Product architecture

Applications

Architecture

The battery and conversion functions remain coordinated without being hidden in one cabinet. That makes the AC-side choice an explicit part of project configuration.

Inside Focal Vault

  • Outdoor battery cabinet
  • Right-side inverter or PCS module
  • Functional cabinet HMI

Applications

Outdoor C&I projects

Consider Vault where the storage system needs a cabinet-based outdoor equipment boundary.

Visible functional separation

Use the split architecture when battery and conversion equipment should remain physically legible.

Project-specific AC design

Choose the inverter or PCS path only after the site voltage, power and interconnection scope are confirmed.

Technical information

Technical data by configuration

Compare specifications by configuration. Controls, protection and local requirements are addressed during system design.
