Thanks for the many replies.
Fridge: Yup, it was the no co code. But only showed up once, I pushed mode switch then it was followed by no ac. Turned fridge on and off it worked fine. Next time was no ac when the inverter cut power to the rig due to hi voltage. This happens usually a couple of times a night as AC exceeds 130V.
I often hear a slow rumble from the fans, it was suggested that it might be a harmonic from the fans running at different speeds. My guess too.
It's running fine on AC. Outside temps right now, at 11:45 AM is 30.1 C We're in Zihuatanejo Mexico so fridge parts are very unavailable. I might be able to get the fan motors replaced or rewound and new bearings. MAYBE.
The fridge is on a slide. Gets sun in another hour or so for only two or three hours before being shaded again.
Question: will I get better cooling with the top and or lower vent covers removed?
I still haven't tackled the gas won't light (there is gas, it just won't light)likely needs a good clean. But it is very awkward to get at the igniter.
Xantrex Prosine 2.0 silly things: Twice got a AC Back Feed which I though could only happen with a wiring error. Both times it was reset by killing the post breaker AND switching the inverter off at the switch. A few minutes later turn back on and it was fine until next time.
History: I usually leave the battery charger off as I now have 420 watts of solar, though the panels start to loose the sun by early after noon. I turn the invert's battery charger on in the morning whenever the AM pre solar charging shows 12.3V--every three or four days or so.
ALSO I have left the inverter in invert mode (standby) once the heat pump is done for the day. I am beginning to wonder if the inverters internal transfer switch is a little slow and is trying to charge the batteries from it's self.
The problem has not re-occurred since I make sure the charger is OFF if the inverter is in invert mode.
The question now is leaving the inverter on to make sure the fridge keeps running without the battery recharging when the voltage falls enough, OR turn the invert function off which means turn the fridge off or the no ac will beep beep several times during the night when the voltage rises and Mr. Xantrex says I can't have it.
But the fridge takes 40 amps from the batteries when inverting. We're also running two MaxxAir fans at 2/3 speed all night. We have 4 242 AH GCs.
Did I mention that last week I spilled a 12 oz glass of water on the laptop? The keyboard says spill resistant but. . . now using a USB keyboard---designed for Mexico! :S
As DW says, more Blog Fodder.
