Description
xVictron Energy Autotransformer 120/240V 32A — ITR000100001
The Victron Energy Autotransformer 120/240V-32A is a split-phase voltage conversion unit designed for installations where 120V and 240V AC distribution is required from a single-phase source. It is suited to off-grid systems, marine applications, and North American-standard electrical setups where split-phase power is needed. At 32A continuous rating, it handles substantial loads without the bulk and cost of a full isolation transformer.
Key Features
- Converts between 120V and 240V split-phase AC, enabling North American-standard distribution from a single-phase input.
- 32A continuous current rating supports high-demand loads across both legs of a split-phase system.
- Autotransformer design is more compact and efficient than a full isolation transformer for voltage-splitting applications.
- Compatible with Victron inverter/charger systems, allowing split-phase output from a single MultiPlus or Quattro unit.
- Robust toroidal core construction keeps no-load losses low and reduces audible hum during operation.
- Weight of 12.8 kg reflects a substantial copper-wound core, appropriate for the rated current capacity.
Product Overview
An autotransformer differs from an isolation transformer in that the primary and secondary windings share a common electrical connection rather than being magnetically isolated. This makes it well suited to voltage-splitting duties, where the goal is to derive a 120V/120V split-phase output from a 240V single-phase source, or to combine two 120V legs into a 240V supply. The shared winding means lower copper losses and a more compact unit for a given power rating compared to a fully isolated design.
In practice, this unit is commonly used alongside Victron MultiPlus or Quattro inverter/chargers in North American off-grid or marine installations. A single inverter producing 240V AC can feed the autotransformer to create the balanced 120V/120V split-phase supply that North American appliances and distribution panels expect. The 32A rating at 240V equates to a maximum throughput of approximately 7.68kVA, which covers most residential and light commercial off-grid loads.
Because this is an autotransformer and not an isolation transformer, it does not provide galvanic isolation between input and output. Where isolation is a safety or regulatory requirement, a separate isolation transformer must be used. Installers should confirm the requirements of the installation before specifying this unit.

Installation Notes
This autotransformer must be installed by a qualified electrician familiar with split-phase AC systems. It does not provide galvanic isolation, so it is not a substitute for an isolation transformer where isolation is required by regulation or for safety. Ensure all wiring is rated for the full 32A load and that appropriate overcurrent protection is fitted on both the input and output sides. Confirm compatibility with your inverter or AC source before installation. For marine installations, check compliance with applicable shore power and electrical safety standards.
