    Wattage & VA rating cannot be determined from the battery ratings.All that this information can be helpful to calculate the back up time of batteries on load.The UPS rating can be determined based on the load connected to it.You have to study your load list & design the system.

    Is there no nameplate on the UPS, or manufacturers label, or instruction manual?

    The information you seek would be found in those locations.
