Recently Willem Westerhof published a study on cybersecurity threats regarding PV inverters, in which SMA was mentioned. The topic has also since been seized upon by other media outlets. Unfortunately, the claim has caused serious concern for our customers. We would like to stress that SMA does not agree with this article, as some of his statements are not correct or greatly exaggerated.
Please be assured that the security of our devices has highest priority for SMA in all respects and that we do everything we can to protect our inverters and communication products against cyber-attacks. We already assessed the mentioned issues on a technical basis and work intensively on the correction. The stated potential security issues only affect older SMA products and only a very few products in our portfolio. To maximize transparency, we use this website to explain the background and correct the facts.
As mentioned before, cybersecurity is an extremely important topic for SMA. We are continually working on implementing the highest security standards and measures with our devices in order to make them invulnerable to attacks. In this respect, we also continually ask our customers, to read and adhere to our public cyber security guidelines in order to prevent possible attacks.
