Shore versus battery

When shore power is connected to my T@B: My electrical outlets are receiving power and my A/C is running strong and cooling nicely.
After shore power is disconnected and I am running on the battery: My electrical outlets are not receiving power and the A/C is very weak. All of the fuses are good.
I have no idea what is wrong and how to correct this problem.

    One other thing: I installed a new battery a couple of days ago.

    Your profile pic shows an older T@b 320. Unless it has been modified with an inverter and additional battery capacity the 120V outlets and the A/C do not work without shore power.

    @Red_Rover your t@b uses 2 types of power, 110/120 V (shore power) and 12 V (battery power). All outlets are 110/120 V. When you are disconnected from shore power, your 110 outlets and appliances are not receiving any power. Your t@b is wired that way. Nothing is wrong with your trailer or its systems. 

    320 t@bs have not come with an inverter, but the new lithium pkg may now have an inverter which converts battery power 12 V to shore power 110 V. The t@b 400 have an inverter which when switched on can power one or several outlets. The  appliances such as microwave and A/C are not  wired to run on battery power except for the current model year with the lithium pkg as those appliances are very power hungry and cannot operate without a large enough inverter to change (invert) battery power into shore power and will not sustain those appliances for long periods of time because you simply do not have a large enough long lasting power  source to do so.

    Experts more familiar with individual model year variations may be better able to explain what your t@b is wired for or what options you have available.

    The new trailers with the lithium battery installs will be pretty confusing until owners get the real hang of what a lithium setup can do, and what it cannot.  Tell us more about what battery setup you have, and if it has the inverter, etc.

    I have a 2017 320 and thank you so much!! It makes perfect sense 110v versus 12v.
