Why your photovoltaic system needs Guardexy
Corporate photovoltaics have long been more than just a source of energy — they are digital infrastructure. And every digital system can be exploited. Today, companies work with smart inverters connected to the internet, cloud monitoring, remote management, and automatic updates.
All of this creates a new vulnerability, which is also addressed by the new Cybersecurity Act (NIS2). With Guardexy, you will meet new security requirements and protect your photovoltaics from cyber threats. On sale from December 2024.

Frequently Asked Questions
Why should I address this right now?
Timely prevention is always cheaper than dealing with the consequences.
Because cyberattacks on internet-connected devices are increasing — and photovoltaics are no longer an exception. Most modern inverters communicate with manufacturers’ clouds (often outside the EU) and send data about your power plant. Guardexy acts as an active protective filter that prevents unauthorized transmissions and protects your investment and data.
What are the risks if I do not protect my power plant?
Unprotected PV = an open gate to the network.
Your power plant can be remotely shut down, throttled, or exploited for attacks. Through a vulnerable inverter, an attacker can also gain access to your home network, including your computers or smart home devices. Guardexy can detect, block, and report these attempts before they occur.
How do I know if my power plant is vulnerable?
Are you online? Then you are a target.
Whether you only own a mobile phone or other smart home devices: if your inverter has remote access, a cloud connection, or a mobile app, then it is online – and therefore potentially vulnerable. Guardexy offers the same solution that your computer likely uses: a high-quality firewall, a shield against unwanted data traffic and commands.
Does Guardexy work with my type of inverter?
Compatibility is broad and we are constantly expanding it.
Guardexy supports all common brands (Solax, Goodwe, Growatt, Huawei, Sungrow, etc.) and works independently of the manufacturer. It monitors data traffic at the network level – so it does not interfere with hardware or void the warranty.
Can Guardexy slow down data transmission, for example?
Security without compromising on speed.
The device works passively in real time – it checks data flows without delay, without interfering with operations, and without affecting performance. All transmissions that are secure and authorized pass through completely freely.
How is Guardexy installed and who will do it?
Plug it in – and you’re all set.
Installation is plug-and-play: it simply connects between the inverter and the router (or LAN switch). Any electrician or installation company – or our partners – can handle it. The entire process takes a few minutes, without any power plant downtime.
How much does Guardexy cost and what do I get for it?
A one-time investment, long-term security.
You get continuous 24/7 protection, data transmission monitoring, automatic updates, and threat warnings. The price depends on the size of the power plant – it ranges in the thousands of crowns per device. More in the “Products” section.
What happens if Guardexy stops working?
A security layer that never slows down production.
Guardexy is designed not to affect PV operations even in the event of a failure – production continues. At the same time, the system automatically reports that it is out of operation, so you will be informed of the problem in time.
How does Guardexy differ from a standard firewall or router?
A firewall for the solar world – tailored specifically for PV.
A router protects the home network; Guardexy protects the inverter itself. It analyzes traffic specifically for photovoltaics, recognizing the difference between normal communication and suspicious data transmission. Additionally, it detects external connections outside the EU and maintains evidence logs for audits or insurance companies.
