The size of the inverter versus your needs and or future needs is important. Want to run a microwave or coffee pot then you are going to need a larger inverter and probably batteries. Some inverters canbe hard wired some can't. Some 3,000 watt inverters have two 120v outlets 1500w each. Mr. Coffee 8c doesn't like 1500 watts.
Converters charge your batteries when your generator is running.
