There are two common reasons you need this guide — the setup process is different for each.

Ron very quickly diagnosed what was wrong with my GivEnergy system. Unfortunately the kit has died after only 3.5 years of use-which is quite sad and timing couldn’t be worse with GivEnergy gone bust. Ron gave me advise on how to handle this with my installer. I’m hoping they’ll be forthcoming, but if they aren’t i now have a good idea how to deal with that. Thanks a lot Ron!
My Givenergy system went offline, so I lost control of it. Ron from STS and Craig from Norfolk Solar were most helpful in diagnosing the problem by phone. Full marks for their patience and ability.
What a fantastic service. Had my fault diagnosed within minutes and actually managed to resolve the issue remotely within a few minutes more. This guy is like a “Solar Batman” helping consumers fix their problems using his extensive industry knowledge and expertise. Outstanding service. Thank you so much.
I’ve used Ron a couple of times regarding issues with my Givenergy inverter and batteries after Givenergy went bust. My system stopped working properly so it was a stressful time but Ron resolved the issues and got my system working properly again. He’s really helpful and knowledgeable and I wouldn’t hesitate to recommend him and to use him again if the need arose.
A really big thank you to Ron and his team, he has vast amounts of knowledge and got my system back up and running, also good to get on with. I was absolutely lost as to know what to do, no help from installer and somehow came across Ron and am I glad I did. I would definitely definitely recommend him to anyone who has faults with there solar system, any make I would say. Thanks again Ron a pleasure meeting you.
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. 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.
You need the inverter serial number to add your system to ShinePhone. Without it, you cannot register the device to your account. Find it before you start — it will save you having to go back to the inverter mid-setup.
The serial number is printed on a white or silver label on the side or bottom panel of the inverter. On most Growatt models it is a 10-character code — letters followed by numbers. Look for the field labelled S/N or Serial No.
If you received a handover pack from your installer or the previous homeowner, the serial number should be on the system specification sheet or commissioning certificate. Check any paperwork left in the property.
If the system is already showing data in ShinePhone under another account, the serial number may be visible in the device settings. Tap the plant, then the device, and look for the device information or details screen. This also confirms the exact format to use when contacting Growatt for a transfer.
NExxxxxxxxx or similar alphanumeric codes. If you have a WiFi datalogger (a small plug-in device attached to the inverter's RS485 port or USB slot), that also has its own serial number — make sure you use the inverter serial, not the datalogger serial, when registering in ShinePhone.
Follow these steps if the system has never been registered in ShinePhone, or if you're setting up your own account independently of any previous installer account. If ShinePhone tells you the device is already registered to another account, skip to the account transfer section.
Search for ShinePhone on the Apple App Store (iOS) or Google Play Store (Android). The official app is published by Growatt New Energy Technology Co. Ltd. Download and install it — the app is free. The app connects to the ShineServer cloud platform at server.growatt.com.
Open ShinePhone and tap Register to create a new account. Enter your email address and set a password. You can also register directly at server.growatt.com in a web browser — both use the same account. Use an email address you own and will always have access to, not a shared or temporary address.
Once logged in, tap the + icon and select Add Plant. Enter your installation details — address, installation date, and system capacity if known. The Plant is the container for your inverter(s) and battery. Give it a name you'll recognise, such as your house name or address.
Inside the Plant, tap Add Device and enter your inverter serial number exactly as it appears on the label — matching case. ShinePhone will search for the device on the Growatt network. If the serial is accepted, the inverter will be linked to your plant.
For live data to appear in ShinePhone, the Growatt WiFi datalogger (the small device attached to your inverter's communications port) must be connected to your home WiFi. If data doesn't appear within 5–10 minutes of adding the device, the datalogger may not be online. See WiFi not connecting for step-by-step help.
Most Growatt systems installed before 2022 were registered under the installer's ShineServer account, not the homeowner's. When you buy a property with solar already installed — or your installer has gone out of business — you inherit a system you can't access. This is called an orphaned account, and it requires a formal transfer request to Growatt.
If the installer is still trading and accessible, the simplest route is to ask them to either remove the system from their account (so you can add it fresh) or transfer the plant to a new account in your name via ShineServer.
If the installer has gone bust, is unresponsive, or the account was set up under a previous homeowner's details, you need to go directly to Growatt UK to request a forced transfer. This requires proof of ownership.
If path B applies to you, here is exactly what to do and what to include in your email to Growatt UK.
Before contacting Growatt, set up your own account at server.growatt.com or via the ShinePhone app. When Growatt processes the transfer, they will move the device registration into your account — so you need the account to exist and be ready. Note down your registered email address.
Before sending your email, collect the following. Missing information will delay the transfer.
Send a clear email to service@growatt.com — this is Growatt Technologies UK Ltd, the UK distributor responsible for handling account transfers and warranty support. Explain that you are the new property owner, provide all the information listed above, and attach your proof of ownership document. Be concise and factual — include all required information in the first email to avoid back-and-forth.
Growatt UK typically processes orphaned account transfers within 3–7 working days of receiving all required documentation. If you haven't heard back after 7 working days, send a polite follow-up referencing your original email date and serial number. Once transferred, you'll receive confirmation and the system will appear in your ShinePhone account.
If you bought a property with solar and are dealing with multiple issues at once — missing documentation, an absent installer, and no monitoring access — our bought a house with solar guide covers everything in sequence. For installer-specific account problems, see the monitoring account transfer guide for a full walkthrough across all brands.
Growatt's monitoring has two interfaces that use the same login. Understanding the difference prevents confusion when you're looking for specific settings or data.
The ShinePhone app is the primary day-to-day monitoring tool for most homeowners. It shows live generation, battery state of charge, grid import and export, and home consumption in a visual flow diagram. Historical data is accessible by day, week, and month.
ShineServer at server.growatt.com is the browser-based portal. It uses the same login as ShinePhone and shows the same monitoring data, but also provides access to data exports, inverter parameter settings, and more detailed device management tools — including account and plant management.
Same account, both platforms: You do not need separate accounts for ShinePhone and ShineServer. Create one account and use the same email and password to log in to both. Settings and data sync automatically — there is no advantage to using one over the other for monitoring, only for configuration and export tasks where ShineServer provides more options.
If you've completed setup but ShinePhone shows zero figures, no live flow, or "--" across the dashboard, the inverter has been registered correctly in your account but the datalogger is not transmitting data to Growatt's servers. This is a WiFi or connectivity issue — not an account problem.
The datalogger must be connected to your home WiFi — not the inverter's own hotspot. Check the datalogger's indicator light: a steady light usually indicates a live connection; a flashing or orange light typically indicates it is searching for a network or has lost connection. Follow the WiFi not connecting guide to reconnect it.
If your home WiFi password has been changed since the system was installed — including after a new router — the datalogger will have lost its connection and needs to be reconfigured. This requires logging into the datalogger's own configuration interface, usually accessed via its temporary hotspot. See the WiFi reconnection guide for the full process.
After first connecting the datalogger, allow 5–10 minutes for the first data to appear in ShinePhone. The datalogger sends updates at intervals rather than continuously. If data still hasn't appeared after 20 minutes and the datalogger appears online, try force-closing and reopening the ShinePhone app before assuming there is a problem.
If you entered the datalogger serial number rather than the inverter serial number, the device may appear registered but show no data — or it may show an error. Remove the device from your plant and re-add it using the inverter serial number taken directly from the label. The datalogger's serial is typically on a separate sticker or the packaging.
If ShinePhone is consistently showing no data and you've confirmed the datalogger is connected, the issue may be with the datalogger itself or an inverter communication fault. See the full monitoring offline guide for a complete diagnostic, or book a remote diagnostic for hands-on help.
Whether the datalogger won't connect, the account transfer isn't moving, or you've set everything up and still see no data — we can diagnose the issue remotely and walk you through the fix. Engineer-to-homeowner, plain English. Setup support from £95.
