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

Dennis Brown · May 2026 Trustpilot

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 Ron with a problem and he sorted it out quickly with no problems at all. Very knowledgeable on anything solar/ batteries. I would recommend him to anyone

I've spoken to Ron a couple of times with issues with my Givenergy installation. Such a friendly knowledge guy very highly recommended. Thank you very much for resolving my issues

michael fairhurst · May 2026 Trustpilot

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.

Mr Machin · May 2026 Trustpilot

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.

Hugh Speirs · Apr 2026 Trustpilot

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!

How to find your panel status code. Enphase panel status codes appear in the Enlighten Manager portal (enlighten.enphaseenergy.com) and the Enphase app. Click on any individual panel in the system map — the panel detail shows its current status code. A panel showing in yellow, red, or grey in the system map has a status code. Take a screenshot of the full system map and note which panels are affected.
Not producing status codes

Panel status codes when the microinverter is not generating power. Some are normal (night, low light), others indicate a fault.

Power too low Generating below minimum
The microinverter is reporting that the panel is generating less than expected. Check for shading, soiling, or a bird strike on the affected panel. If a single panel is affected while neighbours are producing normally, the panel itself or the microinverter may be faulty.
Sleeping (night / low light) Normal nighttime state
Expected status when irradiance is below the minimum threshold for generation. Not a fault. Clears automatically at dawn.
Gridless No grid connection
Microinverter has lost grid connection. Check AC isolator and consumer unit. If one microinverter shows this while others are producing, the affected unit may have a relay or internal fault.
Not communicating / Unknown ⚠ Offline
Microinverter is not sending data to the Envoy. Check the Envoy LED — three solid green LEDs indicate normal operation. A panel showing Unknown for more than 24 hours during daylight may have a power line communication fault or a hardware failure.
Communication / Envoy faults

Status codes related to communication between the Envoy gateway and microinverters, and to internet connectivity.

Envoy offline ⚠ No Envoy comms
The Envoy gateway has lost internet connection. Check Envoy ethernet cable or WiFi connection. A flashing amber broadband LED on the Envoy indicates connectivity loss. Power cycling the Envoy (unplug for 30 seconds) often restores connection.
Microinverter not discovered Device discovery failed
New microinverter not found by the Envoy. Ensure the microinverter has been installed on a powered panel, wait 20 minutes for discovery, then re-scan in Enlighten Manager.
PLC communication error Power line signal lost
Power line communication between microinverter and Envoy has failed. Check that the Enphase power line carrier module (if fitted) is plugged in at the distribution board. If no PLC module, the microinverter uses the AC wiring — check there are no arc fault breakers or AFCI breakers interrupting the signal.
Grid events

Grid voltage and frequency events that cause the microinverter to disconnect as a safety protection.

Grid frequency out of range Frequency protection trip
Grid frequency outside acceptable range (49.5–50.5 Hz). Transient events clear automatically. Recurring issues indicate a grid-side fault — contact DNO.
Grid voltage out of range Voltage protection trip
Grid voltage outside acceptable range (207–253V). Check AC connections. Contact DNO if recurring.
G98 / G99 trip Protection disconnect
Microinverter tripped on G98 or G99 protection. Check grid conditions — this is a safety protection function, not a fault.
Microinverter hardware faults

Status codes indicating hardware faults in the microinverter unit itself.

DC voltage too high Panel voltage high
Panel open-circuit voltage too high for microinverter input. Check panel Voc specification against IQ8 or IQ7 microinverter maximum input voltage.
Over temperature Microinverter overheating
Microinverter temperature too high. Check that the panel mounting has adequate clearance for airflow beneath. A microinverter on an inadequately ventilated flat roof can overheat in summer.
Microinverter fault ⚠ Hardware fault
General microinverter internal fault. Power cycle the affected string (AC isolator off, wait 2 minutes, back on). If the fault persists after 2 power cycles and the panel is producing zero, the microinverter unit may need replacement.
Enlighten / monitoring faults

Status codes related to the Enlighten monitoring portal and data reporting.

System not reporting Portal data gap
Enlighten has not received data from the system. Check Envoy LED status. If Envoy is online but Enlighten shows no data, there may be a cloud-side processing delay — common after firmware updates. Wait 24 hours before escalating.
Array count mismatch Inventory mismatch
Enlighten is expecting a different number of microinverters than are discovered. This occurs after adding panels or if a microinverter goes offline permanently. Re-scan from Enlighten Manager.

Enphase releases firmware updates that may introduce new status codes. If your code isn't listed, share the exact status from your Enlighten system map and we'll identify it.

FAQ

Enphase status code questions

Panel status codes appear in the Enlighten Manager portal at enlighten.enphaseenergy.com and in the Enphase app. Click on any panel in the system map to see its current status and code. Panels showing in yellow are warning status, red indicates a fault, and grey means the panel is not reporting. Take a screenshot of the full system map showing all panel statuses before contacting support — this is the most useful diagnostic information we can have.
A single panel showing as not communicating usually means that specific microinverter has lost power line communication with the Envoy gateway, or the microinverter itself has stopped responding. First, check whether the panel is shaded (shaded panels can drop to zero without a fault). If it is unshaded and neighbouring panels are producing normally, try a power cycle — turn the AC isolator off, wait 2 minutes, then back on. If the panel still shows unknown after a full day of generation, the microinverter unit may need replacement.
The Envoy goes offline when it loses its internet connection. Check the broadband LED on the Envoy — a solid green LED means internet is connected. A flashing amber LED means connectivity is lost. Check your router and ethernet cable (or WiFi signal if using wireless). Power cycling the Envoy by unplugging it for 30 seconds usually restores the connection. If the Envoy's broadband LED remains off, check that your router is functioning and that port 443 outbound is not blocked.
Yes, many Enphase microinverter faults can be initially assessed through the Enlighten monitoring platform. STS offers remote diagnostics from £75, and if an on-site visit is needed, our engineers are experienced with the full Enphase product range.
