Yes it's very much a thing, but as mentioned it's based a LOT on what's needed for the pump. The deeper you go and the more volume you need, the larger the system needed. As you go up in size the number of companies goes down.
Look at RPS solar pumps they have many options available or grundfos pumps is another option not sure if grundfos has a battery backup you will have to research grundfos options I went with RPS for my off grid system pumping into a 5000 gallon cistern
