Hopewind Electric Patents PV Terminal with Enhanced Waterproof and Dustproof Protection
Hopewind Electric (Shenzhen Hopewind Electric Co., Ltd.) has been granted a utility model patent for a photovoltaic (PV) terminal that significantly improves waterproof and dustproof performance for solar inverter applications .
Technical Design:
Features a housing and a conductive terminal
The housing contains a cavity with internal and external openings
The conductive terminal is positioned within the cavity
A first waterproof ring is clamped between the cylindrical section of the conductive terminal and the inner wall of the housing
Benefits:
The waterproof ring fills the gap between the terminal’s cylindrical section and the housing inner wall
Effectively prevents external moisture and contaminants from entering the PV inverter through the terminal
Significantly improves inverter reliability and safety
Prevents inverter damage in harsh outdoor PV installations
This innovation is particularly important for solar installations where equipment is exposed to rain, humidity, and dust. The terminal is designed for connecting the PV inverter’s circuit board to external cable connectors .
