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):
Typically, a 12-volt car battery can support an inverter with a power range of about 150 watts to 1500 watts. Please note, however, that car batteries are not suitable for driving high power inverters for extended periods of time, which may cause damage to the battery.
The formula is based on a standard 12V battery: What is an inverter load calculation? Inverter load calculation is the process of estimating the total power (in Watts) consumed by all appliances you plan to connect to your inverter. This helps you choose an inverter and battery with sufficient capacity to power your home during an outage.
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.
The current drawn by a 1500-watt inverter for a 48 V battery bank is 37.5 amps. as per the inverter amp draw calculator.
