“Microinverter not reporting” means a panel’s microinverter has stopped sending data to your gateway. It does not, on its own, mean the panel has stopped producing: Enphase says the condition “does not always mean your system has stopped producing power”. If every panel went black at once, check the gateway first: when it is offline, every microinverter shows as not reporting while production carries on. One panel or a few can be anything on Enphase’s list below, from snow to a tripped breaker to, rarely, a faulty microinverter. Before you escalate, Enphase asks you to “allow up to 24–48 hours for the status to update”.
One panel, some panels, or all of them
Open the Enphase App, go to the ARRAY tab and count. Affected panels show as black. That count is the first thing to write down:
| What you see on ARRAY | What it can mean |
|---|---|
| Every panel black at once | Check the gateway first: when it is offline, every microinverter appears not reporting while production can carry on |
| A cluster or a scattered few black, others reporting normally | Any cause on the list below |
| One panel black, everything else current | Any cause on the list below, including wiring or equipment issues and, rarely, a faulty microinverter |
Enphase’s own list of causes:
Common causes include: Low-light conditions caused by heavy cloud cover or snow · Electrical interference on the power lines · A gateway connected to an unsuitable outlet or moved from its original location · A tripped circuit breaker · Wiring or equipment issues · A faulty microinverter in rare cases
All microinverters not reporting: check the gateway first
If the whole array went dark at once, the question is whether your system stopped producing or stopped talking. These are different problems with different urgency, and Enphase’s documentation is explicit that the second one can look exactly like the first:
If the gateway is offline, all microinverters may appear as ‘not reporting’ even if production continues.
The owner-visible name for the comms failure is Gateway Not Reporting (the IQ Gateway is Enphase’s own communications device, the box that reports your system to the cloud): “If your gateway loses its internet connection, an error notification appears in the Enphase App, showing a Gateway Not Reporting alert.” That is an internet-connection problem at the gateway. Your panels may well be producing into the house the whole time you are staring at a stale app.
Two other items on the list are cheap to clear before you call anyone: a tripped circuit breaker on the solar circuit, and the gateway having been connected to an unsuitable outlet or moved from its original location.
The general question of separating “no data” from “no production” is the same one for every brand, and is worked through step by step in the inverter offline triage guide.
The four IQ Gateway LEDs — not one light with several colours
The IQ Gateway and Envoy-S carry four separate LEDs, each of which can show several colours, and a red on one of them means something quite different from a red on another.
| LED | State | Meaning |
|---|---|---|
| Network communications | solid green | connected to Enphase Cloud |
| flashing green | connecting to cloud or Wi-Fi router | |
| amber/red | local network only (no internet) | |
| off | no network available | |
| AP mode | solid green | AP mode enabled, gateway Wi-Fi available |
| Power production | green | all communicating microinverters producing |
| flashing green | microinverter upgrade in progress | |
| amber/red | at least one microinverter not producing | |
| off | not communicating (low light / night) | |
| Device communications | solid green | all microinverters communicating |
| flashing green | device scan in progress | |
| solid amber/red | at least one device not communicating | |
| All four | flashing red in unison | booting (about 3 minutes) |
| flashing green sequentially | software update in progress |
Read that table against your symptom. An amber or red network LED with a green device communications LED is a house-internet problem: the gateway is still hearing every microinverter, it simply cannot reach the cloud. An amber or red device communications LED is the opposite: the internet is fine, but at least one device is not communicating.
All four LEDs flashing red is the boot sequence; if it carries on for longer than 30 to 60 minutes, Enphase says to power cycle the gateway once. The device-scan button starts a 15-minute scan, so the device-communications LED flashing green for a quarter of an hour after someone pressed it is not a fault.
If you can reach the gateway on your own network, its local page at http://envoy.local/home renders counts in the form 12 Detected / 12 Communicating / 12 Producing Power: three separate numbers, which tell you far more than any single status word. On the older Envoy with an LCD, the same distinction came down to two characters: “+Web indicates successful reporting to Enlighten. -Web indicates that the Envoy is not reporting data to Enlighten.”
One microinverter not reporting: the ARRAY tab and the black panel
A single black panel is the hardest case to judge, because black on the ARRAY screen means “no data from this microinverter”, not “this panel is dead”. Low light from heavy cloud cover or snow is first on Enphase’s own cause list, and a quiet microinverter looks identical to a broken one in the app.
What separates them is time and weather. Look again at midday on a clear day, after the 24–48 hours Enphase asks for. A panel that is still black while its neighbours are reporting current values, in full sun, days later, is no longer explained by the low-light entry on Enphase’s list. What is left on that list is wiring or equipment issues and “a faulty microinverter in rare cases”. Take it to your installer.
If you never think to look, a single dead panel can sit unnoticed: it is the exact failure Enphase’s alerting is designed not to interrupt anyone about.
Microinverters not reporting after snow, and the other weather false alarm
The first entry on Enphase’s cause list is “Low-light conditions caused by heavy cloud cover or snow”: covered panels drop off the array view and come back when they clear. Under snow you can lose panels to “not reporting” while nothing at all is broken. Whether that snow is worth clearing, and what a fully covered day costs, is worked through in snow on your solar panels: leave it or clear it. On the gateway, the power production LED is off in low light or at night. Amber or red on that same LED is the one that means at least one microinverter is not producing.
Put a date on it: snow melts and cloud passes, and a fault does not. That is what the documented 24–48 hour status window is for, and it is also why a snow week is exactly when a real fault can hide.
Electrical interference on the power lines
Enphase lists “Electrical interference on the power lines” as a cause of not-reporting in its own right, and separately the gateway being on “an unsuitable outlet” or having been “moved from its original location”. Both are ordinary and cheap to rule out: confirm the gateway is on its original outlet and on a circuit that has not changed.
12 hours, 10%, five days: what Enphase actually notifies you about
Enphase publishes its alert thresholds, and they are unambiguous:
- Warning: at least one microinverter not reporting for 12 hours during daylight. This is in-app only. There is no push.
- Error: at least 10% of microinverters not reporting for five consecutive days. Only at that point, in Enphase’s words, “homeowners and installers will be notified via text, email, or push notification, depending on their selected preferences”.
Read the second rule with your own panel count to hand. Enphase’s own worked example is an 11-panel site: one silent microinverter for five days is 9%, below the 10% bar, so it stays a Warning and no notification is ever sent. A 20-panel site needs two dead panels before anything is pushed; 30 panels needs three. And the fastest this rule can reach your phone at all is five days, because the 12-hour rule produces a status change, not a message. Those numbers govern the microinverter rule only. For the gateway, what is documented is different in kind: the Gateway Not Reporting alert appears in the app when the gateway loses its internet connection.
Enphase explains the reasoning itself, and says plainly who the alerting was built for:
Alert emails… are batched so they can be addressed with a single service call… A single panel that is not producing has minimal impact on the production of the array in total. By batching service calls, impacts to installer workday schedules are minimized.
That is a defensible engineering position from the installer’s side of the van, and it is a design in which your single dead panel is not worth a message. Enphase is direct about the tier split too: “Per-panel alert notifications are one of the benefits of the Enphase Installer Portal.”
An owner asked for the missing piece in Enphase’s own community, and got a reply from the company:
Could the envoy provide a push notification to i.e. my mobile phone or E-mail adress in case of a ‘system not reporting’ malfunction ? This would be vey helpful since my system sometimes goes down (partially) without me knowing so.
The push notification feature request has been shared with our development team.
Where your own settings live: Menu → Account → My Notifications in the Enphase App. The channels are Email, Text and Push, and texts need a registered mobile number. It is worth ten minutes, alongside the same audit for the other brands, set out in who actually gets your solar alerts.
Envoy or IQ Gateway, Enlighten or Enphase App
Both sets of names are still in use, Enphase included. The official rename table is: IQ Envoy → IQ Gateway; Enlighten Manager → Enphase Installer Portal; Enlighten App → Enphase App; Encharge → IQ Battery; Enpower → IQ System Controller. Enphase’s own support copy still carries both, in article titles such as “What do LEDs on the IQ Gateway or Envoy S mean?”.
The tier changes your diagnosis more than the hardware name does. Envoy Not Reporting is an alert type in the Maintenance Alerts widget and Systems Status filter of the Installer Portal, the fleet tool. In the app on your phone, the equivalent conditions are Gateway Not Reporting, Microinverter Not Reporting (singular, as an app alert) and Microinverters Not Reporting (plural, as a system status). The same underperformance condition is called Production Issue in the Installer Portal and Low Solar Production in the Enphase App.
Background on the platform itself is on our Enphase monitoring page.
Normal, Warning, Error: the health states Enphase documents
The Enphase App shows one of three health states: Normal, Warning and Error. If what you are looking at is a status word, match it against those three.
Two more strings that get confused with this one. Meter Not Reporting is about communication between a revenue-grade meter and the gateway, and is unrelated to whether your panels are producing. And Low Solar Production (the app-side name for Production Issue) is an underperformance alert, not a not-reporting alert; Enphase’s remedy article for it says to monitor “for the next 24–48 hours” and then to “call your Enphase installer”. If your problem is that output looks low rather than absent, the method for putting a number on it is in solar panels producing less than expected. The comparison itself, your output against what the weather should have produced, is in check your solar production against the weather.
If it is still not reporting after 48 hours
By then the weather explanations are spent, and the question becomes who is looking. Note how many panels are black on the ARRAY tab and which of the four gateway LEDs is amber or red, and take both to your installer. That pairing tells them in one sentence whether to expect a comms problem or a hardware one.
If you no longer have an installer, or the account was set up in their name, the access problem comes first: the general checks any owner can run do not need anybody’s portal, and the section above shows where your own notification settings sit. Or let Solmiro do the watching: every day it works out what the weather over your roof allowed, and it e-mails you when production falls well short of that or stops. Connecting is free.
Questions owners ask
Does one microinverter not reporting mean that panel is dead?
Not by itself. Enphase says a Microinverters Not Reporting condition means some or all of your panels are not sending data to the gateway and 'does not always mean your system has stopped producing power'. Its published cause list runs from low light and snow through powerline interference and a tripped breaker to 'a faulty microinverter in rare cases'. One panel still black on the ARRAY screen at midday on a clear day, days after everything else recovered, is the case worth escalating.
What do four red lights on an Enphase Envoy or IQ Gateway mean?
There are four separate LEDs, and all four flashing red in unison is the boot sequence, which takes about three minutes. Enphase's own guidance is that 'if all LEDs continue to flash red for longer than 30-60 minutes, then try to power cycle the gateway once'. All four flashing green in sequence is a software update, not a fault.
Why do my Enphase microinverters show not reporting after snow?
Because low light is on Enphase's official cause list: 'Low-light conditions caused by heavy cloud cover or snow'. Covered panels drop off the ARRAY screen and come back when they clear. Enphase's LED documentation gives the power production LED as off when the gateway is not communicating with the microinverters, which is what low light or night looks like on the hardware. Allow up to 24–48 hours for the status to update before treating it as a fault.
Will Enphase send me a push notification if one microinverter stops?
Almost certainly not — unless that one panel is 10% or more of your array. The documented thresholds are a Warning in the app after at least one microinverter has been silent for 12 hours during daylight, with no push, and a notification by text, email or push only when at least 10% of microinverters have been silent for five consecutive days, and then 'depending on their selected preferences'. Enphase's own worked example is an 11-panel site: one silent microinverter is 9%, below the bar, so it stays a Warning.
What is the difference between Envoy Not Reporting and Gateway Not Reporting?
Gateway Not Reporting is the alert you see as an owner: 'If your gateway loses its internet connection, an error notification appears in the Enphase App, showing a Gateway Not Reporting alert.' Envoy Not Reporting is an alert type in the Maintenance Alerts widget and Systems Status filter of the Enphase Installer Portal, the fleet tool your installer uses, not the app on your phone.
