Learn how many amps a 2000W inverter uses. We explain the calculations step by step for checking inverter capacity and lifespan.
Free QuoteThe 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?
To run a load of 3.2kW for 14 hours, you would need approximately 3 x 200Ah 12V batteries (assuming 85% efficiency), as 3.2kW is equivalent to 3200W, and each 12V battery can provide around 1.2kW of power for around 14 hours. How long will a 100Ah battery run a 2000w inverter? A 2000W inverter may draw around 167A from a 100Ah battery.
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
Depending on your vehicle, you can even have a 12-volt battery with a capacity of 50Ah, 60Ah, or 100Ah. Here's a fun equation to remember: if a 12-volt battery is rated at 80 Ah, it can deliver 80 amps in an hour or 40 amps in 2 hours, and so on. RELATED Klein vs. Fluke Multimeter
The maximum current drawn by a 1500-watt inverter is influenced by the following factors: Maximum Amp Draw for 85%, 95% and 100% Inverter Efficiency A. 85% Efficiency Let us consider a 12 V battery bank where the lowest battery voltage before cut-off is 10 volts. The maximum current is
