Grid monitoring of large supplies for ESS

Hi All, does anybody know if there is a Victron preferred method of monitoring the grid connection in an ESS where the size of the supply exceeds the capabilities of the ET340 (65A per phase) and the standard Victron 100A CT? I think this system will be connected to a 250A three phase supply (still having the supply confirmed)

Can I just connect another Carlo Gavazzi meter like EM271 and expect it to work out of the box?

From the manual: https://www.victronenergy.com/upload/documents/Energy_Meter_ET112/113406-Energy_Meters-pdf-en.pdf

" Q7: I want to use Current Transformers (CTs), is that possible?

Yes. You can buy a CG EM24DINAV53DISX, a CG EM530DINAV53XS1X or the CG EM530DINAV53XS1PFC directly from Carlo Gavazzi or one of their distributors. Even though Victron does not stock that type of meter, we do support it in our software. "

EM530 accepts CT with 5A Output and up to 10kA on primary side.

Have a look here, as an example: https://www.gavazziautomation.com/nsc/HQ/EN/group/WC000002V39?WFCURTRAF2_C2000005=C2000005V2
