Solar PV batteries: off-grid, hybrid backup and self-consumption with storage. A good 12V solar battery or 24/48 V bank accepts slow daytime panel charge, discharges slowly at night and tolerates thousands of cycles at 50% DoD without capacity loss.
Three dominant technologies: deep cycle AGM (entry-level, the most common solar panel battery for small installations), OPzS / OPzV (stationary, 20-25 years) and LiFePO4 lithium (premium, 4,000-6,000 cycles at 80% DoD).
