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.
U.S. energy officials are reportedly reassessing the security risks posed by Chinese-made components in renewable energy infrastructure after discovering hidden communication devices inside certain solar inverters.
These inverters, which are essential components that convert direct current from solar panels into alternating current usable by the electrical grid, were found to contain undocumented cellular radio devices not disclosed in product specifications or technical documentation.
However, rogue communication devices not listed in product documents have been found in some Chinese solar power inverters by U.S experts who strip down equipment hooked up to grids to check for security issues, the two people said.
Central inverters are a time-tested solution with a lower upfront cost, making them a great option for large-scale systems without shading concerns. String inverters convert DC power from “strings” of PV modules to AC and are designed. . There are three primary types of solar power inverters used in solar energy systems: string inverters, central inverters, and microinverters.
