    Park controller according to VDE 4105 and NELEV (Solar package 1)

    • For systems connected to low voltage, the general requirements of VDE 4105 apply.
    • For systems connected to medium voltage, an EZA controller and certification were previously required from 135 kW Pav,e upwards.
    • With the introduction of the NELEV, there are now exceptions to this rule.
    • The new NELEV regulations (Solar Package 1) came into effect on May 17, 2024, aiming to simplify and accelerate PV expansion.

    Systems that meet the following criteria fall under the new regulation:

    • Total generation capacity (PV, battery storage, CHP, etc.) is below 500 kW
    • Feed-in limitation of maximum 270 kW (Pav,e)

    • Our grid operator requires remote control technology. How does that work?

      Many grid operators require remote control technology from certain system sizes onwards. With SmartDog, this function is already integrated, so in many cases no additional hardware or separate provider is required.

      SmartDog supports different connection types such as IEC 101, IEC 104, digital contacts, analog signals and Modbus TCP. This makes it easy to implement the right remote control solution in a practical way.

       

    Systems according to NELEV (Solar Package 1)

    • I don't know how my large-scale installation is classified - VDE 4105 or 4110?

      If a system is connected to low voltage, the VDE 4105 regulations always apply. For systems connected to a medium-voltage or high-voltage transformer, a distinction has been made since May 2024. Previously, a grid controller and certification were required for systems with a capacity of 135 kW or more. 

      Exceptions now exist under the NELEV (New Electricity Grid Expansion Ordinance). The new NELEV regulations (Solar Package 1) have been in effect since May 17, 2024, and are intended to simplify and accelerate the expansion of photovoltaics.

      Systems that meet the following criteria fall under this new regulation and are classified as VDE 4105: Total generation capacity of the system under 500 kW (PV, storage, CHP, etc.) Feed-in limit of max. 270 kW (PV, E)

    • Do I need a park controller for NELEV (Solar Package 1) systems?

      Yes, for NELEV (Solar Package 1) systems with an output above 270 kW and below 500 kW that must be limited to 270 kW feed in power, a PAV,E control system is required. This limitation must be implemented by a suitable PAV,E controller. The specified control limits, known as the envelope curve, must be followed very precisely.

      If the controller does not react fast enough, the system may be shut down, for example during rapid changes between sun and clouds. The certified SmartDog PAV,E controller meets these requirements and controls the inverters at 200 millisecond intervals.

    • Can I use simple meters for a NELEV system with PAV,E control?

      No, simple meters are generally not sufficient for a NELEV system with PAV,E control. Many grid operators require high accuracy classes for the measuring devices used. Depending on the specification, this also includes very precise measurement of voltage, current and current transformers.

      These requirements can only be met by high quality measuring devices. With ecodata solutions GmbH, you receive a coordinated package that meets the relevant requirements and is designed for use with SmartDog.

       

    • Can I use any inverter?

      Not every inverter is suitable for every application. If PAV,E control is required, the inverters used must also have the appropriate PAV,E certification. This is the only way to ensure that the required control specifications are met reliably.

      With SmartDog, the right solution for grid compliant system control can be implemented effectively.

    • Do I also need a park controller for systems below 270 kW?

      Even for systems below 270 kW, requirements for remote control technology, reactive power control, active power control or connection to a direct marketer may still apply. With SmartDog, these functions are already integrated, which means that in many cases no additional hardware is required.

      SmartDog meets the relevant requirements of different grid operators and provides a practical solution for grid compliant control and communication. This gives you a reliable all in one solution.
