Abstract

The invention discloses a photovoltaic optimizer aging device, which comprises a main body case, and is characterized in that a DC power supply array module, a confluence module and an inversion module are arranged in the main body case; the DC power supply array module is connected with the input ends of a plurality of tested photovoltaic optimizers; and the confluence module is used for connecting DC outputs of a plurality of tested photovoltaic optimizers in series, and the output end is connected with the inversion module. The DC power supply array module is used for simulating the working state of a photovoltaic module and providing DC input of the photovoltaic optimizers for the plurality of photovoltaic optimizers, the confluence module is used for connecting the plurality of photovoltaic optimizers with the inversion module, and the inversion module is used as a load in the aging process of the photovoltaic optimizers and can perform batch aging test on the photovoltaic optimizers, so that the photovoltaic optimizers can be subjected to aging test, the aging test efficiency of the photovoltaic optimizer is greatly improved, and a foundation is laid for large-scale production of the photovoltaic optimizer.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic power generation, and in particular relates to an aging device for a photovoltaic optimizer. Background technique [0002] The photovoltaic optimizer can realize maximum power point tracking (MPPT) for each photovoltaic module, so as to ensure that each photovoltaic module in the photovoltaic system can output electric energy to the maximum. It also has energy transmission, energy optimization, data acquisition and communication functions, and is suitable for use in mountainous areas and areas with severe roof shading. [0003] The aging test project refers to the process of simulating various factors involved in the actual use conditions of the product to carry out corresponding condition strengthening experiments on the aging of the product. Aging refers to simulating a test environment under high temperature and harsh conditions. Long-term burn-in of performance electronic products ...
