Resolved Inverter Fault Light Blinking

[NWIP]

I think the chassis batteries have a minimum voltage (11.7 comes to mind) to close a relay allowing the house batteries to charge. When you started engine to reposition coach alternator may have charged chassis batteries enough to close the relay. Glad things are charging and you have 12v lighting.

Thanks!! It was a bit nerve racking situation. And I am going to say it was my own fault for not hooking up to shore power. I installed a 50-amp connection in my garage, so when the RV was first in the driveway all was good. When I added the concrete slab in the back of the house to get it behind the privacy fence, all I had was a 110V available. But it worked fine. The 50 amp connection is in the works, it's just the trenching is slow going. In any event the last time I moved the RV back to the new slab; I did not plug in the shore power (DUH). And that is why I was "scrambling" today.

Going to be interesting where we end up tomorrow.

Switching gears on you. Generator question.
I am in the commercial construction business. When we build buildings with emergency generators, they have an "exercise" schedule the Owner's facilities folks have to maintain. ie. the generator is started at some specified interval. My whole house generator is programed to run time the first day of each month. If you do not regularly use your RV generator, does the same principal apply. Seems like it should. I had the generator professionally serviced last month. It was an appointment the previous Owner had. Probably should have asked those folks what they recommend. But did not think of it at the time.

You may have to shut off the inverter and charge the batteries with an external charger. After disconnecting the charger, once batteries are well charged, turn the inverter back on. The voltage is too low for the inverter to operate.

Someone with the same system may chime in, but that is what I would try.

Our Onan 12.5 gen, according the owners manual, is supposed to be run each month for a couple hours with a load.

Recommendation for exercising the generator monthly @ at least 50% load for 1 hour.

When you unhook from shore power, watch the house batteries to see if they drop voltage quickly. I'm concerned your batteries may be toast.

Absolutely! The concept is an idle is destructive/hard on an engine.

Electricians are charged with manually rotating motors/generators in their care on a schedule to reduce the chance of developing flat spots on the bearing. My guess is if your oil is fresh a few cranks of the starter would do the trick..

That's all I do because 50% load doesn't happen in my world very often.

I am curious. How many flashes did you get before the pause?

Just wanted to know what code it came up with.

Thanks for the tip! As of this AM the Inverter Monitor is reporting the house batteries are fully charged and is in standby mode.

During all the research I did yesterday, I did run across the cautionary information indicating batteries that have been completely discharged may not regain function.

Will keep you updated.

Thanks,
