How many Watts should a 12V inverter use?

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.

How much power does a 12V inverter draw?

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):

What are the different solar inverter sizes?

Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly. During our research, we discovered that most inverters range in size from 300 watts up to over 3000 watts. In this article, we guide you through the different inverter sizes.

How much power does an inverter use?

The more modern the inverter, the more power you save. A 90% efficient inverter means it requires 10% more power than what its load requires. If you run a 300 watt load for instance, the inverter will need 330 watts. With larger inverters the drain could be up to 2 amps even a load.
