Designed for boat owners who demand reliability, the Victron Phoenix Smart IP43 Charger 24/25 (1+1) 120-240VAC is a versatile, marine-grade multi-bank charger that adapts to how you use your batteries. With IP43 protection, it’s built to withstand the harsh conditions of life on board while delivering smart, efficient charging for your delicate electronics and life-supporting batteries. This model requires a 5-15P mains cord and supports 120-240VAC input, with 24V configurations available at 16A or 25A charging per bank.
Smart, flexible charging you can monitor from your phone
Bluetooth Smart built-in gives you wireless setup, monitoring, updates, and alarm notifications directly from your phone. No guesswork—just clear control wherever you are on the boat.
Two powerful configurations to fit your setup
-
Phoenix Smart (1+1) provides two outputs to charge two battery banks. The second output is limited to about 4A and uses a slightly lower output voltage to top up the starter battery without overcharging it.
-
Phoenix Smart (3) delivers three full-current outputs to charge three battery banks, with the total current never exceeding the charger’s rated capacity.
Adaptive, safe, and battery-friendly charging
-
Automatic voltage compensation: compensates for voltage drop over DC cabling by boosting output voltage as current increases, ensuring consistent charging performance.
-
Adaptive 6-stage charge algorithm: bulk → absorption → recondition → float → storage → refresh. The adaptive system presets to suit different battery types and usage patterns, optimizing performance and longevity.
-
Right charge, right time: variable absorption time means shallow discharges keep absorption short to prevent overcharging, while deep discharges trigger longer absorption to achieve a full, safe charge.
-
BatterySafe mode: if a fast-charge scenario with high absorption voltage is chosen, the charger automatically limits voltage ramp-up to prevent excessive gassing and battery damage.
-
Storage Mode: after 24 hours of no discharge, float voltage drops to minimize gassing and corrosion. Once a week, the charger raises voltage back to absorption level to equalize and prevent electrolyte stratification and sulfation.
Li‑ion and flexible control
The Phoenix Smart IP43 can charge Li-ion (LiFePO4) batteries. For remote on/off control, you can connect a relay or an open-collector output from a Li-ion BMS to the remote on-off port. Alternatively, you can fully control voltage and current via Bluetooth for complete, on-device management from your phone.
