Abstract: A photovoltaic inverter and a control method and apparatus therefor, and a readable storage medium, which relate to the technical field of information. The control method is applied to a multi-channel photovoltaic inverter. Separate power limitation is simultaneously performed on the power of the whole machine of the inverter and the power of each channel of the inverter, such that there is no need to fix the operation power of a single channel, and it is only necessary to determine whether the operation power exceeds a safety range. Compared with previous control methods for a photovoltaic inverter, when the same input energy is acquired, the maximum power that matches the whole machine is acquired first, such that the whole machine is prevented from being damaged.

Abstract: A distributed photovoltaic system includes N first photovoltaic modules each configured to convert solar energy into direct current power, N energy storage modules, and N inverters. Output terminals of the N first photovoltaic modules are connected to input terminals of the N energy storage modules in one-to-one correspondence. Output terminals of the N energy storage modules are connected to first input terminals of the N inverters in one-to-one correspondence. Output terminals of the N inverters are connected in parallel at a joint connected to a power grid or load. That is, a single energy storage module is connected to a single photovoltaic module and a single inverter, so that the single energy storage module is small in capacity and low in power. In addition, different energy storage modules are scattered.

Abstract: A method and a device for a current source to respond, and a computer-readable storage medium are provided. Parallel control for the current source and a voltage source is established, and a voltage across an alternating-current bus is acquired. When the voltage is lower than a first threshold, the current source outputs a current to increase the voltage across the alternating-current bus. Then, it is determined whether the voltage exceeds a second threshold. When the voltage exceeds the second threshold, the current source stops outputting the current. When the voltage does not exceed the second threshold, power is distributed between the current source and the voltage source after power synchronization. The current source directly outputs the current, and therefore unnecessarily wait for the power from the voltage source.

Abstract: A method and an apparatus for controlling a shutoff device, and a shutoff device. The shutoff device includes N main switching transistors and N bypass switching transistors. The method includes: controlling the N main switching transistors to be turned on after receiving a heartbeat signal; determining whether a power supply voltage of a processor is less than a first under-voltage protection voltage; and if so, controlling the N main switching transistors to be turned off, and controlling the N bypass switching transistors to be turned on. Thus, N photovoltaic modules and N main switching transistors corresponding to a shutoff device are separated from multiple photovoltaic module groups, so that the photovoltaic module groups corresponding to other shutoff devices can normally output DC voltage to an inverter, and the inverter can normally output AC power for integration into a power grid, thereby ensuring the normal operation of the photovoltaic system.
