I talked to the tech at vector and he was less than enthousiastic but did offer to replace it. he said I should use a power filter on my genset
but was unable to tell me any thing obout one. as you guys know I am electricaly illiterate. so can any body give me some guidance? JJ, Sean, or any of you other electrical geniuses. |

Ron,
My opinion is the 'tech' was trying to justify an unexplainable failure. For completness we should know, what generator do you have and what product from Vector quit. If you have a 'Quiet Diesel' or another variable speed generator then there may be some waveform distortion and harmonics that a filter could remove but even these should do no damage as the output should be as good as any power pole. If, on the other hand, you have an ordinary constant speed generator the waveform is usually quite good with more distortion (but still less than 3%THD) at full load. Severe distortion, like from a 'modified sine wave inverter, way cause overheating in motors and electronics that use transformers (like microwaves) but generators produce power as good as the utility grid without filters.
Hope this helps.
Regards

Ron,
I agree with Jerry for the most part.
The one additional note I will add, and I think this got posted in the other thread, is that you should ensure that the generator is stable before connecting any "sensitive" loads, and the Vecter may be "sensitive."
The generator will be putting out low voltage and low frequency while it is cranking and for a short period of time thereafter. Furthermore, capacitive and inductive devices on the output can exacerbate the issues during startup. For this reason, and to ensure that the genny doesn't "bog down" under immediate load, I recommend that you allow the generator to stabilize for anywhere from 20 to 60 seconds before connecting any load to it at all.
Many Automatic Transfer Switches (ATS) have this delay capability built-in, and some generators do as well. If you have neither of these, you can either manually disconnect your loads before you start the genny and connect them again after a suitable wait, or you can add a delay timer setup to do this automatically.
It is possible (but not likely) that the charger was damaged during generator start-up. If it was, a filter is not the answer, but a delay would fix it.
