Let’s consider a scenario for a 24V battery bank where the lowest voltage before cut-off is 20V. Now, maximum amp draw (in amps) = (1500 Watts ÷ Inverter’s Efficiency (%)) ÷ Lowest Battery Voltage (in Volts) = (1500 watts / 95% ) / 20 V = 78.9 amps. B. 100% Efficiency
To calculate the amp draw for inverters at different voltages, you can use this formula Maximum Amp Draw (in Amps) = ( Watts ÷ Inverter’s Efficiency (%)) ÷ Lowest Battery Voltage (in Volts) Let us see an example of an inverter amp calculator for a 1500-watt inverter
Now, maximum amp draw (in amps) = (1500 Watts ÷ Inverter’s Efficiency (%)) ÷ Lowest Battery Voltage (in Volts) = (1500 watts / 95% ) / 20 V = 78.9 amps. B. 100% Efficiency In this case, we will consider a 48 V battery bank, and the lowest battery voltage before cut-off is 40 volts. The maximum current is, = (1500 watts / 100% ) / 40 = 37.5 amps
Our AC amps to DC amps conversion calculator can help you convert electric currents from an alternating current (AC) to a direct current (DC). For this, you need a DC-to-AC power inverter that takes the DC voltage a battery provides and inverts it to AC voltage so that you can run an AC-powered device.
The 20 Hour Rate means that the battery is discharged down to 10.5V over a 20 Hour Period while the total actual AH that it supplies are measured. Sometimes ratings at the 6 Hour Rate and 100 Hour Rate are also given for comparison and for different applications.
The first step to sizing a battery pack when using a DC to AC power inverter is to know your DC amp rating. Our calculator will help you determine the DC amperage as it passes through a power inverter and provides the wattage rating you are pulling so you can properly size the power inverter you need.
