Wow where did you find that? I searched and searched don their website but did not find it. Where is it?
I don't believe SolarEdge currently has it uploaded. This is something you have to request by email from infoNA@solaredge.com, and keep on file for your project if you need to justify your design.
I have not explored whether their 208V grid inverters can be connected to a delta system without a neutral. I recommend contacting SolarEdge to clarify whether this is a possibility, if it is important to a particular project.
