Has anyone integrated FCS-King-5000 inverter to OEM?

Hi all,
Due to our local utility supplier basically in the process of collapsing we having to look at putting something in place to survive…

I’m look at putting down a FCS-King-5000 Inverter + 8 x CSB 12390W batteries and 12 x Renewsys 330w panels.
What type of data can I potentially ingest from the inverter, what should I be looking at putting down for the batteries and panels ?
