Inverter Usage

I've found this forum to be a wealth of information and would have been using it more had my work schedule allowed me to use my new to me '14 Cornerstone which I bought in January.

I'm leaving tomorrow morning on a short 4 day trip to Paso Robles Wine Country.

Even though I've had three other RV's, I've NEVER used the Inverter. I know how to turn it on though.

DW just filled up the fridge. I turned on Inverter, fridge working fine. I'm parked in my neighborhood so turning the auto gen on is not an option.

Question: will my batteries get run down in the eight hours from now that I'm leaving and can start the generator?

Thanks,

Butch & Dana

Maybe....maybe not. How many house batteries and what type do you have?

It should last at least 8 hours if the batteries haven't been abused.

Once on the road, the engine charging system should be charging your house batteries while also covering the fridge load.

If they are real low and you want to give them a charge from the generator, you should be able to use the boost switch, to get the generator started. That will let the inverter/charger recharge them.

Without knowing how many batteries or what size and condition they are in, you will just have to give it a try.

Butch, just my experience with the 2014 factory installed batteries. Making it 8 hours when new was a stretch. They shortened with age, but hopefully the refrigerator will be cold enough to leave and start the generator. If not, it is going to be a good test for the age of the batteries.

Checking the battery state of charge on the inverter panel every couple of hour should give a good indication of the batteries condition and how well they are holding a charge.

The batteries held on for eight hours but just barely. Had to use the aux switch to get the gen to start this morning after having Inverter on for 8 hours. The batteries appear to be original. I store the coach indoors and it's plugged in most of the time, so I think batteries are still good. Plugged in now so all is well. Thanks everyone

On my 14 Anthem, which has had two "drain the battery" episodes at Cummins and Entegra, I can go all night running the fridge off the inverter. The secret is turn EVERYTHING else off. There are lights, fans, radios, basement fridge, courtesy lights all over that pull a draw. I tried running the fridge all night once while running the floor heat, using the AH pumps, and it drained the battery too much. Maybe when I replace the batteries next year, and prevent them from being drained again, I will be able to run the AH pumps and the fridge.

All is not well. If you had to use the Aux switch to start the generator, it means that your batteries were drained flat or nearly so. This indicates that your batteries are dying. In order to achieve normal battery life, they should never be drained below 50% capacity (approx 12.0V) and yours are going well below that. In order to avoid over-depleting your batteries, your coach has an Auto Gen Start system (AGS), which will start and stop your generator automatically to prevent over-discharging the batteries which is a form of battery abuse leading to short battery life. You need to learn how to use the AGS. read your manuals as it is a little tricky to learn the AGS functions.

If its a 2014 than he will also probably have to have the EC30 from Magnum updated so that it will try to start more than once. Others will chime in here but I think there were a batch of EC30's with bad code.

He said its parked in his neighborhood which prevents him from Using the AGS to run the generator.

Seems silly not to have a fridge that runs on both electricity and propane in a RV. Who thought this was a good idea?

It could have been someone whose propane refrigerator would not get cold, or broke down, or maybe someone whose propane fridge burned his coach to the ground.

I just got a check for $300 from from a class action lawsuit settlement over Norcold's miserable propane refrigerators.

People that don't truly boondock, would be my guess. JMHO.
Happy Glamping.

X at least a 1 million. What a sorry excuse for a cooling unit. That was the #1 reason for upgrading MH's. My check from NOclod did not even cover the food we had to throw out because it spoiled in 24 hours. Never again!!! I'd go back to my old camper with an ice box, at least it worked.
