I am having two Powerwalls and gateway 2 installed. I have been going over the installation manual to understand how everything works and make sure my installers do it right (I am their first install). Everything will be wired for whole-home backup with the Powerwalls and solar coming into the gateway 2, as well as the grid directly from the meter.
The gateway 2 comes with 1 CT (current transformer) and as far as I can tell it is supposed to be used to monitor the solar production. The Powerwalls monitor themselves and the grid is monitored already in the gateway. I am confused though on how the usage for the house is determined? The app is supposed to show usage for grid/solar/PW/home but only 3 of the four is monitored. Do I need another CT to monitor the house usage?
Thanks,
