I suspect I will get back "you get what you pay for" but seems like what I have should work....
I have a bank of 10 100A/hour AGM batters wired in 5 parallel banks for 24V output. I have a couple charge controllers keeping them feed from bunch of panels.
My static water level is about 40 feet down and I place the pump at the 90 ft level. It's another 60 feet from the well to the solar shed so I about 150ft of 8 gauge cable. I bought a 4" Solar Submersible Water Pump- 24 V - Direct DC - SPDC - SPDC24V/I-40-3-0.4-1 from pump supermarket and that lasted about a week. Got another one that one also lasted about a week. They run great and suddenly just stop.
I want to run my pump when it's not sunny out so that's why I run off battery.
Should go to a 48v system? Higher quality like RPS or Grundfos solve my problems?
