Cybersecurity for the digital and sustainable energy transition

In an increasingly digital energy world, IT security is crucial. KOSTAL integrates cyber security as a company-wide principle - from development to production and support. Encrypted communication, personalised access controls and continuous software updates reliably protect the systems against unauthorised access.

KOSTAL records system data in compliance with the GDPR exclusively on servers in the EU. No personal data is stored on the inverters themselves. State-of-the-art encryption protects communication between the device and server - including digitally signed software packages.

KOSTAL combines data protection, cyber security and smart technologies to create a holistic security concept for the energy world of tomorrow. By choosing KOSTAL, you are investing in tested security and European standards - and in a networked, trustworthy energy future.

With a multi-level protection concept - consisting of a master key, service password and encrypted communication channels - KOSTAL inverters are reliably protected against manipulation and physical access. Even critical device settings can only be changed by authorised specialists.

As soon as new security or function updates are available, they are automatically transmitted in encrypted form to all KOSTAL inverters - whether via WLAN or LAN. Customers and installers do not have to do anything, but benefit from the latest security features and technological improvements at all times.

Before every release, KOSTAL software undergoes intensive penetration tests (white, black and grey box), some of which are carried out by external experts. In addition, all employees are regularly trained in IT security in order to recognise and prevent threats at an early stage.

KOSTAL stands for power electronics for solar systems from Germany with a comprehensive security and quality promise that convinces retailers, tradespeople and end customers alike.

The specialised trade benefits from a partner that proactively implements regulatory requirements - whether through early adaptation to EU directives such as the Cyber Resilience Act or through the integration of international standards such as ISO 62443. This security in product conformity creates confidence in sales and reduces the risk of complaints or rework. At the same time, KOSTAL offers comprehensive technical support, reliable delivery structures and a clear communication policy - decisive advantages for successful sales and strong customer loyalty.

For the trade - especially installers and service technicians - KOSTAL guarantees simple, safe and stable installations. The inverters have a multi-level access system with personalised passwords and master keys, which effectively prevents unauthorised changes. In addition, there are encrypted communication channels, automated software updates and an intuitive user interface that allows systems to be commissioned quickly and maintained reliably. This reduces effort, minimises risks - and increases satisfaction on the construction site.

End customers, on the other hand, can rely on a system that protects their personal data, is tamper-proof and is always up to date thanks to regular updates. The storage of all data within the EU and the deliberate omission of personal information on the devices themselves create a high level of trust. At the same time, the sustainable design, the energy efficiency of the devices and the transparent information policy ensure the long-term value retention of the system and the security of the investment.

Working with KOSTAL means choosing a partner who takes responsibility seriously - towards the market, society and the future. With sophisticated cyber security, technological progress and consistent European data protection standards, KOSTAL offers a strong basis for the digital and sustainable energy transition. An advantage that counts today - and will have an impact tomorrow.
