Clay should avoid these at all cost.
MGE rather usefully do a runtime calculator where you put in the power
draw and required runtime and it suggests options from their range.
Worked like a charm when I used it, however there's a gotcha. An ups
with a 28 minute runtime may signal LB at 19 minutes, resulting in a
shutdown sometime sooner than you expect :)
If you need a 20 minute actual runtime you'll probably need a 30
minute theoretical runtime.
