As someone that has worked on generator and was trained by generac for portables. I would like to make these comments.
Be careful when using UPS's with generators they may not play together.
A portable generator has NO field boost. Most if they sit too long will lose their magnatism and need remagnatized. This is why they need started and exercised.
Stand by unit have a field boost so even though they get exercized regularly they don't lose they magnatizm.
The bigest killer of generators is overload. The circuit breakers will not keep from overloading the generator.
Most standard generators do NOT put out clean power. Some are better than others. Be careful with electronics, they don't like dirty electric. They must run at 3600 RPM for 60 cycle output, note unloaded speed should be 3750 and under load most will to 3580 fully loaded.
An inverter generator is clean power and can be safely on electronics. They are quieter and more fuel effcient than a standard generator, but more expensive to purchase and repair.The engine speed will vary with the load, so they are usually quieter.
If you are using extension cords be sure the size meets the length and load requirements. They can kill a good generator.
Only run outdoors carbon monoxide is a killer.
