Enphase Panel Not Reporting — Enlighten Microinverter Fix

One panel in Enlighten is grey — no data, no production. The microinverter for that panel has either failed, lost its AC connection, or the powerline communication signal between it and the Envoy has dropped. The rest of the array keeps generating normally because each Enphase microinverter operates independently.

I have a GivEnergy system consisting of two batteries, two inverters and a controlling EMS (Energy Management System) which has not worked since Nov 2025. After six months I discovered Solar Tech Support, reached out to them and Ron phoned me back – how often do you get that service? Could not be more helpful – worked directly with me over the phone, outside what I would call normal working hours. Lucid explanations and we were able to discuss the issues and history using camera and email history. As this was a very rare setup, Ron was able to access an EMS expert in the field to confirm the solution. One sunny day in, I am now only paying for standing charge and a few pence for spikes in grid consumption while battery catches up with house demand.

When my GivEnergy system had an issue, I was completely left without support and had honestly lost all hope. Thankfully, I searched online and found Ron, which completely turned things around. After sending him a message, he responded incredibly fast and called me to assure me that he would get the problem fixed. I really admire his dedicated, supportive nature and his determination to find a solution. With this kind of outstanding attitude and customer service, he has absolutely secured a future customer in me.

Ron want out of is way to help, nothing was to much. He was very thorough in what he did Very knowledgeable I would highly recommend Ron and his company He did a fantastic job for me. if you have any problems, he'll do his best to help you out and resolve your problem. I wouldn't hesitate to recommend them

Ron took me through a diagnostic to confirm my GivEnergy Inverter had a fault. A common one as it turns out with the AC Inverter. As GivEnergy is defunct there is no immediate fix, aside from sourcing 2nd hand replacement. It may be that a fix becomes available over the summer which would make a lot of GivEnergy customers happy (Again)

Contacted Solar Tech Support in desperation. After explaining the issues I had with my system a diagnosis was made and a solution proposed. Fantastic service, even contacted a manufacturer to arrange replacement parts for me. Great communications, explained all they were doing and what I had to do, clearly and precisly. Followed up to confirm all was ok. Excellent service.

After GivEnergy went into liquidation, just my luck, my battery started playing up (internal board crashed). Contacted my installer - not interested! Found Solar tech support on a Google search. Sooo glad I found this company! Ron is extremely helpful and has plenty of experience. He soon confirmed what the fault was, and helped me to get my system up and running again. Now moved my GivEnergy account to Solar tech support, and will definitely use again if I have more issues. Unusual to find such a helpful company in these times, no morons reading scripts, just direct contact with the engineer.

Contacted Solar Tech Support when trying to understand what my Givenergy inverter problem might be and what might be my options. Received good/honest advise which backed up my thoughts.

Ron is a super star. Two months ago my GivEnergy battery failed a firmware upgrade leaving it a brick. My installer couldn't/wouldn't fix it. GivEnergy couldn't/wouldn't fix it. Then they went into administration and all hope was lost. A flurry of emails later and Ron had diagnosed the fault (failed USB flash drive, something I'd suspected) and talked me through resolving it. Two months of nothing resolved in about 3 hours. It's great to work with someone who pays attention to the details, knows that they're doing (not just following a script) and gets stuff sorted without a fuss or up-charging.

I can add to the list of customers who had already 'given up' on GivEnergy due to their appalling customer service, and that was before they went into administration (their Trustpilot reviews don't lie!). So you can imagine my desperation when, having changed my ISP and my Inverter, predictably, proving to be the only device that didn't connect automatically to my new network, I found zero prospect of any customer support with GivEnergy having called in the administrators just five days earlier! The salvation came from Solar Tech Support. My IT advisor stumbled across their web site and some very helpful tips for beleaguered GivEnergy customers, as well as an offer to provide direct assistance. Nothing ventured, I decided to drop them an E-Mail, with very low expectations based on my experience of GivEnergy customer support. Within an hour Ron had responded with some pin point advice, and after a few exchanges of E-Mails he had nailed the problem, enabling the combined efforts of my IT advisor and solar installer to resolve it and reconnect my Inverter. Thank you Solar Tech Support, and Ron in particular, for coming to the aid of a deserted and despondent GivEnergy customer. Expert, razor sharp advice and first class customer service, even though I wasn't officially a customer.

This company are a rare gem, I had a very unusual problem following a failed firmware upgrade on my GivEnergy kit. I then found out GivEnergy were in administration and had dismissed all their support staff! None of the usual fixes to try and restore my inverter comms would work, and I looked everywhere, forums, GivEnergy youtube support videos - even AI couldn't figure it out. My installer was talking about huge sums for system replacements, and being vague / evasive about if they'd even install replacement GivEnergy inverter. Enter Solar Tech Support, reassuring and knowledgeable from the very start, I've learnt loads about my solar system though the friendly chat while my engineer worked as he diagnosed the problem and figured out a fix procedure that I've not found anywhere else - amazing . If you need solar system repairs - especially if you like me have been left high and dry by GivEnergy, I cannot recommend this company enough. Give them a call.

Andy Thomas · Apr 2026 Trustpilot

I sent a message on their website regarding a problem I have on my Givenergy system. Although not supplied by Ronald, I thought it was worth an email. Within the hour on a Saturday, he phoned and we discussed the problem. He logged in remotely and gave excellent advice. I'm too far away for his on-site help but he did diagnose the problem and was happy also to chat through my thoughts about an upcoming solar/battery install I'm planning. Great bloke.... if only he was nearer!

Diagnostics

6-step panel-level diagnosis

Work through these steps to identify why your Enphase panel has stopped reporting in Enlighten. Each step eliminates a different possible cause — from monitoring issues through to hardware failure.

1

Check Enlighten panel map for the affected microinverter

Log into Enphase Enlighten and open the array layout view. Identify which panel is showing as grey or not reporting. Click on the affected panel to see the microinverter serial number and the last reporting timestamp.

If the microinverter reported within the last 24 hours, the issue may be intermittent — a PLC communication glitch or a brief power interruption. If it has been offline for several days, the fault is likely persistent.

Also check whether surrounding panels are reporting normally. A single grey panel points to that specific microinverter. A cluster of grey panels on the same roof section suggests a branch circuit or wiring issue rather than individual microinverter failure.

2

Verify the Envoy gateway is online and communicating

Check whether the Envoy (IQ Gateway) itself is online in Enlighten. If the Envoy shows as offline, no microinverters will report — this is a connectivity issue, not a panel fault. The Envoy status should show a solid green network LED.

If the Envoy is online but specific panels are not reporting, the Envoy is receiving data from some microinverters but not others. This narrows the fault to the specific microinverter, its AC wiring, or the powerline communication path between that microinverter and the Envoy.

3

Check the AC branch circuit breaker

Enphase microinverters connect to the mains via AC branch circuits. Each branch typically serves a group of microinverters and has its own breaker in the consumer unit or combiner box. If that breaker has tripped, every microinverter on the branch will stop reporting and stop producing.

Check your consumer unit for any tripped breakers on the solar circuits. Reset the breaker if tripped. If it trips again immediately, there is a wiring fault on that branch — do not keep resetting it. Call an electrician. A single tripped breaker causing multiple panels to disappear simultaneously is one of the most common causes of Enphase "failures" that are not actually microinverter faults.

4

Assess powerline communication signal quality

Enphase microinverters communicate with the Envoy using powerline communication (PLC) — data signals sent over the AC wiring. If the PLC signal is weak or blocked, the Envoy cannot read the microinverter even though it may still be generating power.

Common PLC interference sources include arc fault circuit interrupters (AFCIs), certain LED drivers, battery chargers on the same circuit, or long cable runs between the microinverter and the Envoy.

The Envoy diagnostic page — accessible via envoy.local on your home network — shows PLC signal quality for each microinverter. Low signal strength on the affected unit while neighbouring microinverters show strong signals suggests a wiring issue on that specific run.

5

Identify whether the microinverter has failed

If the Envoy is online, the branch circuit breaker is closed, and PLC signal is adequate for surrounding microinverters, the non-reporting unit has likely failed. Enphase microinverters are sealed electronic units with no user-serviceable parts.

A failed IQ7 or IQ8 microinverter will show no LED activity and will not respond to the Envoy. The unit needs physical replacement — this requires roof access and a qualified electrician. Do not attempt to access the microinverter yourself.

Enphase IQ7 and IQ8 microinverters carry a 25-year warranty. If the unit has failed within the warranty period, it should be replaced at no cost. Your installer going out of business does not affect the warranty — it runs with the product.

6

Book a remote diagnostic if the cause is unclear

If you have checked the Enlighten panel map, confirmed the Envoy is online, verified the branch circuit, and the microinverter status is still unclear, a remote diagnostic can identify the root cause.

STS reviews your Enlighten production history, checks panel-level output trends before the failure, and cross-references Envoy communication logs to determine whether the issue is a failed microinverter, a PLC communication problem, or a wiring fault. We also prepare warranty claim evidence if the microinverter has failed.

Why Enphase panel-level monitoring changes the diagnostic process

With string inverter systems from GivEnergy, SolarEdge, or SolaX, a fault anywhere on the string affects the entire array. Diagnosis starts at the inverter and works outward. With Enphase microinverter systems, every panel operates independently — so when Enlighten shows a single grey panel, the fault is isolated to that specific microinverter from the start. The diagnostic question is not "where is the fault" but "what type of fault is it."

The three main categories are hardware failure (the microinverter has died), communication failure (the microinverter is generating but the Envoy cannot read it via PLC), and AC supply interruption (a tripped breaker or loose AC connector has cut power to the unit). Each requires a different resolution — replacement, PLC signal remediation, or electrical repair. Enlighten's production history often reveals which category the fault falls into before any physical inspection.

This panel-level visibility is one of the key reasons Enphase systems are well suited to remote diagnosis. We can often tell from Enlighten data alone whether a microinverter needs replacing, whether a PLC bridge is needed, or whether an electrician should check a specific AC junction. The homeowner avoids paying for an unnecessary site visit to discover something that was visible in the monitoring data all along.

Reference

Most common causes of a non-reporting Enphase panel

Microinverter failure
Single panel grey for days, surrounding panels normal

The microinverter has failed. No LED activity, no communication with Envoy. Requires physical replacement. Covered under 25-year warranty if within period.

Tripped branch breaker
Multiple panels on same roof section all go grey simultaneously

AC branch circuit breaker in consumer unit has tripped. Reset the breaker. If it trips again immediately, there is a wiring fault — call an electrician.

PLC signal lost
Panel intermittently reports, then drops out again

Powerline communication signal between microinverter and Envoy is too weak. Caused by electrical noise from other devices, long cable runs, or damaged wiring. A PLC bridge device may resolve the issue.

Loose AC connector
Panel stopped after storm or high wind event

The AC trunk cable connector at the microinverter has worked loose. More common on older installations where the Engage connector was not fully locked. Requires roof access to reseat — do not attempt this yourself.

Envoy offline
All panels show grey — entire system appears down

The Envoy gateway has lost its internet connection. The system is still generating — only the data stream to Enlighten is interrupted. See our monitoring offline guide.

FAQ

Enphase panel reporting — common questions

A grey panel means the Envoy has not received data from that microinverter recently. The three most common causes are a failed microinverter, a tripped AC branch circuit breaker cutting power to that group, or a powerline communication problem where the signal is blocked or too weak. Check Enlighten for the last reporting time — if it was recent, the issue may be intermittent. If the panel has been grey for days, the microinverter has likely failed or lost its AC connection.
No — each Enphase microinverter operates independently. If one fails, only that single panel stops producing. The rest continue generating normally. This is a fundamental advantage of microinverter architecture over string systems, where a single fault can stop all panels. However, if a branch circuit breaker has tripped, all microinverters on that branch will stop — this looks like multiple panels failing at once.
Enphase IQ7 and IQ8 series microinverters carry a 25-year limited warranty from installation date. Older IQ6 and M-series units carry a 25-year warranty as well. You need the microinverter serial number (visible in Enlighten) and the installation date. If your installer has gone out of business, the warranty still applies — it runs with the product, not the installer. STS can prepare the diagnostic evidence needed to support a warranty claim.
The Envoy has four indicator LEDs. The network LED should be solid green when connected to the internet. The AP mode LED flashes when the Envoy is broadcasting its setup WiFi network. The power production LED is solid green when microinverters are producing. The communication LED shows solid green when the Envoy has contacted all detected microinverters. If the communication LED is amber or flashing, the Envoy has lost contact with one or more units.
If several panels stop simultaneously, the most likely cause is a tripped AC branch circuit breaker. Enphase microinverters are wired in groups on branch circuits — if the breaker trips, every microinverter on it loses power and stops reporting. Check your consumer unit for tripped solar circuit breakers. Other causes include the Envoy going offline (all panels disappear) or a PLC fault affecting a specific wiring run.
