Can anyone help make a recommendation for how to power up our SMA Cluster Controller from a single leg of 277v from an ac panel? Something small that we could put inside the 2' x 2' x 12" enclosure with the Cluster Controller.

Extra points if it's a link to the Platt website!

Anything I need to worry about here code-wise?

There is no option to find any other panel nearby or existing circuit that is not 480/277

Thank you in advance!

It can be powered off of 24 VDC. While this isn't a single leg solution, I've used this three-phase power supply to power the SMA CC from 277/480V:

I have used this 277 to 24V power supply for cluster controllers with good results: https://www.alliedelec.com/phoenix-contact-2938730/70001025/

Just put it on a breaker and in a weather tight enclosure if outside and you should not have any code issues.
