How many amperes does the fuse of a lithium battery use
240KW/400KW industrial rooftop - commercial rooftop - home rooftop, solar power generation system.
I guess that you use 12V car batteries. The voltage can drop by large currents to 11V. P=U*I 1000W / 11V = 90A 90A /3 car batteries = 30A. You can use a 32A fuse for each battery.
