Description

Technical Field

[0001] This invention belongs to the field of photovoltaic power equipment technology, specifically relating to a highly environmentally adaptable magnetic photovoltaic inverter. Background Technology

[0002] As the core equipment of a photovoltaic power generation system, the photovoltaic inverter plays a crucial role in converting the direct current (DC) generated by photovoltaic modules into alternating current (AC). Its performance directly determines power generation efficiency and operational safety. However, existing photovoltaic inverters face numerous environmental adaptability and structural design issues in practical applications: Firstly, traditional inverter casings are mostly conventional square structures with a single heat dissipation surface layout, making it easy for internal heat to accumulate. Especially in high-altitude, humid, and high-temperature outdoor environments, low heat dissipation efficiency directly leads to reduced equipment operating efficiency, accelerated component aging, power imbalance, and severely impacts service life. Secondly, existing inverters mostly use traditional wired structures for power output, which are cumbersome to connect. In outdoor construction and temporary power supply scenarios, the ease of disassembly and connection is poor, and the wiring points are susceptible to dust and moisture corrosion, causing poor contact. Therefore, improvements are necessary to address these issues. Summary of the Invention

[0003] The technical problem solved by this invention is to provide a highly environmentally adaptable magnetic photovoltaic inverter. It adopts a hollow isosceles trapezoidal shell with heat dissipation grilles on the front, left, right, and bottom walls, forming a dual heat dissipation structure in conjunction with the heat sink inside the shell. This solves the problems of component aging and power imbalance caused by low heat dissipation efficiency in traditional inverters, extending the equipment's service life. The magnetic connection and power output structure effectively replaces the traditional wiring structure, eliminating the need for cumbersome wiring operations. It enables rapid power connection in outdoor construction and temporary power supply scenarios, improving the stability of power transmission and operational safety and convenience. It is particularly suitable for use in high-altitude, humid, and high-temperature outdoor environments.

[0004] The technical solution adopted in this invention is a highly environmentally adaptable magnetic photovoltaic inverter, comprising a hollow isosceles trapezoidal shell with a heat dissipation grille. Inside the shell are magnetic rings, a detection and protection display unit, a heat sink, a battery, and an energy processing unit. The battery is connected to the energy processing unit and the heat sink via a DC power supply box and the detection and protection display unit, providing them with the necessary power. An information acquisition port on the top of the shell is connected to the input of the energy processing unit, and the photovoltaic module is connected to the information acquisition port via a line. The energy processing unit converts the light energy collected by the photovoltaic module into electrical energy. Multiple magnetic rings are connected in parallel to the output of the energy processing unit, and the energy is output through the magnetic rings.

[0005] The power processing unit includes a photovoltaic power converter, a capacitor plate, and an inductor. The capacitor plate has the same shape as the housing and is fixed to the inner rear wall of the housing. The capacitor plate has a clearance hole for the photovoltaic power converter, inductor, detection and protection display unit, heat sink, DC power box, magnetic rings, and battery to pass through and be fixedly connected to the inner rear wall of the housing. The input end of the photovoltaic power converter is connected to the information acquisition port, and the output end of the photovoltaic power converter is connected to the input end of the capacitor plate. The output end of the capacitor plate is connected to the input end of the inductor, and multiple magnetic rings are connected in parallel to the output end of the inductor.

[0006] Furthermore, there are three magnetic attraction rings, one of which is fixed to the rear side wall of the housing through the corresponding clearance hole on the capacitor plate, and the other two magnetic attraction rings are fixed to the left and right side walls of the housing respectively. The magnetic attraction ends of the three magnetic attraction rings are all located on the outer wall of the housing.

[0007] Furthermore, the detection and protection display unit includes a leakage current protector and a current display screen. The heat dissipation grille on the front side of the housing has an installation port, and the panel of the current display screen, which is fixed inside the housing, is adapted to be fixed at the installation port. The battery is connected to the input terminal of the DC power box, and the output terminal of the DC power box is connected in series with the current display screen through the leakage current protector. The photovoltaic power generation converter, capacitor plate, and heat sink are connected in parallel to the output terminal of the current display screen.

[0008] Furthermore, the panel of the current display screen includes a display surface and a display switch.

[0009] Furthermore, the on / off control switches for the DC power box and the photovoltaic power converter are both located on the side wall of the housing.

[0010] Furthermore, the outer surface of the heat dissipation grille is coated with an anti-salt spray nano-coating.

[0011] Furthermore, a positioning groove is formed on the rear wall of the housing, and the housing is detachably fixed to the solar photovoltaic panel by a top bolt with its large end located in the positioning groove.

[0012] Furthermore, heat dissipation grilles are formed on the front wall, left and right side walls, and bottom wall of the housing.

[0013] Advantages of this invention compared to existing technologies: 1. The housing of this technical solution adopts a hollow isosceles trapezoidal structure, and heat dissipation grilles are set on the front wall, left and right side walls and bottom wall. The multi-faceted heat dissipation layout greatly increases the heat dissipation area. Combined with the structural design of the housing, it realizes efficient internal air circulation and effectively avoids heat accumulation. At the same time, the heat sink set in the housing forms a dual heat dissipation structure with the heat dissipation grilles, which solves the problems of component aging and power imbalance caused by the low heat dissipation efficiency of traditional inverters, and extends the service life of the equipment. 2. This technical solution innovates the connection method and reduces transmission loss. It adopts three multi-directional magnetic rings to realize magnetic connection and power output, replacing the traditional wiring structure. This effectively reduces contact resistance and line loss, and eliminates the need for cumbersome wiring operations. It can achieve rapid power connection in outdoor construction, temporary power supply and other scenarios. Moreover, with the installation position sealed, the magnetic end is located on the outer wall of the shell, which effectively reduces the corrosion of the power transmission parts by dust and moisture, avoids poor contact, and improves the efficiency, stability and ease of operation of power transmission. 3. The heat dissipation grille of this technical solution is coated with an anti-salt spray nano-coating, which can effectively resist the corrosion of salt spray and water vapor, and is suitable for special outdoor environments such as coastal areas and high humidity. The isosceles trapezoidal shell structure design also improves the structural stability of the equipment under severe weather conditions such as strong winds and rainstorms, and greatly expands the applicable scenarios of the equipment. 4. This technical solution is equipped with a detection and protection display unit consisting of a leakage current protector and a current display screen. The leakage current protector can protect the circuit from leakage and can immediately disconnect the circuit when leakage abnormality occurs to avoid electrical safety accidents. The current display screen can display the circuit current parameters in real time. Operators can keep track of the equipment's operating status through the displayed data. The display screen is also equipped with a switch to control the on / off state as needed. 5. The rear wall of the housing of this technical solution is equipped with a positioning groove, which is detachably fixed to the solar photovoltaic panel by the top bolts. The positioning groove realizes the precise positioning of the bolts, making the connection between the equipment and the photovoltaic panel more stable, while greatly simplifying the disassembly and assembly steps, and facilitating the daily maintenance, replacement and relocation of the equipment. 6. This technical solution optimizes energy conversion and improves system efficiency. Through integrated magnetic attraction design, it simplifies the circuit path and reduces energy loss in intermediate links, significantly improving the overall electrical conversion rate compared to traditional inverters.

[0018] A highly environmentally adaptable magnetic photovoltaic inverter includes a hollow isosceles trapezoidal housing 8. The housing 8 has heat dissipation grilles 1, specifically on the front wall, left and right side walls, and bottom wall. This creates a three-dimensional ventilation channel between the interior and exterior of the housing 8. The perforated structure of the heat dissipation grilles 1 ensures sufficient heat dissipation area while preventing the intrusion of large particles. The outer surface of the heat dissipation grilles 1 is coated with an anti-salt spray nano-coating, balancing heat dissipation efficiency and corrosion resistance. This effectively prevents corrosion from salt spray and moisture, making it suitable for special environments such as coastal areas and high humidity. A positioning groove 16 is formed on the rear wall of the housing 8, and the housing 8 is detachably fixed to the solar photovoltaic panel via a top bolt 15 with its large end located within the positioning groove 16. Inside the housing 8 are a magnetic attraction ring 6, a detection and protection display unit, a heat sink 10, a battery 9, and a power processing unit. The battery 9 is connected to the power processing unit and the heat sink 10 via a DC power box 13 and the detection and protection display unit. The battery 9 is connected to the power processing unit and the heat sink 10 via the DC power box 13 and the detection and protection display unit, achieving precise control and protection of power supply. The information acquisition port 4 on the top of the housing 8 is connected to the input end of the power processing unit, and the photovoltaic module is connected to the information acquisition port 4 via a line. The power processing unit converts the light energy collected by the photovoltaic module into electrical energy. The output end of the power processing unit is connected in parallel with multiple magnetic rings 6, and the power of the power processing unit is output through the magnetic rings 6. The magnetic rings 6 have the dual functions of magnetic connection and conduction. Adjacent inverters are precisely aligned through the magnetic rings 6 to achieve wireless transmission of 220V AC power, replacing the traditional cable connection and avoiding transmission failures caused by cable aging and interface corrosion. The string design supports horizontal and vertical splicing of multiple inverters, making expansion convenient. The cooperation between the heat sink 10 and the heat dissipation grille 1 avoids efficiency degradation caused by a sudden increase in the internal temperature of the inverter, ensuring stable operation.

[0019] The power processing unit is specifically as follows: The power processing unit includes a photovoltaic power converter 7, a capacitor plate 5, and an inductor 11. The capacitor plate 5 has the same shape as the housing 8 and is fixed to the inner rear wall of the housing 8. The capacitor plate 5 has pre-drilled clearance holes 14 for the photovoltaic power converter 7, inductor 11, detection and protection display unit, heat sink 10, DC power box 13, magnetic ring 6, and battery 9 to pass through and be fixedly connected to the inner rear wall of the housing 8, allowing internal components to quickly pass through and be fixed to the rear wall of the housing 8, improving the assembly and maintenance efficiency of the equipment. The input end of the photovoltaic power converter 7 is connected to the information acquisition port 4, and the output end of the photovoltaic power converter 7 is connected to the input end of the capacitor plate 5. The output end of the capacitor plate 5 is connected to... The input terminal of inductor 11 is connected, and multiple magnetic rings 6 are connected in parallel to the output terminal of inductor 11. Capacitor plate 5 filters and regulates the power, and its output terminal is connected to the input terminal of inductor 11. Inductor 11 further filters and regulates the power to make the power output more stable. Multiple magnetic rings 6 are connected in parallel to the output terminal of inductor 11 to realize the magnetic output of power. Among them, there are three magnetic rings 6, and one magnetic ring 6 passes through the corresponding clearance hole 14 on the capacitor plate 5 and is fixed to the rear side wall of the housing 8. The other two magnetic rings 6 are fixed to the left and right side walls of the housing 8 respectively. The magnetic ends of the three magnetic rings 6 are all located on the outer wall of the housing 8. The multi-directional arrangement makes the power connection more flexible and adaptable to different power use scenarios.

[0020] The detection and protection display unit is as follows: The detection and protection display unit includes a leakage current protector 12 and a current display screen 2. A mounting port is provided on the heat dissipation grille 1 on the front side of the housing 8, and the panel of the current display screen 2, fixed inside the housing 8, is adapted and fixed at the mounting port. The battery 9 is connected to the input terminal of the DC power supply box 13, and the output terminal of the DC power supply box 13 is connected in series with the current display screen 2 through the leakage current protector 12. The photovoltaic power generation converter 7, capacitor plate 5, and heat sink 10 are connected in parallel to the output terminal of the current display screen 2. The current display screen 2 is an integrated component, housing a photovoltaic control board MCU, which is connected via electricity... The capacitor 5 supplies power to the photovoltaic control board MCU in series from the positive terminal of the DC power box 13, and the negative terminal of the DC power box 13 is connected to the photovoltaic power converter 7 to close the loop, so that the power supply circuit of the photovoltaic control board MCU is fully connected, ensuring reliable current sampling and control signal transmission. Specifically, the panel of the current display screen 2 includes a display surface and a display switch 3. The display switch 3 is used to control the on / off state of the current display screen 2. The current display screen 2 displays the current parameters in the circuit in real time, which makes it easy for operators to grasp the operating status of the equipment. The on / off control switches 17 of the DC power box 13 and the photovoltaic power converter 7 are both located on the side wall of the housing 8.

[0021] When using this invention, the housing 8 is first fixed to the solar photovoltaic panel by the top bolts 15. During operation, the magnetic ring 6 is checked to ensure that it is firmly attracted. Then, the photovoltaic module's wiring is connected to the information acquisition port 4 on the top of the housing 8 to ensure that the wiring is firm and the positive and negative poles are correct, so as to avoid damage to the equipment due to reverse connection. The magnetic ring 6 fits snugly with the wiring interface to enhance the stability of current transmission. After opening the DC power box 13 and confirming that there are no abnormalities in the internal wiring, slowly turn the on / off control switch 17 of the DC power box 13 to the closed position. At this time, the circuit inside the DC power box 13 is connected. Press the display switch 3 to start the current display screen 2. The battery 9 starts to supply power to the equipment. The heat sink 10 works in conjunction with the multi-faceted heat dissipation grilles 1 of the casing 8 to achieve dual heat dissipation of the equipment and avoid internal heat accumulation. The leakage protector 12 provides leakage protection for the entire circuit. The capacitor plate 5 enters the energy storage preparation state. The inductor 11 starts synchronously and begins to filter current impurities. Confirm that the display panel of the current display screen 2 is displaying normally without garbled characters or a black screen. At this time, the current display screen 2 will gradually display the voltage of the battery 9, which can be monitored in real time by the operator.

[0022] Turn on the on / off control switch 17 of the photovoltaic power generation converter 7 and observe the photovoltaic power generation converter 7 to confirm that it starts normally without abnormal noise or odor. At the same time, check the operating status of the capacitor plate 5 and the inductor 11. There should be no abnormalities such as overheating or abnormal noise. The capacitor plate 5 begins to store energy stably, and the inductor 11 continuously filters the current to ensure the energy conversion efficiency. After the equipment has been running for 3-5 minutes, and the data displayed on the current display 2 has stabilized, check the status of the leakage current protector 12 to confirm that it is still in normal standby mode and there is no tripping. Check the heat dissipation grille 1 and the radiator 10 to confirm that the heat dissipation system has started working without blockage or abnormal noise. Confirm that all components are operating normally and the data on the current display 2 is stable. The inverter has officially entered the working state and has begun to convert photovoltaic power into usable power, completing the conversion process.

[0023] The inverter of this invention can adopt a parallel circuit design when operating in a string configuration. This design ensures that the tripping or failure of a single inverter does not affect the normal power transmission of other equipment, thus guaranteeing the overall power supply stability of the system.
