Generator/ storm question

We lost electric power Tuesday early afternoon. I am currently running my household refrigerator and one fan on a portable generator.

I am thinking of sleeping in my REV tonight and running the Onan 2800 generator for the air conditioning and my CPAP. Will I also be able to run my household refrigerator from the REV generator?

If the name Onan 2800 implies it is 2800w then likely no.

The A/C will use most of that to start the compressor once it starts to cycle.

Add in the converter to keep the 12v system working and that doesn't leave much (if any for your household refrigerator.

Why not turn the fridge off overnight?
Leave it on the current genny until bedtime and then don't open it. It will stay cold an easy 6-7 hours. Ours does.

My cpap operates on 12 volts.

Turning on the inverter For The cpap uses power. Wastes 30-40%. It is dc/ac/dc.

Freeze bottles of water for drinking and Put them in the fridge. Turn the fridge off at nights.

No inverter.

So you're one of the 'millions left without power' due to the hurricane? I hope everything else is ok.

That generator is pretty small so the advice about ice in the home fridge is good advice. Not only is the generator small, but the gas tank in the REV is pretty small too and that generator runs on gas. I've never tested it to see how quickly it will run out of gas.

Hope you're able to get a good nights sleep.

Because a couple of hours into the outage I was surprised to notice the fridge temp was in the 40ís.

Thanks.

It sips gas, I am thinking about a half gallon an hour. I donít use it often other than to exercise it or for a couple of hours for the AC.

Thanks for the good thoughts.

Good news is that the electricity was restored about midnight.

Glad your electric is back, we are still out with estimated restoration

Ouch, that stinks. Hopefully your electric company is overestimating the time for restoration.

My shed was flooded again, mostly due to railroad construction in the area. They clear cut wooded areas twice and changed the embankment slopes. A bunch of homes affected again.

I hope you get back to normal again. Let me know if there is anything I can do to help or bring to you. That would be a good excuse to show my wife your home. IF you are accepting visitors.

Be Well.

Donít make my mistake and down size your home refrigerator. Doesnít take much to fill it up.

I have the 12 volt adapter cord to run the CPAP off of the battery power. I went through the inverter once but that didnít last all night.

This RV generator has powered my household fridge, some lights and phone chargers in previous outages. I was wondering if I could run the RV AC at the same time. I doubted that but decided to put the question out there.

Thanks.
