DESCRIPTION

Victron VE Transfer Switch 10KVA: Automatic AC Source Selection for Critical Power Systems

Seamless Power Transition for Off-Grid, Backup, and Mobile Installations

The Victron VE Transfer Switch 10KVA provides reliable, automatic switching between two independent AC power sources. Designed for single-phase systems operating at 200–250 V AC, it ensures your loads remain powered without manual intervention. This unit is particularly effective in setups where continuity is essential, such as switching between an inverter and shore power, a generator and shore power, or between two separate AC supplies.

Unlike generic transfer switches, the Victron VE Transfer Switch is engineered with a fast, break-before-make mechanism that completes a source transfer within 10–20 ms when closing contacts and 5–20 ms when opening. This rapid response helps protect sensitive electronics from extended interruptions and reduces the risk of equipment resetting during changeover. The integrated auxiliary contact (200–240 V AC, 20 A, cos φ = 1) adds flexibility for signalling or controlling external devices, such as starting a generator automatically when the primary source fails.

Built for Demanding Environments

Housed in a robust IP54-rated enclosure, this transfer switch resists dust and water spray, making it suitable for installation in engine rooms, outdoor cabinets, and marine environments. The light grey RAL 7035 finish reflects heat and blends into standard electrical panels. A clear viewing window on the front cover allows quick visual status checks without opening the unit, while three bottom-entry cable glands provide secure, strain-relieved cable entry. Inside, colour-coded wiring and clearly labelled terminals for IN1, IN2, and OUT simplify installation and reduce wiring errors.

With a nominal current rating of 40 A per input and output, the switch supports loads up to 8 kW for electric motors, such as air-conditioning compressors. This makes it a practical choice for caravans, motorhomes, and marine vessels where air-conditioning startup currents are a concern. The low power consumption of just 6 VA on Input 1 and 0 VA on Input 2 minimises standby losses, preserving battery capacity in off-grid systems.

Key Features

  • Automatic break-before-make transfer between two AC sources
  • Fast switching: 10–20 ms (close) and 5–20 ms (open) for minimal disruption
  • IP54-rated enclosure with clear inspection window and cable glands
  • 40 A continuous rating per input/output, 8 kW motor load capacity
  • Auxiliary contact for generator start or external signalling
  • Adjustable input 1 delay (approx. 10 s) to prevent nuisance switching
  • Compact dimensions (175 x 215 x 120 mm) and lightweight (1.65 kg)

Applications Where Reliability Matters

This transfer switch is ideal for installations that demand uninterrupted AC power. Common use cases include:

  • Caravans and motorhomes: automatically switch between inverter and shore power when connecting to a campsite supply.
  • Marine vessels: manage shore power and generator inputs without manual changeover switches.
  • Backup power systems: integrate with battery inverters and generators for seamless failover during grid outages.
  • Remote off-grid sites: combine solar inverters with backup generators for extended autonomy.

By automating source selection, the VE Transfer Switch reduces the risk of operator error, such as back-feeding or leaving a generator running unnecessarily. It also eliminates the need for a separate manual changeover switch, simplifying system design and reducing installation time.

Installation and Integration

The unit is designed for straightforward integration into Victron Energy systems but is compatible with any AC power source within its voltage and frequency range (50–60 Hz). The adjustable input delay on Input 1 (approximately 10 seconds) allows customisation to match generator warm-up times or avoid transient switching. All terminals are clearly marked, and the DIN rail mounted internal components ensure secure connections even in high-vibration environments.

For systems requiring higher power handling, the 5KVA model is also available. However, for larger inverters or multiple high-demand appliances, the 10KVA version provides the necessary headroom to prevent overload and ensure long-term reliability.

Upgrade Your Power Reliability Today

Whether you are building a new off-grid system or retrofitting an existing installation, the Victron VE Transfer Switch 10KVA delivers the automatic, dependable source selection your setup needs. Add it to your system now and experience uninterrupted power, wherever you are.
