What is the current of the 12v inverter

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. 33 amps from a. 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. For more accuracy, divide the load by the actual battery voltage and adjust for inverter efficiency. To find the proper wire and fuse (or circuit breaker) sizes for your 3000 Watt inverter, you'll need to calculate the maximum amp draw of the inverter. This maximum amp draw will generally depend on 2 factors: The efficiency of your inverter. With just a few input values, users can calculate the current to properly size batteries, cables, and safety equipment. Understanding inverter specifications helps optimize power consumption and battery voltage for better performance.
