CalculatorBattery runtime calculatorEstimate runtime from entered Ah capacity, nominal DC voltage, load and usable fraction.Inputs: Battery capacity, nominal voltage, load and usable fraction.Output: Runtime and usable-energy worksheet requiring product, BMS and installation review.
CalculatorBattery capacity sizing calculatorEstimate required battery capacity from entered load, target runtime, voltage and reserve.Inputs: Load, runtime target, DC system voltage and reserve allowance.Output: Required Ah and kWh worksheet that does not select or approve equipment.
CalculatorBattery charge/discharge current calculatorEstimate DC current and C-rate from entered power, voltage, efficiency and battery capacity.Inputs: Battery power, charge/discharge mode, DC voltage, efficiency and Ah capacity.Output: Current handoff for cable, fuse, BMS and product review.
CalculatorBattery fuse worksheet calculatorCompare an entered fuse rating with operating current, surge current and source criteria.Inputs: Operating current, surge current, fuse rating and source criteria.Output: Entered-data protection comparison, not fuse selection.
CalculatorBattery series-parallel voltage and capacity calculatorEstimate bank voltage, Ah and kWh from an entered series/parallel arrangement.Inputs: Cell voltage, cells per series, parallel strings, cell Ah and nominal voltage.Output: Arrangement worksheet, not product or BMS approval.
