Battery Bank Sizing Calculator vs HVAC Duct 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 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
HVAC Duct Sizing Calculator
Calculate the required diameter or dimensions of HVAC ducts based on air flow rate and design velocity. Use this when designing ventilation systems to balance air delivery with noise and pressure loss constraints.
- Answers
- Duct Dimension (inches)
- Inputs
- Air Flow Rate, Design Air Velocity, Duct Shape, Aspect Ratio (for rectangular)
