When setting up a layout that requires multiple power supplies, it’s important to understand that power flows through the system in a way that is entirely dependent on how you connect your panels to each other.
Your Canvas system is designed to protect against all conditions that may lead to failure, including electrical problems and potential safety hazards. The system is designed to detect where you have placed panels and power supplies, and then optimize the overall system to protect the weakest link.
To simplify setup, we strongly recommend using either 25W power supplies or 75W power supplies. This reduces the likelihood of inadvertently placing power supplies in a manner that provides for poor system performance.
The Power Diagnostic tool in the app will help you progressively place or optimize the locations of your supplies, although they work best when you are using a single type of power supply.
If you do not have the option of using a single power supply type, try the following strategies to optimize your placement:
- 25W supplies should supply one side of the layout, 75W supplies the other
- Roughly separate the layout depending on the total power of 25W versus the total power of 75W supplies
- Connect a 75W supply where the layout should be separated
- Distribute all other supplies as evenly as possible
A good rule of thumb is to plan for each panel to draw 1 watt of power (this is the maximum electricity each panel could draw, though will likely be lower in practice).
We’ve included a simplified diagram of what a linear layout could look like with this strategy below:
Note that mixing power supplies and experimenting with different placement locations is completely safe, it just may result in the system reducing its overall brightness levels to ensure safe operating conditions.
