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 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.
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%.
To calculate the usage time of an inverter, multiply the battery capacity by 12 (to convert Ah to Wh assuming a 12V battery), then multiply by the inverter efficiency, and finally divide by the load power. What is Inverter Usage Time? Inverter usage time refers to the duration an inverter can supply power to a load before the battery is depleted.
