Brand identification guide · 10+ UK brands covered

Find out what solar inverter you have

Q: The label is faded or unreadable — what can I do?

Try these alternatives in order: (1) check the display screen — many units show the model number on startup; (2) look for an installer sticker near the inverter or on the consumer unit door with the system specification; (3) enter any partial text from the label into a search engine; (4) check the MCS certificate from your property documents. If none of these work, a remote diagnostic can identify the brand from monitoring data.

Q: I've found the brand — what do I do next?

The next step for most new homeowners is establishing monitoring access and registering the system in your name. Each manufacturer has a different process and portal. Use the brand guide links on this page for your specific manufacturer, or see our guide to claiming monitoring access as a new homeowner for the full step-by-step process.

The fastest way is to look at the label on the front or side of the inverter unit — the brand name is printed clearly. If the label is damaged or missing, this guide covers three alternative identification routes and a visual reference for every major UK brand.

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)

Tony Deacon · May 2026 Trustpilot

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

Phill · May 2026 Trustpilot

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.

Christopher · Apr 2026 Trustpilot

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!

Three ways to find your inverter brand

Try them in this order. The label is by far the quickest — only use the alternatives if the label is damaged, missing, or the unit is inaccessible.

🏷️

1. Read the inverter label

The brand name, model number, and serial number are on a sticker on the front, side, or back of the unit. The quickest route — takes 30 seconds if the unit is accessible.

How to read it →

📱

2. Check the monitoring app

If you still have access to the previous owner's monitoring portal, the brand, model, and serial number are listed in the device or system settings section.

Only works while the previous owner's login is accessible.

📄

3. Check the MCS certificate

The MCS certificate issued at installation legally requires the inverter manufacturer and model to be listed. It should be in your property documents pack from completion.

How to find MCS documents →

ℹ️

Once you have the brand name, jump to the brand visual reference below to confirm it and get a direct link to the right guide for your system.

Where to find the inverter

Every grid-connected solar system has an inverter — it is always mounted inside on an internal wall. These are the most common locations, in order of how often we see them in UK properties.

Garage (most common)

The most common location for hybrid inverters installed from 2019 onwards. Usually on the back or side wall, near the consumer unit. If there is a battery, it will be on the floor beside it.

Utility room or boiler cupboard

Second most common. Typically mounted beside or near the boiler, with cables running through the ceiling toward the roof space.

Loft or roof space

More common in older solar-only systems (pre-2018). The inverter will be near the point where the panel cables enter the roof. Bring a torch.

Under the stairs

Common in terraced and semi-detached houses without a separate garage or utility room. Check under-stair cupboards for a wall-mounted box with cables.

Airing cupboard

Occasionally installed near the hot water cylinder. Not common, but seen in properties without a garage or utility room with suitable wall space.

Can't find a wall unit? Check for Enphase

Enphase systems use microinverters — small units mounted under each panel on the roof frame or loft rails, not one central box. If there is no wall unit, you likely have Enphase.

External enclosure (rare)

A small number of older or commercial-grade installations have the inverter in a weatherproof external enclosure on an outside wall. If you cannot find it internally, check outside near the main cable entry point.

Still can't locate it? Follow the solar circuit cable at the consumer unit — it leads directly to the inverter.

Reading the label

The label is the definitive source for your inverter's identity. Here's exactly what you're looking for.

Find the label on the unit

Check the front, right side, and back of the inverter. Most units have a sticker on the front or side. On some older units (particularly Growatt and SMA) the detailed spec label is on the back — if the unit sits close to the wall, look for a fold-out or secondary label on the side panel. Some GivEnergy units also have a QR code that links directly to the product page — scanning it will confirm the brand and model immediately.

Identify the brand name

The manufacturer name is usually the most prominent text on the label — GivEnergy, Sunsynk, SolarEdge, Growatt, Solis, Enphase, Fronius, SMA, Huawei, Fox ESS. On SolarEdge units the label will say "SolarEdge Technologies". On Solis units it may also show "Ginlong" — the parent company. If the brand name isn't immediately obvious, look at the logo on the front face of the unit.

Photograph the model number and serial number

The model number identifies the product type — for example GE-5.0 (GivEnergy 5kW), SPH5000TL BL-UP (Growatt 5kW hybrid), or SE6000H (SolarEdge 6kW). The serial number is unique to your specific unit — a string of letters and numbers, usually 10–20 characters.

Photograph the full label clearly. Both are required for warranty claims, monitoring access transfer, and any future manufacturer contact. Store them in your phone notes or a home folder.

Check for a separate battery unit

If the previous owners had a battery system, look for a second box — often mounted alongside or below the inverter on the floor or wall. Common battery brands include GivEnergy (Giv-Bat), Sunsynk, Pylontech, BYD, and Sungrow. The battery may be from a different manufacturer than the inverter — this is normal.

Photograph the battery label separately. The battery and inverter are registered and sometimes monitored independently — you will need both serial numbers if you contact either manufacturer for warranty or support.

SolarEdge brand guide →

Growatt Both solar-only and hybrid models common in UK

Grey or white unit with "GROWATT" printed prominently. Solar-only models: MOD and MIN series. Hybrid models: SPH and MIN TL-X series. The SPH series (Growatt hybrid) is distinct from the MOD/MIN solar-only range — SPH units are larger and have battery connections. Monitoring via ShinePhone app or ShineServer portal (shine.growatt.com).

Growatt brand guide →

Solis Also branded Ginlong — parent company name

White unit with "Solis" or "Ginlong Solis" on the label. Ginlong is the parent company — Solis is the inverter brand. Common in solar-only installations from 2015–2022, with hybrid models (S5, S6 series) in more recent installs. Monitoring via SolisCloud portal (home.soliscloud.com).

Solis brand guide →

Enphase Microinverter system — no central wall-mounted unit

Enphase does not use a central wall-mounted inverter. Instead, individual microinverters (IQ7, IQ8 series — small rectangular units roughly the size of a hardback book) are mounted under each solar panel on the roof rail or loft frame. If you cannot find a wall-mounted unit but have solar panels, check the loft for small Enphase-branded boxes on the panel mounting rails. Monitoring via Enlighten portal (enlighten.enphaseenergy.com).

Enphase brand guide →

Fronius Austrian brand — common in commercial and older domestic

White unit, typically with an orange logo or orange accent on the casing. Austrian-manufactured. Common domestic models: Fronius Primo (solar-only, single-phase), Fronius Symo (three-phase), Fronius GEN24 Plus (hybrid, more recent). Label reads "Fronius". Monitoring via Fronius Solar.web portal.

If the label is damaged or unreadable

Four alternatives to try, in order of reliability.

▸

Check the display screen. Most inverters show the model number or brand name on the display during startup, or within the settings menu. Press any button to wake the screen. Some units cycle through brand name → generation figure → status information on the idle display.

▸

Look for an installer sticker. Most solar installers attach a sticker near the inverter or on the inside of the consumer unit door, listing their contact details and the system specification — usually including inverter brand and model. Check the wall immediately around the inverter and the consumer unit door.

▸

Search any partial text online. Even a partial model string — for example "SPH5000", "GE-5", or "SE6000H" — typed into a search engine will return results that identify the manufacturer. Use the exact string from the label, including hyphens and numbers.

▸

Check the MCS certificate. The MCS certificate from your property documents pack lists the inverter manufacturer and model as a legal requirement for any UK system installed since 2010. If it is missing, your solicitor may hold a copy — or see our guide to finding your MCS documentation.

▸

Check the monitoring app if still active. If the previous owner's monitoring app or portal is still showing data, the device settings section will usually display the inverter make, model, and serial number. This only works while the previous owner's login is accessible — once they close the account or you transfer it, this route closes.

Once you've identified your inverter brand

The next step for most new homeowners is getting monitoring access and registering the system in your name. Each brand uses a different process and portal.

FAQ

Frequently asked questions

What does a solar inverter look like?

A solar inverter is a rectangular box mounted on an internal wall — typically 30–50cm wide and 40–60cm tall. Most UK models are white or cream. They have at least one black DC cable running toward the roof (from the solar panels) and cables going into the consumer unit. Most have a small LED display or indicator lights. Hybrid inverters that also manage battery storage are generally larger than solar-only string inverters.

Where is the solar inverter in my house?

Almost always on an internal wall inside the property. The most common locations are: garage (by far the most frequent), utility room, airing cupboard, loft, or under the stairs. If you cannot find it, follow the cables from the solar circuit in your consumer unit — they lead directly to the inverter. It is very rarely located outside.

I can't find an inverter anywhere — do I definitely have one?

Yes — all grid-connected solar systems require an inverter. The exception is Enphase, which uses microinverters: small individual units mounted under each solar panel on the roof rail or loft frame, rather than one central wall-mounted box. If you cannot find a wall unit but you have solar panels, check the loft for small rectangular Enphase-branded units on the panel mounting frame. That is an Enphase microinverter system.

How do I tell if I have a hybrid inverter (with battery) or solar-only?

A hybrid inverter has battery connection ports — you will see DC cables going to a battery unit as well as the solar DC cables from the roof. A solar-only string inverter has only the solar DC input and AC output connections, with no battery port. If there is a second box connected to the main unit, it is a hybrid system. The label may also say 'hybrid', 'storage', or 'HV battery' to confirm.

The label is faded or unreadable — what can I do?

Try these in order: (1) check the display screen — many units show the model number on startup; (2) look for an installer sticker near the inverter or on the consumer unit door; (3) search any partial model text online — even a few characters are usually enough to identify the brand; (4) check the MCS certificate from your property documents. If none of these work, a remote diagnostic can identify the brand from monitoring data — contact us and we can usually confirm it same day.

I've found the brand — what do I do next?

The next step is almost always establishing monitoring access and registering the system in your name. Each manufacturer has a different process and portal. Use the brand guide links in the "Once you've identified your inverter" section above for your specific brand, or see our guide to claiming monitoring access as a new homeowner for the full step-by-step process including required documents.

System ID

Can't identify it — or need a written system report?

If the label is unreadable and none of the alternatives work, a remote diagnostic can identify the brand and model from monitoring data alone. If you need a written system condition report for insurance, a mortgage, or conveyancing, that is included in every inspection.
