We have an FDM 1650 with UPS. I will have to check on the exact rating
but the overall logic for selection went like this.

The system requires high power at only at start time hence if you plan
for a capacity slightly higher than that for 15 or 30 mins, it should
last you for quite sometime.

The other criteria is the probability of power failure in your area and
for how long. We are blessed, being in a fairly developed city like
bombay not to have so frequent power failures. Hence we decided to have
a battery back up for about 4 hrs. The entire unit alongwith the
batteries costed us approximately 2.5K USD equivalent.
