It solves the problem that non-specialist personnel have difficulty adjusting photovoltaic panels to the optimal deployment angle in personal, decentralized photovoltaic panel deployment scenarios without dedicated tools, thereby improving the working efficiency and power generation of photovoltaic panels.
[0004] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.
[0005] According to a first aspect of the embodiments of this application, an optimizer supporting automated photovoltaic panel deployment angle optimization is provided, comprising: The power monitoring unit is connected to the output end of the photovoltaic panel and is used to monitor the real-time changes in the output power of the photovoltaic panel.

[0006] According to one embodiment of this application, the angle optimization prompting unit includes a buzzer. The buzzer provides feedback on the output power of the photovoltaic panel by emitting prompting sounds at different intervals. When the output power of the photovoltaic panel increases, the prompting sound interval decreases; when the output power of the photovoltaic panel decreases, the prompting sound interval increases. The optimizer records the output power of the photovoltaic panel during the adjustment process and obtains the maximum output power of the photovoltaic panel during the adjustment period. When the recorded output power of the photovoltaic panel reaches the maximum output power during the adjustment period or the maximum rated power supported by the optimizer, the buzzer emits continuous prompting sounds.
[0007] According to one embodiment of this application, the angle optimization prompting unit includes an indicator light, which provides feedback on the output power of the photovoltaic panel through different flashing intervals; when the output power of the photovoltaic panel increases, the flashing interval of the indicator light increases; when the output power of the photovoltaic panel decreases, the flashing interval of the indicator light decreases; the optimizer records the output power of the photovoltaic panel during the adjustment process and obtains the maximum output power of the photovoltaic panel during the adjustment period; when the recorded output power of the photovoltaic panel reaches the maximum output power during the adjustment period or the maximum rated output power supported by the optimizer, the indicator light remains constantly lit.
[0008] According to one embodiment of this application, the angle optimization opening unit is a physical button.
[0009] According to one embodiment of this application, the angle optimization activation unit controls the optimizer to enter the photovoltaic panel angle optimization mode by pressing a physical button externally for a preset time, pressing it repeatedly, or using a custom button mode.

[0011] According to one embodiment of this application, the angle optimization activation unit further includes: after entering the photovoltaic panel angle optimization mode, controlling the optimizer to exit the photovoltaic panel angle optimization mode by pressing the physical button again or after a preset time period.
[0012] According to a second aspect of the embodiments of this application, a photovoltaic panel angle optimization method based on the optimizer supporting automated photovoltaic panel deployment angle optimization described in the first aspect is provided, comprising: Connect the optimizer to the output of the photovoltaic panel; By optimizing the angle, the unit control optimizer enters the photovoltaic panel angle tuning mode. At this time, the power monitoring unit monitors the real-time changes in the output power of the photovoltaic panel. Adjusting the angle of the photovoltaic panel, the angle optimization prompt unit prompts the change in the output power of the photovoltaic panel through sound and / or light feedback information; The angle of the photovoltaic panel is continuously adjusted based on the sound and / or light feedback information from the angle optimization prompt unit until the optimal angle of the photovoltaic panel is reached, which is the angle at which the photovoltaic panel outputs the maximum power.
[0013] According to one embodiment of this application, when adjusting the angle of the photovoltaic panel, if the output power of the photovoltaic panel decreases, the interval of the buzzer's beeping sound is increased to prompt the user to adjust in the opposite direction; if the output power of the photovoltaic panel increases, the interval of the buzzer's beeping sound is decreased to prompt the user to continue adjusting in the current direction. At the same time, the output power of the photovoltaic panel during the adjustment process is recorded, and the maximum output power of the photovoltaic panel during the adjustment period is obtained. When the recorded output power of the photovoltaic panel reaches the maximum output power during the adjustment period or the maximum rated output power supported by the optimizer, the buzzer emits a continuous beeping sound.
[0014] According to one embodiment of this application, when adjusting the angle of the photovoltaic panel, if the output power of the photovoltaic panel decreases, the flashing interval of the indicator light is increased to prompt the user to adjust in the opposite direction; if the output power of the photovoltaic panel increases, the flashing interval of the indicator light is decreased to prompt the user to continue adjusting in the current direction; at the same time, the output power of the photovoltaic panel during the adjustment process is recorded, and the maximum output power of the photovoltaic panel during the adjustment period is obtained. When the recorded output power of the photovoltaic panel reaches the maximum output power during the adjustment period or the maximum rated output power supported by the optimizer, the indicator light remains on.
[0015] Compared with the prior art, the beneficial effects of adopting the above technical solution are as follows: The present invention creatively utilizes the optimizer connected to the photovoltaic panel to automatically measure the power generation of the photovoltaic panel at different deployment angles, and notifies the user through sound and light signals, so that non-dedicated users can optimize and adjust the deployment angle of the photovoltaic panel without dedicated equipment and software, thereby achieving the optimization of photovoltaic panel power generation.

[0024] In the description of this invention, the expression “A and / or B” (where A and B are used to formally represent specific features) will be used. The corresponding expression includes the following three combinations: only A, only B, and a combination of A and B.
[0025] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0026] Example 1 Please refer to Figure 1 , Figure 2 This embodiment proposes an optimizer 100 that supports automated photovoltaic panel deployment angle optimization. The optimizer 100 is directly connected to the output terminal of the photovoltaic panel 150 through a DC input line 140. The optimizer 100 includes a power monitoring unit, an angle optimization activation unit, and an angle optimization prompt unit.
[0027] It should be noted that the optimizer 100 in this embodiment is directly implemented on the basis of the existing photovoltaic optimizer. The existing photovoltaic optimizer mainly performs independent maximum power point tracking (MPPT) on the photovoltaic panel 150, optimizes its DC output voltage and current, and outputs them to the inverter.
[0028] In this embodiment, the power monitoring unit can be directly connected to the output terminal of the photovoltaic panel 150 to monitor the real-time changes in the output power of the photovoltaic panel 150. In one embodiment, the power monitoring unit can be implemented using the functional module of the optimizer 100 itself, or it can be implemented by adding a separate functional module.
[0029] The angle optimization activation unit is connected to the angle optimization prompt module. This unit is mainly used to control the optimizer 100 to enter the photovoltaic panel angle adjustment mode. The angle optimization prompt unit will only issue a corresponding prompt after entering the photovoltaic panel angle adjustment mode. When not entering this mode, the optimizer 100 can perform its own work.
[0030] The angle optimization prompt unit is connected to the power monitoring module. This unit is mainly used to prompt the user whether the photovoltaic panel 150 has reached the optimal angle after entering the photovoltaic panel angle optimization mode, based on the real-time changes in the output power of the photovoltaic panel 150.
[0031] With the cooperation of the angle optimization activation unit, the angle optimization prompt unit, and the power monitoring unit, users can control the optimizer 100 to enter the photovoltaic panel angle adjustment mode without using any professional equipment, and then adjust the photovoltaic panel 150 to the optimal angle according to the prompts of the angle optimization prompt unit.
[0032] Example 2 Based on Embodiment 1, this embodiment proposes an implementation method for an angle optimization prompting unit. In this embodiment, the angle optimization prompting unit is implemented using a buzzer 120. Specifically, after entering the photovoltaic panel angle optimization mode, the buzzer 120 emits prompts at different intervals to reflect the increase and decrease of output power based on the output power changes monitored by the power monitoring module. In this embodiment, when the output power of the photovoltaic panel 150 increases, the interval of the prompts emitted by the buzzer 120 decreases; when the output power of the photovoltaic panel 150 decreases, the interval of the prompts emitted by the buzzer 120 increases. In one embodiment, when the output power of the photovoltaic panel 150 reaches the maximum output power during the adjustment period or the maximum rated output power supported by the optimizer, the buzzer 120 emits continuous prompts. Specifically, the optimizer records the output power of the photovoltaic panel during the adjustment process and obtains the maximum output power of the photovoltaic panel during the adjustment period. When the recorded output power of the photovoltaic panel reaches the maximum output power during the adjustment period or the maximum rated power supported by the optimizer, the buzzer emits continuous prompts.
[0033] It should be noted that in other embodiments, other buzzer 120 prompt modes can be set as needed. For example, the interval between buzzer 120 prompt tones can increase with increasing power and decrease with decreasing power.
[0034] Furthermore, in this embodiment, the angle optimization unit can also indicate that the optimizer 100 has entered the photovoltaic panel angle optimization mode. For example, when the optimizer 100 is controlled to enter the photovoltaic panel angle optimization mode by the angle optimization activation unit, the buzzer 120 can emit a specific sound to indicate that the optimizer 100 has entered the photovoltaic panel angle optimization mode. This specific sound can be adjusted according to actual needs.
[0035] Example 3 Based on Embodiment 1, this embodiment proposes another implementation method for the angle optimization prompt unit. In this embodiment, the angle optimization prompt unit is implemented using an indicator light 130. Specifically, after entering the photovoltaic panel angle optimization mode, according to the output power changes monitored by the power monitoring module, the indicator light 130 uses different flashing intervals to reflect the increase and decrease of output power. In this embodiment, when the output power of the photovoltaic panel 150 increases, the flashing interval of the indicator light 130 increases; when the output power of the photovoltaic panel 150 decreases, the flashing interval of the indicator light 130 decreases. In one embodiment, when the output power of the photovoltaic panel 150 reaches the maximum output power during the adjustment period or the maximum rated output power supported by the optimizer, the indicator light 130 remains constantly lit. Specifically, the optimizer records the output power of the photovoltaic panel during the adjustment process and obtains the maximum output power of the photovoltaic panel during the adjustment period. When the recorded output power of the photovoltaic panel reaches the maximum output power during the adjustment period or the maximum rated output power supported by the optimizer, the indicator light remains constantly lit.
[0036] Similarly, in other embodiments, the indicator light 130 can be configured to use other flashing modes as needed. For example, the flashing interval of the indicator light 130 can increase with increasing power and decrease with decreasing power.
[0037] Furthermore, in this embodiment, the angle optimization unit can also indicate to the optimizer 100 that it has entered the photovoltaic panel angle optimization mode. For example, when the optimizer 100 is controlled to enter the photovoltaic panel angle optimization mode by the angle optimization activation unit, the indicator light 130 can use a specific flashing pattern to indicate that the optimizer 100 has entered the photovoltaic panel angle optimization mode. This specific flashing pattern can be adjusted according to actual needs.
[0038] Example 4 Based on Embodiment 1, this embodiment proposes another implementation method for the angle optimization prompt unit. In this embodiment, the angle optimization prompt unit is implemented using both an indicator light 130 and a buzzer 120. That is, after entering the photovoltaic panel angle optimization mode, based on the output power changes monitored by the power monitoring module, the buzzer 120 and indicator light 130 simultaneously provide feedback on the increase or decrease of output power. Specifically, when the output power of the photovoltaic panel 150 increases, the flashing interval of the indicator light 130 increases, and the interval of the prompt tone emitted by the buzzer 120 decreases; when the output power of the photovoltaic panel 150 decreases, the flashing interval of the indicator light 130 decreases, and the interval of the prompt tone emitted by the buzzer 120 increases. When the output power of the photovoltaic panel 150 reaches the maximum output power during the adjustment period or the maximum rated output power supported by the optimizer, the indicator light 130 remains constantly lit, and the buzzer 120 emits a continuous prompt tone.
[0039] Example 5 Based on any of the embodiments 1 to 4, in this embodiment, the angle optimization activation unit uses a physical button 110 as the human-machine interaction button. In practical applications, different button modes can be selected to control the optimizer 100 to enter the photovoltaic panel angle optimization mode according to requirements. For example, the photovoltaic panel angle optimization mode can be entered by pressing the physical button 110 for a preset time or by pressing it repeatedly, avoiding accidental entry into the photovoltaic panel angle optimization mode due to accidental touch.
[0040] In some embodiments, other custom button modes can also be configured.
[0041] Furthermore, the angle optimization activation unit also provides the function of controlling the optimizer 100 to exit the photovoltaic angle optimization mode. Specifically, after the optimizer 100 enters the photovoltaic angle optimization mode, the photovoltaic panel angle optimization mode can be exited by pressing the physical button 110 again. In some embodiments, after the optimizer 100 enters the photovoltaic angle optimization mode, the optimizer 100 exits the photovoltaic panel angle optimization mode after a preset time period (e.g., 5 minutes).
[0042] The optimizers provided in Examples 1 to 5 automatically measure the power generation of photovoltaic panels at different deployment angles and notify users through sound and light signals, so that non-dedicated users can optimize the deployment angle of photovoltaic panels without dedicated equipment or software, thereby achieving the optimal power generation of photovoltaic panels.
[0043] Example 6 Based on the foregoing embodiments, this embodiment proposes a method for optimizing the angle of a photovoltaic panel. Please refer to [link / reference]. Figure 3 Specifically, it includes the following steps: S201. Connect the optimizer to the output terminal of the photovoltaic panel.
[0044] In practical applications, the optimizer is connected to the output of the photovoltaic panel. After entering the photovoltaic panel angle optimization mode, it can control the angle optimization prompt unit to assist the user in adjusting the photovoltaic panel angle. When not in the photovoltaic panel angle optimization mode, it can perform independent maximum power point tracking (MPPT) on the photovoltaic panel to optimize its DC output voltage and current and output them to the inverter.
[0045] S202. The angle optimization unit control optimizer enters the photovoltaic panel angle adjustment mode. At this time, the power monitoring unit monitors the real-time changes in the output power of the photovoltaic panel.
[0046] After the optimizer is connected to the photovoltaic (PV) panel, the initial output power of the PV panel can be directly obtained. Generally, angle adjustment is required during PV panel deployment. Users can enter the PV panel angle adjustment mode by pressing the preset button mode on the angle optimization activation unit. Once the angle optimization prompt unit indicates entry into PV panel angle adjustment mode, the PV panel angle adjustment can begin. It should be noted that during the adjustment process, the power monitoring unit will acquire the PV panel's output power in real time and compare the output power changes before and after angle adjustment.
[0047] S203. Adjust the angle of the photovoltaic panel. The angle optimization prompt unit prompts the photovoltaic panel output power change through sound and / or light feedback information.
[0048] During the process of adjusting the angle of the photovoltaic panel, the angle optimization prompt unit can indicate whether the output power of the photovoltaic panel is increasing or decreasing through different sound and / or light feedback information. At this time, the user can adjust the angle orientation according to the corresponding sound and / or light feedback information.
[0049] S204. The angle of the photovoltaic panel is continuously adjusted based on the sound and / or light feedback information from the angle optimization prompt unit until the optimal angle of the photovoltaic panel is reached, that is, the angle at which the photovoltaic panel outputs the maximum power.
[0050] In this embodiment, the user repeatedly adjusts the left-right and tilt angles of the photovoltaic panel, and then determines which angle generates the most power based on the beep interval of the optimizer or the flashing interval of the indicator light. Finally, the angle at which the photovoltaic panel generates the most power is fixed, thus completing the optimization of the photovoltaic panel deployment angle.
[0051] In practical applications, if a user uses a buzzer to determine the direction of angle adjustment when adjusting the photovoltaic panel, if the photovoltaic panel's output power decreases, the interval between the buzzer's beeps will increase, indicating that the user needs to adjust in the opposite direction; if the photovoltaic panel's output power increases, the interval between the buzzer's beeps will decrease, indicating that the user should continue adjusting in the current direction. Simultaneously, the output power of the photovoltaic panel during the adjustment process is recorded, and the maximum output power of the photovoltaic panel during the adjustment period is obtained. When the recorded output power of the photovoltaic panel reaches the maximum output power during the adjustment period or the maximum rated output power supported by the optimizer, the buzzer emits a continuous beep.
[0052] Furthermore, if the user uses indicator lights to determine the direction of angle adjustment when adjusting the photovoltaic panel angle, if the photovoltaic panel's output power decreases, the flashing interval of the indicator light will increase, indicating that the user needs to adjust in the opposite direction; if the photovoltaic panel's output power increases, the flashing interval of the indicator light will decrease, indicating that the user should continue adjusting in the current direction. Simultaneously, the output power of the photovoltaic panel during the adjustment process is recorded, and the maximum output power of the photovoltaic panel during the adjustment period is obtained. When the recorded output power of the photovoltaic panel reaches the maximum output power during the adjustment period or the maximum rated output power supported by the optimizer, the indicator light remains constantly on.
[0053] The optimizer and optimization method proposed in the above embodiments can effectively solve the problem of adjusting photovoltaic panels to the optimal deployment angle without specialized tools in personal, decentralized photovoltaic panel scenarios, thereby improving the working efficiency and power generation of photovoltaic panels.
