I will be trenching and installing frost-proof waterline between a shallow well with a PV pump installation and a stock tank in a passive solar (earth banked) shelter located 730 ft away. I'm looking for recommendations on level switches that would be suitable and long term reliable for this job.
I tried doing it mechanically with a small bladder tank and pressure switch located at the well, but as the float valve closed it just chattered until it overflows, or it doesn't come on, depending on settings. Since there is the opportunity to run hard wire I would like to do this right.
The PV system uses (2) Dasol DS-A-18-90 panels, running at 24V through a Midnite solar combiner then a Shurflo 9300 Best Pump controller.
The level sensor is on a 120 gallon trough and system flow is only about 4-5gpm. It will be protected from cows but needs to withstand icing up, dirty water, etc.
There's so many options out there some help in narrowing down would be appreciated. This is the one DC system I deal with (other than equipment) and I'm less familiar with this world than AC stuff, I know exactly how I'd do it there!
Thanks
