We put an RPS solar pump in for our garden irrigation a few years ago. That system has 400 watts of panels feeding the controller which supplies 24vdc to the in-ground pump and also maintains the 24vdc battery bank which is currently two each 100ah 12V AGM batteries.
SWMBO (my wife) wants to be able to have water running to the house in case of a hurricane or similar power outage. The line is already piped so all I have to do is open a valve to connect the solar system to the existing system.
I tried a 24v Shurflo pump that worked OK for a few months but now won't maintain enough pressure to run a sprinkler. It was recommended to go to a cast iron 1/2 hp 115vac pump. I have this one on order - https://www.lowes.com/pd/Acquaer-1-2-HP-Dual-Voltage-Cast-Iron-Shallow-Well-Jet-Pump/5001226199
This pump pulls 7.2 amps running on 115vac. It has a built in start capacitor. My in-ground pump fills a 1600 gallon storage tank set about 5 feet from where the transfer pump will be. I'll have less than 3 feet of vertical lift if the tank were near empty but when it's full, the pump is actually has 4+ feet of static pressure on the supply line.
What size & brand inverter should I look for. This will be an off grid installation and I'll probably need to run an auxiliary fan to help cool it. It'll have to be in a screen cage, too since it'll be under a shed and fair game for wasps here in central Fla.
Also, how many more 100ah AGM 12v batteries should I add to my bank?
Thank you for any info! I was a millwright/nuke pipe welder/machinist and I'm trying to learn the electrical side at 70!
