Customer feedback worldwide
We ordered these IP68-rated connectors for a commercial outdoor-lighting project. After several periods of heavy rain, the installed connections have remained reliable. The housings feel solid and the threads engage smoothly.
We replaced connectors from a lower-cost supplier with PVLinkTech’s MC4-compatible connectors. The locking action feels secure, and installation has been straightforward. We plan to consider them again for an upcoming solar project.
Sehr solide verarbeitet. Wir verwenden die IP68-klassifizierten Steckverbinder regelmäßig in Außenanlagen. Die Dichtungen machen einen robusten Eindruck, und die Montage geht schnell von der Hand.
The junction boxes feel robust, and the gaskets seated well during installation. The shipping carton arrived slightly damaged, but the components inside were unaffected.
We use these energy-storage connectors in commercial battery installations in a cold climate. Installation was straightforward, and the connectors have performed reliably under our normal operating conditions.
The MC4-compatible solar connectors fit securely and have worked as expected. Delivery to California took nearly three weeks, so faster shipping would improve the overall experience.
Ces boîtes de dérivation sont de bonne qualité. Nous les utilisons pour un système d’irrigation agricole et, après plusieurs mois d’exposition aux intempéries, l’installation fonctionne toujours comme prévu.
We have used these energy-storage connectors on battery systems under normal operating loads, and they have performed reliably. PVLinkTech also supplied the requested specification drawings promptly.
These circular signal connectors have worked well in our factory-automation project. They cost slightly more than some local alternatives, but the construction and fit have met our requirements.
Degelijke waterdichte lasdozen. Ze zijn eenvoudig te installeren en de wartels sluiten de kabels goed af. Voor onze tuinverlichting voelen ze steviger aan dan de standaardmodellen die we eerder gebruikten.
Connettori circolari ben realizzati. Li utilizziamo sui nostri macchinari industriali: l’accoppiamento è preciso e il corpo del connettore è robusto. Il rapporto qualità-prezzo è competitivo.
De här IP68-klassade kontakterna känns robusta. Vi använder dem i krävande utomhusmiljöer och har inte sett något vattenintrång vid normal användning. Supporten svarade snabbt på våra tekniska frågor.
Feedback may be lightly edited for clarity. Product performance depends on correct product selection and installation. For photovoltaic systems, use only connector combinations approved by the relevant manufacturers and system documentation.
