Medium and large inverters generally draw between 1000 to 5000 watts from a battery. This range reflects their power consumption when converting DC (direct current) electricity from a battery to usable AC (alternating current) electricity for devices. For medium inverters, typical power draws range from 1000 to 3000 watts.
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):
You can find No Load Current mentioned on the specification sheet as no load current draw (amps) or as no-load power (watts). Now to determine how much power your inverter is drawing without any load, multiply the battery voltage by the inverter no load current draw rating. For example, Battery voltage = 1000 watts Inverter = 24V
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 (typically 85%). This ensures you can correctly estimate battery drain and size your system safely.
