Just one battery pack for the 8KW Inverter?
Are you going to run 8KW just for short time?
48V 230Ah pack is not going run very long with 8KW load on the output of the inverter, the power input to the Inverter will be about 8KW/0.85 = 9.41KW, so the current at 48V (at low Voltage) = 9.41KW/48V = 196A, you are also going to need 250A BMS at the very least.
Two packs. I am not expecting to run 8kw for any sustained period (l expect to remain under half that most times, and likely less than that), but I am wanting to be sure that if I do pull max amount, worst case scenario, that nothing melts down.

Worst case will be 200A pull from one pack if the other pack went into shutdown.

I just got in 64 280Ah EVE cells from Doucan. I live off-grid and will be replacing my FLA's with these (excited!).
What kind of materials/setups are folks rigging up to compress the batteries (for those who do compress)?

Search for "compression" in title. Many threads on it, e.g.
diysolarforum.com
Pack / Cell compression Optimized By Using Springs.
I am opening this thread to split it off from the general cell compression thread. That way those looking for info don't have to sort thru a thread that has many paths for pack compression. If you are new to this idea, it stemmed from an EVE cell specification that indicated a significant...

I'm planning on using the Seplos case that's specifically built for this.
