ENERGY STORAGE CALCULATOR Battery Storage Calculator for kWh, Autonomy and Backup Sizing Need to know how much battery storage a home, office, laboratory, telecom site or small facility needs during an outage? This free battery storage calculator converts load power and backup time into a practical battery capacity estimate, while accounting for depth of discharge, system efficiency, reserve margin and DC voltage. Quick answer: battery backup sizing starts with the energy your loads need during the outage. Multiply the average load by the required autonomy hours, then divide by the fraction of the battery you can safely use. Real designs also need efficiency losses, reserve capacity, peak-power checks, temperature effects, battery chemistry, inverter limits and manufacturer data.
