TESVOLT IoT Architecture: The foundation for energy management, remote control, and energy trading

TESVOLT IoT Architecture connects batteries, inverters, and energy management systems — so your plant behaves like one coordinated system, not a collection of devices. It enables secure, real-time data exchange and remote control, making commissioning, monitoring, and ongoing operations dramatically easier.

The core element of the platform is TESVOLT IoT Gateway

The TESVOLT IoT Gateway is a local communication interface that connects the “physical world” (battery storage systems and inverters) with higher-level software systems such as energy management systems (EMS), cloud platforms, portals, and service tools. For the efficient exchange of measurement data and control commands, the IoT Gateway uses various protocols that were specifically designed for reliable IoT communication and remain stable even under challenging network conditions.

What the TESVOLT IoT Architecture Enables

Real-time measurements (1-second updates): The TESVOLT IoT Gateway transmits key electrical measurement values at 1 Hz for fast monitoring and highly responsive control – e.g. DC battery voltage, AC voltages, active power, and reactive power.

Parameter & status publishing: The TESVOLT IoT Gateway publishes device metadata and status information, ensuring that systems always have access to the latest known values – even after reconnects. Typical inverter states include: Standby, Error, Off, Running, and Islanding.

Remote access for operation and service: The TESVOLT IoT Gateway provides secure remote access to connected devices and enables operationally required control functions at device level. Multiple inverters can be uniquely identified and efficiently managed.

Built for mixed and growing systems: The TESVOLT IoT Gateway is designed for flexible integration – supporting different system types and mixed component setups (not limited to a single battery type or topology).

Monitoring & diagnostics: Detailed status and error reports help service teams quickly identify issues – additionally, connection status monitoring and payload integrity checks support robust system operation.

Security by design. The IoT Gateway protects system components through a separate network with no direct internet access.

TESVOLT IoT Gateway protects critical infrastructure with multiple layers, typically including:

  • Encrypted communication between TESVOLT Cloud and devices
  • Authentication & authorization for clients connecting to the gateway
  • Unique device identity (gateway + connected devices identified via serial/UID)
  • Audit logging of critical actions (commands, config changes, updates)
  • Secure updates (delivered via secure channels, with signing possible)

Less effort, more availability — with remote maintenance and over-the-air updates.

The TESVOLT IoT Architecture enables centralized remote maintenance and software updates for battery storage systems, inverters, and IoT components — across multiple sites and without the need for on-site intervention. This keeps systems easier to maintain, faster to update, and reliable over the long term.

For installers, this means:

  • fewer on-site service visits
  • faster troubleshooting and support
  • more efficient management of large system fleets

For operators and end customers:

  • igher system availability
  • continuous optimization and security updates
  • fewer operational interruptions and reduced maintenance effort
