These terms are primarily used to distinguish one component from another, or one signal from another. Furthermore, the term "or" as used herein should, as appropriate, include any combination of one or more of the related listed items.

[0025] [Example]

[0026] Please see Figures 1 to 7 This utility model provides a solar inverter with a power transmission end replacement component. For example... Figure 1 , Figure 2 As shown, the solar inverter with a power transmission end replacement component provided by this utility model (hereinafter referred to as the solar inverter) basically includes a body 10 and a power transmission end replacement component A1. The solar inverter may also include a cover 20 that can be detached from the body 10.

[0027] The machine body 10 has internal circuits, such as inverter circuits, boost circuits, and protection circuits, which can provide the circuits for the normal operation of the entire machine.

[0028] The cover 20 is screwed onto the body 10 and covers the internal circuitry of the body 10, so as to close or expose the internal circuitry of the body 10. In other embodiments, the cover 20 is attached to the body 10 in other ways.

[0029] The power transmission end replacement component A1 is located on the side end of the body 10, which may be the bottom side end of the body 10. The power transmission end replacement component A1 may include a replaceable first power transmission end replacement module 30 and a second power transmission end replacement module 40. The power transmission end replacement component A1 may also be either the replaceable first power transmission end replacement module 30 or the second power transmission end replacement module 40.

[0030] Furthermore, the first power transmission end replacement module 30 can be alternatively disposed on the side of the body 10. The first power transmission end replacement module 30 can be a DC power output / input replacement module of a solar inverter.

[0031] Therefore, when Figure 2 When the power transmission end replacement component A1 is the first power transmission end replacement module 30, the first power transmission end replacement module 30 is as follows: Figure 3 As shown, at least one unit with a quick-connect cable 900 is located on the side of the housing 10, allowing it to be connected to the first power transmission terminal replacement module 30. This module then electrically connects to the internal circuitry of the housing 10, enabling DC power transmission to the internal circuitry and facilitating DC power input. Additionally, the solar inverter can also output energy through at least one unit with a quick-connect cable 900 to charge the battery module.

[0032] Furthermore, the second power transmission terminal replacement module 40 can be alternatively located on the side of the unit 10. The second power transmission terminal replacement module 40 can be another DC power output / input terminal replacement module for the solar inverter.

[0033] Therefore, when Figure 2 When the power transmission end replacement component A1 is the second power transmission end replacement module 40, the second power transmission end replacement module 40 is as follows: Figure 4 As shown, at least one locked-wire cable 800 is provided on the side of the housing 10 so that it can be threaded through the second power transmission terminal replacement module 40 and electrically connected to the internal circuit of the housing 10 through the extension segment 801 of the locked-wire cable 800, thereby transmitting DC power to the internal circuit of the housing 10 and realizing DC power input. In addition, the solar inverter can also output energy through the locked-wire cable 800 to charge the battery module.

[0034] As described above, by using the power transmission end replacement component A1 as a replaceable first power transmission end replacement module 30 or second power transmission end replacement module 40, it is possible to be compatible with different types of cable connections, increasing the flexibility of installation and use.

[0035] Furthermore, in this embodiment, the side end, that is, the bottom end, of the body 10 has an opening 110 (e.g., Figure 5 , Figure 6 (As shown). Furthermore, a reserved space 11 is formed inside the body 10, or rather, the aforementioned opening 110 is formed at the bottom end of the reserved space 11 of the body 10.

[0036] In one embodiment, the first power transmission end replacement module 30 is as follows: Figure 6 The diagram shows a first interconnecting plate 33 with an opening 110 corresponding to its position or size, a plurality of connectors 31 disposed on the first interconnecting plate 33, and a plurality of conductive metal extensions 32 respectively connected to the plurality of connectors 31. The conductive metal extensions 32 are used for electrical connection to the internal circuitry of the body 10. Further, the connectors 31 of the first power transmission terminal replacement module 30 pass through the first interconnecting plate 33, and the first interconnecting plate 33 is detachably disposed at the opening 110. This allows the first input terminal replacement module 30 to be alternatively disposed on the side of the reserved space portion 11 via the first interconnecting plate 33, so that at least one cable with a quick-connect cable 900 can be connected to at least one pair of connectors 31 of the first power transmission terminal replacement module 30, and can be electrically connected to the internal circuitry of the body 10 via at least one conductive metal extension 32.

[0037] In one embodiment, the second power transmission terminal replacement module 40 is as follows: Figure 5The diagram shows a second interconnecting plate 42 with an opening 110 corresponding to its position or size, and a plurality of connectors 41 disposed on the second interconnecting plate 42, with each connector 41 having a wiring through-hole 411. Further, the connectors 41 of the second power transmission end replacement module 40 pass through the second interconnecting plate 42, and the second interconnecting plate 42 is detachably disposed at the opening 110, allowing the second power transmission end replacement module 40 to be alternatively disposed on the side end of the reserved space portion 11 of the body 10 via the second interconnecting plate 42. This allows at least one locked-wire cable 800 to pass through at least one wiring through-hole 411 of the second power transmission end replacement module 40, and to be electrically connected to the internal circuitry of the body 10 via the extension segment 801 of the at least one locked-wire cable 800 located in the reserved space portion 11. Furthermore, the wire-locked cable 800 (a bare wire with a locked connection) can pass through the connection port 411 of the connector 41 to the second interconnecting plate 42, and the inner wall of the connection port 411 can clamp the cable (bare wire), thereby eliminating the gap between the cable (bare wire) and the connection port 411 and achieving a sealing effect. In detail, the cable (bare wire) can be tightened by screwing a screw ring 412 that is screwed into the connector 41 to press the inner wall of the connection port 411.

[0038] In one embodiment, the dimensions of the first interconnect plate 33 and the second interconnect plate 42 are not smaller than the dimensions of the opening 110, so that the first interconnect plate 33 and the second interconnect plate 42 can selectively cover and close the opening 110. Furthermore, the first interconnect plate 33 and the second interconnect plate 42 are of the same size, so that the first interconnect plate 33 and the second interconnect plate 42 can share the locking holes formed around the opening 110 of the body 10 to cover and close the opening 110 by screw locking, but this is not a limitation.

[0039] In one embodiment, the first power transmission terminal replacement module 30 has a plurality of connectors 31 and a plurality of conductive metal extensions 32. For example... Figure 3 , Figure 6 As shown, the first power transmission terminal replacement module 30 has four connectors 31 and two conductive metal extensions 32. Each connector 31 has a mating end 311 and an opposite connecting end 312 located on both sides of the first interconnect plate 33. Each conductive metal extension 32 can be made of highly conductive copper. Each conductive metal extension 32 has a horizontal connecting section 321 and a connected vertical extension section 322. The horizontal connecting section 321 can be parallel to the bottom end of the body 10, and the vertical extension section 322 can be perpendicular to the bottom end of the body 10. Furthermore, the horizontal connecting section 321 of each conductive metal extension 32 is connected to the connecting ends 312 of the corresponding two connectors 31.

[0040] Furthermore, the internal circuitry of the housing 10 may include or contain a protection circuit 101. The housing 10 has a conductor 12 electrically connected to the protection circuit 101, and the vertical extension 322 of the conductive metal extension 32 is configured to connect to the conductor 12. In this embodiment, the protection circuit 101 is located at the upper end of the reserved space 11 and electrically connected to the conductor 12. The protection circuit 101 may be a circuit breaker, used to protect the internal circuitry of the housing 10 from overcurrent damage and prevent fire risks, thereby increasing safety.

[0041] In one embodiment, such as Figure 3 , Figure 6 As shown, the four connectors 31 can be divided into two positive connectors 31a and two negative connectors 31b, and the two conductive metal extensions 32 can be divided into one positive conductive metal extension 32a and one negative conductive metal extension 32b. The horizontal connecting section 321 of the positive conductive metal extension 32a is connected to the connecting end 312 of the two positive connectors 31a, and the horizontal connecting section 321 of the negative conductive metal extension 32b is connected to the connecting end 312 of the two negative connectors 31b.

[0042] In one embodiment, such as Figure 4 As shown, the connector 12 is electrically connected to the internal circuitry of the body 10 (such as the protection circuit 101, etc.), and the connector 12 can guide the input DC power supply to the internal circuitry of the body 10. The connector 12 can be composed of any number of connector plates and / or connector posts, but is not limited thereto. The connector 12 is fixed inside the reserved space 11 of the body 10 and is located at the upper end of the reserved space 11 of the body 10, so that the wire-locking cable 800 (bare wire) must extend upwards to the upper end of the reserved space 11 of the body 10 for connection, in order to meet safety requirements.

[0043] In one embodiment, such as Figure 3 As shown, the conductive member 12 has a positive electrode contact portion 121 and a negative electrode contact portion 122. The vertical extension section 322 of the positive electrode conductive metal extension 32a is configured to be connected to the positive electrode contact portion 121, and the vertical extension section 322 of the negative electrode conductive metal extension 32b is configured to be connected to the negative electrode contact portion 122.

[0044] In one embodiment, Figure 2 The power transmission terminal replacement component A1 may further include Figure 7The system includes a third power transmission terminal replacement module 50 and a fourth power transmission terminal replacement module 60. The third power transmission terminal replacement module 50 and the fourth power transmission terminal replacement module 60 are spaced apart and interchangeably located on the side of the unit 10. The third power transmission terminal replacement module 50 can be an AC power output / input replacement module for the solar inverter. The fourth power transmission terminal replacement module 60 can be a DC power input replacement module for the solar inverter.

[0045] In summary, the solar inverter provided by this utility model, by replacing the power transmission end replacement component A1 with either the first power transmission end replacement module 30 or the second power transmission end replacement module 40, can be adapted to the connection requirements of quick-connect cables and lock-lock fixed cables, thereby improving the convenience and applicability of installation.
