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):
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.
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.
The same inverter with a 1200 watt load would draw 120 (60) Amps, which would be the same amount as a 1200 watt inverter at load capacity. 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).
