Victron Phoenix Inverter 48/5000 230V Smart

The Victron Phoenix 48/5000 is a pure sine wave inverter designed for off-grid, backup and mobile power applications where a reliable 230V AC supply is needed from a 48V DC battery bank. With 5000VA continuous output and a 10000W peak surge capacity, it is suited to demanding loads including motors, compressors and power tools. The built-in VE.Direct Bluetooth Smart interface allows wireless monitoring and configuration without additional hardware.

Key Features

• 5000VA continuous pure sine wave output at 230V AC, suitable for sensitive electronics and motor loads.
• 48V DC input with a wide input voltage range, compatible with standard 48V lead-acid and lithium battery banks.
• Peak power capacity of 10000W handles high inrush currents from motors and compressors.
• Built-in VE.Direct Bluetooth Smart interface enables wireless monitoring and configuration via the VictronConnect app on iOS and Android.
• PowerControl and PowerAssist functions allow the inverter to supplement an AC source, preventing overload of a generator or shore power connection.
• Programmable relay for generator start/stop or alarm signalling.
• Comprehensive protection: over-temperature, overload, short circuit and low battery voltage shutdown.
• Compatible with Victron GX devices and the VRM online monitoring portal for remote system oversight.

Product Overview

The Phoenix 48/5000 uses a high-frequency transformer design to deliver a clean, stable 230V AC sine wave output. Pure sine wave output is essential when running equipment with active power factor correction, variable speed drives, or any load that would be damaged or destabilised by a modified sine wave. At 5000VA, this unit covers the majority of off-grid residential and light commercial load profiles, including refrigeration, water pumps and workshop equipment.

The VE.Direct Bluetooth Smart interface is integrated directly into the unit, so no external dongle is required. Using the VictronConnect app, an installer can view real-time input voltage, output load, battery state and alarm history, and adjust settings such as low battery cutoff thresholds and dynamic cutoff curves. This is particularly useful during commissioning and for remote fault diagnosis without visiting site.

When used alongside a compatible Victron charger or Multi unit, the PowerAssist function allows the inverter to draw additional power from the battery to supplement a limited AC source. This prevents a small generator from being overloaded during peak demand, extending generator life and reducing fuel consumption. The programmable relay adds further flexibility for automated generator start/stop control.

Installation Notes

This inverter operates at high DC currents from a 48V battery bank and must be installed by a qualified electrician or accredited installer. DC cabling must be correctly rated and fused in accordance with the system design. The unit is not grid-tied and does not require G98 or G99 notification, but any AC distribution connected to its output must comply with BS 7671 wiring regulations. Battery connections should be made in accordance with the battery manufacturer's specifications. Use the VictronConnect app during commissioning to verify input thresholds and protection settings before energising the load.
