Title:
PHOTOVOLTAIC INVERTER AND CONTROL METHOD AND APPARATUS THEREFOR, AND READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/041106
Kind Code:
A1
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; and each photovoltaic module performs corresponding energy acquisition at an adjustable maximum power, thereby ensuring the full utilization of energy, such that a higher working power can be provided while the safety of the inverter and modules is ensured.
