Technical FAQs 4

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):

How much power does a 1500 watt inverter draw?

A 1500 watt inverter with a 500 watt load would be 50 (25) Amps, not 150 (75) Amps. 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.

How do I choose a 12V inverter?

Inverters are key in 12V power systems, changing low-voltage DC to the AC needed by many devices. When picking the right 12v inverters, think about efficiency and energy use. This ensures your system works well and uses energy wisely. Choosing an inverter means looking at your power needs closely.
