[RE-wrenches] Off-grid deep well pumps

[Dana]

We have had several CU200 fail they are not the most stable controller & I do not think that they are required.  The soft start is built into the motor on the pump.

Hi All,

I'm trying to locate archives about deep well pumps with little luck. 
Particularly information comparing Grundfos to other viable options (for a pump at about 200 feet with a static water level of about 70 feet) 120vAC off-grid VFX3648 system. I am just making a recommendation to my client, and have seen the Grundfos controller be somewhat susceptible to lightening surges, which is likely to be an issue in this location.  If someone could point me to pertinent threads, I'd appreciate it.  Or if anyone wanted to chime in with their own experience, that would be very helpful.

Thanks in advance,
Howie
