Place your panel where the sun is – and your inverter where it makes sense.
This DC extension cable pair adds extra length between your solar panel and the micro-inverter, so you can position your Solarfy kit exactly where it performs best: further down the garden, on the far side of a flat roof or away from shade.
🔌 Plug & play
MC4-compatible connectors simply click into place – no tools, no electrician needed.
🌦️ Built for British weather
UV-resistant, double-insulated solar cable with weatherproof connectors for permanent outdoor use.
✅ Made for Solarfy
Fully compatible with Solarfy Solo and Solarfy Duo and the Hoymiles HMS-800-2WB inverter.
What's in the box
- 1 × positive (+) extension cable with MC4-compatible connectors
- 1 × negative (–) extension cable with MC4-compatible connectors
One pair extends the connection of one solar panel. Available in 2 m, 5 m and 10 m.
Which length do I need?
| 2 m | A little extra reach – e.g. to tuck the inverter behind the panel frame or next to a wall. |
| 5 m | Ideal if the panel sits on a lawn, patio or flat roof a few metres from the inverter. |
| 10 m | For larger gardens or when the sunniest spot is well away from the house. |
Tip: Measure the route the cable will actually take (along the ground, around corners) and add a little slack. Running a Solarfy Duo with both panels further away? Simply order one pair per panel.
