The opposite side of the inverter has a negative & positive post that you connect to your batteries. I would recommend using at least 2 AWG wire (standard battery cables).
Ideally you want to locate any inverter, as close to your batteries as possible. I actually had this under the foot of our bed about 6 feet from the batteries. Today I have my new inverter just on the other side of the wall separating the batteries from the inside of our TT.
Next we ran an extension cord from the inverter up to our entertainment center and there we plugged in an outlet strip. We plugged in our TV, DirecTV DVR, DVD player and surround sound system, as well as some cell phone chargers. All of that is plugged into the outlet strip and will operate off of your battery bank when you turn on the inverter.
If you also run another extension cord from the male plug of the inverter into an outlet in the TT, then while you are using either a generator or shore line power, the AC power will pass through the inverter and up to the outlet strip you have plugged into the female side. This is an auto-switch and prevents you from having to switch manually. You do not have to unplug your entertainment center from the inverter and plug into the TT outlet to receive shore line AC power.
Once this is all set up. You can travel and if one day you are in the KOA using shore power, the entertainment center will work fine using the KOA campground AC power. If the next day you are at a dry camp, you can turn on the inverter to use your batteries to power the entertainment center.
Does that make it any clearer or is it still confusing?
