Why is cybersecurity important in PV systems?

Solar systems are a smart investment—but without proper protection, they can become an entry point for cyberattacks. PV systems are connected to the internet and, without protection, can be hacked like any other internet-enabled device. A cyberattack on a solar installation can have serious consequences:

Targeted burglary
cybercriminals can analyse energy consumption to determine when a home or business is unoccupied and what valuable devices are present.
Involvement in cybercrime
stolen credentials and hijacked systems can be misused for criminal activities.
Leakage of sensitive business data
for commercial customers, a compromized PV system can expose operational data—with financial and legal consequences.
Disruption of energy flows
a hacker attack can interrupt the power supply and disable electrical devices.

SMA integrates cybersecurity into every system so that PV installations remain protected at all times.

For the home

A PV system knows when someone is at home. Hackers know that too, if the system is not protected.

SMA ensures:

... that data is secure.
... that the power supply is assured.
... that updates occur automatically—without any manual effort.

Uninterrupted operation

A hacked PV system can leak sensitive data or interrupt the power supply.

SMA ensures:

... that installers comply with EU law such as NIS2 and GDPR.
... that operational data is protected against leaks.
... that downtime and costly remediation are avoided.

Cybersecurity for PV Systems for businesses

With SMA, installers and their customers benefit from:

... simple setup with integrated security standards.
... fewer service visits thanks to integrated updates.
... certified protection to ISO 27001 and ETSI EN 303 645.
