direct integration with Cerbo GX, BMS remote on/off control for lithium batteries, programmable relay, and Storage Mode in a unit sized for systems that don't need maximum output current.

Features & Benefits

• Right-Sized 16A Output for Smaller Systems — The 16A rating makes the PSC241651095 the appropriate choice where a 25A charger would be overspecified — smaller vessel battery banks (under 200Ah), compact caravans and motorhomes, off-grid cabins with modest battery capacity, and installations where the available AC shore power circuit is limited. Matching charger output to battery bank size reduces charge time without overspecifying hardware or drawing unnecessary AC current.
• (1+1) Dual-Output — Full Charge to House Bank, Maintenance to Starter — The primary output delivers the full 16A rated current to the house or service battery through a complete 6-stage adaptive charge cycle. The secondary output maintains the starter battery at a low maintenance current — keeping it ready without consuming primary bank current or risking overcharge from excessive current application. Correct for the asymmetric needs of a start/house battery system.
• Adaptive 6-Stage Charge Algorithm — Six managed stages covering the complete charge and maintenance lifecycle. Bulk delivers maximum current for rapid recharge. Absorption holds at the correct voltage while current tapers — with adaptive absorption time that shortens for shallow discharges and extends for deep discharges. Recondition recovers sulphated lead acid batteries. Float safely maintains a fully charged battery. Storage Mode activates after 24 hours without discharge, reducing float voltage to minimise gassing and plate corrosion during layup, with a weekly equalisation pulse to prevent stratification and sulphation. Confirm the 6th stage from the datasheet.
• Storage Mode — Protects During Layup — Activates automatically when the battery has not been discharged for 24 hours. Float voltage drops to 2.2V/cell to minimise electrolyte gassing and positive plate corrosion during extended shore power connection without use. A weekly absorption-level pulse equalises the battery, preventing stratification and sulphation — the primary causes of premature lead acid battery failure in seasonally used vessels and vehicles.
• LiFePO₄ Lithium Battery Support — LiFePO₄ profiles are configurable via Bluetooth or VE.Direct, with a 3-stage algorithm for lithium operation. BMS charge/discharge control is implemented via the remote on/off port — the BMS relay or open-collector output connects to the remote terminals, allowing the BMS 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, set alarms, and update firmware wirelessly from any iOS or Android device. Direct Bluetooth access without additional hardware or wiring.
• VE.Direct Interface — Cerbo GX Integration — Wired VE.Direct connection enables full integration with a Victron Cerbo GX for system-level monitoring via the VRM portal or local GX display. Also supports wired connection to a PC for configuration and logging.
• Remote On/Off — BMS and External Control — The remote on/off input accepts a switch, relay contact, or open-collector optocoupler signal, enabling BMS control of the charger in lithium battery installations, or panel switch control in systems where operator-controlled charging is required.
• Programmable Relay — The onboard relay is configurable to activate on a user-defined event — alarm, charge complete, temperature trigger, or other condition — via VE.Direct or Bluetooth. Active only while the charger is connected to AC power.
• Automatic Voltage Compensation — Slightly increases output voltage in proportion to DC output current to compensate for resistive drop over long cable runs between charger and battery. Ensures the battery receives the correct charge voltage regardless of installation cable length.
• Wide 120–240V AC Input — Accepts both Australian 240V and North American 120V shore power without manual voltage switching. Suitable for vessels and vehicles used across international destinations.
• IP43 Rated — Protected against solid objects greater than 1mm and water spray up to 60° from vertical. Suitable for marine engine rooms and enclosed battery compartments with incidental moisture exposure.

Frequently Asked Questions

When should I choose the 16A model over the 25A version?

The 16A model is appropriate when your primary battery bank is smaller — typically under 200Ah — where a 25A charger would reach absorption voltage too quickly for optimal charging, or where your available AC shore power circuit is limited. As a general guide, a charger rated at 10–20% of battery bank capacity in Ah delivers the most effective charge profile for lead acid batteries.

What is the difference between this (1+1) model and the (3) configuration?

The (1+1) provides a full-current primary output for the house bank and a low-current secondary output for a starter battery. The (3) provides three outputs each capable of supplying the full rated current, with the combined total capped at the charger's rating — suited to three similarly sized banks each needing significant current. Choose (1+1) for a house-plus-starter setup; choose (3) for three active battery banks.

Can this charger be integrated with a Victron Cerbo GX for remote monitoring?

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

Can a lithium BMS control when this charger operates?

Yes. Connect the BMS relay or open-collector output to the remote on/off terminals. The BMS can then enable or disable the charger based on battery state — stopping charging when the battery is full or a protection event occurs. Full charge voltage and current adjustment is also available via Bluetooth for more advanced BMS integration scenarios.

Is Storage Mode suitable for seasonal layup of a vessel or vehicle?

Yes — Storage Mode is specifically designed for this use case. After 24 hours without a discharge event, the charger reduces float voltage to 2.2V/cell to minimise electrolyte gassing and plate corrosion during extended periods at shore power. A weekly equalisation pulse prevents electrolyte stratification and sulphation — the primary causes of lead acid battery failure during seasonal storage.
