[RE-wrenches] Solar edge question

[Jay]

Hi all

For all you SE experts. 

I got contacted from someone who has an offgrid system of a SE 7600A and battery. Works fine. 

They want to connect to grid power, which is right at the street because they want an EV. 

My question is, what do they need to make this a normal sell back and battery backup ( for a sub panel). 

Is it just the SE energy hub backup interface?  Or?
And does the 7600A work with that?

Thanks in advance 
Jay
