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?
The runtime of a 12v battery with an inverter depends on battery capacity, device power consumption, inverter efficiency, battery health, discharge depth, and environmental conditions.
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.
Here’s the magic: by connecting your 12v battery to an inverter, you unlock the potential to power various devices, bringing a touch of home comfort to your off-grid adventures. But there’s a catch – the amount of time your battery can provide power depends on several factors. That’s what we’ll explore in the next part!
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. Battery Running Time = 100Ah x 12v x 80% x 92% / 2000W = 0.4416 hours When powered by a 2000W inverter (92% efficiency), a 12V battery will last 0.4416 hours.
A 12 volt 50Ah lithium iron phosphate (LiFP04) battery with regular depth of discharge (DoD) of 80% will run a fully-loaded 1500 watt inverter for 13 minutes. The calculation incorporates typical pure sine wave inverter efficiency of 95%.
