Renogy 20A Waterproof In-Line Solar Fuse Holder

Renogy 20A Waterproof In-Line Solar Fuse Holder (with Fuse)

The Renogy 20A Waterproof In-Line Fuse Holder is a 20A fuse embedded in a waterproof holder, featuring male and female connector leads on each end. Designed to provide complete single-circuit protection to your solar power array, the fuse prevents large currents from damaging your solar panels — essential extra protection for any PV system.

Complete Single-Circuit Protection

Fitted inline between your solar panel and charge controller, the pre-installed fuse guards a single string against overcurrent, protecting your panels and wiring from damage and reducing fire risk.

Waterproof, Plug-and-Play Design

IP67 waterproof protection and auto-locking male/female connectors make for easy, reliable connections. It’s compatible with PV cables of different insulation diameters and designed for a wide range of DC applications — simple plug-and-play installation with standard solar panel leads and adapter kits.

Built for Safety & Durability

Silver-plated copper contacts deliver high current-carrying capacity, PPO insulation material resists heat, and Protection Class II construction adds electrical safety. The replaceable fuse means you can service the holder rather than replace it.

Important Safety Note

For protection against electric shock, PV connectors must be isolated from the power supply while being assembled or disassembled. Do not unplug the connector under load — place it in a no-load state first by switching off the DC/AC converter or breaking the AC circuit. Protect disconnected connectors from dirt and water with sealing caps.

Protect your solar array the simple way with the Renogy 20A Waterproof In-Line Solar Fuse Holder — IP67-rated, 1000V DC single-circuit overcurrent protection that plugs straight into your panel leads.
