New member, old question on converting existing pump to solar
Hello all, new member here.
I am researching for my first solar project, which will be to migrate my house well pump from grid to off-grid solar. The primary goal is for water supply independence in the event of extended power outage. I have read several threads on this topic, but most of them end up with the recommendation to install a Grundfos. Since this is our home water supply, I really don't want to muck-up a working system (not to mention the cost) by replacing the pump.
One of the most informative threads is here : https://forum.solar-electric.com/discussion/352536/how-to-size-battery-and-panels-to-run-my-well-pump , however, that goes way over my head.
The specs on my pump are (not sure of the manufacturer, but Franklin does sound familiar): 3/4 HP, 230V, 1 phase, 60 Hz, 7.2A (8.3 SF Max), 3450 RPM, KVA code M, .55Kw
There is a pump control box in the pumphouse, so I assume it is a 3 wire pump.
The well is 260-270 ft. I estimate total run time per day at 3 hrs maximum. Best I can tell, the run time per fill to top off the storage tank is maybe 3-5 minutes.
I have been looking at a Magnum MS4024PAE MS-PAE Series 4000W 24VDC inverter / charger, but want to get other's experience on what they are using in a similar setup.
I have already purchased 2 100Ah 12v Battle Born batteries, but that is it so far. I am still trying to size the array, charge controller, etc. I don't mind over-engineering the system, unless it would be harmful to my well pump.
My location is central Texas.
Any input from other members that have also gone through this process would be much appreciated.
