Need help upgrading my UPS ME-2000-VU+

[isie]

So I ran a discharge test on the unit to sort out the permanent fault error yesterday.

The UPS took 5 hours and 52 minutes ( lets say 6 hours) to completely discharge the internal batteries with no load connected.

Based on this the UPS itself uses up 48 watts. The load according to the door manufacturer is 300 watts when running, BUT with an extremely high startup current (do not what this just that it is extremely high).
The total load is thus lets say 350 Watts when running. The assuming run time for the door to close or open is 60 seconds. That means about 0.24 AH. Hence the unit will be able to run the motor provided it can cope with the startup current.

Will report back when I know a little bit more about the load.

But my opinion stands. This UPS is not suited to act as a back up for this type of load, and should never have been sold to a customer by a garage door installation outfit.

first thing i didn't read all the posts, so if this has been said sorry.
but motors don't like modified sine wave power, they run hotter and use about 30% more power then if it was pure sign if i remember. So this will drain batteries even faster - then the whole inverterting part add to the inefiicincy (24v to 240v and then sometimes back to 12) hence most motors run on 12 or 24 v directly off the batteries and power is only used to charge up the batteries

though knowing this i actually tried this particular ups on my old garage motor, couldnt get 10 minutes, though i used it more as a way to have a plug in the garage rather then a back up (motor was on the light switch)
