Brilliant support to get my solar battery working again. I didn’t expect help on a Saturday but Ron answered the phone, listened and sent me the information I needed to get it going, answered questions etc. A brilliant service I’d happily recommend.
Ron was brilliant. He really tried to help. He spent hours trying to fix our GivEnergy AIO and ultimately it became apparent that it needed parts to fix the BMS management system. As there appears to be no replacement parts available on the market, he gave excellent advice on what options are now available to move forward. He is incredibly helpful and knowledgeable.
Called back within a day and gave good advice.
Ron was extremely helpful and tried his best to repair/reset our GivEnergy inverter remotely. In the event he was unsuccessful but he couldn’t have been more helpful. If you have problems with a GivEnergy system please contact him. Highly recommended
Big thanks to Ron. He was incredibly patient and helpful over the phone, taking the time to walk myself and the installer through every troubleshooting step. Through lots of testing he figured out the issue was definitely a hardware issue, which allows us to consider our next steps. Support fees are clear and they operate a “no fix no fee” policy. It is rare to find that kind of honesty combined with dedicated phone support nowadays. I highly recommend Ron, if you need help with your solar system don’t hesitate to give him a call.
A superb service from Ron who went beyond the normal service received from other Tech support companies. I live abroad and was badly let down when my givenergy system failed (and the company went bankrupt) and the local supplier ran away from the problem. Ron sorted the problem and even accessed specialist coding for the inverter that would not be available for suppliers. Ron also ran a full diagnostic to insure that all was in good working order afterwards. Without Rons support and patient assistance I doubt I would ever have got the system back up and running. Well done and thankyou and you have a customer for the future.

Every fault below has a proven diagnostic path. Click through for the specific page or book a diagnostic if you're unsure.
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 →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 →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 →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 →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 →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 →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 →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 →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.
We review Enlighten panel data, microinverter output history, and Envoy connectivity logs to identify the exact fault without a site visit.
Installer gone bust, Enlighten access lost, or monitoring never set up? We recover Envoy access and transfer Enlighten account ownership.
Full panel-level performance audit — compare actual vs expected output for every microinverter, identify degraded units, verify AC wiring integrity.

Seeing an error code on your Enphase system? Our fault code index explains what each code means, common causes, and safe next steps.
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.
STS supports all major inverter and battery brands — not just Enphase. If you have a mixed-brand system or are comparing options, visit the brand hub.
