Here are some possible reasons why you might be getting only 121 volts from your 2800w Yamaha inverter:

The AVR may be defective.
The inverter may be overloaded.
The inverter may not be properly connected to the battery.
The battery may be weak or dead.

To troubleshoot the problem, you can try the following:

Check the AVR to make sure it is properly connected.
Make sure the inverter is not overloaded.
Check the inverter's battery connections.
Test the battery to make sure it is fully charged.

If you are still having problems, you may need to consult a qualified electrician.

Here are some additional tips for troubleshooting inverter problems:

Make sure the inverter is turned on.
Check the inverter's input and output voltages to make sure they are within the specified range.
Check the inverter's temperature to make sure it is not overheating.
Check the inverter's fault indicators to see if there are any errors.
If you are not sure how to troubleshoot the problem, consult a qualified electrician.
