U.S. energy officials have launched an investigation after discovering unauthorized communication equipment embedded within Chinese-manufactured solar power inverters connected to critical infrastructure grids across the country.
This discussion explores the key communication technologies used by inverters, including wired and wireless systems, power line communication (PLC), standard protocols, and the integration of Internet of Things (IoT). Many solar inverters are equipped with wired communications such as RS485, Ethernet, or CAN bus.
In order to provide grid services, inverters need to have sources of power that they can control. This could be either generation, such as a solar panel that is currently producing electricity, or storage, like a battery system that can be used to provide power that was previously stored.
Energy security experts warn that coordinated remote manipulation of these devices could destabilize power grids and trigger widespread blackouts, particularly as Chinese-made inverters now control a substantial portion of renewable energy capacity in the United States and Europe.
