Description

Technical Field

[0001] The present invention relates to the field of power systems, and more particularly to devices for energy storage and supply, which may also be referred to as power stations, including inverters and batteries. These devices are generally used to support self-consumption solar energy systems or to replace or be used in combination with existing fuel generators. Because of the AC input port for backup power that can be used with the grid or fuel generators, the ideal inverter to be integrated into the present invention is preferably a single-phase, hybrid inverter including a charge controller.

[0002] The object of the present invention is to provide a new configuration of the above-mentioned elements (i.e. the inverter and the battery) designed to maintain their separability in order to use them in two different modes. Firstly, a portable operating mode intended for use in isolated locations, wherein the two elements are arranged relative to each other, in particular when they are located in a transport element such as a cart. Secondly, a fixed mode within an electrical installation, wherein both elements can be independently mounted on a wall, occupying a minimum of space, and connected via a circuit board. Background Art

[0003] The inverter and the battery and photovoltaic panel are the three main components of the solar self-consumption generator. The inverter converts the DC power from the photovoltaic panel or battery into AC power for powering the load of the device, while the battery can store the excess power generation for use when the solar radiation is no longer sufficient to power the load. The inverter type mentioned above (single-phase hybrid inverter with integrated charge controller) has a CC input port for the photovoltaic panel, a CC input port and output port for the battery, an AC output port for powering the load of the device, and a CA input port for connecting to the grid when located in a fixed private device and connecting to a fuel generator when located in an isolated location to ensure uninterrupted power supply.

[0004] A portable solar system includes at least the three elements mentioned above: an inverter, a battery, and a portable solar panel. In recent years, portable solar systems have been rapidly developed for outdoor activities in areas without access to the power grid, replacing or mixing with traditional fuel generators. For these situations, several solutions are currently known: the above-mentioned elements (inverter and battery) are designed in a compact unit in a cubic format.

[0005] The main drawback of these compact solutions is that, at high power levels, their size and weight make it difficult to achieve portability, which is the essence of these systems. Another drawback is that these solutions can only be used in portable mode and cannot be integrated into personal devices.

[0006] In solar self-consumption systems for private installations, batteries are used for storage, while arrays of photovoltaic panels are permanently installed on roofs, facades, gardens and terraces. For these systems, the current solutions are always fixed, and the two elements mentioned (inverter and battery) are usually installed separately in a position close to the circuit board of the electrical device in which they are integrated. A considerable number of inverters are designed to be mounted on the wall, while the batteries, due to their weight and volume, are either installed on the floor below the inverter or in an adjacent room, when installed in an adjacent room, their excessive volume is not a problem. A known solution in the prior art is the Powerwall solution of TESLA, in which the battery is designed in a flat form, its depth is reduced, but the height and width dimensions are greatly increased. In this way, the unit can be mounted in a wall-mounted mode, thereby reducing the volume protruding into the interior of the room.

[0007] The main disadvantage of these private installation solutions is that they are fixed and cannot be disassembled by the user to occasionally use them in a portable mode as power stations in remote areas. Summary of the invention

[0008] The present invention aims to address at least one of the aforementioned disadvantages.

[0009] An object of the present invention is to provide a battery and inverter arrangement that facilitates dual use. Specifically, the arrangement can be operated in a portable mode and a fixed mode, and can be easily converted between these two modes. In addition, the present invention is also intended to overcome the portability challenges caused by the excessive weight of the battery and inverter, thereby enabling independent transportation and better operation of the equipment. The present invention also addresses the need to minimize the volume of the battery and inverter protruding into the room when used in a fixed operating mode and connected to existing electrical installations. It is worth noting that traditional inverters and batteries are relatively wide and are generally not suitable for wall mounting in residential, commercial and business spaces.

[0010] More specifically, a first aspect of the invention relates to a device for energy storage and supply, possibly marketed as a power station. This device introduces several new components and a set of adaptive elements for a hybrid inverter and at least one battery module. These modifications facilitate their separation and allow them to be used in two different modes: a portable mode for use in an isolated environment, in which the inverter and the at least one battery module are relatively fixed, preferably fixed to a transport element such as a cart; and a fixed mode for private electrical installations, in which both components are mounted on a wall close to the circuit board of the electrical installation.

[0011] Throughout the specification, if not explicitly mentioned, it should be understood that a battery includes at least one battery module.

[0012] Furthermore, within the meaning of the present invention, fasteners as referred to in the context of this specification are essentially devices or mechanisms that enable the connection and removal of key components, in this case the inverter and battery. Fasteners may include a variety of designs and mechanisms, such as clips, clamps, couplings, brackets, hooks, and even magnetic, adhesive or Velcro solutions, as long as their main purpose is to securely connect these components together while allowing them to be easily separated when required. The exact form or structure of these fasteners is not strictly defined, but may vary greatly depending on the specific needs and limitations of the application, the materials used, weight considerations and other factors. It will be clearly understood by those skilled in the art that any equivalent device that can achieve the basic function of connecting and removing these components falls within the scope and spirit of the present invention.

[0013] According to a first aspect of the present invention, there is provided a device for energy storage and supply, comprising: an inverter and at least one battery module, wherein the inverter and the at least one battery module can be connected and removed to determine:

[0014] - a fixed operating mode in which the inverter and the at least one battery module are not connected to each other, wherein the inverter is configured to be connected to an electrical device for own use;

[0015] a portable operating mode in which the inverter and the at least one battery module are connected to each other, wherein this mode facilitates transportation, in particular by electrically disconnecting and physically removing the inverter from the electrical device,

[0016] Wherein, the at least one battery module includes a first battery fastener that can be attached to an inverter fastener included in the inverter, wherein the first battery fastener and the inverter fastener are configured to be used in the portable mode in which the inverter is attached to the at least one battery module.

[0017] The first battery fastener described above is preferably a front battery fastener, but those skilled in the art may conceive of alternative configurations or arrangements to achieve similar solutions, all of which are in accordance with the spirit of the present invention. Similarly, although the inverter fastener described in the preferred embodiment of the present invention may be considered as a rear fastener, other configurations or arrangements consistent with the purpose and spirit of the present invention can be directly envisioned, and therefore, the present invention is not limited to a rear fastener or a front battery fastener.

[0018] In some embodiments, the device or power station further comprises an inverter wall fastener for attaching to a wall or any vertical surface during the fixed operation mode, wherein the inverter fastener can also be attached to the inverter wall fastener. It should be noted that in this embodiment, the inverter fastener can be attached to the at least one battery and can also be attached to the inverter wall fastener.

[0019] Alternatively, the inverter may further include a second inverter fastener attachable to the inverter wall fastener, so the aforementioned inverter fastener for attaching to the battery fastener is different from the second inverter fastener for wall-mounting connection described herein.

[0020] In the context of the present invention, the term "wall" is intended to broadly refer to any surface or structural element that can serve as a support for the device elements. It is worth noting that it is not limited to traditional building walls, but can also cover any vertical support structure that can accommodate fasteners and equipment. For example, it may include special mounting plates, structural columns, pillars, partitions, and even specially designed independent frames or racks. Essentially, any surface or structure that provides stability and is suitable for mounting components of the device can be used as a "wall" in the context of the present invention.

[0021] In some embodiments, the device further comprises battery wall fasteners for attaching to a wall or any vertical surface during the fixed operating mode. Here, the battery modules or at least one of them may be provided with second battery fasteners capable of engaging with the battery wall fasteners. The fasteners are specifically designed for the fixed operating mode, in particular when the battery modules are electrically connected but not physically connected to the inverter. Thus, in the fixed operating mode, the battery modules may be mounted on the wall using these second battery fasteners.

[0022] The second battery fastener may be, but is not limited to, a rear fastener, i.e., a fastener disposed on the rear surface of the battery, and the first battery fastener may be a front battery fastener. However, those skilled in the art may conceive of other configurations and solutions, which all belong to the spirit and purpose of the present invention.

[0023] Alternatively, the first battery fastener may be attached to the battery wall fastener. In this configuration, the first battery fastener may be connected to the inverter fastener and the wall fastener, thereby eliminating the need for a second battery fastener.

[0024] In some embodiments, the second battery fastener may also be attached to a transport device, wherein the transport device includes a transport fastener connectable to the second battery fastener. This facilitates easy transport during the portable operating mode.

[0025] Optionally, the transport device comprises a cart, wherein the cart comprises a plurality of wheels and a frame; the frame being provided with a transport fastener attachable to the second fastener of the at least one battery module.

[0026] In some embodiments, the inverter can be a single-phase model preferably integrated with a flat form, the depth of which is preferably less than 12 cm, so that its width and height are significantly reduced. The same format is also used for the design of the battery, the maximum depth of which is limited to 15 cm. In this way, when used in a wall-mounted configuration hanging on the wall, the two volumes generated above extend into the room to the minimum extent, and the volumes are also as compact as possible for use in a portable mode, in which the inverter is placed in front of the battery and can be coupled to a transport element such as a cart.

[0027] The flat format mentioned above allows the placement of a handle in the central part of the upper surface of the two elements (battery and inverter), which allows the user to be closer to the center of gravity of each element and facilitates independent operation using only one arm and keeping the body always upright, thus avoiding the risk of back injuries. Despite the heavy weight of both elements (especially the battery), the presence of the upper handle solves the need to handle the two elements, making it possible to convert between the two operating modes mentioned above (fixed mode and portable mode) and to use them in situations where there are obstacles that make it difficult to use the cart in portable mode (floor does not allow rolling, there are steps, it is necessary to load them into the trunk of a car, etc.), which makes it more practical when taking them out of the cart and handling them separately, so it is best to have both of the above handles.

[0028] In some embodiments, the battery is a modular battery and includes first and second fasteners, for example, complementary front and rear fasteners, such that several battery modules can be connected together one after another for use in a portable mode.

[0029] The second battery fastener (or rear battery fastener) also allows the battery to be fixed to a wall for use in wall-mounted mode, or attached to the structure or frame of a transport device (e.g., a cart) for use in portable mode. In both cases, the battery is attached to the wall or the structure of the aforementioned transport device by means of complementary fasteners or transport fasteners. The front fastener of the battery also allows the inverter to be coupled in the portable mode.

[0030] In some embodiments, the two side junction boxes contain connectors connected to the battery poles, preferably protected by magnetothermal circuit breakers, which solves the modularity of the battery in both operating modes (wall-mounted and portable). In portable mode, modulation can be achieved by connecting the battery modules together one by one and connecting them in parallel with cables through the junction box on the same side. In wall-mounted mode, the battery modules can be attached to the wall adjacent to each other, and the connection of the battery modules is completed through adjacent junction boxes via the same cable. In both modes, the inverter can be connected to the first battery module in series through the junction box. Moving the connector and its protection device to the external box can also greatly reduce the volume of the battery box containing the battery cells.

[0031] The cart as a transport device can be composed of a combination of rear wheels with a simple front support or of rear wheels with front wheels. The wheels can be fixed or rotating, or a combination of fixed rear wheels and rotating front wheels. The cart structure can also include a support platform and a rear vertical frame, the rear vertical frame including complementary fasteners for coupling the battery. The frame can include at least two vertical tubes with handles attached to the upper part, the handles including two vertical elements and an upper horizontal gripping element. Depending on the type of coupling with the frame, the handles can be fixed, articulated or retractable. In a fixed coupling, the vertical tubes of the frame and the vertical tubes of the handle are continuous and can form a single element. In the case of articulation, the lower end of the vertical handle element is connected to the upper end of the frame by a horizontal pivot joint. In the retractable case, the vertical handle element is folded into the frame element.

[0032] Alternatively, the battery and cart may be integrated into a single element, wherein the battery includes wheels on its base and a retractable handle that folds into a channel on the rear cover of the battery. The front fasteners may still be present for coupling the inverter to the front of the battery in portable mode, while the rear fasteners, which are also present, are used only to couple the battery to the integrated handle and wheels included in the battery and to the complementary wall fasteners in wall-mounted mode.

[0033] In some embodiments, the inverter is mounted on a plate (e.g., an aluminum plate) of the box near the bottom, the function of which is to integrate the protection of the inverter input and output, in particular their respective connectors, to allow the inverter to be kept detachable. The solar panels can be connected to the inverter via direct current (DC) connectors integrated in the box, and the connection is protected from short circuits and overloads by fuses. The alternating current (AC) output of the inverter is protected from shunting by a differential circuit breaker and from short circuits by a magnetic thermal circuit breaker; the live socket is female and integrated in the box. The AC input of the grid or fuel generator can also be carried out through a socket. In this case, the socket is male and integrated in the box. The battery can be protected by a fuse or a thermal magnetic circuit breaker integrated in the battery box.

[0034] It is worth noting that the junction box mentioned above allows for quick and safe disconnection and reconnection of electrical connections, thus facilitating transitions between modes. For example, solar panels or grid power can be connected or disconnected via the sockets integrated into the box. Similarly, AC power from the grid or fuel generator can be easily disconnected.

[0035] The DC connectors of the inverter and the battery can be externally connected to the junction box by extending the two-core output cables of each inverter and battery and using the two male and female parts of a single DC connector at their ends. The extension length of the two cables must be sufficient to cover the maximum separation of the two elements at the wall position. Optionally, in order to avoid that both cables are hung on two elements, the two-core output cable of the inverter can be inserted into the box and its connector is also integrated therein; the same operation can be performed on the battery, replacing its cable with another connector integrated in the battery box. In this embodiment, a separate two-core cable section is used, the end of which has a complementary connector, which is connected to the aforementioned connector integrated in the junction box and battery, and it should be long enough to cover the maximum separation of the aforementioned integrated connector that occurs in the wall-mounted position.

[0036] There may be a rear fastener or second inverter fastener on the back of the plate to which the inverter is mounted. This feature allows the inverter to be connected to the inverter wall fastener for use in a wall-mounted or fixed operating mode. Alternatively, it allows it to be attached to the aforementioned front battery fastener for use in a portable mode.

[0037] In order to integrate the device of the invention (often also called a power station) into a private installation, it may be necessary to cut the conductors, phase and neutral, at the output of the differential circuit breaker of the circuit board, or at the output of the magnetothermal circuit breaker of the circuit, as well as the corresponding ground conductor, and extend their ends through internal or external conduits to the vicinity of the inverter and its terminal box located on the wall. Then, on the one hand, a female socket is coupled to the live end of the differential or magnetothermal circuit breaker from the circuit board, and to the ground end connected to the device electrode, which female socket can be connected to the AC input male connector of the terminal box; on the other hand, another male socket is coupled to the non-live end of the power supply or the ground end of the circuit, or the non-live end of the selected individual circuit, which male socket can be connected to the AC output female connector of the terminal box. Whether the output cut-off in the circuit board is selected from the differential circuit breaker or the magnetothermal circuit breaker of one of the circuits, depends on the power of the inverter of the power station. For inverters with a power higher than the agreed power, the cut-off can be made at the output of the differential switch. For low power inverters, integration can be done at the circuit level, always choosing those designed to handle higher power than the inverter in question can handle.

[0038] A second aspect of the present invention relates to a portable energy storage and supply system, wherein the system comprises the device according to any of the above embodiments, and further comprises:

[0039] At least one energy consuming device is coupled to the device in the portable mode of operation, wherein the energy consuming device utilizes energy from the at least one battery module.

[0040] The energy consuming device may be any appliance connected to the device to consume battery energy, such as a mobile phone, a heater or any appliance or device requiring energy stored in the battery of the device, that is, the device acts as a power station in portable mode.

[0041] In some embodiments, the system further comprises at least one power generation device configured to charge one or more battery modules, and in particular, the power generation device is at least a photovoltaic panel and / or a generator set.

[0042] A third aspect of the present invention relates to a method comprising:

[0043] Providing an inverter and at least one battery module that can be completely disassembled and connected;

[0044] connecting the inverter to an electrical device for self-consumption, wherein the inverter and the at least one battery module are not connected to each other;

[0045] The inverter is switched to a portable operating mode for transportation by connecting the inverter and the at least one battery module and disconnecting the inverter from the electrical device.

[0046] Preferably, the method further comprises:

[0047] providing a plurality of battery modules, wherein each battery module is connectable to another battery module;

[0048] connecting the plurality of battery modules one by one along a transverse axis, thereby stacking the plurality of batteries for transportation; and

[0049] The plurality of battery modules are attached to the inverter by attaching one of the distal or proximal battery modules of the stacked plurality of battery modules to the inverter. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] Considering the aforementioned figures and their corresponding numbers, exemplary and non-limiting embodiments of the present invention are described herein. In some embodiments, the design parameters of the device can be customized for a 24V, 2500W hybrid inverter (1) based on cylindrical LiFePO4 batteries and two 24V 100Ah battery modules (2). This configuration exemplifies a suitable solution for enabling the power station to adapt to the output of a 15A magnetothermal circuit breaker (5.8) protection circuit for self-consumption private electrical installations.

[0059] Figure 1a and Figure 1b The front view and rear view of an inverter (1) mounted on an aluminum inverter back plate (1.1) with a junction box (1.4) coupled to the bottom are shown. The junction box (1.4) integrates all protection devices and connectors of the inverter input and output ports, as well as an inverter connector (1.5) independent of the junction box (1.4) for the battery located at the end of the double-core cable.

[0060] like Figure 1a and Figure 1b As shown, the inverter (1) is designed in a flat form with a minimum depth dimension compared to its width and height for use in a wall-mounted mode, i.e., a fixed operating mode. The maximum depth is limited to 10 cm, and the maximum width and height are 30 cm and 45 cm respectively. The dimensions of the junction box (1.4) conform to this format, maintaining a similar depth while extending its width to match the width of the inverter (1). The reduced depth format of the inverter (1) allows the inverter handle (1.2) to be accommodated in the central part of the upper surface, allowing the user to easily operate it with only one arm and allowing them to always maintain an upright posture, thereby minimizing the risk of back injuries.

[0061] The inverter fasteners (1.3) are located on the back of the plate, allowing the inverter (1) to be mounted in two operating modes: a portable mode mounted on a cart (3.2) and a wall-mounted mode mounted on a wall (4.1). The fastener type shown in this preferred embodiment consists of four sections of tongue and groove guides, which allow the fasteners to be fastened along a small sliding portion of the female part of the inverter (1) to four complementary male fasteners located on the wall (4.3) or the front of the battery (2.1). The inverter (1) is supported on the wall by a bracket (4.5).

[0062] The inverter fasteners (1.3) are located on the back of the plate, allowing the inverter (1) to be mounted in two operating modes: a portable mode mounted on a cart (3.2) and a wall-mounted mode mounted on a wall (4.1). The fastener type shown in this preferred embodiment consists of four sections of tongue and groove guides, which allow the fasteners to be fastened along a small sliding portion of the female part of the inverter (1) to four complementary male fasteners located on the wall (4.3) or the front of the battery (2.1). The inverter (1) is supported on the wall by a bracket (4.5).

[0063] The inverter fastener (1.3) is located on the back of the plate, allowing the inverter (1) to be installed in two operating modes: a portable mode mounted on a transport device (3.2) (especially a cart) and a wall-mounted mode mounted on a wall. The type of fastener shown in the preferred embodiment includes four sections of tongue and groove guides. These guides allow the fastener to move along a small sliding part of the fastener of the female part of the inverter (1), while four complementary male fasteners are located on the inverter wall fastener (4.3) or the first battery fastener (2.1). The support of the inverter (1) on the wall is achieved by a battery wall fastener (4.4) materialized as a bracket (4.5).

[0064] Figure 2a and Figure 2bThe front view and back view of the battery module (2) are shown respectively. The battery module (2) has a first fastener or front battery fastener (2.1) (which can be a male fastener) and a second fastener or rear battery fastener (2.2) (which can be a female fastener), and also includes a top battery handle (2.3) and two side battery junction boxes (2.4) for connecting to an inverter (1) or another battery module (2) via a cable. The four front battery fasteners (2.1) can fasten the inverter (1) or another battery module in portable mode. The rear battery fastener (2.2) is composed of four sections of tongue and groove rails, so that the battery module (2) is fixed to the wall by the battery wall fastener (4.4) for wall hanging mode, or fixed to the structure of a cart or another battery module for portable mode. To this end, in this case, four complementary male fasteners are used to fix to the battery wall fastener (4.4) or the transport fastener (3.3). Each battery module (2) is supported on the wall by a bracket (4.6).

[0065] Like the inverter (1), the battery module (2) also adopts a flat design, with its depth reduced relative to the width and height to facilitate use in a wall-mounted operation mode or a fixed operation mode. The maximum depth is limited to 15 cm, while the maximum width and height are set to 45 cm and 60 cm respectively. These dimensions enable the battery handle (2.3) to be placed in the center of its upper surface. This positioning facilitates single-arm operation of the battery module (2), allowing the user to always maintain an upright posture, thereby minimizing the risk of back injuries.

[0066] Figure 5a and Figure 5b An embodiment of a connector and a protection box is shown, showing a schematic diagram of its features. More specifically, the solar panel can be connected to the inverter (1) via a DC input port (5.1) having two conductors and protected against overload and short circuit by corresponding fuses or circuit breakers (5.4). An Anderson type DC connector (5.5) for connecting a two-core cable of the solar panel is integrated into the junction box (1.4). Depending on the type and power of the panel, a varistor may also be included to protect the inverter (1) from overvoltages caused by high voltage transients caused by lightning strikes.

[0067] The AC outlet (5.2) of the inverter (1) has three conductors (phase, neutral and ground), which are realized by a female socket (5.6) integrated in the terminal box (1.4). Since protection independent of private devices is usually required, it is connected through its own differential circuit breaker (5.7) to prevent current shunting and a thermal magnetic circuit breaker (5.8) to protect the private devices from short circuits.

[0068] The AC input (5.3) from the grid or fuel generator, also with three conductors, is connected without additional protection via a male socket (5.9) integrated in the terminal box (1.4).

[0069] The DC connection of the battery module (2) is achieved by extending the two-core cable from the output of the inverter (1) and connecting it to the two-core cable from the battery terminal, using a single DC connector with two male and female parts at both ends. The connector (2.6) of the battery terminal and its protective magnetic thermal circuit breaker (2.5) are integrated in the side terminal box (2.4) of the battery module (2).

[0070] Figure 6a and Figure 6b A schematic diagram is shown that allows the integration of the power station into a private installation. To achieve this, the conductors (phase and neutral) of the outlet of the magnetothermal circuit breaker of the electrical installation panel (6.5) for the private installation's own consumption are cut together with the corresponding grounding connector. The ends are then extended in a single cable through an external conduit to the wall location of the inverter (1) and the terminal box (1.4).

[0071] Next, connect the female socket (6.2) to the live end coming out of the circuit breaker of the board and the end of the ground conductor connected to the electrode of the device. These will be connected to the AC input male socket (5.9). Another male socket (6.3) is connected to the non-live end of the circuit power supply along with the end of the circuit grounding conductor. These will be connected to the AC output female socket (5.6).

[0072] In this mode of operation, the power station can be operated with fixed solar panels located on roofs, exterior walls, gardens or terraces. Their two-core cables (6.1) also extend from the inside or outside to the location of the junction box (1.4). In the described arrangement, the inverter (1) will only use grid power when the energy generated by the solar panels and the energy stored in the battery modules (2) are not enough to power the circuit loads.

[0073] For example, in the portable mode shown in Figure 3A, the power station is compatible with portable solar panels as long as the same voltage specifications are met. In this case, the AC output socket (5.6) will be used to directly power the load of the required device, while the AC input socket (5.9) can be used to connect the output of the fuel generator to ensure power supply during interruptions.

[0074] The transition procedure between the two operating modes for energy storage and supply units and power stations is described below.

[0075] Figure 6a1 shows the appearance of the private device after the modification, when the user arrives at the fixed mode device with the portable power station. Figure 6a As shown, the cable end of the panel connection line (6.1) is loosened, and the male and female connectors (6.3 and 6.2) of the cut end of the selected self-consumption circuit outlet are coupled together (in the figure, they are slightly separated and their interconnection is shown by dotted lines). In this way, the circuit is powered only by the grid.

[0076] The first step is to disconnect the circuit breaker (5.4) of the panel connection line from the junction box (1.4). Then, disconnect the differential circuit breaker (5.7) of the AC output port (5.2) of the inverter (1). If there are multiple battery modules ( Figure 3c and Figure 3d ), disconnect the circuit breaker (2.5) and corresponding connector cable (3.4) of each side junction box (2.4) from the connector (2.6) of the battery terminal starting from the connector farthest from the connection of the inverter. Then, perform the same operation on the circuit breaker (2.5) of the side junction box (2.4) of the first battery module. This allows the connector (1.5) of the inverter to be safely unplugged from the connector (2.6) of the battery terminal in the side battery junction box (2.4).

[0077] The inverter and the battery modules are now separated and ready to be mounted on the wall. The user first decouples the inverter (1) from the first battery module (2) by pulling the handle (1.2) vertically and couples the inverter (1) to the wall by matching its rear fasteners (1.3) with complementary fasteners (4.3) on the wall. The user then decouples each battery module (2) from the cart (3) by pulling the handle (2.3) vertically and couples it to the wall by matching its rear fasteners (2.2) with complementary fasteners (4.4) on the wall. In this case, the next step is to reconnect the connector cable (4.7) to the connector (2.6) of the battery terminal of each adjacent side battery junction box (2.4) and reconnect the connector (1.5) of the inverter to the connector (2.6) of the battery terminal of the other side junction box (2.4).

[0078] Next, go to the circuit board (6.5), ensure that all devices in the circuit that are sensitive to power drops are turned off (usually electronic devices), disconnect the circuit's magnetic thermal circuit breaker, and then safely disconnect the male and female connectors (6.3 and 6.2) from the cut-off ends of the circuit output. Figure 6bThe three connections that the user then makes are shown: connecting the female socket (6.2) of the circuit breaker outlet to the male AC input connector (5.9) of the junction box (1.4); connecting the male socket (6.3) of the circuit to the female AC output connector (5.6); connecting the DC connector (6.1) of the panel connection line to the corresponding connector (5.5) integrated in the junction box (1.4).

[0079] Finally, the user reconnects the protective circuit breakers in the following order: first, the circuit breakers (2.5) of each side terminal box of the battery module are connected in the following order: starting from the farthest circuit breaker and ending with the circuit breaker connected to the inverter that initializes its electronics, then the circuit breakers of the battery panel connection lines (5.4), the magnetothermal circuit breakers of the circuit boards (6.5) and finally the differential circuit breaker of the AC output of the inverter (5.2).

[0080] The steps for switching from fixed mode to portable mode are the same as those described above, but in reverse order. The result is that the circuit is powered only by the mains (e.g. Figure 6a ), and the power station is configured in portable mode (as shown Figure 3a shown).
