Some generators don't produce a clean frequency of power, so the variation can cause some problems with some equipment. something with a voltage-regulated DC power supply like a laptop can cover for quite a lot of that. If you are unsure, a power-conditioner is cheap insurance, some can be wired right into the house, handy if your local mains power is a bit flaky. And you might get an improvement on your home insurance.
It really depends on the generator. Some the no-nos are from old generators that didn't have auto throttles, or good voltage/frequncy regulation. Fridges run intermittently, so that can cause problems for some old gennies, but the solution to that problem is to just keep the thing running at full throttle, so it can always give the needed power. You can also check your appliance tolerances for power input, should be a sticker on it, or contact the MFg. As long as you have good over-volt protection on the genny, at worst your TV or whatever might not like the power, and not turn on. But I don't think that is going to cause any damage. Im not an engineer though, just run a couple rock shows off of gennies, but then the you'd expect the big three-phase monsters to be reliable.

The output voltage of the generator is an important factor in the power generation efficiency of the generator. However, many people encounter the unstable voltage of the small diesel generator during the use of the generator, which has a great impact on the normal operation of the generator. For some manufacturers who use the economic efficiency of diesel generators, the economic loss caused by unstable generator voltage is very huge.

The instability of the output voltage of a small diesel generator can be caused by several reasons:
1. The generator is overloaded, and the large-scale electrical appliances on the load frequently start to cause large fluctuations in voltage.
2. Because the generator itself has bad factors, the excitation voltage is unstable or the carbon brush is in poor contact. Specifically, the excitation winding and the excitation power components can be inspected, including rectifier diodes and Thyristors and other RC components. Adjustable potentiometers are also often used. If contact is not good, care should be taken.
3. It may be due to the unstable speed regulation of the diesel engine. It automatically adjusts the output power according to the light weight of the load. The high-pressure oil pump supplies more oil and stabilizes the speed, and should be repaired or maintained.
The wiring of the wiring is loose, and it is necessary to check the connection parts of the small diesel generator set and repair it. The control panel voltage-current selection switch fails and the diesel generator set replaces the switch. The control panel voltage adjustment resistor fails and the Voltage Regulator resistor is replaced. The voltmeter fails and the voltmeter is changed. If the regulator is defective or the regulator is not adjusted, check the regulator. The diesel generator is running too much vibration and check the diesel generator set shock absorbers. The engine speed is unstable and the engine fuel system parts are adjusted or replaced to stabilize the speed.
