One of the best appliances you can start with is the Refrigerator or Freezer. Here are some reasons why: 1) They use between 300 and 800 watts so an inexpensive inverter can be used. 2) Refrigerators run quite often and use about the same amount of electricity every month 3) They are something that is typically always in use, even when you are on vacation.
You need to calculate your usage to determine what you will use. A 5 bedroom house if each room is occupied is huge. Conservatively you will use at least 10,000 - 20,000 watts per day. You will use 3,000 to 4,000 watts per day just on the fridge and freezer.
