Enphase IQ Gateway
The IQ Gateway, formerly the Envoy, is the brain that ties an Enphase system together and gets it online. It collects panel-level production data, supports optional whole-home consumption metering, and reports everything to the Enphase app over Wi-Fi, Ethernet, or cellular. Every Enphase microinverter or battery install needs one to enable monitoring and remote management.

EG4 Ethernet Adapter
This is EG4's wired monitoring adapter (part EG4SP18KDLETH), the small box that carries your inverter's data to the EG4 app over a network cable instead of WiFi. It plugs into the inverter's monitoring port, and a standard RJ45 Ethernet line runs from the cable gland on its body back to your router. Three status lights sit on the face so you can read the connection at a glance: INV for the link to the inverter, a cloud light for the reach out to the EG4 portal, and IP for its network address. There is a reset button, and the unit mounts to the inverter with its built-in faceplate. It works across the EG4 inverter line, the 3k Off-Grid being the exception. The reason to run this over the WiFi dongle is that a cable does not drop. If the inverter lives in a garage, a shop, or a back corner where the WiFi is thin, a wireless adapter that keeps falling offline leaves gaps in your history and an app that shows nothing right when you want a look. Wire it straight to the router and the link stays up, so the numbers keep coming in. If there is a network jack anywhere near the inverter, this is the steadier way to keep eyes on the system.

EG4 Indoor Conduit Box Top Plate (100Ah WallMount)
This is EG4's indoor conduit box for the 100Ah WallMount battery and the 6000XP off-grid inverter. It gives the wiring between the two a clean, enclosed run instead of leaving cable out in the open. The box measures 17.8 inches long, 7.08 inches wide, and 7.9 inches tall, and it ships as a kit with the plates, screws, and parts to put it together (model EG4SP48V100AHIDWMBCNDTBOXV1). The part that earns its keep is the matching knockouts on both the left and right plates, so you can bring conduit in from whichever side lines up with your wall and panel. You build it to fit the install rather than working around one fixed opening. Pair it with the WallMount battery and the 6000XP and the finished wall reads like a real electrical job instead of a pile of loose cable.
