Hi all, The country where I live, electricity outages are a part of life, so to compensate for it I have a small 2.2kW 220V AC generator in my house. The problem with it is that I've heard and found out for myself that its output is unfit for running electronics. Testing with a voltmeter, the output is a consistent 220V, however, whenever I turn on my PC on it the power supply makes a weird buzzing noise. Also, I have a UPS w/ surge protector that doesn't even go on charge mode when plugged in with the generator on i.e. it doesn't consider the output suitable enough. Many laptop repairers and computer technicians have also warned me not to charge laptops from small, single phase generators. So anyone have any idea what the problem might be, and more importantly any inexpensive way to get around it? Thanks in advance.
