Thank you for your diligence. On this occasion the battery was able to be saved but they have given a route to hopefully arrange a repair from the manufacturer.

Panel not showing in Enlighten?
One panel offline or the whole Envoy down — Enphase systems are diagnosable at panel level. We identify exact microinverter failures remotely.

Ron was really helpful. He remotely adjusted my battery settings on the same day I contacted him, and at a reasonable price. Great service.

After 7 months of not being able to access/control my system following a change of wi-fi provider, followed by the news that GivEnergy had ceased trading i was left high and dry. I was unable to get any help whatsoever from my installer, tried various electrical tradespeople etc but no-one knew how to help me. Changed the Dongle but then couldnt get this change recognised in the inverter. Found Solar Tech Support while researching yet again online. Ronald has been amazing. Responding very quickly to my emails and very knowledgeable on the system. Managed to give us the information we needed to get the Dongle up and running and created me another account which now works as it should. His help has been invaluable. Thank you so much. Reviews I saw from other people said Solar Tech Support are very good, but i would say they are Outstanding!! Thanks again for all your help- Mick & Sandra

Wow... a firmware update to my inverter sent the whole system into meltdown – the battery discharged, and the house seemed to be drawing power, and the solar, who knows where that was going? Aghhh... A short email exchange with Roland and Solar Tech Support sorted the problem... the firmware had reversed a setting (from when it was installed), and the CT clamp needed to be reversed. As soon as I had done that, the world returned to normal. Thanks, Roland; there is no way I would have come to that conclusion. Would I recommend them? You bet! Worth the fee? You bet, again!

Great service. Got our Givenergy battery back online remotely when others said it needed an onsite visit. Ron resolved the issue within about an hour of my email. Brilliant service.

Enphase Faults
Common Enphase problems we diagnose
Every fault below has a proven diagnostic path. Click through for the specific page or book a diagnostic if you're unsure.
Microinverter & Production
Panel issue
Panel not reporting in Enlighten
A panel showing as grey or N/A in Enlighten typically means the microinverter for that panel has stopped producing. It could be a failed unit, a loose AC connector, or the microinverter has tripped its own protection. Enlighten's panel-level view makes the exact location clear.
See diagnostic guide →Common
Whole system not producing
If all panels show as offline in Enlighten, the Envoy gateway has lost contact with the microinverters or the AC supply to the array has been interrupted. Check the Envoy indicator lights and verify the AC breaker for the solar circuit is closed.
See diagnostic guide →Hardware
Individual microinverter failure
Unlike string inverters, a failed Enphase microinverter affects only one panel. The Enlighten portal shows the affected panel clearly. We identify whether the unit needs replacement or if an AC wiring issue is the cause.
See diagnostic guide →Monitoring & Connectivity
Common
Enlighten / Envoy offline
The Enphase Enlighten portal shows no recent data. The Envoy (IQ Gateway) has lost its internet connection. The solar system continues generating normally — only the data stream to Enlighten is interrupted. Usually caused by router change, WiFi password update, or Envoy hardware fault.
See diagnostic guide →Setup
Envoy WiFi reconfiguration
After a router upgrade or ISP change, the Envoy needs reconnecting to the new network. This is done via the Installer Toolkit app or the local Envoy web interface at envoy.local. We guide you through the reconnection process remotely.
See setup guide →Performance
System underperforming
Enphase Enlighten provides panel-by-panel performance history. If overall generation is below expected, we compare individual panel outputs to identify which microinverter or microinverters are performing at reduced capacity.
See diagnostic guide →Warranty & Installation
Warranty
Microinverter warranty claim
Enphase IQ7 and IQ8 microinverters carry a 25-year warranty. If a unit has failed and is within warranty, we prepare the diagnostic evidence needed to support a claim with Enphase Energy Ltd. Your installer going bust does not affect the warranty.
See diagnostic guide →EPS
No backup during power cut
Enphase IQ8 series microinverters support 'Sunlight Backup' mode — the ability to power essential loads directly from solar panels during a grid outage without a battery. This requires specific wiring and configuration that many installers haven't completed correctly.
See diagnostic guide →
Panel Status
Enphase Enlighten panel status guide
Enphase systems report status at the panel level rather than showing single error codes. Common Enlighten statuses: grey panel (microinverter not communicating), yellow triangle (reduced production), red (microinverter error state). Share your Enlighten screenshot when you book — we identify the exact microinverter fault from the panel-level data.
Panel statuses
·Grey — microinverter not communicating
·Yellow triangle — reduced output
·Red — error state
·Production gaps — historic data missing

About Enphase systems — what you need to know
Enphase Energy makes microinverter systems — fundamentally different from the string inverters used by GivEnergy, Growatt, SolarEdge and others. Instead of one central inverter handling power from all panels, each Enphase panel has its own IQ microinverter (currently IQ7 or IQ8 series) mounted directly behind it. The microinverter converts DC power to AC at panel level. This means each panel operates independently — shading on one panel doesn't affect the others, and a single microinverter failure doesn't stop the rest of the array.
Monitoring is provided by Enphase Enlighten — a cloud-based portal that shows production at the individual panel level. The local Envoy (or IQ Gateway) collects data from all microinverters via powerline communication and pushes it to Enlighten. The most common searches we handle for Enphase: panel not showing in Enlighten, Enphase Envoy offline, Enphase microinverter failed, and Enphase installer gone bust. STS provides independent Enphase support across the UK — not affiliated with Enphase Energy Inc.

In Enphase systems, each panel has its own microinverter. A panel that stops reporting in Enlighten usually means the microinverter for that panel has failed, lost AC power, or the Envoy gateway has lost its local network connection. Because each microinverter is independent, one failure does not affect the others — the rest of the system continues generating normally.
The Envoy gateway needs a stable internet connection (WiFi or ethernet) to push data to Enlighten. After a router change or password update, the Envoy needs reconfiguring through the Installer Toolkit app or the local Envoy web interface at envoy.local. The system continues generating even when Enlighten shows the Envoy as offline.
No. Enphase microinverter systems are designed so each panel operates independently. If one microinverter fails, only that panel stops generating — the rest continue normally. This is one of the key architectural differences from string inverter systems, where a single fault can stop all generation.
Enphase IQ7 and IQ8 series microinverters carry a 25-year warranty as standard — significantly longer than the 5–10 year warranties typical of string inverters. The warranty runs from installation date. If your installer has gone out of business, the warranty is still valid and runs with the product.
