Pricing Introduction Inverters take battery energy and make it into household electricity. To find the size of the inverter you need, find the largest AC appliance you want to run.
All inverters mimic the electricity that comes from the electric company.
There are two types, modified and pure. Modified does a very good job at running most appliances. Pure sine wave inverters do it even better. All the outlets are automatically electrified with household or 120 volt electricity. Small inverters plug into optional DC outlets.
