Usage Chart: How Many Watts Do You Need?
DonRowe : Appliance power usage chart for selecting a power inverter
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):
An inverter uses a small amount of energy during the conversion process. The difference between the input power and the output power is expressed in percentages. The efficiency of modern inverters is more than 92 %. This means that a maximum of 8 % of the power consumption is used to convert battery voltage to 230V/50Hz.
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.
Yes, by knowing the inverter power and battery capacity, you can estimate how long the inverter will run on the battery under a specific load. This calculator streamlines the process of estimating the effective AC power output of an inverter, making it easier for individuals and professionals to plan and implement electrical systems efficiently.
