Is there a way to figure how long a 24V battery inverted to 240V will power a 1000 watt appliance?

by on March 14, 2010

Q: Is there an equation to determine what size, volts, that a battery needs to be to power a 240V appliance via an inverter and how long it will last? For example a 24V battery inverted to 240V will power a 1000W appliance for 1 hr but a 1500W appliance for 15min.
