SPH/XH ATS 11400T ( 50A, up to 5kW secondary circuit)-$897

They are from

So for me.. Looking at the 10000TL-XH
I would also need an ATS, so maybe the SPH/XH ATS 11400T. Not sure the difference between the the 11400T and 5000T as they both say up to 5kW Secondary circuit.
If I get my permit from my hydro company I might skit the Smart Meter. I am not sure what it gives you if your able to export to grid.
I found this diagram helpful for me to wrap my brain around the wiring:

I took this from Growatts installation guide found here:

page 29
I need to read more about the ATS and the batteries they support.
