Victron Phoenix Smart IP43 24V 25A Charger

The Victron Phoenix Smart IP43 24V 25A 1+1 has a main house output and an auxiliary starter output, accepting 120-240V AC.

Twenty-four volts is the specification to confirm first, since the 12V Phoenix Smart models will not serve a 24V system whatever the amperage matches. Larger vessels and boats with thrusters or windlasses commonly run 24V house systems, which is where this belongs.

The 1+1 layout sends the bulk of the 25 amps to the service bank while a smaller maintenance current keeps the starter battery topped up from the same unit. That matches how the two banks are actually used, rather than splitting capacity evenly between a bank that does the work and one that barely discharges.

Bluetooth through VictronConnect covers setup, monitoring, alarms, synchronization and firmware updates without physical access. The adaptive charging process varies absorption by discharge depth, and auto-ranging 120-240V input works on shore supplies in either region. IP43 suits a protected installation.
