An inverter changes 12 volts DC to 120 volts AC. If you are boon docking, and need 120 volts AC to run things that you feel essential to your camping experience, you may want an inverter. Otherwise they are unnecessary.
You cannot run high power things which are on for long times such as an air conditioner. There simply is not enough power in the battery (s) to do that. Even though you can run a microwave ovens on an inverter, for very short time periods, the microwave must be a very small one and not used much.
Your sport only has one battery I believe, and it would make the use of an inverter even more iffy.
power can be used to charge cell phones and other small items. An inverter would be handy to power a laptop, however. Televisions mostly run on 120 volts AC (some on 12 volts DC though) and would need an inverter to operate when camping away from 120 volt power.
Which brings up the point again, if you are camping with 120 volt power available an inverter is totally unnecessary.
I boondock camped for many years without an inverter and did just fine. I have an inverter now and it is handy but not necessary even now.
Hope that helps.
