1 big batteries or several smaller

[Bob Smith]

Hello

a part of some obvious advantages such if the big one fails, no more batteries, if you have one small that fails the other still works. I am looking at the discharge power.

I would like to know if my comparison is correct.

Big battery: Discharge 4.5kW
Small battery Discharge 1.5kW

If I have 3 small batteries, will I be able to get 4.5kW in my house (if I have many devices on at the same time) and get the same power as if I had a big battery.
(Assuming the batteries are all charged blabla...)

What should I consider too?

Thank a lot for educating me

Don't quote me on this as I haven't done any battery installs, but i think the possible power output is more reliant on the inverter used. And many of the biggers batteries are made up of smaller unit anyway. Though may not be servicable down to those levels.
