A good 12V canopy panel starts on paper, not with a drill. Before choosing sockets or cutting a panel, map every power input, output and control cable. That simple step helps prevent crowded connectors, crossed circuits and expensive rework.
This guide focuses on the physical layout and connection points. Cable sizing, protection and final wiring should be checked against the equipment manuals and completed or reviewed by a qualified auto electrician.
1. List every circuit
Write down what the canopy must power today and what you may add later. Separate inputs from outputs so a charging lead cannot be mistaken for an accessory outlet.
| Circuit | Direction | Typical label | Connection idea |
|---|---|---|---|
| Portable solar | Into the system | SOLAR IN | Dedicated two-pole connector |
| Vehicle or DCDC feed | Into the system | DCDC IN | Two-pole or specified three-pole connector |
| Fridge power | Out to appliance | FRIDGE | Dedicated accessory outlet |
| Compressor | Out to appliance | AIR | Connector sized for the designed circuit |
| Lighting or controls | Low-current multi-wire | LIGHTS | Deutsch DT where appropriate |
| Starlink network | Data | STARLINK | RJ45 passthrough plus separate power |
2. Decide where the panel will live
The ideal position is easy to reach, protected from cargo and clear behind the panel. Common locations include the rear canopy wall, an internal electrical board, a drawer face or a protected side panel.
Check behind the proposed location for:
- Structural ribs and folded panel edges
- Existing wiring, fuel or water lines
- Connector bodies and terminal depth
- Cable bend radius and strain relief
- Access for tools, fuses and future servicing
- Doors, drawers and fridge slides through their full travel
Use the steps in our Anderson plug canopy mounting guide before marking the final cut-out.
3. Group circuits by purpose
A panel is easier to understand when inputs sit together and outputs sit together. Keep network/data connections visually separate from power. If several same-size connectors are used, distinguish them with colour keying and labels.
For a compact build, a common layout is:
- Left: solar or vehicle charging input
- Centre: fridge or general accessory output
- Right: spare, compressor or future circuit
There is no universal order. Consistency and labelling matter more than copying another vehicle.
4. Choose single, double or triple mounts
A single mount suits one dedicated connection and can fit into a tight location. A double mount groups two related circuits without making the panel crowded. A triple mount works well for more developed touring systems, provided there is adequate cable clearance behind it.
- Single Anderson plug surface mount
- Double Anderson plug surface mount
- Triple Anderson plug surface mount
If your panel combines Anderson and Deutsch connectors, the Build Your Own Surface Mount option lets you create a layout around the actual circuits rather than forcing the wiring into a standard arrangement.
5. Plan labels before ordering
Good labels describe function and direction. POWER is vague; SOLAR IN and FRIDGE OUT are clearer. Keep labels short enough to read at a glance and use the same wording on wiring diagrams and cable markers.
Useful labels include:
- SOLAR IN
- DCDC IN
- FRIDGE
- AUX OUT
- COMPRESSOR
- TRAILER
- STARLINK
- SPARE
6. Leave room for service and growth
Do not fill every millimetre of panel space. A spare connector position, accessible fuse area and service loop can make later upgrades far easier. Allow enough separation for dust covers and for a hand to grip each plug.
7. Treat the mount as part of the installation
AFS Offroad surface mounts are made in Australia from ASA-GF and include a flexible TPU gasket and stainless mounting hardware. The gasket helps the mount sit neatly against the panel, but it does not make the electrical connector waterproof. Position and cable protection still matter.
Final checklist before cutting
- Every circuit has a defined purpose and direction.
- The connector family and contact size match the electrical design.
- The location is protected and reachable.
- There is enough depth and cable bend clearance.
- Labels are unambiguous.
- Future circuits have been considered.
- The wiring and protection plan has been checked by a competent installer.

Important safety information
Water protection: Dust covers, mounting gaskets and connector mounts discussed in this guide are not waterproof or watertight. Install them in a protected location away from direct spray, high-pressure water and immersion.
Electrical installation: All electrical wiring and installation must be carried out by a suitably qualified electrician or auto electrician, as appropriate. The installer must confirm cable sizing, terminations, fusing, circuit protection and suitability for the application.
