Finally buying a strong inverter. How many batteries to buy?

Cheryl,

You can successfully run an air conditioner on a 2k genny, if you add a microair easy start kit at temperatures up to 100 F.

My generator will shortly live on a rack on the front of my class C. It would require someone with a cut off wheel or cutting torch to make it disappear.

Most of us have two inverters. A small 300 watt PSW for low loads such as laptops and TV, and a larger one for things such as a coffee pot or reheating in a microwave.
