Thank you, Kirk, Scott and Bob.
I had suspected that the noise was coming from the refrigerator because when I opened the benches, it wasn't any louder and seemed to not be coming from anything in there, but from the general direction of the refrigerator. Noise has now stopped.
Disconnected 120 and lights work. The odd thing is that the battery tester is still blank. I associated that with the two beeps but have not had occasion lately to use it, having been plugged in for several weeks. Guess the tester must have happened to go bad. Solar is still at 13.4.
