over size generator alternator for VFD load???
over size generator alternator for VFD load???
(OP)
guys, when using generator as back up power. is it critical to oversize the alternator in the generator to run VFDs??? if so why??? I spoke to an VFD tech, and he mention about over size the generator and its got something to do with the high power source impedance of the generator being 6 to 8 times higher than the Utility ... does anyone knows what he mean??
