Deye, as a globally leading manufacturer of energy storage inverters, has always been committed to providing our customers with cost-effective and high-quality products. Our product failure rates are relatively low compared to our peers in the industry.During the past couple of years, the pandemic caused significant supply chain challenges, making it difficult to procure certain components while the demand for energy storage solutions surged. To ensure continuous product supply, we had to use alternative components. Please rest assured that all these alternative components are A-grade and have undergone rigorous testing to meet industry standards and certification requirements.The inconsistency between the components in our products and those mentioned in our catalog is due to our failure to update the catalog （2022-2023 Version）in a timely manner. We sincerely apologize for this oversight.
