Growatt setup & how-to guides
STS engineers explain this setup procedure for Growatt systems step by step. Click any topic below for the full guide, or book a free remote diagnostic and we'll tell you what the fix is. The WiFi is the exception: it's never remote work. If the WiFi still won't connect after the guide, we can set it up on site, from £195.

- No fix, no fee

Great experience with STS great communication from Ron, very helpful and knowledgable. Installed me a second Givenergy battery to help take the strain off my original 9.5 that needs refurb due to a weak cell. They secured me an 8.2 arranged install. Levi arrived the whole install was done within 1.5 hours - great tidy job. Worked with me to alter my setup to allow easy removal of my 9.5 when i can get it away for refurb - very happy with their service and its reassuring to know there is a company out there that can help look after my givenergy system

As a Givenergy customer I have been forced to get familiar with my system since it developed battery failure. I managed to find someone to repair the battery and managed to do the physical install and connection. I reached out to Ron at Solar Tech Support and with the help of whatsapp and many screenshots of the system, cloud and App Ron managed to get me through getting it all up and running. Big thanks to Ron.👏👏

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.

I contacted Solar Tech Support because I had a problem with my legacy GiveEnergy installation. within 24 hours they had diagnosed the problem and offered advice on resolution. Because they were unable to fix the problem there was no charge! This despite numerous time consuming emails. I am currently trying to engage with the original installer but if that is unsuccessful I will go back to Solar Tech Support and ask them to repair the system with a retrofit. Very knowledgeable and responsive. I highly recommend them.

Solar Tech Support answered my initial enquiry swiftly. They provided remote support to establish what the issue was, and through their experience and network, managed to get my clients system back online. Once the system was online, STS managed to diagnose the main issue to get the ac coupled inverter and battery back online, a battery repair was required. A site visit was organise and within a few days, the system was tested and back up and running. This has saved my client, and probably myself huge costs and inconvenience now the system is back online and working correctly. Would highly recommend.

Setting up Growatt monitoring — what to get right
Growatt monitoring runs through two interfaces that share one login: the ShinePhone app and the ShineServer web portal at server.growatt.com. The setup itself is straightforward — register an account, create a Plant for your property, then add your inverter using its serial number — but two things trip people up. First, always register with an email address you own and control, not your installer's; an account tied to an email you can't access is the single most common reason homeowners lose monitoring later. Second, add the device using the inverter serial from the label (a 10-character code), not the WiFi datalogger's own serial — get those two mixed up and the device can show as registered but report no data.
The job that brings most people here, though, is the dreaded "device already registered" message. Growatt systems installed before about 2022 were almost always registered under the installer's ShineServer account, so when you buy a house with solar or your installer goes bust, you inherit a system you can't see. You can't override it from your end. If the installer is still trading they can reassign the Plant to you inside ShineServer, often same day with no paperwork; if they're gone, it's a formal orphaned-account transfer through Growatt UK at service@growatt.com — serial number, address and proof of ownership, typically 3 to 7 working days. Our ShinePhone setup and account transfer guide walks through both routes step by step.
As independent engineers we'll get you set up properly or prepare a transfer request that lands right first time. If the datalogger won't connect to your WiFi, we can set it up on site, from £195. If the signal doesn't reach, a WiFi extender is an extra £75, and we carry them with us. If it's the account side, such as a device added under the wrong serial, the remote diagnostic is free and you only pay £125 if we fix it remotely. Help setting up the ShinePhone account and Plant is a remote setup session at a fixed £145, and other on-site work, where it's ever needed, starts from £295.

Growatt ShinePhone setup — common questions
It means the inverter serial is already linked to another ShineServer account, usually your installer's or a previous homeowner's, and you can't force a fresh registration over the top of it. There are two routes. If the original installer is still trading, ask them to reassign the Plant to you inside ShineServer — that's the quickest fix, often same day with no documentation. If they've gone bust or are unreachable, it's an orphaned-account transfer: create your own ShinePhone account first, then email Growatt UK at service@growatt.com with your inverter serial number, the property address, proof of ownership (a completion statement, Land Registry document or solicitor letter) and your account email so they know where to move the device. Growatt typically processes these in 3 to 7 working days. We'll prepare the whole request so it's right first time, and we can't speed Growatt's side up but we can make sure it isn't bounced back for missing information.
Use the inverter serial number, not the datalogger's. It's printed on a white or silver label on the side or bottom of the inverter — look for the field marked S/N or Serial No. — and on most Growatt models it's a 10-character code, letters followed by numbers. It should also appear on the commissioning certificate or system spec sheet in any handover pack left by the installer. The WiFi datalogger has its own separate serial on a different sticker; if you accidentally register that one, the device can look registered but show no live data. If you enter the wrong one, remove the device from your Plant and re-add it using the inverter serial taken straight from the label.
After adding the device, allow 5 to 10 minutes for the first data to appear, as the datalogger reports at intervals rather than continuously. If it's still blank, the device is registered correctly but the WiFi datalogger isn't transmitting, so it's a connectivity issue, not an account problem; the system usually keeps running, so check the inverter's own screen. The usual causes are the datalogger not being on your home WiFi (it needs your 2.4GHz network, not the inverter's own hotspot), or a router or WiFi password change since installation that's left it disconnected and needing reconfiguration. If it still won't connect, we set it up on site, from £195: we connect it to your WiFi, set up your router, including a separate 2.4 GHz network if it needs one, and check it's reporting.
