About this item
The IQ Combiner 5C is Enphase's all-in-one combiner panel. It holds up to four PV branch circuit breakers, hosts the IQ Gateway for system monitoring and grid-tie control, and provides the wiring point for the rest of the IQ stack. One box replaces a separate AC combiner, a separate revenue meter, and a separate monitoring gateway.
The pre-wired internals are what save install time. Production CT clamps are factory-installed, the Gateway slot is hardened for indoor or outdoor mount (NEMA 3R rated), and the branch circuit positions are sized for the breakers Enphase microinverter strings need. Mount it adjacent to the main service panel, run AC out to the panel, run microinverter trunk cables in.
For storage-equipped installs, the Combiner pairs with the IQ System Controller 3 (handles the backup/grid switch) and the IQ Battery 5P (modular storage). For monitoring-only installs, the Combiner alone with microinverters gets you per-module production data through the Enphase app. NEMA 3R outdoor mount, 5-year Enphase warranty.

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.
