I can only hear it in the washroom, but I went out to the basement area where the transfer switch is. There are two boxes there and it seems to be coming from one or the other. The transfer switch was just changed out 2 months ago. Any ideas. Thanks Macktee

Our new MH. Has a hum at the area where the house batteries are. Not too loud but I can barely here it at night sometimes in the bedroom . If I open the bay door to the batteries that's where it's coming from.The inverter / charger is right above the battery set. Just normal I'd bet.
