I am an infrequent (3/year) designer/installer of grid-tied battery back up systems. I really like the SunXtender battery line. We can get them for a good price (contact me off line) here in Los Angeles.
With that, I cannot vouch for cycling them 1,200 times to 80% DoD. That seems a bit severe. I have a graph of #/discharges vs. DoD for thee batteries. I will try to dig it up and make it available. - Peter Peter T.
