Yes, but with a limited cycle life of typically 300 or so for AGM, significantly reduced if the battery is ever more than 50% discharged. Also high losses in charging, and needing an extended duration of high voltage low current charging to get to 100% from 80%

For larger applications you don't use agm, you often go back to flooded batteries with even replaceable, high cycle cqthodes: https://www.sciencedirect.com/science/article/abs/pii/B9781782420132000030
