Discover how to calculate current draw for 24V 2000W inverters – essential knowledge for solar system designers, RV owners, and off-grid enthusiasts. Learn why efficiency matters and how to avoid
DC kilowatts to amps calculation The current I in amps (A) is equal to 1000 times the power P in kilowatts (kW), divided by the voltage V in volts (V):
The current draw from a 12V or 24V battery when running an inverter depends on the actual load, not the inverter size. A quick rule is to divide watts by 10 for 12V systems or 20 for 24V systems.
Using this formula, you can estimate the current draw of your inverter based on the power requirements of your appliances and the output voltage of the inverter.
Inverters with a greater DC-to-AC conversion efficiency (90-95%) draw fewer amps, whereas inverters with a lower efficiency (70-80%) draw more
The inverter current calculation formula is a practical tool for understanding how much current an inverter will draw from its DC power source. The formula is given by:
