Most residential and small commercial inverters use one of the following DC input voltages: As voltage increases, the current required for the same power decreases, making high-voltage systems more efficient for high-power applications. While calculating inverter current is straightforward, other factors may affect the actual current draw:
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.
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):
Inverter Current = Power ÷ Voltage Where: If you’re working with kilowatts (kW), convert it to watts before calculation: Inverter Current = 1000 ÷ 12 = 83.33 Amps So, the inverter draws 83.33 amps from a 12V battery. Inverter Current = 3000 ÷ 24 = 125 Amps So, a 3000W inverter on a 24V system pulls 125 amps from the battery.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
To estimate the maximum battery current the inverter will require to run a piece of equipment or appliance, divide its continuous load wattage requirement by 10.
