Transfer switches switch between two power sources – for example, shore power and a generator. Choose according to amperage and whether the switch should be manual or automatic.
Victron VE Transfer switch 5KVA/230V – automatic transfer switch between two AC sourcesThe Victron VE Transfer Switch 5 kVA is an automatic transfer switch with two AC inputs and one output. The loads are supplied from input 1 (e.g. shore power or a generator), and if this supply fails or goes outside the voltage or frequency limits, the switch automatically changes over to input 2 – typically an inverter. During the switchover itself, the power is briefly interrupted, so sensitive electronics such as computers may lose data.Benefits
Automatic switching: Switches between the two sources without manual operation.
Delayed switch-back: Once input 1 has been stable for approx. 10 seconds (adjustable), it switches back – this protects your equipment during short voltage dips.
20 A per input: Rated current of 20 A on both inputs and the output, and motor loads (e.g. air conditioning) of up to 1.3 kW.
Auxiliary contact: Together with a MultiPlus and a Digital Multi Control, it can automatically switch the current limit to a preset generator value.
Applications
Switching between generator and shore power in boats or motorhomes.
Switching between inverter and generator or shore power.
Giving a MultiPlus access to two AC sources instead of one.

Victron Filax-2 110V/50 Hz-120V/60 Hz – ultra-fast automatic transfer switch for sensitive loadsThe Victron Filax-2 is an ultra-fast automatic AC transfer switch. Normally, the loads are supplied from a priority source such as the grid, shore power or a generator; if the voltage or frequency falls outside the limits, the Filax-2 switches over to an alternative source – typically an inverter – within a maximum of 16 ms, so computers and other sensitive electronics can keep running without interruption. It is not intended for large household appliances such as washing machines or electric motors. This version is for 110 V/50 Hz and 120 V/60 Hz installations – for standard Danish 230 V systems, you need the 230 V version.Benefits
Ultra-fast switching: Switches between the sources within a maximum of 16 ms.
Monitors voltage and frequency: Switches to the alternative source if the voltage on the priority source is too low or its frequency is too low/high.
Automatic switch-back: Switches back to the priority source once it has been within the limits for 30 seconds.
Robust enclosure: IP65 ABS enclosure for operation from -20 to +50 °C.
Applications
Computers, network equipment and industrial controls that must not restart during a power failure.
Entertainment electronics in boats or motorhomes when switching between shore power/generator and inverter.
Fixed installations where an inverter provides backup for sensitive loads.
