How to load the UPS with incandescent lamps?

Question

System administration

There is a UPS park from APC (smart 1000, 2200) about 60pcs.
Often you have to perform calibration, and for this you need to organize the load on the UPS in the region of 30-40%.
There was an idea for this to make a "battery" of incandescent lamps (7x100W) in order to make it more convenient to transport.
The device assembled and ran into a problem.
When the UPS is connected to the mains, the lamps are on, but the load on the UPS does not increase.
When the UPS is disconnected from the mains, the lamps go out. At the same time, other devices connected to the UPS continue to work (that is, it’s not the UPS at all).
Can anyone advise on this matter? I do not want to abandon the idea of ​​​​such a device, because the organization of the load every time is a big problem.

Answer 1

Did you put the lamps into the bypass socket for an hour?

Answer 2

use an iron

Answer 3

That's interesting, I didn't think about that load.
And these UPSs do not directly supply voltage when working from the mains? Or from a battery?

Answer 4

UPS Smart-UPS 1000VA Line-interactive, this means that while there is voltage in the network, it goes directly, skip at least 10 kW there (I exaggerate of course), the load will be if it is disconnected from the network.

Answer 5

This is some kind of miracle, but miracles do not happen ... For some reason, the voltage from the inverter is enough for a computer and not enough for a light bulb?
In the evening I will connect a table lamp with an incandescent lamp to home UPS's, I'll see, I'll measure the voltage.
At home, LED and fluorescent table lamps are constantly connected to them - they normally shine both from the network and from the battery.
Now at work and there is nothing suitable to try.
