Inspection Firm Hacks Inverters Within Minutes, Casting Doubt on Security

By [email protected] The standards body TÜV Rheinland has cast doubt over inverter makers’ cybersecurity measures after it hacked commercially available PV inverters “within a few minutes.”

The Cologne-based organization stated that the finding was “all the more critical since storage systems typically communicate with the inverter, too.”

By hacking inverters, cyber criminals could gain access to battery management systems and trick batteries into operating in unsafe modes, TÜV Rheinland said.

On a wider scale, it might be possible to attack the entire electricity grid, causing massive power fluctuations, the researchers warned.

“We were able to re-parametrize commercially available inverters without any problems,” said Roman-Alexander Brück, laboratory
