Enphase Cell Modem-07-INT-05
Enphase IQ communications — One connects the battery to the gateway, the other connects the system to the internet.
An Enphase system has two communication problems and these are the two answers.
About the Enphase IQ communications
Inside the installation, the IQ Gateway Metered has to talk to the IQ Battery 5P. The Communications Kit 2 is the wired way of doing that, using control cables rather than depending on anything wireless — which is the right choice wherever the two are far apart or the building is unhelpful.
Outside it, the system has to reach Enphase. The Mobile Connect cellular modem provides that over high-speed cellular, with a five-year pre-paid data plan and multiple network options, so it falls back rather than failing when one network is weak.
What does this fit?
This is how an Enphase system talks internally and to the outside world.
Two different links. The Communications Kit 2 is the wired connection between an IQ Gateway Metered and an IQ Battery 5P, using control cables. The cell modem is the system's route to the internet where broadband is not available.

What the job needs
The details that decide whether this suits the system:
- The Communications Kit 2 INT enables wired communication between an IQ Gateway Metered and an IQ Battery 5P using control cables.
- The CELLMODEM-07 provides high-speed cellular connectivity with a five-year pre-paid data plan and multiple network options.
- The IQ System Controller 3 already bundles a cell modem — check before ordering a second.
Where this earns its place
Each part solves a different communication problem.
