Continuing the previous example, if your inverter draws 1111 watts from a 12V battery, the current draw would be approximately 92.6 amps. Measure duration of usage: If you want to calculate the total energy consumed, multiply the power draw by the time the inverter operates.
Different inverters operate optimally at different input voltages. If the battery voltage is lower than the inverter’s rated voltage, it may draw more power to maintain the desired output. For instance, a 12V inverter operating on a 10.5V battery may increase power draw inconsistently, reducing efficiency.
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).
