Need help with new solar system

[Forbisher]

Aww... i was genuinely impressed with 8x 24v LiFePO4 batteries!

That would be $$$$$$$ lolz
I am noob but this post and a few others by new guys are very confusing due to not enough info and terminology.
Needs to be a post on how to ask questions. My psychic and guessing abilities are on overtime.
and most of these guys barely have a thanks for all the typing out of free advice.

I have 2 SCC's because the output of one is 20 amps ac and I want 40amps to tie into my home for emergency power to critical items.

Is this what you meant and does this explain it?
***********************************************
If I understand you on that 20 amps ac output.
The Output on the 40A 150V PV Input Epever Tracer 4215BN LOAD TERMINALS is 20A DC
There is no AC out of a SCC.
You get AC out of an inverter.
The LOAD TERMINALS are going to the light bulb in pic below.
Output is probably 24 volts at 20A but I am not sure about that?
The SCC would only output on the load terminal when the sun is shining.
Your Battery is for emergency power to critical items 24 hrs a day.
