The battery described may be
The battery described may be a very viable solution for home P.V. cell generated D.C. storage and inversion. The downside to of off-the-grid solar integration has been the degenerative (10%) per year storage capacity of the deep-cell storage battery; and the sensitivity of the storage bank to external temperature swings. I like the idea of a battery that will recover 100% from a full discharge. As you say, we shall see. Thanks for the informative read.
