The biggest difference between inverter and non-inverter AC is the fact that the motor of the inverter compressor has a variable speed. The speed of the non-invertor compressor is fixed. This means that it operates either at full or minimum speed. A censor in the invertor adjusts the power according to the temperature in the room, lowering the electrical consumption and saving energy.

Due to the sophisticated operational method of the invertor, its compressor does not work at its full capacity all the time. When the speed is lower, the needed energy is lower too and you pay less money for electricity.
As the compressor motor of the inverter air conditioner does not turn on and off all the time, but keeps working at low power, the operation is more quite.
The technology of the inverters not only makes cooling and heating more efficient, but it also makes the AC's life longer.
Last but not least, the inverter AC is able to cool or heat your room faster than the non-inverter. This is due to the fact that in the beginning of the process, the inverter uses more power than the non-inverter and diminish the power when it gets close to the desired temperature.

although it is possible to do separately most times the transfer switch is internal to the inverter , and the fact you mention that inverter is not charging batteries tells me your fault lay in the inverter all or part of it is not working , look at it carefully these have sometimes two reset breakers on there cases

Please understand that the generator produces power from fuel with an engine wheras the invertor is one which genrerates power from a stored battery using the principle of frequency switching a DC source to induct and produce AC.
Now you can have an uninterupted power supply setting with the invertor backed up by the generator so that when the battery voltage goes down you can start and charge the invertor and also supply the extra energy .
the ratings of both must also be considered.

You better buy a multi turn potentiometer about 4,7 - 5,1 kOhm.

Connect its ends to "+10 V" and "ACM". The Slider connect to "AVI".

The multi turn pot can make small steps of adjustment.

Hope that it will help.

Checking AC Output
1. After the battery voltage and connections have been checked, disconnect the inverter.s AC output wires from
the power distribution system and connect a light to the AC output of the inverter/charger.
2. Disconnect the remote panel to eliminate it as a possible problem.
3. Turn the inverter ON using the power switch on the front panel of the inverter. The 100-watt light should
illuminate. Measure the voltage at the AC output wires using the multimeter. The reading should be 114.126
VAC or approximately 230 VAC if the unit is an international model. If the light does not illuminate, there is
a problem with the inverter. Contact Xantrex technical support.

check the system but you may have to turn off the batteries
the inverter is charging the batteries but when mains power fails , the batteries will be discharging back through the inverter that is dc converted back to ac
if you power on a genset and the ac is not phased correctly, what you describe will happen--- inverter ac from the batteries against genset ac to the inverter-
If you had mains power on then it would dead stop the genset because of the out of phase situation
it all has to do with the 2 wave patterns for ac current from each unit being in harmony and not working against each other

check if the fuses are broken the replace them with the correct type, and check if the is any burnt part

hi i have trace sw5548 and the power keep turning off and i have to go in P G and E power, why would it keep turning off thanks

Inverters normaly have inbuilt protection built into them check for reset button/switch.
