Technical FAQs 4

How long will a 12V battery last with an inverter?

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?

How long can a 12 volt battery run a 1500 watt inverter?

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%.

How do you calculate inverter usage time?

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.

How does the inverter energy calculator work?

Energy is calculated in joules, based on the power consumption (in watts) and duration of usage (in minutes). This calculation helps homeowners, solar energy users, electricians, and technicians better understand energy needs and optimize battery and power configurations. Using the Inverter Energy Calculator is very simple.
