that is at 0 psi
a good grundfos sq spec manual can be found here
don't know if they are a good company just the first real graph I found!
looks like the best you will do with that setup is a 22SQ/SQE10C-190
which will put out 16.5 gpm @ 140feet with 40 psi of pressure use a 20/40 pressure switch and it should work for you.
I have a 5gpm 1/2 hp sq and it really does have a zero surge start, they work great and if my 1/2 hp pump is any indication, I would expect this pump to pull 2kw when running full blast ( my 1/2hp NEVER pulls more than 1kw) again zero surge start.
I would bet money th ob inverter will push this fine as my vfx3236 pushes my 1/2 hp pump fine even when I am using my 1800w induction cooktop on high.
the sq I use actually starts out lower than 1kw (about 750w) and climbs there over several seconds.
well that's 3 posts in a row plugging the sq guess I better back off
swear I'm not affiliated w/grundfos in any way I just love my well pump. It works exactly as advertised. and I'm tired of seeing the extremely overcomplicated systems many installers push for, when the sq is reasonably priced and works great. (I know it's not as efficient as some but it is cheaper and higher quality take the money you save and buy more panels)
