Victron Filax 2 Automatic Transfer Switch CE 230V/50Hz-240V/60Hz | SDFI0000000

The Victron Filax 2 is an automatic transfer switch built for off-grid, marine and backup power systems that need a reliable changeover between two AC sources. It suits installers working with generator and inverter setups requiring fast, automatic switching without manual intervention.

Key features

• Automatic transfer, switches between two AC sources with no manual intervention required.
• Dual rating, compatible with 230V/50Hz and 240V/60Hz supplies.
• Certification, CE certified.
• Weight, 0.8 kg, suitable for panel mounting in confined spaces.
• Fast changeover, minimal interruption to connected loads when switching source.

How it works

The Filax 2 monitors the primary AC source continuously. If that source fails or moves outside acceptable parameters, the unit transfers the load to the secondary source automatically, then switches back once the primary source is restored. This is the behaviour needed where an inverter or generator backs up a shore or grid supply.

Its dual voltage and frequency rating means a single unit covers a 230V/50Hz system in the UK or Europe and a 240V/60Hz system elsewhere. That flexibility matters most in marine and mobile applications, where the local supply standard can change with location.

Applications

• Off-grid systems switching automatically between inverter output and generator supply.
• Marine and narrowboat installations changing over between shore power and an onboard generator or inverter.
• Motorhome and vehicle conversions with dual AC source setups.
• Backup power systems in residential or light commercial premises needing generator failover.

Installation notes

Fit the Filax 2 only with a qualified electrician familiar with AC distribution and transfer switching. Incorrect wiring of a transfer switch can cause back-feeding, equipment damage or a safety risk. For grid-connected UK installations, check the system design against G98 or G99 as applicable, and isolate all AC sources before working on the unit or its wiring.
