[Nut-upsuser] MGE Ellipse Max 1100 configuration question

Servers, workstations? You have multiple devices connected to this system?
See my previous message, your UPS doesn't have the capacity to power more
than a small server or maybe two workstations (if you're lucky).

You should *never* connect a printer to the battery backed up output of a
UPS. Especially laser printers draw huge amounts of power while powering
up. A small SOHO type UPS is not able to cope with that.

I think 3% is the value that would be indicated when the load is
essentially shutdown. Note that 3% is a load of only 33VA.

That is too much. Assuming a reasonable power factor which you can expect
nowadays, the real load will be close to

	55% x 1100VA = 605W

As written before, the maximum load on your UPS is just 660W. At startup,
this will more than likely be more than 660W (harddrives spinning up), so
I think you'll need to lower the load on your system. I don't know why the
system shuts down when you fire up the driver, but it could be that the
UPS uses slightly different thresholds depending whether it is running in
managed or unmanaged mode. Unless you run the driver with the '-k' option,
it will not send the UPS a command to shutdown the load.
