What "not reporting" actually means
Every panel on an Enphase system has its own microinverter underneath. Those micros send their data to a small box in your house or garage, the IQ Gateway (older systems call it the Envoy). The gateway sends everything to the Enphase app.
When the app marks a micro as "not reporting," the gateway is telling you it lost contact with it. That can happen because: - The micro stopped working. - The micro is working but can't talk to the gateway. - The circuit that feeds a group of micros is down, so none of them have power.
Those three have very different fixes. That's why it's worth checking before anyone climbs on the roof.
First: is it daytime?
Micros only run when the sun hits the panels. At night, or very early on a cloudy morning, they go to sleep and the app can show them as not reporting. That's normal. Check again around midday on a sunny day before you worry.
Look at the pattern in the app
Open the array view in the Enphase app and look at which panels are dark.
One panel dark, the rest fine. That points to that single micro, or the connection right at that panel. It can be a failed micro or a loose or damaged connector.
A whole block dark, side by side. This is the one we see a lot. When several micros in the same section stop at the same time, it's rarely bad luck with every one of them. Usually something in the branch circuit that feeds them is down: a tripped breaker, a failed cable or jumper, or a bad connection.
Everything dark. Most of the time the gateway itself lost internet. New router, changed Wi-Fi password, the gateway got unplugged, or the outlet it's on lost power. The panels can be producing just fine while the app shows nothing.
A real one from Winter Haven
A homeowner called us because a whole section of her system, 7 micros in a row, had gone dark in the app. The rest of the roof was producing normally.
We lifted the panels on that section and followed the circuit. The problem wasn't the micros. The connector on the AC jumper feeding that branch had melted. When that connection fails, every micro after it loses power, so the app shows all of them as not reporting at once.
We made the circuit safe that day. On the return visit the jumper was replaced, the circuit was reconnected, and all 7 micros came back in the app. If we had started swapping micros, she would have paid for parts she didn't need, and the problem would still be there.
A melted connector is also a reason not to wait. It means heat built up at that point. It's not something to leave for months.
What you can check from the ground
- The gateway. Find the Enphase box (usually near your electric panel or in the garage). Check that it's plugged in and has power. If your internet changed recently, that's a strong clue.
- The breaker. Look at the solar breaker in your main panel or in the solar combiner box. If it's tripped, you can reset it once. If it trips again, stop and call someone. Repeated tripping means something is wrong.
- The date it started. In the app, go back day by day and find when the panels went dark. Did it happen after a storm? After roof work? After a power outage? That date saves a lot of time on the diagnostic.
- Screenshots. Take a screenshot of the array view showing which panels are dark. Send that when you call.
What not to do
Don't go on the roof and don't unplug panel connectors. Enphase connectors aren't meant to be pulled apart by hand while the system is live, and a damaged connector is often what caused the problem in the first place. Don't open the combiner box or the gateway beyond looking at the lights.
If a micro really failed
If the diagnostic shows a micro is the problem, Enphase has a replacement process for failed units, called an RMA. Whether your unit qualifies depends on the model, its age, and Enphase's own terms, so we check that with you before any work. That process goes through the manufacturer, not your installer, which matters if the company that installed your system is gone.
If your installer closed or stopped answering, our solar diagnostic and repair service is built for exactly this. We work on systems no matter who installed them, including here in Winter Haven. If your system came from a company that went bankrupt, our Sunnova guide covers the paperwork side.
Permitted, electrical, and roofing work is performed in coordination with our licensed contracting partner.
