An over-
temperature load reduction device and method for an integrated optical-storage
inverter, the integrated optical-storage
inverter includes a photovoltaic boost module, a battery buck-boost module and an
inverter module, a temperature acquisition unit of the photovoltaic boost module and / or a battery Buck-boost module temperature acquisition unit, inverter module temperature acquisition unit, optical-storage integrated inverter temperature acquisition unit, switch unit, over-
temperature load reduction strategy unit, photovoltaic boost module load reduction
control unit, battery buck-boost module drop-off
control unit The load control part and the load reduction control part of the inverter module. When the solar-storage integrated inverter is running, the over-
temperature load reduction device also continues to operate. For an optical-storage integrated inverter with multiple inputs and the same module switches between input and output in different
modes, a device and method for how to specifically limit the input power of each channel after limiting the output is provided, which effectively controls the optical The overall temperature of the integrated storage inverter when it is working can effectively suppress the main heat source of the integrated
optical storage inverter and prolong the life of the
machine.
