Manual says peak ~1.6KW, but the inrush on a dry coil can run up to 10x the working load, especially when modified sine power is involved.
Suggest minimum 5KW generator; while a smaller one (say, 3750W) might work, you're left with no headroom.
This is also a big enough load that (1) a lossy wiring run can be problematic (2) wiring for 220 is a clear win (in which case a 5KW is usually the smallest generator with a 220 tap).
Alternate solution: DC-powered backup pump. Possibly cheaper than a generator.
