The invention discloses a monitoring and protecting device of a photovoltaic energy storage battery cabinet, belongs to the technical field of photovoltaic energy storage batteries, and aims to solve the problem that heat accumulation between batteries close to each other is difficult to solve in the conventional energy storage battery heat dissipation system. By starting the first exhaust fan and the second exhaust fan, under the action of the control mechanism, the valve plate does not close the second air inlet any more, air enters from the first air inlet and the second air inlet, and air entering from the first air inlet flows in the second branch air duct; then air at the position is mixed with air entering from a second air inlet and enters a first branch air duct together, at the moment, two air flows in the first branch air duct are subjected to heat dissipation, one air flow is subjected to heat dissipation, the other air flow is fresh air which is not subjected to heat dissipation, and in the state
