Aphelion · Utility-Scale
Product overview
Arc is the broadest infrastructure boundary in Aphelion: a prefabricated energy cabin integrating PCS, transformer, medium-voltage switchgear, protection and EMS.
Aphelion is the farthest point in an orbit: a utility-scale series built around larger, more distributed energy infrastructure.

- 500 kW / 1.044 MWh
- Up to 500 kWp PV input
- Grid-connected and off-grid modes
Product architecture
Define the system boundary first
Rather than behaving like a conventional battery container, Arc coordinates conversion, transformation, switching, protection and control inside one engineered cabin.
Protection and control included
Protection and EMS are part of the coordinated prefabricated system architecture.
Central operating interface
A larger HMI, status lights and emergency stop are concentrated on the right-side functional area.

Final compatibility and project-specific settings are confirmed during system design.
Application fit
Start with the project
Application fit shows where to begin the engineering conversation. Final compatibility and performance are confirmed during project review.
Utility interconnection blocks
Consider Arc where multiple electrical infrastructure layers need one coordinated prefabricated boundary.
Microgrid infrastructure
Use the cabin as an integration point within a wider site control and generation architecture.
Distributed energy coordination
Define battery inputs, upstream connection and dispatch requirements before final system configuration.
Published technical data
Technical data by configuration
Compare the one or two mainstream configurations selected for this product. Final controls, protection and market-specific settings remain part of project design.
