About this product

Low-Profile Solar · Maximum Harvest · Weight-Sensitive Builds
✓ Multi-Panel Flexible✓ Array Cabling✓ MPPT Controller✓ Bluetooth Monitoring✓ Lightweight
Multiple semi-flexible panels with matched MPPT controller and array cabling — full solar coverage without the bulk

Use the sun to charge your leisure battery with the harvest of a multi-panel array — without the height, weight, or wind resistance of rigid panels. Two to four 150W semi-flexible panels mount flush to the roof, connected through a SmartSolar MPPT controller sized for the array's combined output. Panels, controller, array cabling, roof-entry hardware, and a PV isolator in one kit (excluding fixings and adhesives/sealants).

For elevating roofs, curved surfaces, and vans where aesthetics matter as much as amps, this is the way to get serious solar charging. Each panel weighs kilos, not tens of kilos — and nothing protrudes above the roofline.

The kit arrives matched: panels, controller, array cabling with series connections, and the roof-entry hardware. Design it once on the roof, wire it up, and the MPPT controller reports the total harvest live to your phone — with the last 30 days of history in the VictronConnect app.

  • 2 or more 150W semi-flexible panels — your chosen count
  • SmartSolar MPPT controller sized for the combined array
  • Array cabling with series connections and inline fusing
  • Bluetooth monitoring of total array harvest — live and 30 days of history in the VictronConnect app
  • Low-profile — nothing above the roofline
  • Lightweight — suitable for elevating roofs and pop-tops
  • PV Isolation included as standard
  • Optional MC4 internal cutoff — rooftop connectors as standard, or our internal connector service for a clean pass-through cable entry

📦 What's Included

1

150W Semi-Flexible Solar Panels

  • Your chosen count of lightweight, low-profile panels. Mount flush with adhesive or mechanical fixings (not supplied).
2

SmartSolar MPPT Controller

  • SmartSolar MPPT matched to the array — 100/30 for two or three panels, 100/50 for four. Harvest every panel's output properly.
3

Array Cabling Kit

  • Series connections between panels, MC4 connectors, roof gland, inline fusing per string.
4

Roof-Entry Hardware

  • Cable glands for a watertight pass-through.
5

Solar PV Isolator (DC Breaker)

  • A DC breaker handles isolation and circuit protection in one unit. Switch your solar charge off when storing lithium batteries or for system maintenance.

⚡ Key Features

01Array Harvest Without the Array Look

Two, three, or four flexible panels give you 300-600W of harvesting, all sitting flush with the roofline. You get serious charging power with the silhouette of a standard van.

02Controller Sized for the Full Array

The MPPT controller in this kit handles the combined current of all your panels — not a single-panel controller hoping to keep up. Harvest gets converted, not clipped.

03Weight-Safe for Elevating Roofs

Multiple rigid panels can exceed the mechanism's weight allowance. Multiple flexible panels deliver the harvest without the mass.

04Monitor the Array, Not a Guess

Bluetooth in the controller shows total array output live. See the effect of shade, tilt, and season on your actual harvest numbers.

❓ FAQ

How many flexible panels do I need?

For a fridge plus normal 12V loads, 2 panels (300W) cover summer well. Full-time off-grid with an inverter — 3 or 4. Flexible panels cost slightly more per watt than rigid, so rigid is better value if weight and height aren't concerns.

Do flexible panels get hot?

Yes — mounted flush to a dark roof, they run hotter than rigid panels on brackets. MPPT control recovers most of that loss. In very hot climates, rigid panels with airflow underneath are more efficient; in UK conditions, the difference is minor.

Is the cabling different from a single-panel kit?

Yes — the panels connect in series down a single cable run to the controller, with inline fusing per string. It's all pre-matched to the controller's rating.

Can I mix flexible and rigid panels?

It's not recommended — different electrical characteristics mean the MPPT controller can't track both panels' maximum power points simultaneously. Pick one type for the whole array.
