Which statement about the combiner 3's built-in Envoy is true?

• A. It requires a separate Envoy module for monitoring
• B. It has a built-in Envoy
• C. It uses Wi-Fi for communications
• D. It cannot monitor PV production

Answer: (B)

Combiner 3 includes its own Envoy gateway, so the data-collection and monitoring bridge is built right into the box. That integration means you don’t need a separate Envoy module to monitor the system—the combiner box handles gathering inverter data and transmitting it to Enlighten. The connection is typically through a wired network, enabling reliable monitoring of PV production and system status. So, the statement that it has a built-in Envoy is the correct one, while the others don’t fit because the box can monitor production and doesn’t rely on a separate module, and it isn’t defined by Wi‑Fi be default.
