1. A modular redox flow battery comprising a positive electrolyte tank; a negative electrolyte tank; a positive electrolyte; a negative electrolyte; a plurality of stacks; pipes; a positive electrolyte pump; a negative electrolyte pump; a battery management system; and sensors,
wherein the stacks and the battery management system (500) are mounted on a stack frame (800),
the positive electrolyte tank and the negative electrolyte tank are mounted on a tank frame (900),
and the stack frame (800) and the tank frame (900) are combined, and
wherein the positive electrolyte tank and the negative electrolyte tank are in the form of a rectangular parallelepiped in which a portion is removed,
a space (260A) for mounting the positive electrolyte pump or the negative electrolyte pump is formed in a place where the portion is removed,
a pump support frame (700) including a vibration absorber is connected and installed to the tank frame (900) in the space (260A),
and the positive electrolyte pump or the negative electrolyte pump is installed on the pump support frame.
