【Abstract】 In order to avoid the off-grid photovoltaic energy storage integrated machine in the long-term outdoor work, due to structural rigidity and strength problems, vibration and looseness occur, firstly, static and modal analysis was performed using ANSYS Workbench software. According to the analysis results, the weak design of the integrated off-grid photovoltaic energy storage machine is optimized and improved. By comparing the static and modal analysis before and after optimization, the optimized integrated off-grid photovoltaic energy storage machine effectively improves its vibration. Characteristics, and effectively avoid resonance with the transformer module, its structural rigidity and strength are also significantly improved. The optimized design provides a method and basis for the design and improvement of the integrated off-grid photovoltaic energy storage machine.更多还原
