⚙️ Hardware Setup, Adjustments & FAQs

❓ How to check if the fuse is good without removing it? cfg_01
Most MC4 inline fuse connectors do not allow visual fuse checking without removal. To test continuity, a multimeter set to resistance (Ohms) is needed. Measure resistance between the fuse terminals. A reading close to zero indicates the fuse is intact.

⚖️ Seller Warranty & Marketplace Dispute Conciliation

Contact the seller's warranty and marketplace return policy if, after following all usage and troubleshooting instructions, the connector exhibits a manufacturing defect, such as cracks in the plastic body without external impact, persistent sealing failure despite correct connection, or if the internal fuse blows repeatedly without any apparent cause of overload or misuse. These indicate a manufacturing defect that prevents normal product use.
