Battery & UPS
Storage Capacity Planning Calculator
Plan an idealized battery energy budget for a constant AC load.
02 / Result
Required battery capacity
Enter the design assumptions and calculate the energy budget.
Method and boundaries
Required nominal energy includes capacity margin, depth of discharge, inverter efficiency and battery state of health. Temperature, Peukert effect, BMS limits, starting peaks, power-rating sizing and compliance are not evaluated.
FAQ
What does this calculator compute?
It plans nominal battery energy for a constant AC load. The required energy includes the capacity margin, depth of discharge, inverter efficiency, and battery state of health you enter.
What inputs are required?
Enter load power, backup duration, depth of discharge, inverter efficiency, state of health, and capacity margin. Battery voltage is used when the form asks for it.
What is not evaluated?
Temperature, Peukert effect, BMS limits, starting peaks, power-rating selection, and compliance are not evaluated.
