Victron Energy Autotransformer – 120/240V, 32A
Step-Up, Step-Down & Split Phase Load Balancing
The Victron Autotransformer 120/240V – 32A is a versatile power management tool designed for step-up, step-down voltage conversion and split-phase output balancing. Ideal for off-grid, marine, and backup applications, it ensures optimal load distribution and maximizes system efficiency—especially where 120V and 240V loads coexist.
Key Applications:
-
Step-Up or Step-Down Voltage Conversion
Converts 120V to 240V or vice versa as needed for system flexibility. -
Split-Phase Output Balancing
Perfect for 120/240V systems with unequal 120V loads—absorbs load imbalances to maintain full capacity usage. -
Alternative to Stacked Inverters
Offers more flexibility and higher unbalanced load capability compared to stacked 120V inverter setups.
Technical Benefits:
-
Maximizes Load Capacity
Ensures full use of a 30A 120/240V supply (up to 7.2kVA) even under unbalanced conditions by rerouting neutral current through the transformer. -
Integrated Ground Relay
Automatically grounds the inverter's neutral in inverter mode to comply with GFCI requirements. Controlled via Victron Multi or Quattro inverters. -
Temperature Protection
Automatically disconnects during overheating. Manual reset ensures safety.
Why Choose an Autotransformer Over Stacked Inverters?
- A single 240V 5kVA inverter paired with a 32A autotransformer supports more unbalanced load than two stacked 120V inverters.
- Enables up to 38.5A on one leg if the other leg remains lightly loaded.
- Ideal for systems with fluctuating or unbalanced 120V appliance use.
Specifications:
- Input/Output Voltage: 120/240V
- Current Rating: 32A
- Includes: Grounding relay for neutral bonding
- Protection: Over-temperature shutdown with manual reset
- Application: Off-grid, RV, marine, residential backup, generator systems
Ensure stable voltage, efficient power distribution, and full load utilization with the Victron Autotransformer. An essential upgrade for any split-phase or multi-voltage energy system.
