This battery capacity calculator helps you compare batteries. ), which means that the energy in Kilowatt-hours is calculated by multiplying the power in Kilowatts by the time in hours. 10 kwh x 1.5 days = 15 kwh of desired storage. Battery Power (kWh) = Battery Voltage (V) * Battery Capacity (Ah) / 1000. Your average DC only energy consumption is 0 Watt-hours. That would be 1040 Wh/12V = 86.7Ah battery (at 100% battery efficiency). To get to 48 volts, i strung (connected) four batteries in series. Calculate the Cost to Self-fund your own PrivatePowerGrid. Use this battery calculator to convert Ampere hour to Kilowatt hour etc. These cookies will be stored in your browser only with your consent. Or 1.2 kwh (kilowatt hours) of energy.
