Which of the following is true about activation in the installation process?

• A. Activation connects the site to Enlighten
• B. Activation wires the DC into the grid
• C. Activation is optional for most systems
• D. Activation is not used in standard installations

Answer: (A)

Activation is the provisioning step that links the physical solar system to Enphase Enlighten, the cloud monitoring platform. When you activate, the system’s hardware (inverters, gateway, etc.) is registered to the correct site and installer in Enlighten, and data flow begins so you can monitor production, receive alerts, and manage the system remotely. This makes activation essential for visibility and ongoing service, not optional. It’s not about electrical connections like wiring the DC into the grid—that happens during electrical interconnection and is separate from the activation process. Standard installations include activation as a normal, required step to commission and monitor the system, so connecting the site to Enlighten is the correct description.
