Responder a: Mains frequency is too lowZamolxe , Sir Every notes you've mentioned is correct , I know roughly that the efficiency will drop by 20% since using 45Hz frequency , but they're long hours of using diesel generators , all I wanted from APC , is passing this 45 Hz as it is to my loads , but APC refuses this , since it's out of (clean power) criteria !. But finally I succeeded to (Trick) the processor to deal with such low frequency by using external standard 50Hz function generator , you could watch my youtube channel to find how !. https://www.youtube.com/watch?v=GNEDBTa2...
