Discharging standard lead-acid batteries to a low level can damage the plates due to shedding of lead sulfate from the plates. Thus, for best life, it it recommended that standard Pb-acid batteries be discharged to no more than 50% of it''s capacity, which is about 12V for a nominal 12.6V battery.
Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions
Power-to-power Summary of the storage process When discharging and charging lead-acid batteries, certain substances present in the battery (PbO 2, Pb, SO 4) are degraded while new ones are formed and vice versa. Mass is therefore converted in both directions. In this process, electrical energy is either stored in (charging) or withdrawn from the battery (discharging).
In addition to lead–acid batteries, there are other energy storage technologies which are suitable for utility-scale applications. These include other batteries (e.g. redox-flow, sodium–sulfur, zinc–bromine), electromechanical flywheels, superconducting magnetic energy storage (SMES), supercapacitors, pumped-hydroelectric (hydro) energy storage, and

The charge rate would be 1C, which is high for lead acid but not dangerous. So what am I missing? Why such a high minimum battery capacity? If the PV power is high enough and the battery is only used to form the grid (but not discharging much since the load is met by PV), then it would be good to save money on storage and instead invest it on PV.
