Description
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. It helps you maximize 120/240V availability and use every amp of a 30A split-phase supply more efficiently. Note: California Prop 65 warning applies.
- Split-phase compatibility: 120/240V autotransformer capable of balancing loads across both legs.
- 100 A capacity: Designed to manage up to 100 Amps across the split-phase system, improving utilization of a 30A supply.
- Step up / Step down: Allows adjusting voltages to match loads and improve performance.
- Load balancing: Absorbs imbalance to keep currents on each leg more even, approaching 7.2 kVA when balanced.
- Thermal protection: Temperature protection with manual reset to safeguard the system.
- Grounding relay and GFCI compatibility: Built-in grounding relay for proper grounding in complex inverter/charger configurations; guidance for inverter mode operation.
- Neutral handling: Creates a new neutral inside the autotransformer to balance loads within windings and unlock full system capacity.
- Alternative to inverter stacking: Pair a 240V inverter with this autotransformer for a neat, reliable split-phase solution instead of stacking two 120V inverters.
- Dependable Victron integration: Designed to work seamlessly in Victron-based power systems, delivering robust split-phase capability while simplifying wiring.
- Prop65 Warning: This product carries California Prop 65 warning.
This autotransformer helps you squeeze more usable power from a 30A split-phase 120/240V system by balancing loads across both legs and absorbing unbalance within the windings. It simplifies wiring, supports GFCI operation, and provides protective features like automatic shutdown on overheating. Whether you're expanding an off-grid setup or optimizing a Victron-based installation, this unit offers a compact, reliable path to full split-phase capability without needing to stack extra inverters.
