Abstract
Description
Technical Field

[0002] A photovoltaic optimizer is used to modulate the output of a photovoltaic module to ensure that the photovoltaic module operates at the maximum power point. It is one of the key devices in a photovoltaic power generation optimization system and has functions of energy collection and conversion, data sampling, and basic communication.
[0003] Existing optimizers usually include four wiring terminals, namely positive and negative input terminals and positive and negative output terminals. When in use, the optimizer is adhered to the backlight surface of the photovoltaic module, and the connection ends of the lead-out wires in the junction box of the photovoltaic module are respectively connected to the positive and negative input terminals. However, the four wiring terminals of the existing optimizer are respectively connected to the optimizer through wires, resulting in messy cables after connection, poor aesthetics, high cable cost of the optimizer, and possible entanglement between the cables, increasing the difficulty of later maintenance.
[0004] In addition, in order to electrically connect the lead-out wires of the existing junction box on the back of the photovoltaic module to adjacent photovoltaic modules, the lead-out wires are usually arranged at the position facing the outside of the junction box. Therefore, when an optimizer is added to the existing photovoltaic module, the lead-out wires need to be bent inward and then connected to the optimizer located between the two junction boxes. The connection operation is inconvenient, and the lead-out wire route is bent with a long travel, resulting in waste of lead-out wire materials. Summary of the Utility Model

[0030] In this embodiment, the optimizer body is an existing integrated circuit board containing an optimization circuit. The box body 100 is a hollow structure. The optimizer is arranged inside the box body 100, and the box body 100 protects the optimizer body to prevent the optimizer body from colliding with external objects or contacting external liquids, resulting in circuit damage, and improving the safety and service life of the optimizer body. The optimizer is integrated with an input end interface 200, and the input end interface 200 is connected to the box body 100, thereby ensuring the stability of the input end interface 200 and preventing the exposed input end from shaking or being pulled during use, resulting in the input port falling off. The input end interface 200 is connected to the circuit connector of the external photovoltaic module, so that the photovoltaic module is electrically connected to the optimizer main body. Existing photovoltaic modules usually reserve circuit connectors for connecting another photovoltaic module. Therefore, the circuit connector of the photovoltaic module can be directly used to connect to the input end interface 200 of the optimizer. The input end interface 200 is directly connected to the housing, which can ensure the stability of the interface while saving connection wires, avoiding damage caused by wire entanglement and pulling, saving costs, and improving aesthetics.

[0048] Please refer to Figure 2 As shown, the photovoltaic module uses the above photovoltaic module optimizer, which is convenient for wiring, the circuit connection is clear, convenient for inspection and maintenance, has a low cost, and there will be no winding and accumulation of wires, and has high aesthetics.
[0049] Optionally, in some implementation manners of this embodiment, a pair of junction boxes 600 are provided at the central position along the length direction on the back surface of the photovoltaic panel 500, and the junction boxes 600 are symmetric about the center line in the width direction of the photovoltaic panel 500. The photovoltaic module optimizer is disposed at the middle position between the pair of junction boxes 600.
[0050] Please refer to Figure 2 As shown, in this embodiment, the photovoltaic module optimizer is disposed on the back surface of the photovoltaic panel 500. Two junction boxes 600 are symmetrically disposed on the back surface of the photovoltaic panel 500, and the junction boxes 600 are respectively located on both sides of the photovoltaic module optimizer. The junction boxes 600 are connected to the input end interfaces 200 on both sides of the photovoltaic module optimizer through cables and connectors, avoiding the winding of the wires 400, increasing the orderliness of the wires 400, and facilitating later maintenance.

[0052] Please refer to Figure 2As shown, in this embodiment, two junction boxes 600 are provided with lead-out wires 700 on the side facing the photovoltaic module optimizer.
