Cybersecurity is the foundation of networked energy systems. Inverters and wallboxes must guarantee integrity, data protection and regulatory compliance. KOSTAL combines security-by-design with clear responsibility and European standards - for long-term stability, planning security and trust in the digital energy world.

For installers: technology you can rely on.

Installers today integrate more than just electrical components. This results in an extended responsibility for safe commissioning
and stable system architectures.

• Protected commissioning processes
• Structured user and role management
• Controlled interface releases
• Future-proof firmware updates

This creates planning security - both technically and from a regulatory perspective.

For retailers: security as a product range feature.

The selection of a manufacturer influences product quality, availability and increasingly also regulatory risks and reputational issues.
A transparent security strategy therefore becomes a relevant decision-making criterion.

• Clear localisation of development in Germany
• EU-compliant data storage
• Transparent security architecture
• Preparation for regulatory requirements
• Sustainable product and update policy

Cybersecurity contributes to the stability of the entire supply chain.

For plant operators: Protect your data. Control your energy.

Networked energy systems provide transparency and convenience. At the same time, new requirements for data protection and access control are emerging.
KOSTAL takes a responsible approach here.

• GDPR-compliant data processing
• Transparent server locations
• Controlled remote access concepts
• Encrypted communication channels
• Long-term update capability

This means that sovereignty over energy and system data remains within clearly defined structures.

The safety architecture of inverters and wallboxes is based on several coordinated levels. Technical protection mechanisms interlock and are supplemented by clearly defined organisational processes. This creates a multi-layered security concept that takes equal account of integrity, availability and confidentiality.

Central elements of this architecture are end-to-end encrypted data communication, authenticated device and user access and digitally signed firmware updates that reliably prevent tampering. This is supplemented by controlled access to interfaces, structured network segmentation and regular security checks. Documented development processes also ensure that security requirements are systematically taken into account and continuously developed. The interplay of these measures creates a high degree of system integrity and technical sustainability.

At the same time, the legal requirements for digital products are evolving dynamically. Manufacturers, retailers and specialised companies are increasingly responsible for taking regulatory requirements into account at an early stage and aligning their systems accordingly. The relevant framework conditions include the NIS2 Directive, the Cyber Resilience Act and requirements in the context of critical infrastructures.

KOSTAL is already integrating these regulatory developments into its strategic product planning. This results in solutions that not only meet today's security requirements, but are also prepared for future requirements. For retailers, tradespeople and operators, this means long-term planning security and a resilient foundation for the digital expansion of the energy transition.

Safety requires clear responsibilities and comprehensible responsibility structures. Development, quality assurance and strategic product management take place at KOSTAL in Germany. This organisational location creates short decision-making paths, a high level of transparency and reliable support structures. At the same time, it enables sustainable product cycles with a long-term update and spare parts strategy. Responsibility and control thus remain clearly assigned - both technically and entrepreneurially.

The inverter, battery and wallbox are not isolated individual products, but integral components of a networked energy system. Their architecture is harmonised and follows a consistent system logic. This reduces interface risks, harmonises safety mechanisms and standardises update processes. Transparent communication structures also ensure clarity in operation. Such a system approach increases stability, improves the integrity of the overall solution and reduces unnecessary complexity.

Cybersecurity is the basis for ensuring that photovoltaic systems and charging infrastructure remain stable and reliable in the long term. Only if systems are protected against manipulation, unauthorised access and technical faults can downtimes, operational interruptions and economic losses be avoided.

Today, digital energy systems are networked systems. Their availability depends not only on electrical quality, but also on stable software, secure communication and controlled update processes. Security therefore means one thing above all: predictable operation without unexpected downtime, trouble or loss of revenue.

KOSTAL stands for technological expertise, European standards and data sovereignty. For long-term stability in operation. And for responsibility in development, implementation and continuous further development.
