Diesel generators always burn things when generating electricity! ! !

I really want to help you, but it also completely solves the problem. I can only analyze it. For reference. 1, the electricity generated by the generator is unstable alternating current. See if you have a voltage stabilizing circuit. Is the frequency 50HZ, or is it too high for electrical appliances? I calculated the power of your appliances, but none of them are large. 6KW at most. The conclusion is that the voltage is 300V, burner. The frequency is not 50HZ. Oh, and pay attention to whether the three-phase rated voltage of air conditioner is 380 volts or 220 volts. It is judged that there may be a missing phase.
