Install a dedicated firewall specifically for your renewable energy system, and ensure all communication channels are encrypted. . Solar energy technologies can be vulnerable to cyberattack through inverters and control devices that are designed to help manage the electric power grid. Operating-technology (OT) devices like solar photovoltaic inverters, when connected to the Internet, are at higher risk relative to stand-alone. . This report provides practical cybersecurity guidance for small-scale solar inverter implementations that are typically used in homes and small businesses. These guidelines are informed by a review of known smart-inverter vulnerabilities documented in the National Vulnerability Database (NVD), a. . As solar energy systems become more connected, their vulnerability to cyber threats grows. Typically when information won't leave the property, there is an issue with onsite firewall not letting information leave.
