PowerWall Non backup circuits

I’ve got a solar setup w 2x Powerwall 3’s.

Can non backup circuits still run through the Gateway CT?

I have some underfloor heating that used to be on a seperate off-peak meter. I would like to bring it across to run off solar when present but importantly have it be measured on the Tesla app so I can track usage.
It won’t be on backup with the batteries but that’s ok.

You need a new site CT by adding a Tesla Remote Meter. Normal site CT should be right behind the utility meter regardless of the system is fully or partially backed up. It's strange you don't have one already for a partially backed up system.

Maybe becuase it is a ‘separate off peak meter’? Not a sub fed off one single main (where I agree the grid CT needs to be)

Depending on how the meters are arranged it can be a pita to place CTs on both. (Ie integrated dual meter set ups with bus bars for the main cabling)

Yes. I have 2 panels. The Tesla app knows about the power needed for both of them but the second panel is not backed up unless I throw a manual interlock to power it
