Split-Phase and Neutral-Forming Auto Transformers for Renewable Energy Systems

Custom-built for solar, wind, and battery storage systems, with step-down and neutral-forming capabilities engineered for performance

Auto transformers are ideal for applications where voltage conversion or phase balancing is required, but full electrical isolation is not necessary. Amgis designs both split-phase and neutral-forming auto transformers to meet the unique demands of renewable installations.

Key Applications in Clean Energy

Our custom auto transformers are well-suited for residential, commercial, and industrial-scale systems, and are built for:

  • Solar inverters, especially for off-grid and hybrid systems
  • Battery storage systems where a neutral or split phase is required
  • Wind turbines for voltage matching and system grounding
  • Distributed generation projects requiring flexible power conversion
