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 12V battery. Inverter Current = 3000 ÷ 24 = 125 Amps So, a 3000W inverter on a 24V system pulls 125 amps from the battery.
A 2000w 12v pure sine wave inverter draws power based only on its load. Current (Amps) = Load Watts ÷ (Battery Voltage x Inverter Efficiency) Inverter efficiency is typically 85% (0.85). Example (12V system):
12V system: 300 ÷ 10 = 30 Amps 24V system: 300 ÷ 20 = 15 Amps Notes on wattage rating vs load: It is the actual load watts, not the inverter rating or (inverter size) that counts. A 1500 watt inverter with a 500 watt load would be 50 (25) Amps, not 150 (75) Amps.
So, the inverter draws 83.33 amps from a 12V battery. Inverter Current = 3000 ÷ 24 = 125 Amps So, a 3000W inverter on a 24V system pulls 125 amps from the battery. Inverter Current = 5000 ÷ 48 = 104.17 Amps The current drawn is approximately 104.17 amps. Understanding how much current your inverter draws is vital for several reasons:
