The Victron Phoenix Inverter 48/800 converts 48V DC battery power into 230V AC pure sine wave output at 800VA continuous. It suits off-grid and backup installations across marine, vehicle, telecoms and remote power systems, and includes a VE.Direct port for monitoring and configuration without extra hardware.

Key features of the Victron Phoenix inverter 48/800

• Output, 800VA continuous, pure sine wave AC, suitable for sensitive electronics and motor loads.
• DC input, 48V, compatible with standard 48V lead-acid and lithium battery banks.
• Monitoring, VE.Direct port for connection to Victron GX devices and BMV battery monitors.
• AC connector, IEC output for standardised wiring in professional installations.
• Protection, low battery voltage shutdown, over-temperature and overload protection, with automatic restart once the fault clears.
• Efficiency, a design intended to keep standby power draw low, which matters in off-grid systems with finite battery capacity.

Product overview

Pure sine wave output means this inverter works with all AC load types, including inductive loads like motors, compressors and transformers, as well as electronics that a modified sine wave inverter would disrupt. At 800VA it is sized for a single circuit or a small group of loads rather than a whole property, making it a fit for targeted backup or off-grid power in one zone or one piece of equipment.

VE.Direct is Victron's serial communication interface. On this inverter it connects to the GX device ecosystem for remote monitoring, on/off control and data logging, without needing a separate communications module. The IEC output connector is fixed on this variant, distinguishing it from the terminal block version, and suits a direct plug-in connection to an IEC lead or distribution board.

Applications

• Off-grid cabins, lodges and remote buildings needing a dedicated 230V AC supply from a 48V battery bank.
• Marine and narrowboat installations running a 48V DC system alongside 230V AC equipment.
• Vehicle and motorhome conversions built around a 48V battery architecture.
• Telecoms and industrial enclosures needing a reliable AC supply with remote monitoring.
• Backup power for critical single-circuit loads in commercial or agricultural premises.

Installation notes

This inverter runs on a 48V DC supply and should be connected through correctly fused, appropriately rated DC wiring by a qualified electrician or accredited installer. The IEC AC output is not for direct connection to a building's fixed wiring without proper isolation and protection devices. It is not grid-tied and does not require G98 or G99 notification. Keep ventilation clear around the unit to avoid thermal shutdown under sustained load.
