12V apparently out

[float5]

I am hearing two long beeps every few minutes. Battery charge tester has a blank screen when plugged into 12V.

120 working fine. Plugged in at pedestal. EMS has no errors so refrigerator and all on 110 working. Electrical panel no lights.

Master switch on.

Solar had 14.4, now a half hour later 13.4. Had five short blinking lights but now not blinking.

Long beeps still going on. Opened benches and can't tell where they are coming from.

If I put in a phone into USB, it charges though.

Does anybody know about the two long beeps?

Are your interior lights still working?

My first guess is the fridge door is not shut tight enough, or else your smoke detector battery is getting low.

Your solar charges at 14.4 V for an hour in the morning, then goes back to 13.7, so it might not be the problem.

Did not happen to try the lights. Microwave and refrigerator working and refrigerator not blinking.

Not there now. The solar went to 13.4 and then stayed there a while so hope that is still where it is.

I agree with Kirk, most likely the refrigerator door alarm. The display will not blink when the door alarm beeps. I have had this happen on a couple of occasions and it still takes me by surprise. Scott

Disconnect from the 110AC and see if the lights still work. If yes, 12vdc okay.

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.
