To calculate the DC current draw from an inverter, use the following formula: Inverter Current = Power ÷ Voltage Where: If you're working with kilowatts (kW), convert it to watts before calculation: Inverter Current = 1000 ÷ 12 = 83. 33 Amps So, the inverter draws 83. It is useful for home users, installers, engineers, and anyone planning an inverter system. By understanding current values, you can choose safer cables, protect the system. . 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. 85% Efficiency Let us consider a 12 V battery bank where the lowest battery voltage before cut-off is 10 volts. Thus, Current = 500W / 12V = approximately 41.
