So, battery running time for a 12V battery with a 3000W inverter (94% efficiency) is 0.3008 hours. Battery Running Time = 100Ah x 12v x 80% x 95% / 5000W = 0.1824 hours With a 5000W inverter (95% efficiency), a 12V battery will run for 0.1824 hours. Battery running time for a 12V battery with a 5000W inverter (95% efficiency) is 0.1824 hours.
Many people make the mistake of connecting a 3000W inverter to a single 12V 100Ah battery. This setup cannot handle the load, which leads to overheating and early battery failure. To avoid this, you need to understand two key factors: battery voltage and capacity. The higher the battery voltage, the more power your inverter can safely handle.
As a simple rule, to calculate how long a 12v deep-cycle battery will last with an inverter multiply battery amp-hours (Ah) by 12 to find watt-hours, and divide by the load watts to find run time hours. Finally, multiply run time hours by 95% to account for inverter losses. Introduction to Solar Power Battery Inverters – What Do Inverters Do?
Let’s say you have a 300Ah battery. 300 ÷ 250 = 1.2 hours. Drawing 3000 watts from a 300Ah battery will run for a maximum of 1.2 hours. If you reduce your power draw to 2000 watts, you would increase your runtime to nearly 2 hours! Remember, a 3000W inverter won’t always draw maximum power, it depends what appliances you are running.
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.
