I have a 42 gpm well with static water level between 30 and 60 feet. I will pump to a large tank next to the well, and my water needs are relatively low. An RPS 200 system is more than adequate, but I think a 1/2 hp Grundfos SQ pump is probably higher quality than whatever RPS supplies. My question is what components are required to power the Grundfos besides solar panels and inverter? This is in Central California and I'm only interested in pumping while the sun shines.
