The Victron Phoenix Inverter 48/1200 is a pure sine wave inverter built for 48V battery systems, converting DC power into a 230V AC supply at 1200VA continuous output. It suits off-grid installations, marine and vehicle setups, and backup power systems where a clean AC supply matters. A VE.Direct port lets it talk to compatible Victron monitoring devices and controllers.

Victron phoenix inverter key features

• Output, 1200VA continuous, pure sine wave.
• DC input, 48V, suited to lithium and lead-acid battery banks.
• Communication, VE.Direct port for connection to Victron MPPT controllers, Color Control GX and other VE.Direct compatible devices.
• AC output socket, SCHUKO, for direct appliance connection.
• Protection, low battery voltage, high battery voltage, overload, short circuit and over-temperature.
• Weight, 6.9 kg.

Product overview

Pure sine wave output means the Phoenix 48/1200 works with AC loads that struggle on modified sine wave inverters: variable speed drives, compressors, medical equipment, and audio-visual gear. Running at 48V DC is common on larger off-grid systems, since a higher battery voltage draws lower current for the same power, which cuts cable losses and heat.

VE.Direct is Victron's point-to-point serial protocol. Connected to a Victron GX device, a VE.Direct to USB interface, or a compatible MPPT charge controller, it gives real-time visibility of inverter status, load and battery data. The SCHUKO socket is standard across continental Europe and also common in the UK for portable or semi-permanent setups, letting appliances connect directly without a separate consumer unit.

Applications

• Off-grid cabins and remote buildings run from a 48V battery and solar system.
• Marine vessels needing 230V AC from a 48V DC house bank.
• Motorhomes, campervans and expedition vehicles with 48V electrical systems.
• Backup power for critical loads during grid outages, connected to a 48V battery bank.
• Telecoms and industrial enclosures needing a monitored, standalone AC supply.

Installation notes

This is a 48V DC product and should be installed by a qualified electrician familiar with DC battery systems. DC cable sizing must suit the maximum current draw at 48V. The VE.Direct port carries data only, not power. Where used as part of a grid-connected or grid-backup system in the UK, the installation should comply with G98 or G99 requirements as applicable, and battery connections should be fused as close to the terminals as possible per the manufacturer's guidelines.
