I plan to do a LOT more research before opening my wallet. I don't need to have anything installed until late November.
Don-thanks for the link it fits well with my line of thinking which provides a level of comfort.
While I was in Quartzsite I stopped in to a couple of solar installers to discuss lithium batteries. One shop has no plans to handle them till the price drops a lot. The other shop carries Relion batteries. While I was talking to them 2 customers came in and bought Li. They were selling the 100 Ah for $1250 and the 300 Ah for $3100. The big one is in a 8D case.
