Some of the modules in my app say NC, what does that mean?

NC means “Not Communicating”. Rest assured, your modules are still producing power, but the micro-inverter has lost its connection to your ECU (Energy Communication Unit). This does happen from time to time, and will often correct itself after 24-48 hours.

If the issue persists for longer than 48 hours, please email us at for Calgary and for Edmonton so we can investigate the issues further.
