TESVOLT Energy Controller Pro L
The new standard for battery park management: integration, control and marketing all in one

Battery park management with the right farm controller

Operating battery parks is no less challenging than obtaining the necessary permits:

  • Diverse, international components
  • Strict grid requirements (e.g. VDE 4110/4120)
  • Marketing requires real-time data and therefore IoT connectivity
  • Potentially at risk as critical infrastructure

▶️ Without centralised control, safe and economical operation is impossible!

The solution: one platform instead of multiple interfaces

The TESVOLT Energy Controller Pro L connects all the components in the battery park.

Areas of application

For all BESS battery parks and projects exceeding 5 MWh.

Security of supply (municipal utilities)

Municipal utilities and energy suppliers must safeguard critical infrastructure whilst meeting increasing demands for security of supply and resilience. Battery storage systems play a central role in this – from grid stabilisation to blackout prevention. In an emergency, the TESVOLT Energy Controller Pro L enables the coordinated operation of the systems and supports a rapid restart of the energy infrastructure following power cuts.

Co-location projects

Existing grid connections become a bottleneck when additional generation or storage capacity needs to be integrated. Co-location allows battery storage systems and new PV or wind power plants to be connected to existing grid connections, making optimal use of the existing infrastructure. This enables grid capacity to be utilised efficiently, reduces investment costs and speeds up project implementation.

Trading Applications

Marketing storage flexibility requires the precise execution of schedules and trading signals from various energy markets. The TESVOLT Energy Controller Pro L processes market operators’ instructions in real time, controls the connected storage systems accordingly, and simultaneously ensures compliance with all grid requirements. This combines energy trading and grid compliance within a single centralised platform.

The TESVOLT Energy Controller Pro L is not a traditional EMS – but rather the central control unit linking the grid operator, the energy supplier and the battery system.

Why choose the TESVOLT product?

With the TESVOLT Energy Controller Pro L, we offer not just hardware, but genuine system expertise:

  • Open to all manufacturers and tailored to specific projects
  • Proprietary control logic for implementing grid and trading signals (Dispatcher)
  • Quickly expandable
  • Maximum data sovereignty and security through the TESVOLT IOT-gateway with Endian firewall/VPN and protection against unauthorised external access
  • Can be integrated into existing systems (as a client under a server) – ideal if an EZA solution is already in place (e.g. in co-location projects)
  • Industry-proven WAGO components

TESVOLT Energy Controller Pro L – the central control unit for safe and cost-effective operation

The TESVOLT Energy Controller Pro L acts as the central control unit for the battery park. It processes grid operator specifications, the energy trader’s schedules, and the status data from batteries and inverters in real time.

On this basis, it controls energy flows, ensures compliance with technical requirements and transmits all relevant operational data to the TESVOLT Portal.
