Solar plug key set for photovoltaic connectors Key benefits Multifunctional design: multiple universal hole profiles and plugin mounting fittings allow secure clamping of a wide range of photovoltaic connectors and mating parts. Secure grip: positive clamping position resists loosening during tightening and loosening operations, reducing the risk of slipped connections. Time and effort saving: ergonomic shape and the ability to use two keys together enable faster tightening and quicker connector release, speeding up installation and maintenance. Lightweight and portable: compact, easy to carry tool that reduces fatigue during repetitive tasks and is convenient for field work. Main functions and compatibility Intended for tightening and loosening photovoltaic connector types commonly used in solar installations. Works as an assembly and disassembly key for inverter connector assemblies and for installing or removing photovoltaic fuses. Plugin mounting tools and universal hole designs provide broad compatibility without the need for multiple specialized wrenches. Practical attributes Function: tightening, loosening, assembly and disassembly of solar panel connector interfaces and fuses. Compatibility: fits most photovoltaic connector styles on the market through universal hole profiles and plugin mounting features. Ergonomics: shaped for comfortable hand use; twinkey operation speeds repetitive tasks. Portability: lightweight and compact for easy transport and onsite use. Typical use scenarios Rooftop system installation: quickly secure multiple string connector pairs during panel array assembly, using two keys together to accelerate work. Inverter maintenance and commissioning: access and tighten inverter DC connections and fuse assemblies during service calls. Field troubleshooting and panel replacement: carry the compact key for rapid disconnection and reconnection of PV connectors while minimizing downtime. This tool offers a practical, portable solution for PV installers and technicians who need a versatile wrench for common photovoltaic connector and fuse tasks.
