Could you please confirm the CT’s required for the 3 phase home installation in Australia?
The system already has SolarAnalytics wired in and its own CT clamps installed, however this only gives 2 free CT after it’s wired into the mains and solar . Given this, I’m looking at the IoTaWatt to run in parallel, so I can monitor ALL the mains/solar/air-con/household circuits, allowing me to see what is being produced / consumed where, and start getting data to plug into emoncms and its battery simluator to see about sizing a battery (& replacing small and old max. 3kVA inverter with larger inverter, so I can add PV panels as only 3kVA currently).
Not sure would larger inverter also mean 3phase to support 8-10kVA of PV panels (assuming its single phase currently, given the single orange switch)?
I know I need 3 x 100A CT for the mains, 6 x 50A for the power/light/stove, just not sure does the 3 phase air-con and the solar supply need 50A or 100A ?
Edit: Forgot to mention, looking to install a shed in future, but not being an electrican, but assume this means another run going to a sub-board on a future shed. At that point, would I be needing to install another v5 base and a bunch of 50A CT, to monitor the “mains” into the sub-board and the however many power/light etc circuits it ends up with?
