How to change inverter into UPS

Air-conditioning maintenance workers don't pay much attention to electronic circuits, hehe, the landlord posted the wrong post, but ups is also an inverter.

In this case, the length of the delay is only related to the capacity of the battery and battery pack. I changed it, and the effect was not satisfactory. The charging current does not reach the nominal charging current for replacing batteries and battery packs. '
