Patent ID: 10250186

Abstract:
A detachable split solar power optimization junction box module has split junction boxes (1A, 1B, 1C) each having a base part and an upper cover part. String ports (11) are provided in a base (10) of the base part for electrically connecting a string of a photovoltaic module (40). The upper cover part has an upper cover (20) with a circuit board (21) provided therein. The circuit board (21) has a power optimization module connected with electrical connection pieces (22). The electrical connection pieces (22) are detachably inserted into the string ports (11) so that the power optimization module performs power optimization on the string of the photovoltaic module. The split junction boxes (1A, 1B, 1C) are used for power optimization at the string level. The power optimization module is integrated in the upper cover part that detachably connects with the base part for convenience of installation and maintenance.
