How to contact Growatt support in the UK

My inverter has stopped reporting, so who do I call? Is my Growatt warranty still valid, and how do I register it? Can I fix the ShinePhone app myself?

Growatt makes solar inverters and batteries, and here you can find the UK phone number and email for support, the steps to register a warranty, fixes for ShinePhone and ShineServer problems, and what to do about your data.

Short answer

Growatt support for UK householders runs almost entirely by email and through the installer who supplied the system. The maker's service address is service@growatt.com, used for both warranty matters and security vulnerability reports, and product or compatibility questions go to info@growatt.tech1. Growatt states plainly that it does not offer an installation service, so the firm that fitted the equipment is the first point of contact for anything physical3.

The company describes itself as one of the world's largest manufacturers of PV inverters and energy storage systems, present in the PV market for well over a decade, with an extensive service network in Europe1. It reports more than 1.7 million end users connected to its cloud platform, systems installed in more than 180 countries, and 43 or more representative offices worldwide, figures dated 15 September 20252.

For a household, the practical picture is this: the hardware and the monitoring platform are Growatt's, the installation and the physical repair route are the installer's, and the warranty clock starts on the installation certificate rather than the day the box arrived3.

Who Growatt is: scale, ownership and company status

Growatt's own product pages describe it consistently as one of the world's largest manufacturers of PV inverters and energy storage systems, present in the PV market for well over a decade, supplying residential, commercial and industrial installations in dozens of countries1. The same description appears across its battery, hybrid inverter and single-phase inverter pages, which is the maker's positioning rather than an independent assessment6.

The scale figures are the maker's own and dated 15 September 2025: more than 1.7 million end users connected to the cloud platform, more than 180 countries with systems installed, and 43 or more representative offices worldwide2. Those numbers describe a company with a substantial installed base and a monitoring platform that many households depend on for day-to-day visibility of their system.

What the material does not provide is a UK company registration, a UK office address or a UK telephone number. Growatt's European distribution is handled through growatt.tech, which describes itself as a Growatt European Distributor2. That matters for a household's energy independence: the inverter and battery sit on your property and keep working during a grid outage if the system is configured for backup, but the monitoring, the firmware and the warranty all depend on a manufacturer and a distributor outside the UK.

There is no indication in the material that Growatt has failed or is in administration, and no recall or safety notice is recorded against it. The company status is that of a going concern with a European distribution arm. For a fuller picture of how manufacturer scale and ownership affect UK buyers, see who owns which energy brand and the manufacturers pillar.

UK availability: buying through the growatt.tech shop

Growatt equipment is sold in the UK through the growatt.tech shop, which the maker states carries Growatt equipment with full documentation and a European service warranty1. Trade prices require a login, so the shop serves both householders and installers, with compatibility confirmed before purchase7.

Accessories follow the same route. The APX 5.0P-B1 connection cable, which links two sets of batteries, is listed as a genuine accessory with a European service warranty8. The SYN-100-XH-30 backup box for the MID-XH range is described in the same terms, with compatibility confirmed before purchase through info@growatt.tech9. The BDC 95045-A1 base is sold through the shop with the same compatibility check7.

Buying direct does not remove the installer from the picture. Growatt does not offer an installation service, so the equipment still needs fitting by a competent firm, and the warranty period runs from the installation certificate3. For the wider question of when direct purchase makes sense, see buying direct from a manufacturer.

Support routes for UK householders

The support routes are narrow and email-based. Growatt's warranty documentation gives service@growatt.com as the service email address3, and the same address appears in its vulnerability handling guidelines for reporting security issues4. Product and compatibility questions go to info@growatt.tech, which is the address given on the SPF 6000ES off-grid inverter page5.

Growatt does not offer an installation service3. That single sentence shapes the whole support chain: the installer who fitted the system is responsible for physical inspection, safe isolation and replacement, while Growatt handles the equipment, the warranty claim and the monitoring platform. A household that bought through a distributor has two parties to deal with, and the distributor's role is UK price and availability rather than technical support.

When raising a fault, the information Growatt needs is the model, the serial number and the fault code. Growatt's product pages carry a manufacturer code for each model, such as 99475 for the WIT hybrid inverter, which identifies the model rather than the individual unit10. The serial number itself is on the rating label and in the monitoring app.

For the general mechanics of keeping a warranty valid, see registering a warranty and keeping it valid and manufacturer technical support and spare parts.

Monitoring: the ShinePhone and ShineServer ecosystem

Growatt's monitoring runs on the ShinePhone app and the ShineServer portal, described by the maker as one app for all Growatt products and as a system monitoring app for users6. The ecosystem extends across the range: the SPF 6000ES off-grid inverter uses ShinePhone and ShineServer monitoring5, and the SYN-100-XH-30 backup box, the TPM-CT-E-EU three-phase meter, the SYN 50-XH-10 and the BDC 95045-A1 base all become part of a system monitored in the ShinePhone app and the ShineServer portal once connected9.

Access is by email address and password. Growatt's own support article on monitoring access for end users and installers describes entering login information such as an email address and password and pressing sign in12. The residential storage system adds 24-hour self-consumption monitoring and remote firmware upgrade for inverter and battery, which is how fixes reach a system without a site visit13.

The smart meter connects directly to the inverter, which is how the monitoring platform sees household consumption alongside generation14. That direct connection is what makes the self-consumption figures meaningful rather than estimated.

"Once connected, the device becomes part of a system monitored in the ShinePhone app and the ShineServer portal."

The independence question here is real. The inverter and battery keep working without the cloud, but the app, the history and the remote firmware updates do not. A household that wants visibility of its own generation is relying on a manufacturer's servers, an account and an internet connection. For the wider pattern, see firmware updates, app support and product lifespan.

Data security: what Growatt says and what to do

Growatt's published position on data security is limited to a reporting route rather than a policy statement. Its vulnerability handling guidelines ask that anyone discovering a security vulnerability inform the company by email at service@growatt.com4. That is the same address used for service and warranty matters, so a household reporting a monitoring concern and a household reporting a faulty inverter use the same channel.

The monitoring account itself is protected by an email address and password12. Growatt's residential storage documentation does not set out encryption, retention periods or data residency, and the material available does not describe them. That absence is worth stating plainly: a household connecting a Growatt system to the cloud is placing generation and consumption data on a manufacturer's platform without a published retention statement in the documentation reviewed here.

For comparison, other platforms in the UK market publish more. equiwatt states that data is stored on secure servers and that access to personal data is limited to only employees and third parties strictly necessary to provide the services15, and directs data rights enquiries, including erasure and portability, to support@equiwatt.com16. Those are different companies with different policies, but they show the level of detail a household can reasonably ask for.

Official UK guidance on metering data provides the legal backdrop: data provided is treated in accordance with the Data Protection Act 2018 and the UK General Data Protection Regulation17. That obligation applies to any organisation processing household energy data in the UK, Growatt included.

For how monitoring and app support affect the working life of a system, see firmware updates and product support life, and for the wider brand picture, Growatt inverters and home batteries.

Questions

Answers here, and more on their own pages.

How do I register my Growatt warranty in the UK?

Growatt's warranty terms set the standard period from the date of installation shown on the installation certificate, and no more than six months after the delivery date from Growatt. Keep the original purchasing invoice, installation documents or receipts, because these must be presented for a claim if required. Registration runs through the installer who supplied the system, and the paperwork is what proves the start date.

Does Growatt have an office in the UK?

Growatt states that it has 43 or more representative offices worldwide, but the material available does not identify a UK office address or a UK telephone number. Support is handled by email, principally service@growatt.com for service and warranty matters, and info@growatt.tech for product and compatibility questions. UK buyers also deal with the distributor that supplied the equipment.

Where do I find the serial number on my Growatt inverter?

The serial number is printed on the inverter's rating label, normally on the side or underside of the casing, and it is also recorded in the ShinePhone app once the device is connected. Growatt's own product pages carry a manufacturer code for each model, such as 99475 for the WIT 6kW-HU, which identifies the model rather than the individual unit. Quote both when raising a fault.

How do I contact Growatt support about a fault code?

Email service@growatt.com with the model, serial number, fault code and a photograph of the inverter display. Growatt's vulnerability reporting guidance uses the same address, so it handles both service and security matters. Product and compatibility questions go to info@growatt.tech. Growatt does not offer an installation service, so physical work on the system sits with the installer who fitted it.

What is the Growatt Protocol?

The material available does not describe a Growatt Protocol. Growatt's own documentation covers the ShinePhone app and ShineServer portal, the monitoring ecosystem that connects its inverters, batteries and meters, and the communications methods those devices use. Any claim about a specific Growatt protocol should be checked against the documentation supplied with the individual product rather than assumed.

How many people use the Growatt cloud platform?

Growatt states that more than 1.7 million end users are connected to its cloud platform, with systems installed in more than 180 countries and 43 or more representative offices worldwide. Those figures are the maker's own and are dated 15 September 2025. They describe the scale of the monitoring platform that ShinePhone and ShineServer run on.

Can I buy Growatt equipment directly online in the UK?

Growatt equipment is sold through the growatt.tech shop, which carries full documentation and a European service warranty, with trade prices requiring a login. Compatibility is confirmed before purchase, and questions go to info@growatt.tech. Accessories such as connection cables and backup boxes are listed as genuine parts with the same European service warranty.

Who do I contact first if my Growatt system stops working: the installer or Growatt?

The installer first. Growatt states plainly that it does not offer an installation service, so the firm that fitted the system is the route for physical inspection, replacement and safe isolation. Growatt's own support covers the equipment itself, warranty claims and monitoring. Keep the installation certificate, because the warranty period runs from the date on it.
