Chint 666 alternative?

[casper2]

I help a customer with his site.
He has now increased his connection from 63A to 650A
And in the new electrical cabinet there is a smart meter from Gavazzi, which then does not have its parameters on the same register.
Then thought of throwing in a Chint 666 CT, but then it has a maximum of 250A according to the maual. So do you know any meter that works with FOXESS inverter and can have CT 750/5?
