Solar Mesh Node Overview

PCW has commissioned and deployed solar mesh nodes designed by Holobiont Lab. See their meshbox docs for info on how they build these solar-powered wifi access points.

Deployments

PCW installed a solar mesh node in Norris Square Neighborhood Projects Colobo Gardens in 2021, and it only recently needed to be fixed with a replacement battery. Here are a few photos of what the setup looks like.

Troubleshooting Solar Mesh Nodes

For additional troubleshooting help, check out the 'Troubleshooting' section (pg. 12) of the Meshbox Documentation.

Common issues include:

  • Battery Discharge - the battery should read between 12.5V > 14.6V.
    • Anything less than 12.5v and the battery management system will shut off to save power.
  • Connections between the enclosure and the charge controller, as well as the connections between the charge controller and AP.
    • There should be a red light on the charge controller, and a green light on the PoE injector.
  • Low temperature or bad weather conditions
