How to find minimum requirements for a energy storage system that needs to charge 2 batteries with following spec? 7660 mAh, 22.8 V, 176.93 Wh, 180W ?

These batteries are UAV batteries. I need the specifications of the energy storage system that will be powered by renewable energy sources and intended to use in off-grid. I would appreciate you...
