@pedro yes, one CT goes around the solar feed cable, and the other goes on all loads, including the EV charger. The latest diagram from the new installation manual in quite clear.
The problem with this setup is that it can be extremely difficult to place a CT clamp around all the load cables and the EV charger cable. This is why most other EV chargers locate the CT around the main grid feed cable (1 cable) and solar cable, then measure the difference between the loads and solar.
The 3-phase version is the same, except across the 3 phases.
