The serial number on the unit case should be enough.

Is the switch still there? If the switch is still there you might be able to activate it with a pencil eraser or something like that.. If you have lost the switch then you will not be able to equalizer your batteries

Officially Xantrex has the position of Note: In order to protect our intellectual property, Xantrex does not release schematics, part lists or wiring diagrams to the public. Xantrex does not sell internal parts to the public. If you need an internal part replaced, your inverter will need to be serviced by an Authorized Service Center or at the Xantrex factory.

So your options are to ship it to an authorized Xantrex repair depot, or reapair it based on electrical knowledge in general

If you decide the latter approach, you have to see if there are any IC's or other semiconductors you can identify. If they are true sine wave inverters- the wave form genesis is what counts- you will have to locate the low frequency oscillator, if it will power up and you have an oscilliscope. you can see if the waveform genesis is a square wave originally, triangle wave or a sine wave. essentially move through the traces to see where the signal goes away. your failure point will be close.

If the original waveform is sine wave, applying class A, AB or B audio amplifier principles should allow you to effect repair.

If the original waveform was square wave or triangle wave- the wave form is shaped by an LC network. Depending on what sized Capacitors and inductors are inside of the cabinet will determine where the sinewave form was achieved. If they are physically small, the waveform was shaped off the Pulse Width modulation circuit, audio amplifier principles should apply in the circuit trace and troubleshooting with the scope.

if they are physically large- the waveform is shaped at the output device(s) Usually an IGBT or power darlington..

If you are working with a modified sine wave inverter, the principles and block diagram is similar to a Class D audio amplifier or a crude AM transmitter with none of the pass filters (oversimplification perhaps)

this ought to be either enough of a start or enough of an outline for you to determine how you want to proceed.

the solar panel is just to charge your inverter,if it is charging and the inverter is on it will drain the current the solar panel is supplying to the batteries,this makes it look like it is not charging ,so i advice you to switch off you inverter when charging it,get another set of batteries connected to your solar panel then charge both, let them be separated so that the new one is not in use so that when solar is out you can switch to the other set of batteries

Yes you can. Then it would now operate on 12 volts.

If you are referring to a Trace 2412 inverter, which series is it? An SW or a DR series? In either case, if it won't accept generator power, but the AC input indicator is flashing, the problem is most likely the generator output power is off frequency or voltage. Trace inverters will only connect when the AC input is within certain limits. I'd suggest checking the frequency and voltage output of the generator. If it won't connect to shore power, check the voltage from that source. Make the voltage checks at the inverter input terminals.
