Our EMS supports power conversion systems from Oztek.

Oztek designs power conversion systems (PCS) for commercial and industrial battery energy storage applications.

### Supported devices

-   **OZpcs Power Conversion System**: grid-tied battery power conversion system
-   **Generic**: generic Oztek power conversion system

The Oztek PCS connects over a standard **SunSpec Modbus TCP** interface, so no brand-specific adapter is required on the controller.

> **Warning**
>
> The Oztek PCS must be set to **Remote control** so it accepts the EMS setpoints. In local mode the system ignores the EMS and an incident is raised.

### EMS functionality

With the current integration, our EMS enables:

-   Monitoring of the power conversion system status and performance
-   Smart charging and discharging control
-   Optimization of self-consumption
-   Peak shaving and load balancing

Additional functionality may be added over time as integration capabilities evolve.
