I just finished installing a full solar system [600 watt] with inverter in my Aviator and went through three inverters till I got it right. What ever you THINK you need in power, triple it!! Refrigerators, microwaves and A/C units take a big upfront surge of power to get them started. Don't get caught short.
Also keep in mind the inverter will use MANY AMPS, VERY FAST out of your batts. Unless you have a bank of 4 or more 115 ahr batts, you won't last long with high draw appliances. If you will only use them for short times, the batts will be OK at three or more. Make sure the cables connecting the batts and inverter are really big [I used 3/0] Wait till you find out how much THOSE cost!!
Good Luck! Sit down and figure out what you will need ahead of time and save yourself a lot of time, trouble and expense.
One more thing. If you are using a mod sine wave inverter, you will need a voltage tester that measures RMS volts or it will look like you are short 20-30 vac. Appliances do not like mod sine wave units. Spend the money and go pure sine wave. You won't regret it.
