Recently Willem Westerhof published a study on cybersecurity threads regarding PV inverters, in which SMA was mentioned. 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.
