Description

Technical Field

[0001] The utility model relates to the field of inverter devices, in particular to a micro string inverter. Background Art

[0002] Some existing micro-inverters can enable each panel to output independently. This module can keep other panels working normally and maintain high efficiency when some panels are blocked or polluted. String inverters connect multiple panels in series and then optimize them. When affected by a single panel, the efficiency of the entire series group may decrease.

[0003] In the prior art, some string inverter devices are usually more economical than other types of inverters because they generally only need one inverter to process the output of multiple solar panels in series, so this one-to-many processing reduces the cost per watt. However, some existing micro string inverters are fixed during installation, which makes it very inconvenient to disassemble the inverter. The fixed part needs to be removed before the inverter can be removed. Utility Model Content

[0026] like Figure 1-Figure 3 As shown: the cabinet 1 is internally fixedly connected with a wiring module 13, which is modular and easy to replace. The wiring module 13 is externally fixedly connected with a linear current connector 14. In order to access the direct current generated by solar energy, the wiring module 13 is externally fixedly connected with an isolation block 15. In order to isolate other devices, the linear current connector 14 is externally fixedly connected with a plug 32. The wiring module 13 is externally fixedly connected with a current port 16.
