Battery Backup Runtime Calculator vs Battery Bank Sizing Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Battery Backup Runtime Calculator
Estimate how many hours a battery backup system will run your devices during a power outage. Essential for sizing UPS systems, solar storage, and off-grid setups.
- Answers
- Backup Runtime (hours)
- Inputs
- Battery Capacity, Battery Voltage, Total Load, Inverter Efficiency, Depth of Discharge
Battery Bank Sizing Calculator
Calculate the total battery bank capacity in amp-hours (Ah) needed for off-grid solar systems or backup power, factoring in autonomy, depth of discharge, and system efficiency losses. Use this when designing or expanding a battery-based energy storage system.
- Answers
- Required Battery Capacity (Ah)
- Inputs
- Daily Energy Consumption, Days of Backup Required, System Voltage, Depth of Discharge, System Efficiency
