‘We have a real adversary’: Work intensifies to safeguard solar from cyber attacks

Solar inverters are increasingly smart, but their sophisticated power electronics expose potential cyber security gaps. Work is underway to harden the devices from intruders who may be out to cripple the electric grid.
