Christopher, Update on the Transformer Humming. Installed a new PSX-240 from Kirk and it is LOUDER than the T-240 that I took out. I have a call into the well driller to see if they have a record of the pump size or other details. When connected directly to the grid via transfer switch, still loud noise... same with battery only. I did not check the 120VAC 30 amp break in the backed up loads sub panel. All other wiring was redone as I switched the pump directly to the grid until I received the new transformer and back to the inverter again. so all the connections were redone except the 120 breaker.
