About this product

Low-Profile Solar + Distribution · One-Kit Install
✓ Flexible Panel + Power Board✓ Pre-Wired MPPT✓ Low-Profile✓ Bluetooth✓ UK-Assembled
150W semi-flexible solar panel PLUS the Isolated Solar PV Power Board — low-profile solar charging and pre-wired 12V distribution

Use the sun to charge your leisure battery without anything above the roofline. This kit combines our low-profile 150W semi-flexible solar panel with the Isolated Solar PV Power Board — everything you need for flush-to-the-roof solar charging and pre-wired 12V distribution in one kit (excluding fixings and adhesives/sealants).

The panel mounts flat with nothing above the roofline. The board arrives pre-wired with the MPPT controller, fusing, and busbars already installed and tested. You mount the panel, run the cable, connect your battery and loads, and the system works.

For elevating roofs, curved surfaces, and vans where a rigid panel is wrong but solar charging is essential — this kit does the job without compromise.

  • 150W semi-flexible panel — low-profile, lightweight
  • Isolated Solar PV Power Board with pre-installed MPPT controller
  • Board pre-wired, pre-fused, and tested in the UK
  • Bluetooth monitoring via VictronConnect app — live and 30 days of history
  • Solar cabling kit and mounting hardware included — fixings and sealant not supplied
  • Suitable for elevating roofs and curved surfaces
  • Optional MC4 internal cutoff — rooftop connectors as standard, or our internal connector service for a clean pass-through cable entry

⚡ Key Features

01Solar Where Rigid Won't Go

The flexible panel conforms to curved surfaces and sits flush — you get real solar charging where a rigid panel would be impossible or ugly.

02Pre-Wired Board Saves the Installation

MPPT controller, fusing, and distribution are on the board, wired and tested. Your job is running cable and connecting terminals.

03Expandable From Day One

The board accepts a split charge input and additional 12V circuits. Start with solar, add alternator charging later, all through the same board.

04Bluetooth Feedback

See the panel's harvest live in the VictronConnect app — verify the install works the moment you connect.

❓ FAQ

Why flexible instead of rigid here?

Weight and height. Elevating roofs and pop-tops have weight limits; curved roofs can't take rigid frames. The flexible panel delivers 150W with none of those constraints — at a small efficiency cost in hot weather.

Can I add more panels later?

Yes, if you choose the 30A board variant — it has controller capacity for a second panel. Check with us on the controller's sizing for your planned expansion.

How does the board differ from a loose MPPT controller?

The board mounts and wires the controller with fusing, busbars, and distribution terminals as one tested unit. A loose controller is just the regulator — you still need to buy, mount, and wire everything else.

Is the installation harder than a standard kit?

No — simpler. Fewer separate parts to mount and wire. The board is the heart of the system and arrives ready to connect.
