You are probably right, but - considering the operating voltage range of
the SQ, (100 - 130 VAC), and the flexibility in allowable frequency (50
- 60 Hz), these pumps are obviously made to be usable in variable
situations. I spoke with one of the Grundfos engineers a couple years
ago about inverter applications and was told that they did have "just
about every possible power source in mind" when designing this line.
Aren't we glad they did?
