Phoenix 48/800 VE-Direct Power Inverter

The Victron Phoenix 48/800 VE.Direct is a pure sine wave inverter designed to convert 48V direct current (DC) into 230V alternating current (AC), providing a continuous power output of 800VA. This device is ideal for powering domestic and professional equipment in locations where grid power is unavailable or unstable.

Main Features

Pure sine wave output: Ensures a high-quality power supply suitable for sensitive devices and advanced electronic equipment.

High efficiency: Thanks to its full-bridge technology and toroidal transformer, the inverter achieves a maximum efficiency of 88%, minimising energy losses.

High peak power capacity: It can handle power surges of up to 1,500W, which is essential for devices requiring a high start-up current, such as motors or compressors.

ECO mode: When the load drops below a preset value, with a minimum threshold of 15W, the inverter enters standby mode to save energy. It automatically reactivates when the load increases again.

VE.Direct connectivity: Allows the inverter to be monitored and configured through the VictronConnect application, available for mobile devices and computers.

Built-in protection systems: Includes protection against overloads, short circuits, high temperatures, and excessively low or high battery voltages, ensuring safe operation and extending the service life of the device.

Connectivity and Monitoring

The VE.Direct port allows the inverter to be connected to devices such as computers, smartphones and tablets using a VE.Direct-to-USB cable or a VE.Direct Bluetooth Smart dongle.

Through the VictronConnect application, users can:

Configure parameters such as low-battery voltage alarm levels, shutdown and restart voltages, and adjust the output voltage between 210V and 245V.

Monitor the inverter’s status in real time, including input and output voltages, current load and alarm events.

Update the device firmware to access the latest improvements and features.

ECO Mode and Energy Efficiency

ECO mode is a key feature that improves the inverter’s energy efficiency. When the connected load falls below a predefined threshold, with a minimum setting of 15W, the inverter enters a low-power state, reducing energy consumption.

While operating in this mode, the inverter briefly reactivates at adjustable intervals—every 2.5 seconds by default—to check whether the load has increased. When it detects an increase above the preset level, it returns to normal operating mode.

Installation and Safety Recommendations

Earth connection: The inverter chassis must be properly earthed to comply with safety regulations and prevent possible electric shocks.

Correct cable sizing: Battery cables with an appropriate cross-sectional area must be used to handle the required current and minimise voltage drops.

Overcurrent protection: Appropriate fuses or circuit breakers must be installed in the DC input circuit to protect the system against possible overloads or short circuits.

Typical Applications

The Victron Phoenix 48/250 VE.Direct is a versatile inverter that is ideally suited for:

• Renewable energy systems

• Recreational vehicles and marine applications

• Backup power systems

• Industrial and professional applications, powering tools and equipment at remote sites or in areas without access to the electricity grid
