Victron Autotransformer - Split Phase 120/240V - 100AMP

Victron Autotransformer - Split Phase 120/240V - 100 AMP is a versatile solution for step up, step down, and split-phase balancing in home and off-grid systems. Designed to maximize your 120/240V availability, it helps you use every amp of a 30A split-phase supply more efficiently.

Key capabilities:

• Step up / step down and split-phase balancing: Adjust voltages and balance 120V/240V loads on a single split-phase supply to prevent one leg from pulling more current than the other.
• Maximize usable power: In a 30A, 120/240V setup, unbalanced loads can reduce practical capacity. The autotransformer absorbs load unbalance, enabling higher total output and more even current on both legs (example: near theoretical 7.2 kVA when balanced, with unbalance managed by the transformer).
• Temperature protected: If overheating occurs, the unit disconnects from the supply with a manual reset to keep your system safe.
• Grounding relay for Multi or Quattro inverter/chargers: Includes a built-in grounding relay to guarantee proper grounding for GFCI operation. When using in inverter mode, connect the inverter/charger neutral to ground and disable the internal grounding relay on the inverter if required.
• Alternative to stacking inverters: Instead of stacking two 120V inverters for a 120/240V split-phase, pair a 240V inverter with this autotransformer for a neat, reliable solution.
• Neutral handling and balance: By using the autotransformer to create a new neutral, load imbalance is absorbed within the transformer windings, allowing both 120V legs to operate at consistent current levels and unlocking full system capacity.

Designed for dependable performance in practical installations, this autotransformer is a smart addition to Victron-based power systems, delivering robust split-phase capability while protecting and simplifying your wiring approach.
