Hoymiles, a Chinese company founded in 2012 by Yang Bo and Zhao Yi at Zhejiang University, specializes in the production of inverters for balcony power plants. The firm’s products are frequently mentioned by providers of these micro-solar solutions due to their compact size and integration capabilities with existing solar panel installations. However, a significant issue has been brought to light regarding one of its key components: the Data Transfer Unit (DTU). According to recent reports from users and an investigation by the Bundesnetzagentur, the DTU W-Lite S model used in some inverters is causing substantial radio frequency interference in the 868 MHz band. This interference can disrupt other wireless devices such as DECT phones, remote controls, routers, among others, leading to connectivity issues for homeowners and neighbors alike. Marvin, a user who contacted me about this matter, has observed similar disruptions at his own installation site. He noted that the DTU W-Lite S appears to continuously transmit in the 868 MHz band which is prohibited by law as it interferes with other critical wireless communications. This issue raises important questions about compliance and safety standards within the industry for such innovative solar solutions, highlighting the need for stricter regulations and better testing procedures before these products are made available on the market.
Hoymiles DTU W-Lite S: A Cause of Severe Radio Frequency Interference in Residential Networks
The radio frequency interference caused by Hoymiles’ DTU W-Lite S is a serious concern for homeowners and network operators. This issue not only affects the performance of wireless devices within affected homes but also has potential implications for broader public communication systems that operate on similar frequencies. The discovery of these problems by users and regulatory bodies underscores the importance of thorough testing during the development phase to ensure compliance with existing legal standards and the minimization of adverse effects on other radio-based technologies.
