Posibility of T12-G3 unbalanced mode and use two smart meters

Hello,
can my FoxESS T12-G3 inverter operate in unbalanced mode? Is there such a possibility?

Also, can I use two DTSU666 smart meters (by configuring them with different address values) to connect an additional generation source, so that my current inverter would be able to track its own (smart meter Addr=1) and additional generation (smart meter Addr=2). I have seen a similar diagram in the H3 hybrid inverter user manual (in case when trying to install extra third-party inverter), but I don’t know if it would work with my T12-G3 model. Would the T12-G3 technologically cope with two metering devices at once?

Thank you very much for your answers in advance!

Not good news here i’m afraid.

The 3 phase T series is a balanced output, all phases output at the same power it does not support un-balanced mode.

You cannot connect a T series in the same way as you can a hybrid inverter with a second meter to monitor other generation sources - there may be an option to connect multiple T series together for what Fox calls anti-backflow
