MC4 Inline Diode Connector, 1000V Solar Bypass / Blocking Diode for PV Panels – 10A/15A/20A/30A, IP67 Waterproof, Pre-Wired Plug-and-Play
**Stop reverse current and hot-spot damage — before it starts.**

When one panel in a string is shaded, it doesn't just underperform — it can become a load, heat up, and drain power from the healthy panels. This inline MC4 diode drops straight into your string and gives you a dedicated bypass or blocking diode in seconds, no soldering, no junction box surgery. Just plug it in and the diode does the rest: it blocks reverse current at night and around shading, keeping healthy panels working at full power.

Available in 10A, 15A, 20A, and 30A ratings to match your panel short-circuit current. The housing is the same UV-stabilized PPO and tin-plated copper as our MC4 connectors, sealed to IP67 once mated, rated for -40°C to +85°C and tested to IEC 62852. No heat-shrink, no crimping, no guesswork about diode orientation — the arrow on the body shows you the flow direction.

Sold as one pre-wired inline diode connector (male to female). Choose your current rating at checkout.
MC4 Inline Fuse Holder Connector, 1000V/1500V DC Waterproof PV String Fuse Protector for Solar Panels – 1A to 32A, IP67, IEC 62852
> **Protect every string, panel by panel.**

> A ground fault or a shaded panel shouldn't take down the whole array. This inline MC4 fuse holder drops straight into your PV string and gives each branch its own overcurrent protection — no combiner box, no DIN rail, no extra wiring. Just plug it between the panel and the rest of the string and slide in a standard 10×38mm solar fuse (1A to 32A, your choice). If a fault hits that branch, the fuse blows — and every other panel keeps running.

> The housing is UV-stabilized PPO rated UL94-V0, with tin-plated brass contacts for low resistance and corrosion resistance. Once mated it seals to IP67, so rain, dust, and snow never reach the fuse element. Rated for 1000V / 1500V DC working voltage, tested to IEC 62852, and built for -40°C to +85°C rooftop service. The screw-off end cap makes fuse swaps fast even on the roof — no special tools.

MC4 T-Branch Connector 1 to N, 50A Solar Panel Combiner Manifold for Parallel PV Connection – IP67 Waterproof, No Cable Required, 1000V DC
This T-branch MC4 manifold replaces messy Y-harnesses and field-made parallel runs with a single, factory-sealed junction block. One main feed goes to the inverter or combiner box; N branches plug straight into your panel outputs, so the whole array ties together in minutes. No crimping, no extra extension cable, no waterproof tape — just plug and lock.

Built for real rooftop and ground-mount arrays, the housing is molded in UV-stabilized PPO rated UL94-V0, with tin-plated brass contacts that resist salt spray and high humidity. Once mated the whole thing seals to IP67, so rain, dust, and snow never reach the busbar. The snap-in MC4 locks hold tight against wind-driven panel movement, and the operating range covers -40°C winter install to +85°C summer rooftop heat. TUV tested to 6KV hipot and rated for 50A continuous, 1000V DC.

Available in 1-to-2, 1-to-3, 1-to-4, 1-to-5, and 1-to-6 configurations — order the branch count that matches your string.
MC4 Y Branch Connector Cable 1 to 2, 300mm Pre-Assembled Solar Panel Splitter for Parallel Connection – Male/Female Pair, IP67 Waterproof, 1500V
Skip the crimping tool and the guesswork. This pre-assembled MC4 Y-branch harness lets you combine two solar panels into a single string in seconds — just plug and lock. One male end feeds the inverter or combiner box, while two female ends drop straight onto your panel outputs, so parallel wiring stays clean, neat, and factory-sealed. The 300mm cable gives you enough slack to route around mounting rails without straining the connectors, and the snap-in MC4 locks hold tight against wind-driven panel movement. IP67 sealed once mated, rated for 1000V / 1500V DC at 30A, and built to run from -40°C winter cold to +90°C rooftop summer heat. Sold as a complete 1-to-2 Y harness, ready to install out of the bag.

Tinned-brass contacts shrug off salt spray and high humidity, while the IP67 seal locks out rain, dust, and snow once mated. The snap-in mechanism makes field assembly fast and tamper-proof — no accidental pulls, no loose connections at the busbar. Rated for continuous operation from -40°C to +90°C, molded in UL94-V0 flame-retardant PC/PPO, and tested to IEC 60068-2-52 salt-mist standard. Sold as matched male/female pairs, ready for 4mm² solar cable.
