The input voltage of the inverter should match the battery voltage. (For example 12v battery for 12v inverter, 24v battery for 24v inverter and 48v battery for 48v inverter Summary What Will An Inverter Run & For How Long?
As a battery chemically transforms from fully charged to discharged, it’s voltage drops from 13.5 – 10.5 volts for a 12 volt battery. As the voltage drops this affects the amount of amps required to drive a load. (Watts law: amps x volts = watts) 10.5 volts x 12.86 amps = 135 watts As such, this calculator is for sizing purposes only.
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
You would need around 24v 150Ah Lithium or 24v 300Ah Lead-acid Battery to run a 3000-watt inverter for 1 hour at its full capacity Here''s a battery size chart for any size inverter with 1 hour of load runtime Note! The input voltage of the inverter should match the battery voltage.
