This is true, especially for low frequency (high mass) inverters. The inverters that are covered here are overwhelmingly high frequency (low mass) inverters. We hope that they practiced great electrical engineering and layered multiple layers of physical safeguards on top of the software based controls built into the firmware.
Of course a company that skimped to the point of total neglect on software security would never skimp anywhere else, right? Right?
:crossed-fingers: <- This is what we are relying on here.
And even if they did all the right things with their physical safety, the attackers can still brick the inverters with bad firmware and make them require a high skill firmware restore at a minimum and turn them into e-waste and require an re-install from a licensed electrician at a maximum.
