To get a rough estimate of your needed battery size, you can use this formula: Battery Size (kWh) = Daily Energy Usage (kWh) × Days of Autonomy × Depth of Discharge / System Efficiency Days of Autonomy: How many days you want backup power without sunlight (ex: 1–3 days). To get a rough estimate of your needed battery size, you can use this formula: Battery Size (kWh) = Daily Energy Usage (kWh) × Days of Autonomy × Depth of Discharge / System Efficiency Days of Autonomy: How many days you want backup power without sunlight (ex: 1–3 days). Battery sizing is goal-driven: Emergency backup requires 10-20 kWh, bill optimization needs 20-40 kWh, while energy independence demands 50+ kWh. Your primary use case should drive capacity decisions, not maximum theoretical needs. Usable capacity differs from total capacity: Lithium batteries. . Selecting the appropriate battery size depends on a number of factors, such as energy use, solar generation (if applicable) and export patterns. A well-sized system can keep essential appliances running, lower your utility bill and protect you from grid disruptions.
