    Inverter with programming interface
    The invention relates to an inverter with a programming interface and in particular an inverter for a photovoltaic system.
    Inverters - also called inverters - are devices that convert a DC voltage into an AC voltage. Inverters are mainly used in photovoltaic systems to convert the direct current generated by photovoltaic modules into a single- or multi-phase alternating current. Further applications for inverters include uninterruptible power supplies, frequency converters or lighting equipment. Photovoltaic systems use different inverters, which differ not only in their functionality but also in their rated output. Each inverter is suitable for a specific power range. Especially the AC and DC nominal power are important for the functioning of the inverter. In a photovoltaic system, a plurality of solar modules can be connected in series with one another and in this way form a string or string of solar modules. For smaller photovoltaic systems, which have relatively few solar modules, solar modules are connected in series and connected to a central inverter. Larger photovoltaic systems use so-called string inverters.
    Furthermore, inverters differ in terms of their efficiency. For a photovoltaic system to operate in a maximum power range, i. In addition, as much electrical power as possible is produced, a so-called MPP tracker (MPP: Maximum Power Point) can be used in the inverter in the same way as in the case of the so-called MPP tracker. • • • • • • b§Ly'V ^: εε: sl ειοε / εο / 9ΐ
    be integrated. The power delivered by a photovoltaic system varies over the course of the day depending on environmental factors such as solar radiation, temperature and shading of the solar modules. The integrated in the inverter MPP tracker performs a self-adjustment of the inverter for a maximum current efficiency or the best possible function of the inverter by the voltage continuously adapts.
    Depending on the implementation, inverters can supply alternating voltages with different shapes, in particular a rectangular voltage, a trapezoidal voltage or a sinusoidal voltage.
    The circuit design and the functions provided by the various inverters of the photovoltaic system can thus vary.
    Some conventional inverters also have data interfaces that allow photovoltaic system data from the inverter to be read and processed. For example, conventional inverters are equipped with an RS232 or RS422 data interface, which makes it possible to read data from the inverter at an adjustable baud rate. For example, a PC for data evaluation can be connected to the serial data interface of the inverter.
    Conventional inverters have an inverter controller integrated therein that performs predetermined control software during operation of the inverter. The control software is firmly implemented to provide the main functions of the inverter. As a matter of fact, the following is the case: 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 170 L02 / 90/91 inverters therefore use standard inverter control software that is not adapted to the individual configuration of the respective system and that can not provide any individual additional functions desired by the respective user.
    It is therefore an object of the present invention to provide an inverter for a system, which makes it possible to adapt the functional scope of the inverter in a simple manner to the individual requirements of the plant and / or the plant operator.

The inverter 1 converts the DC voltage into an AC voltage or an AC current AC and feeds the AC current AC, for example, via a feed meter 4 into a power supply network 5. In the inverter 1 may be a foreign-guided or mains-powered inverter, which is intended to feed electrical energy from the DC side into the AC mains.
    In one possible embodiment, the inverter 1 is also designed to draw energy in the reverse direction from the power supply network 5 and convert it into DC voltage. In one possible embodiment, the inverter 1 is further designed to recognize this occurring network faults and the photovoltaic system 2 at least partially off. In this way overvoltages in a disconnected network section are avoided. Instead of solar modules, the system 2, for example, also fuel cells or the like, which provide a DC voltage. In the embodiment shown in Fig. 1 is a line-commutated inverter 1. Alternatively, the inverter 1 may also be a self-commutated inverter, which has selbstabschalt-bare flow valves, such as transistors or IGBTs, on and off of a clock signal which is generated locally by a clock of the inverter 1.
    The inverter 1 illustrated in FIG. 1 can generate a single-phase or polyphase alternating current and feed it into the power supply network 5. The waveform of the generated alternating current can vary. In one possible embodiment, the alternating current generated is sinusoidal. 9/31 8 £ 9S LHlttiin Qfr: Sl £ 10ΠΜΓ91 εεο / ziod • · • ♦
    As shown in FIG. 1, the inverter 1 has a programming interface 6, which in the illustrated exemplary embodiment is connected to a data network 7. The connection between the programming interface 6 and the data network 7 may, as shown in Fig. 1, be wired. Alternatively, a wireless connection between the data network 7 and the programming interface 6 is possible. The data network 7 may be a local data network or a local area network of a plant, in particular an industrial plant. Furthermore, the data network 7 can be a large network or a network of networks. In one possible embodiment, the data network 7 is formed by the Internet. As shown in Fig. 1, a terminal or a terminal 8 may be connected to a node of the data network 7, which can be operated by a user or user of the system 2. In one possible embodiment, the inverter 1 itself has a user interface, for example a graphical user interface GUI 9. In addition to the terminal 8, a server 10 is connected to the data network 7, which has access to a database 11. In this database 11 may be a variety of different inverter software components that can be loaded by a user or user of the system 2 as required via the programming interface 6 in the inverter 1. In one possible embodiment, the inverter 1 has at its delivery a basic configuration of software components to perform basic functions or main functions within the system 2. This basic software of the inverter 1 can be stored in a programming memory of the inverter 1, via the programming interface S of the inverter 1, it is possible, the main or 10/31 εεο / ε io 'd

    Extend basic functions of the inverter 1 with individual additional functions to suit the individual configuration of the system 2 and / or the needs of the user. The inverter software components, which are located, for example, in the database 11 of the server 10, can thereby be developed by end users of different systems 2, in particular by users of photovoltaic systems, or by third parties and transmitted to the server 10 for storage in its database 11. For example, inverter software components can be generated by an operator of a photovoltaic system at the terminal 8 of the photovoltaic system 2 and transmitted via the data network 7 to the server 10 for storage in the database 11. Furthermore, it is possible for a manufacturer of the inverter 1 to generate suitable inverter software components for different additional functions for different types of the inverters 1 produced by them and to make them available in the database 11 for charging. Furthermore, it is possible that each inverter 1 has an individual inverter identity or inverter identifier, for which respectively suitable inverter software components are stored in the data memory 11. The inverter software components stored in the database 11 thus come from a manufacturer of the inverter 1 or the photovoltaic system 2 as well as users or users of the system 2 or from third parties, such as engineering offices or the like. For a user of the system 2, it is possible to make an input via the user interface 9 of the inverter 1 in order to select a desired inverter software component and to readjust it in the respective inverter 1 for immediate or later execution

    9ε-sι ειοε / 5ο / 9ΐ the. Alternatively, the desired inverter software component can also be selected or selected via the terminal 8 of the system 2. The generated inverter software component request is transmitted to the server 10 via the data network 7. In this case, an identity information regarding the requesting inverter 1 and / or the system 2 is preferably additionally transmitted. The identity of the inverter 1 and / or the photovoltaic system 2 is checked or verified by the server 10. The server 10 can be operated, for example, by the manufacturer of inverters 1 and / or photovoltaic systems 2. For example, the manufacturer may operate a service portal for a library or collection of inverter software components.
    In order to ensure the safety and operational readiness of the system 2, in a preferred embodiment, the inverter software component reloaded via the programming interface 6 is first checked for its admissibility and subsequently for its safety, as shown in FIG. Before loading an inverter software component from the server 10 via the programming interface 6, a permissibility check of the respective inverter software component first takes place in a step S1. For example, power supply networks 5 have different fundamental frequencies in different countries. In Germany or Austria, for example, this fundamental frequency is 50 Hz. In other countries or countries, the fundamental frequency of the power supply network deviates from that. If the inverter software component has e.g. Influence on the setting of the frequency of the fed by the inverter 1 in the power supply network 5 AC or AC 12/31

    AC, can be checked by a verification module of the inverter 1 in step 31, whether the requested inverter software component for each state or the respective country in which the power network 5 is / permissible or is appropriate. For example, an inverter software component for an inverter 1 located in the US may be appropriate while being inadmissible or unsuitable for another inverter 1 'located in Germany or Austria.
    In a possible embodiment of the inverter 1 according to the invention, the programming interface 6 of the inverter 1 automatically establishes a data connection to a preconfigured network address of a server 10 of the data set node 7. This network address may be, for example, an IP network address or a URL (Uniform Resource Locator). This server network address may be preconfigured in a memory of the inverter 1 so that a data connection is automatically established to a particular server 10 from whose database 11 the desired inverter software components can be loaded. Depending on the configuration and / or location of the inverter 1, an automatic connection to an associated server 10 within the data network 7 can be established. For example, if the inverter 1 is deployed in or delivered to a particular state, the programming interface 6 establishes a data connection to the network address of a server 10 having access to inverter software components suitable for the respective state or power supply network 5 , 13/31 51 'S Μ'Μ m iU IUL SH LH5L ΕΙΟΠΜΠΙ εεο / 910'd «« * · * • · · · d • · · Dl · · · · · · ···· · · · m * · · · · · · ···············

    In a preferred embodiment of the inverter 1 according to the invention, a security check is carried out after the admissibility check 31 has been carried out in a further step S2 in order to determine whether the recharged inverter software component ensures safe operation of the inverter 1 and the installation 2. In one possible embodiment of the inverter 1 according to the invention, the inverter software component charged via the programming interface 6 of the inverter 1 is checked for the validity of a certificate of the inverter software component. Only when the validity of the certificate is recognized, the requested inverter software component is loaded, for example, in a program memory of the inverter 1 for immediate or later execution. Never recharged inverter software components or inverter modules can cause basic or. Expand or replace the basic functions of inverter 1. For example, access to certified inverter software components from a simple inverter can create a hybrid inverter. It is also possible to convert to further developed or other device types of the inverter 1 by recharging the corresponding certified inverter software components. The recharged via the programming interface 6 inverter software component can, for example, enable or extend a functionality already implemented in the inverter 1 functionality.
    If the admissibility check in step S1 and the safety check in step S2 are successful, an execution of the loaded inverter software components can take place in step S3, as shown in FIG. In one possible embodiment, the one which is programmed via the programmer 8895 in IHL in iwsi ειοπννηι εεο / ao'd

    Interface 6 of the inverter 1 interpreted inverter software component interpreted by an interpreter. In one embodiment, the programming interface 6 is programmed in its own proprietary programming language. In this embodiment, therefore, only commands can be used that are known to the respective interpreter. On the other hand, it is ensured that only one inverter 1, which has a corresponding interpreter, can interpret and execute the corresponding inverter software component.
    In an alternative embodiment variant, the software component downloaded via the programming interface 6 is executed as a machine code and possibly as an assembler code. The access to data and control elements can be realized here, for example, via a library or library. The library can handle a large part of the admissibility and security checks. Furthermore, the application or inverter software component may be stored in its own shadow-copied rootfs to hide the operating system. In one possible embodiment, both variants are combined in order to increase the safety and flexibility of the inverter 1. For example, a Python script can be interpreted in its own sandbox environment.
    The inverter software components or inverter software applications may be either published or private or proprietary. The publication of the inverter software components can be done for example via an online portal of the manufacturer. The user of a plant 2, in particular a photovoltaic system, has the option of using this online portal for his 15/31 n 's m' s »8 95 lb ML EM iMSl Ε10Π» Γ91 εεο / 8 lod

In one possible embodiment, upon receipt of the inverter software component by a user, a test of the developed inverter software component may be made by the manufacturer of the inverter 1 operating the portal. The tested inverter software component may be appropriately certified upon successful testing by the manufacturer of the particular type of inverter 1 and provided for loading by the server 10 to other users. In one possible embodiment variant, a user or user is informed before downloading an inverter software component whether or not the respective inverter component has been certified by the manufacturer as being safe in terms of safety or not.
    In another possible embodiment, a user or user has his own data format with which he processes data. Typically, the user already has various tools or tools that collect and process the data in this data format. The user or user of Appendix 2 therefore wants his data format also for the 21/31

    Use data that comes from the inverter 1 of his system. In this case, it is possible for the user or user of the system to develop his own inverter software component or a corresponding software module which encapsulates the data of the inverter 1 required by him in the data format preferred by him and delivers it for further data processing , This inverter software component can then be made available by the user or user to third parties via the portal of the server 10, for example.
    With the system according to the invention it is possible to provide inverter software components which support any data transmission protocols, in particular IP-based data transmission protocols. The additional protocols allow users to read, process and send data accordingly. This facilitates the integration into larger or more extensive systems since, from the user's point of view, there is no longer any dependency on a software manufacturer. For example, this larger system may be a so-called mixed-concept system. In a mixed-concept system, power units are switched off with less power production. This saves operating hours and increases efficiency. With the help of an inverter software component, a user has the opportunity to implement this functionality according to their own wishes and requirements.
    For example, a user may require a particular signal if an inverter 1 satisfies a set of adjustable or configurable rules. For example, a signal is needed if, over an adjustable period of time, a signal is received
    017: SL 0LOZ / SO / 9L parameterized power value is not exceeded or undershot. Furthermore, a signal can be generated or needed when a maximum or minimum value has been reached.
    Furthermore, with an inverter application, a controlling influence on the power production can be made possible, wherein a connection to ripple control receivers or other higher-level control systems can be realized. A user can use a proprietary protocol using an inverter software component, allowing the product to be flexibly integrated into any system. A user or customer has the opportunity to define self-assembled elements. A newly defined element can be integrated and put into operation as an inverter software component, for example as a plug-in, for the Graphical User Interface GUI 9 and / or a web page. The available inverter software components are predefined and freely applicable, for example, in terms of their position on a display unit, in terms of the displayed values or graphics displayed, and so on. The compilation of the inverter software components can be made on the device. For example, an inverter software component may display a favorites list or make language adjustments. Furthermore, a user or user of Appendix 2 can incorporate support for his language. Furthermore, it is possible that a system integrator obtains inverter 1 from a manufacturer and adapts it by inverter software components in such a way that a separate branding and an associated extension of the functional scope is displayed. This is achieved, for example, by adaptation by means of the user interface 9 of the inverter 1. The 23/31

The inverter 1 can also be used in other applications or other installations, such as uninterruptible power supplies or in frequency converters. The inverter 1 may be a module inverter, a string inverter or even a central inverter of a photovoltaic system 2. The inverter software components may use the programming interface 6 provided in the inverter 1 to cause an operating system of the inverter 1 to perform the actions provided by it. The user or user has the opportunity to program their own additional functions and thus the possibility of extending the inverter software components with their own functions. 24/31
