Phoenix 48/250 Power Inverter

The Victron Phoenix 48/250 VE.Direct is a pure sine wave inverter designed to convert 48V DC power into 230V AC power, providing a continuous output of 250VA. This device is ideal for powering household and professional equipment in environments where grid power is unavailable or unstable.

Key Features:

• Pure Sine Wave Output: Ensures high-quality power, suitable for sensitive devices and advanced electronic equipment.

• High Efficiency: With its full-bridge design and toroidal transformer, the inverter achieves a maximum efficiency of 88%, minimizing energy losses.

• High Peak Power Capacity: Can handle power surges of up to 400W, which is essential for devices requiring high startup currents, such as motors and compressors.

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

• VE.Direct Connectivity: Allows monitoring and configuring the inverter via the VictronConnect app, available for mobile devices and computers.

• Built-in Protections: Includes safeguards against overloads, short circuits, high temperatures, and excessively low or high battery voltages, ensuring safe operation and extending the device’s lifespan.

Technical Specifications:

• DC Input Voltage: 48V
• AC Output Voltage: 230V ±3%
• Output Frequency: 50Hz or 60Hz (adjustable)
• Continuous Power Output at 25°C: 250VA
• Peak Power: 400W
• Maximum Efficiency: 88%
• No-load Power Consumption: 7.9W
• Dimensions (H x W x D): 85 x 165 x 260 mm
• Weight: 2.4 kg

Connectivity and Monitoring:

The VE.Direct port allows connection to computers, smartphones, and tablets via a VE.Direct to USB cable or a VE.Direct Bluetooth Smart dongle. Through the VictronConnect app, users can:

• Configure parameters such as low battery alarm levels, cut-off and restart voltages, and output voltage adjustment (between 210V and 245V).
• Monitor the real-time status of the inverter, including input/output voltages, current load, and alarm events.
• Update the firmware to access the latest improvements and features.

ECO Mode and Energy Efficiency:

ECO mode is a standout feature that enhances the inverter’s energy efficiency. When the connected load falls below a predefined threshold (minimum 15W), the inverter enters a low-power consumption state.

During this mode, the inverter briefly reactivates at adjustable intervals (default: every 2.5 seconds) to check if the load has increased. If it detects a rise above the set level, it returns to normal operation.

Installation and Safety:

To ensure optimal performance and safety, it is recommended to:

• Choose an appropriate location: Install the inverter in a dry place, protected from moisture and direct sunlight, with an ambient temperature between -20°C and 40°C.
• Ensure proper ventilation: Maintain a minimum clearance of 10 cm around the device for heat dissipation.
• Grounding: The inverter chassis must be properly grounded to comply with safety regulations and prevent electrical shocks.
• Use appropriately sized cables: Select battery cables with sufficient cross-sectional area to handle the required current and minimize voltage drops.
• Overcurrent protection: Install fuses or circuit breakers on the DC input circuit to protect the system from overloads or short circuits.

Typical Applications:

The Victron Phoenix 48/250 VE.Direct is versatile and suitable for various applications, including:

• Renewable Energy Systems: Converts stored energy from solar or wind power systems to supply AC devices.
• Recreational Vehicles & Marine Use: Provides AC power onboard RVs, boats, and yachts, enabling the use of household appliances and electronic devices.
• Backup Power Systems: Acts as an uninterruptible power source (UPS) for critical equipment during power outages.
• Industrial & Professional Applications: Powers tools and equipment in remote sites or areas without grid access.

Maintenance & Support:

Victron Energy is known for its commitment to quality and customer support. The Phoenix 48/250 VE.Direct requires minimal maintenance, but it is advisable to:

• Perform regular inspections: Check electrical connections and ensure there are no signs of wear or damage to the cables.
• Keep the unit clean: Remove dust and debris from ventilation areas to prevent overheating.
• Update the firmware: Use the VictronConnect app to keep the inverter updated with the latest software improvements.

The Victron Phoenix 48/250 VE.Direct is an excellent choice for those seeking a compact, efficient, and reliable inverter for off-grid or backup power solutions.
