DYI off grid with Bluetti feedback appreciated

[WCC]

Hello
So my house has a transfer switch installed to the main panel and the panel has a generator interlock switch installed.

My plan is to go totally off grid and to store my own power. And here is my equipment.

- Two Bluetti AC500 inverters with fusion box (240V/10KW Split Phase System)

- Three to Four BC300S Batteries (9-12kW)

- Nine 345w Solar Panels (ground array)

Once everything is complete I would connect the fusion box to the transfer switch via cable. At the main panel I would utilize the generator interlock switch to disconnect from the utility company and switch over to the solar generator system for whole house power.

Thoughts???

You need a power audit to determine system size requirements, is your range, hot water, dryer ng or lpg do you have a well pump or city water these items are heavy loads requiring large systems

According to my utility bill, I used 1670 kWh for my highest month.
