Product Overview

The Victron Energy Phoenix 48/375 Direct Schuko (PIN483750200) steps up from the entry-level 48/250 to deliver 375VA continuous output (300W at 25°C / 260W at 40°C) and a 700W peak power rating from a 48V battery bank. The additional capacity makes it suitable for a broader range of AC loads in 48V off-grid solar systems, commercial installations, and industrial setups CPAP machines, power tool chargers, moderate-draw electronics, and small appliances that sit above what the 48/250 can sustain continuously.

At 90% maximum efficiency a step up from the 88% of the 48/250 the Phoenix 48/375 keeps conversion losses lean across the 48V input range of 36.8–62.0V. Fan-assisted cooling, a −40°C to +65°C operating range, and the full suite of configurable 48V voltage protection settings make it equally at home in a hot Australian off-grid equipment enclosure or a cold-climate industrial installation. Like all Phoenix Direct Schuko models, it provides a direct Schuko AC outlet, remote on/off, and ECO mode standby making it as straightforward to install as it is reliable in service.

Note: This product is a standalone inverter only it does not include a battery charger. It is not suitable for connection to mains AC supply.

Features & Benefits

• 375VA continuous 50% more than the 48/250: The step up from 250VA to 375VA opens the door to loads the 48/250 cannot sustain: CPAP machines, power tool battery chargers, small kitchen appliances, audio amplifiers, and combinations of smaller simultaneous loads in 48V off-grid, commercial, and industrial installations. Where the 48/250 left headroom too tight, the 48/375 provides it.
• 90% maximum efficiency improved over the 48/250: At 90% peak efficiency versus 88% on the 48/250, the Phoenix 48/375 loses less energy as heat during conversion extending usable battery runtime and reducing the charge energy required to recover the 48V bank after each cycle. In large off-grid solar systems cycling daily, that 2% improvement compounds meaningfully over a season.
• 48V input minimal DC current draw: At 375VA from a 48V source, the DC input current is a fraction of what equivalent 12V or 24V inverters would demand. Minimal cabling, minimal resistive losses, and minimal heat in the DC input circuit the right choice for any installation already built around a 48V battery bank.
• Full bridge plus toroidal transformer pure sine wave output: Victron's proven professional inverter topology delivers grid-quality pure sine wave output. CPAP machines, modern switching power supplies, audio equipment, and sensitive electronics all operate cleanly no motor noise, no interference, no compatibility issues.
• 700W peak power: Handles inrush current from LED lamp converters, halogen lamps, and small power tools on startup loads that draw significantly more at switch-on than during steady-state operation.
• 2.6W ECO mode standby: In ECO mode, standby draw drops to 2.6W keeping overnight parasitic drain minimal in always-on 48V installations with intermittent AC load use. The 2.5-second retry interval (adjustable) ensures loads reconnect promptly.
• Fan-assisted cooling across −40°C to +65°C: Thermally controlled fan cooling maintains rated output under sustained load and in hot Australian conditions. Thermal derating is a gradual 1.25% per °C above 40°C usable output rather than abrupt shutdown under heat.
• Fully configurable 48V voltage protection: DC low shutdown (37.2V), restart (43.6V), and battery charged detect (56.0V) thresholds are all user-adjustable for 48V LiFePO4 or lead-acid chemistry. Dynamic cutoff raises the cutoff voltage proportionally under heavier loads protecting against deep discharge at high draw while avoiding nuisance trips under light loads.
• Remote on/off: Two-pole remote connector allows switching from a system control panel, BMS load-enable output, or site management circuit without routing heavy 48V battery cables to the switch.
• Integrated Schuko socket: Direct 230VAC Schuko outlet compatible with standard Australian and European plugs. No additional socket wiring required.
• Short circuit proof and overtemperature protected: Automatic shutdown under fault conditions with clean recovery once conditions normalise.

Frequently Asked Questions

How does the Phoenix 48/375 differ from the Phoenix 48/250?

The 48/375 delivers 375VA continuous and 700W peak versus 250VA and 400W on the 48/250 a 50% increase in continuous capacity and 75% more peak power. It also achieves 90% maximum efficiency versus 88% on the 48/250. It is suited to CPAP machines, power tool chargers, and moderate-draw appliances that exceed the 48/250's continuous rating.

Is this inverter suitable for powering a CPAP machine from a 48V off-grid system?

Yes, provided the CPAP machine's power draw falls within the 375VA continuous rating. CPAP machines require clean pure sine wave output which the Phoenix 48/375 provides. Confirm your CPAP machine's watt rating against the inverter's capacity, and disable ECO mode if the CPAP requires uninterrupted power throughout the night.

Can the voltage thresholds be configured for a 48V LiFePO4 battery?

Yes. DC low shutdown (37.2V default), restart (43.6V), and battery charged detect (56.0V) are all fully user-adjustable for 48V LiFePO4 voltage ranges. Consult the Victron Phoenix inverter manual and your battery manufacturer's recommended discharge limits before configuring thresholds.

Does ECO mode affect loads requiring continuous power?

ECO mode cycles the inverter through brief standby periods when load falls below 15W suitable for intermittent-use loads but not for equipment requiring uninterrupted power. For medical devices, computers, or any load sensitive to power cycling, disable ECO mode so the inverter stays on continuously.

Does this inverter include a battery charger?

No. The Phoenix 48/375 is a standalone pure sine wave inverter only with no battery charger or AC input. For combined 48V inverter and charger functionality including shore power input, PowerAssist, and UPS transfer refer to the Victron MultiPlus-II range.
