# Battery Pack Sizing Customization custom capacity configuration, number of parallel strings and discharge rate for sites with a defined backup autonomy and PV self-consumption target. custom capacity configuration, number of parallel strings and discharge rate for sites with a defined backup autonomy and PV self-consumption target. Capacity and module count are derived back from depth of discharge, cycle count and warranty targets, with a sizing calculation and simulation report before delivery. Sizing calculations, simulation and OEM/ODM delivery are available, with voltage level, capacity and interfaces adapted to each project.
