Routing MC4 Connectors Through the Roof – Without Special Tiles

🔧 Introduction

Do you want to connect your solar system or a balcony power plant – but the MC4 connectors don't fit through the roof?
Many instructions recommend cutting off the connectors or installing expensive special tiles. But there's a much easier way.

We'll show you how to get your MC4 solar cables through the tiled roof quickly, safely, and without drilling – thanks to our clever DIY roof duct.

🛠 Problem: Standard solutions are expensive or complicated

With a classic tiled roof, there are three common problems:

1. MC4 connectors are too thick for common cable glands

2. Special tiles are expensive and require professional adaptation

3. Drilling damages roof skin or tiles – risk of water damage

Especially for DIY enthusiasts or rental properties, this is an unnecessary effort – there's a smarter way.

✅ The Solution: Side clip-in roof duct from NEXCAPE

Our weatherproof PV cable duct was specially developed for DIY projects.
Highlights:

• ✔️ Protects the solar cable from abrasion at the tile edge – no fraying of the insulation over the years (the actual purpose)

• ✔️ MC4 connectors remain mounted – no disassembly required

• ✔️ Side guide slots – simply insert & clip in cables

• ✔️ No special tiles – fits under standard tiles

• ✔️ Weatherproof & UV-resistant – for long-term safety

💡 Ideal for:

• Balcony power plants

• Garden sheds

• Carports

• Single-family homes
