Powerjack inverter 24 volts 8000 watts splitphases.
The inverter transformer is over heating and turning off without any warning if fans are in automatic mode, if fans are switched on manually it won't shutdown. The other problem is that no warning are available even if battery is low it will keep on no alar and will go to 18 volts.

Although they did not look so damaged, but I changed the mosfets and the driver board.

Have you checked the "battery voltage" adjustment knob--that is, if your inverter has it?
I wouldn't be surprised if the battery voltage protection is completely disabled. Does the inverter beep several times at startup?

The only knob is the charger voltage, it doesn't beep only shutdown and then is a steady beep

Hmm. Sounding a bit like the thermal switch for the fan control isn't working? Maybe you can trace the wires and try to locate the thermal switch (it looks an awful lot like the MOSFETs actually, but it's a bimetallic thermal switch). Often covered in black goop, on top of the transformer.
Thermostat?
Thermostat?
Depending on the inverter revision, there'll either be a mechanical bimetallic thermostat (TO-220 style package) on the transformer with wires going to the fans...OR...if the fans are plugged into the control board (v11 and newer I believe) it'll be controlled by the CPU.
