Thanks for double checking. It's not for my project, someone else's on the forum actually. So I'm not really the person to talk to about that. But here is my paper trail.
CEC for the hybrid. I didn't see the Autotransformer + Automatic Transfer Switch combination, I don't know if it's listed separately.
It's possible this anyway cannot be used, if the ESS it comprises (along with the battery) is not yet CEC approved. CEC has blessed part of the system, is the only positive evidence the paper trail below indicates. The AT is interlocked away from grid power by the ATS in this device so I'm not sure its existence matters for interconnection purposes, since it cannot be paralleled with grid.
