Whatever they adjusted, keep in mind the damage was done before. On the plus side, they got 3-1/2 years and now evidently 5 years with a setup and usage that was destroying AGM batteries.
I haven't checked their site since the initial 3-1/2 year report. One thing they didn't have was intelligent information which was unavailable when they first installed that could monitor voltage and battery temperature down to the cell level. I wonder if they added that. It would have helped in the first 3-1/2 years.
