Description

Information transmission and reception control method and system for AC module including PV panel

[0001] The present invention relates to a method for controlling the transmission and reception of information, and more specifically, to a method for controlling an AC module including a PV panel for solar power generation to transmit and receive various types of information, and a system for implementing the method.

[0002] Solar power generation is a power generation technology that is gaining recognition as an environmentally friendly technology. While solar power can produce electricity with minimal pollution, its power generation efficiency is lower than that of other conventional power generation technologies due to uneven sunlight exposure to the ground caused by climate, weather, and various meteorological anomalies.

[0003] The core of solar power generation technology is how to collect and transmit the power generated by solar power generation devices called photovoltaic panels or solar panels without loss. In order to maximize the low power generation efficiency, it is important to increase the efficiency of communication between the various modules that are the main subjects of power generation.

[0004] Meanwhile, the power generated from the PV panel is converted and transmitted by a micro-inverter attached to the PV panel. However, the technology required for mass production of PV panels and the technology required for mass production of micro-inverters are different, so there is a tendency for companies to produce only PV panels and companies to produce only micro-inverters. However, if the PV panel and micro-inverter are produced by different companies, compatibility issues may arise. Therefore, after the user combines the PV panel and micro-inverter, he or she must manually input information about the PV module, including the PV panel, through an installer application running on the terminal, which is inconvenient. In addition, if the user makes a mistake in entering information about the PV panel into the terminal, the PV panel may not be recognized.

[0005] Figure 1 is a schematic diagram illustrating an example of inputting information about a PV panel through a user terminal during the process of installing a PV module.

[0006] FIG. 1 illustrates a conventional technology in which PV panels and microinverters are manufactured by different companies and combined, and an installer is executed through a user's terminal. Referring to FIG. 1, it can be seen that the user must directly input the manufacturer of the PV module, the model name of the PV module, the type of the PV module, and the power information of the PV module through the installer. If a process such as that in FIG. 1 can be omitted and automated, as described above, user convenience is increased and human error in the data input process can be minimized, and therefore the need for such technology arises.

[0007] The technical problem to be solved by the present invention is to provide a method for controlling information transmission and reception of an AC module including a PV panel and a system for implementing the method.

[0008] According to an embodiment of the present invention for solving the above technical problem, a method comprises the steps of: receiving first information from an AC combiner to which at least one AC module including a PV panel and a microinverter is connected; controlling input-induced information to be output on a display of a user terminal based on the reception of the first information; controlling transmission control information to be transmitted to the AC combiner, which controls second information to be transmitted from a microinverter of the AC module to the AC combiner based on an input corresponding to the input-induced information output to the user terminal; controlling the second information collected in the AC combiner to be transmitted to a cloud server; and receiving third information corresponding to the second information from the cloud server and controlling the third information to be output on the display.

[0009] According to another embodiment of the present invention for solving the above technical problem, a system for controlling information transmission and reception of an AC module including a PV panel, the system including an AC combiner, a cloud server, and a user terminal, wherein the AC combiner detects that at least one AC module including a PV panel and a micro-inverter is connected to generate first information, receives second information from a micro-inverter of the AC module through a control signal from the user terminal that has received the generated first information, and transmits the second information to the cloud server, the cloud server generates third information corresponding to the second information, and transmits the third information to the user terminal, and the user terminal generates the control signal in response to receiving the generated first information, and transmits the control signal to the AC combiner, and outputs the generated third information from the cloud server through a display.

[0010] According to the present invention, it is convenient for the user to not have to input information about the PV panel one by one.

[0011] In addition, according to the present invention, human error can be prevented by automating the act of a user having to input information one by one, and the time required to install a PV panel can be shortened compared to the conventional method.

[0012] Figure 1 is a schematic diagram illustrating an example of inputting information about a PV panel through a user terminal during the process of installing a PV module.

[0013] Figure 2 is a schematic diagram showing the entire system for implementing the method according to the present invention.

[0015] Figure 4 is a flowchart illustrating an example of a method according to the present invention.

[0016] FIG. 5 is a drawing exemplarily showing information about an AC module output on a display of a user terminal when the present invention is applied.

[0017] FIG. 6 is a drawing exemplarily showing total power production information of AC modules output on the display of a user terminal when the present invention is applied.

[0018] According to an embodiment of the present invention for solving the above technical problem, a method comprises: receiving first information from an AC combiner to which at least one AC module including a PV panel and a microinverter is connected; controlling input-induced information to be output on a display of a user terminal based on the reception of the first information; controlling transmission control information to be transmitted to the AC combiner, which controls second information to be transmitted from a microinverter of the AC module to the AC combiner when an input corresponding to the input-induced information output to the user terminal is received; controlling the second information collected in the AC combiner to be transmitted to a cloud server; and receiving third information corresponding to the second information from the cloud server and controlling the third information to be output on the display.

[0019] In the above method, the first information may be confirmation information generated when the AC module and the AC combiner are electrically connected.

[0020] In the above method, the input-induced information may be a smart button output through the display of the user terminal, and the input corresponding to the input-induced information may be a touch input to the smart button.

[0021] In the above method, the second information may be identification information of the microinverter.

[0022] In the above method, the third information may include identification information of the microinverter, identification information of the PV panel, and production power information of the PV panel.

[0023] In the above method, the step of controlling the second information to be transmitted to the cloud server may be such that when a preset number of AC modules are connected and the second information is accumulated for each connected AC module, the accumulated second information is transmitted to the cloud server.

[0024] In the above method, the step of controlling the second information to be transmitted to the cloud server may control the AC combiner to check the received second information at preset intervals and to transmit the checked second information to the cloud server in batches.

[0025] In the above method, the step of controlling the second information to be transmitted to the cloud server can control the AC combiner to transmit connection information for connecting to the cloud server based on the information input to the user terminal.

[0026] According to another embodiment of the present invention for solving the above technical problem, a system for controlling information transmission and reception of an AC module including a PV panel, the system including an AC combiner, a cloud server, and a user terminal, wherein the AC combiner detects that at least one AC module including a PV panel and a micro-inverter is connected to generate first information, receives second information from a micro-inverter of the AC module through a control signal from the user terminal that has received the generated first information, and transmits the second information to the cloud server, the cloud server generates third information corresponding to the second information, and transmits the third information to the user terminal, and the user terminal generates the control signal in response to receiving the generated first information, and transmits the control signal to the AC combiner, and outputs the generated third information from the cloud server through a display.

[0027] In the above system, the first information may be confirmation information generated when the AC module and the AC combiner are electrically connected.

[0028] In the above system, based on the first information received, input-induced information is controlled to be output on the display of the user terminal, and the input-induced information is a smart button output through the display of the user terminal, and the input corresponding to the input-induced information may be a touch input for the smart button.

[0029] In the above system, the second information may be identification information of the microinverter.

[0030] In the above system, the third information may include identification information of the microinverter, identification information of the PV panel, and power consumption information of the PV panel.

[0031] In the above system, the user terminal can control the accumulated second information to be transmitted to the cloud server when the AC modules are connected in a preset number and the second information is accumulated for each connected AC module.

[0032] In the above system, the user terminal can control the AC combiner to check the second information received at preset intervals and to transmit the checked second information in bulk to the cloud server.

[0033] In the above system, the user terminal can control the AC combiner to transmit connection information for connecting to the cloud server based on information entered into the user terminal.

[0034] One embodiment of the present invention can provide a computer-readable recording medium storing a program for executing the above method.

[0035] The present invention is capable of various modifications and embodiments. Specific embodiments are illustrated in the drawings and described in detail in the detailed description. The effects and features of the present invention, as well as the methods for achieving them, will become clearer with reference to the embodiments described in detail below, along with the drawings. However, the present invention is not limited to the embodiments disclosed below and can be implemented in various forms.

[0036] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, identical or corresponding components are given the same drawing reference numerals, and redundant descriptions thereof will be omitted.

[0037] In the following examples, the terms first, second, etc. are not used in a limiting sense, but are used for the purpose of distinguishing one component from another.

[0038] In the examples below, singular expressions include plural expressions unless the context clearly indicates otherwise.

[0039] In the following examples, terms such as “include” or “have” mean that a feature or component described in the specification is present, and do not preclude the possibility that one or more other features or components may be added.

[0040] In some embodiments, where the implementation is otherwise feasible, a particular process sequence may be performed in a different order than described. For example, two processes described in succession may be performed substantially simultaneously, or in a reverse order from the described order.

[0041] Figure 2 is a schematic diagram showing the entire system for implementing the method according to the present invention.

[0042] Referring to FIG. 2, it can be seen that the entire system (1) according to one embodiment of the present invention is connected to an AC combiner (13), a user terminal (15), and a cloud server (17) via a communication network (20). In addition, although not shown in FIG. 2, the AC combiner (13) is connected to at least one AC module (11-1, 11-2, ... 11-n) via various wired or wireless communication networks. As an example, the AC module and the AC combiner (13) can communicate with each other via PLC communication.

[0043] First, in the present invention, an AC module refers to a module that physically includes a photovoltaic panel (PV panel) and a micro-inverter. For the sake of the intuitiveness of the drawing, the PV panel and micro-inverter included in each AC module are considered to be omitted in FIG. 2. In addition, a PV panel can convert incident sunlight into direct current (DC) power, and in the present invention, a PV panel is considered a broad concept that further includes a separate angle adjustment mechanism to increase light collection efficiency. A micro-inverter is electrically connected to a PV panel and can convert DC power converted by the PV panel into AC power.

[0044] In the present invention, the PV panel and the microconverter are referred to as an AC module, which is a single unit. As illustrated in Fig. 2, there may be at least one AC module, and at least one AC module (11-1, 11-2, ... 11-n) is electrically connected to the AC combiner (13) via a cable and can communicate with the AC combiner (13). In Fig. 2, the number of AC modules is limited to n, but in the present invention, the number of AC modules is not limited to a specific number, and therefore, depending on the embodiment, the number of AC modules may be less or more than n.

[0045] In the present invention, the serial number of the PV panel and the serial number of the microinverter can be respectively confirmed and managed as a pair. That is, when the serial numbers of the PV panel and the microinverter corresponding to the PV panel are respectively confirmed during the production process of the AC module, the confirmed pair of serial numbers can be stored and managed in the cloud server (17) through a predetermined terminal through manual input by the user or automatic input by the module production machine.

[0046] The AC combiner (13) can perform a function of receiving and storing AC power generated from at least one AC module, or communicating with the AC module (11-1) through various communications. That is, the AC combiner (13) functions as a combiner that collects and combines information transmitted from a plurality of AC modules (11-1, 11-3, ... 11-n), and, as described below, can operate by receiving a control signal from a user terminal (15) and transmitting and receiving predetermined information according to the received control signal.

[0047] The user terminal (15) is a terminal used by a user, and refers to an electronic device equipped with a communication module capable of communicating with the AC combiner (13) and the cloud server (17). The user terminal (15) refers to a smart device that includes an input device that receives user input, an output device (display) that visually outputs the input of the user terminal (15) or the processing result of the terminal, and a communication module capable of communicating with an external device. Therefore, as long as it includes only the input device, output device, and communication module described above, there is no limitation in size or type. For example, in FIG. 2, the user terminal (15) is illustrated in the form of a smartphone, but the user terminal (15) may also be a PC, laptop, netbook, etc. capable of communicating with the AC combiner (13) and the cloud server (17).

[0048] A cloud server (17) refers to a server that can selectively perform communication with an external device accessing the communication network (20) based on approved access information. The cloud server (17) is a device that can quickly and accurately perform the operations required to implement the method according to the present invention, and, depending on the embodiment, may physically or logically include an AI model for accurately performing the required operations.

[0049] The communication network (20) performs the function of electrically connecting the AC combiner (13), user terminal (15), and cloud server (17), which are components of the overall system (1) illustrated in FIG. 2, and may include various wired and wireless communication networks such as a data network, a mobile communication network, and the Internet. In particular, the communication network (170) in the present invention includes not only the currently used mobile communication network, but also the old-generation mobile communication network that has already been used and then discarded, and the next-generation mobile communication network whose infrastructure is scheduled to be built and used in the future, and thus may be one of GSM (Global System for Mobile communications), CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), CDMA 2000, LTE (Long Term Evolution), LTE-A (Long Term Evolution Advanced), 5G (5-Generation), and the 6G mobile communication network scheduled for service in 2030.

[0050] The communication network (20) is a network implemented by an ISP (Internet Service Provider), and therefore is omitted from the overall system (1) of Fig. 2, but may be implemented by an ISP base station server and communication cables for physically and logically implementing the communication network (20). However, in the process of initiating communication between the AC combiner (13) and the user terminal (15), the communication counterpart can be confirmed and recognized through short-range communication between the AC combiner (13) and the user terminal (15), and in this case, the communication network (20) may be a concept that temporarily limits the wide-area communication network provided by the ISP.

[0051] Below, an embodiment of the present invention implemented by data transmission and reception of each component of the aforementioned overall system (1) will be specifically described.

[0052] First, when an AC module (11-1) including a PV panel and a micro-inverter is connected to an AC combiner (13), the user terminal (15) can communicate with the AC combiner (13) and receive first information from the AC combiner (13). Here, the first information is a type of confirmation information generated when the AC module (11-1) and the AC combiner (13) are electrically connected, and is considered to be information transmitted from the AC combiner (13) to the user terminal when the AC combiner (13) and the user terminal (15) can communicate after the connection portion of the AC module (11-1) and the AC combiner (13) are interlocked and connected to each other. The user can recognize that at least one AC module is connected to the AC combiner (13) through the user terminal (15) that has received the first information.

[0053] Next, when the first information is transmitted from the AC combiner (13), the app installed on the user terminal (15) can control input-inducing information to be output on the display of the user terminal (15) based on the first information being received. Here, the input-inducing information refers to information that has the characteristic of causing the user to confirm specific information through the user terminal (15) and inducing subsequent input accordingly, and may mainly be visual information, but is not limited thereto, and may be information in the form of auditory or tactile (vibration). For example, the input-inducing information may be a smart button output through the display of the user terminal (15), and the input corresponding to the input-inducing information may be a touch input for the smart button.

[0054] When a user inputs corresponding to the input-induced information through a user terminal (15), the AC module (11-1) and the AC combiner (13) are connected not only in hardware but also in software to operate normally. In other words, the input corresponding to the input-induced information can be understood as a concept of approval for the AC module (11-1) most recently connected to the AC combiner (13).

[0055] When an input corresponding to input-induced information is input to the user terminal (15), the AC combiner (13) can transmit second information from the microinverter included in the AC module (11-1) to the AC combiner (13). That is, the AC combiner (13) can receive information that an input corresponding to input-induced information has been input from the user terminal (15), and thereafter, request the AC module (11-1) to transmit second information from the AC module (11-1).

[0056] At this time, the second information transmitted from the AC module (11-1) to the AC combiner (13) is the identification information of the microinverter, which is a broad concept including the serial number described above. In other words, the identification information of the microinverter may be a serial number, or a character string including various alphabets and symbols (or a model name composed of a character string).

[0057] The app installed on the user terminal (15) can control the AC combiner (13) to transmit the second information received by the AC combiner (13) to the cloud server (17) when the AC combiner (13) receives the second information from the AC module (11-1). More specifically, if the settings for communication between the user terminal (15) and the cloud server (17) are not made in advance, the AC combiner (13) cannot communicate with the cloud server (17). However, after receiving a key and login information for accessing the cloud server (17) through various settings processed in an app such as an installer installed on the user terminal (15), free communication is possible with the cloud server (17) through the communication network (20). As described above, when the user inputs a smart button output through the display of the user terminal (15), communication between the AC combiner (13) and the cloud server (17) can be initiated, and various other methods may also be used. Additionally, the communication channel established between the AC combiner (13) and the cloud server (17) remains valid until it is separately terminated.

[0058] The cloud server (17) receives the second information from the AC combiner (13), and then searches the database (not shown) of the cloud server (17) to detect the identification information of the PV panel included in the AC module (11-1), the identification information of the microinverter, and the production power information of the PV panel, and transmits the detected identification information of the PV panel, the identification information of the microinverter, and the production power information of the PV panel to the user terminal (15) via the communication network (20). The identification information of the PV panel, the identification information of the microinverter, and the production power information of the PV panel correspond to the first information and the second information described above and may be collectively referred to as third information.

[0059] As an example, the user terminal (15) can control the AC combiner (13) so that when a preset number of AC modules are connected and second information is accumulated for each connected AC module, the accumulated second information is transmitted to the cloud server (17). More specifically, when the user designates the number of second information to be accumulated in the AC combiner (13) through an app installed in the user terminal (15), the AC combiner (13) transmits the accumulated second information to the cloud server (17) only when the second information is accumulated to the designated number of second information. For example, if the user inputs an accumulation limit of the second information into the user terminal (15), when five AC modules are connected to the AC combiner (13) and second information is accumulated for each of the five AC modules, the second information for the five AC modules can be transmitted to the cloud server (17). According to this embodiment, the number of data transmissions and receptions between the AC combiner (13) and the cloud server (17) is significantly reduced, which is advantageous in terms of resource management of the AC combiner (13) and the cloud server (17).

[0060] As another embodiment, the user terminal (15) can control the AC combiner (13) to check the received second information at preset intervals and to collectively transmit the confirmed second information to the cloud server (17). More specifically, when the user sets the second information confirmation cycle of the AC combiner (13) through an app installed on the user terminal (15), the AC combiner (13) checks the second information at preset intervals and transmits the second information to the cloud server (17). For example, if the second information confirmation cycle is set to 10 minutes, the AC combiner (13) checks for updated second information every 10 minutes and transmits the updated second information to the cloud server (17). According to the present embodiment, the cycle at which the cloud server (17) checks the second information and transmits third information corresponding to the second information to the user terminal (15) is constant, so predictability can be secured and consistency can be achieved in data management.

[0061] As another example, connection information for connecting to a cloud server (17) may be transmitted to the AC combiner (13) based on information entered into the user terminal (15). Here, the connection information means information for activating a communication channel between the AC combiner (13) and the cloud server (17), and once a communication channel between the AC combiner (13) and the cloud server (17) is established once by the user, communication between the AC combiner (13) and the cloud server (17) may be maintained thereafter without a separate command.

[0062] FIG. 3 is a diagram schematically illustrating a user terminal and a management app for the user terminal according to one embodiment of the present invention.

[0063] Hereinafter, the description will be given with reference to Fig. 2.

[0064] In FIG. 3, the user terminal (15) illustrated together with the management app (300) refers to an electronic device equipped with a display (16) for displaying visual data and an interface (not illustrated) for receiving data from a user. Referring to FIG. 3, the user terminal (15) is illustrated in the form of a smartphone, but the user terminal (15) when the present invention is implemented is not limited to a smartphone, and may include all portable terminals such as tablet personal computers (Tablet PCs) and netbooks.

[0065] The management app (300) of FIG. 3 is not a physical device, but rather a logical device representing an intangible application installed on a user terminal (15). Although it is illustrated as being included in the user terminal (15) in FIG. 3, when the management app (300) is actually implemented on the user terminal (15), it can be implemented in a form in which a set of scripts composed of various commands are integrated into an executable program and installed on the user terminal (15). That is, the management app (300) operates in a form in which it controls the content displayed on the display (16) of the user terminal (15).

[0066] The management app (300) in FIG. 3 only illustrates components intended to highlight the features of an embodiment of the present invention. Therefore, those skilled in the art will readily appreciate that, in embodiments other than the one illustrated in FIG. 3, other general-purpose components may be included in addition to the components illustrated in FIG. 3.

[0067] Referring to FIG. 3, it can be seen that the management app (300) includes a communication unit (310), a data processing unit (330), a database (350), and a display control unit (370).

[0068] The communication unit (310) can control communication with an external device. Specifically, the communication unit (310) can be understood as a logical module for the user terminal (15) to communicate with the AC combiner (13) and the cloud server (17) through the communication network (20) of FIG. 2. The communication unit (310) can perform a function of receiving first information from the AC combiner (13) and transmitting it to the data processing unit (330), transmitting connection information for establishing a communication channel between the AC combiner (13) and the cloud server (17) to the AC combiner (13), or receiving third information from the cloud server (17) and transmitting it to the data processing unit (330). That is, the communication unit (241) can control the physical communication module of the user terminal (15) to operate in a limited manner according to a predefined command.

[0069] The data processing unit (330) can process the overall process required to implement the method according to the present invention. The data processing unit (330) is a physical device, a processor, implemented logically (script), and refers to a logical module designed based on at least one of ASICs (application specific integrated circuits), DSPs (digital signal processors), DSPDs (digital signal processing devices), PLDs (programmable logic devices), FPGAs (field programmable gate arrays), controllers, micro-controllers, microprocessors, and other electrical units for performing functions.

[0070] As an example, the data processing unit (330) may receive first information from an AC combiner (13) to which at least one AC module (11) including a PV panel and a micro-inverter is connected, and control input-induced information to be output on the display of a user terminal (15) based on the reception of the first information, and when an input corresponding to the input-induced information is received at the user terminal (15), control transmission control information to be transmitted to the AC combiner (13) so that second information is transmitted from the micro-inverter of the AC module (11) to the AC combiner (13), control second information collected in the AC combiner (13) to be transmitted to a cloud server (17), receive third information corresponding to the second information from the cloud server (17), and control the third information to be output on the display.

[0071] The database (350) stores various types of information in conjunction with hardware such as memory physically included in the user terminal (15), and can control the transmission of stored information when requested by the data processing unit (330). In addition, the database (350) can store first information, second information, third information, input-induced information, and connection information collected during the data processing process by the data processing unit (330).

[0072] The display control unit (370) performs a function of controlling the output of information determined to be output on the display (16) of the user terminal (15) through a series of processes. Here, it has already been explained that the determined information can be third information.

[0073] The functions of the management app (300) in Fig. 2 are explained by sub-module in Fig. 3 as follows.

[0074] The communication unit (310) can receive first information from an AC combiner (13) to which at least one AC module (11) including a PV panel and a microinverter is connected.

[0075] The data processing unit (330) can control input-induced information to be output to the display (16) of the user terminal (15) based on the first information received.

[0076] When an input corresponding to input-induced information is received at the user terminal (15), the data processing unit (330) can control the communication unit (310) to transmit transmission control information to the AC combiner (13) for controlling the transmission of second information from the micro-inverter of the AC module to the AC combiner (13). As another example of step S450, the data processing unit (330) can control the communication unit (310) to transmit transmission control information to the AC module for controlling the transmission of second information from the micro-inverter of the AC module to the user terminal (15) by directly communicating with the AC module without going through the AC combiner (13).

[0077] The data processing unit (330) can control the second information collected in the AC combiner (13) to be transmitted to the cloud server (17).

[0078] The communication unit (310) receives third information corresponding to the second information from the cloud server (17), and the display control unit (370) can control the third information to be output to the display.

[0079] Figure 4 is a flowchart illustrating an example of a method according to the present invention.

[0080] The method according to FIG. 4 can be implemented by the user terminal (15) described in FIGS. 2 and 3 and the management app (300) installed on the user terminal (15), and therefore, the method will be described below with reference to FIGS. 2 and 3.

[0081] The communication unit (310) can receive first information from an AC combiner (13) to which at least one AC module (11) including a PV panel and a microinverter is connected (S410).

[0082] The data processing unit (330) can control input-induced information to be output to the display (16) of the user terminal (15) based on the first information received (S430).

[0083] The data processing unit (330) can control the communication unit (310) to transmit transmission control information to the AC combiner (13) to control second information to be transmitted from the microinverter of the AC module to the AC combiner (13) when an input corresponding to input-induced information is received at the user terminal (15) (S450).

[0084] The data processing unit (330) can control the second information collected in the AC combiner (13) to be transmitted to the cloud server (17) (S470).

[0085] The communication unit (310) receives third information corresponding to the second information from the cloud server (17), and the display control unit (370) can control the third information to be output to the display (S490).
