I am lost . I have a Residential Fridge INVERTER LG 1000 or that is what is on the door. I just switched from Motorhome to new Pincrest 5th wheel.

I have never had this type of Fridge . Can someone explain.. is the inverter built in ? does it work off the other inverter or alone. ..
How long will it last I have one 12 volt batter.y I will soon be upgrading and adding solar. What do I need to know. I have budget of $2,500-$3,000.00
I guess this is two questions or three. I alway had propose, gas and electric Fridges . They seem easier to use overall and more versatile to me.

I think I updated my signature 2020 Vanleigh Pinecrest 2020 2500 Dodge Ram

Two trips in not sure if we made the right decision.

Short answer. It is a residential Fridge, needs 120 VAC to run.

nice refrigertor.

no, you need an external inverter to produce 120 vac power for the refrigerator.

expect it to run perhaps an hour or two with one battery.

as for what you need, it depends on where you will be. if hooked up to shore power all the time you should be fine. if you want to live off the grid, more battery capacity.

Well, THAT was a pretty useless video to answer any of the OP's questions . . .

It will run more then a few hours on one battery.

Even if it draws 20 amps at 12 volts ( thru the inverter ), it won't run all of the time, maybe 1/2 the time.

So, now we have a 10 AH draw. 1 cheap, 75 AH battery, will run it for 4 to 5 hours without any charging source. A lousy charging line from the truck could double that.

You will love the residential fridge. Bigger. Cools fast. Cheaper to replace. No fire risk. We just have one inverter that does it all. Once you install the solar you should be good even for boondocking. Use your genny when needed.

I believe that the “inverter” means the compressor can run at variable speeds, in theory being more efficient.

The number you provided I believe is the water filter.

The model number should look something like this LFXS28566M. This is a refrigerator I bought for the house recently, this is a +27 cu ft refrigerator. Energy guide says 724KW per year so it would use 1.98 kw per day.

So not knowing exactly what model you have it will be hard to estimate.

The refrigerator will need 120 volt so you will have to run an inverter all the time.
I recently installed a Samsung RF18 (it uses 594KW per year or 1.6kw per day) and after I was done did a test. I have 4 batteries, they are not new but in decent shape. Hot day, nothing else running, the refrigerator was empty so this would be worse case scenario for me. I also have 325 watt of solar. I was able to run the refrigerator for 8 hours depleting my batteries to 50%.

I battery will not last long, maybe 2-3 hours. I've looked at adding more solar and ball park is you need ~1200 watt to improve running time for residential refrigerator. Also need battery capacity for this to work.

Glad you liked it. It showed that the 'inverter' for Lg was not a built in voltage adapter.

I give up and really do not like the residential fridge. I now have 4 lithiums 4 solar panels and one portable . I am always worried that I do not have enough sun power and the food will go bad. With propane / etc I never had to worry.
I spent $1,500.00 for a tec to tell me I have no other drain the than fridge.
I don't understand why they are so popular. The " salesman" said it will last 3 or 4 days . It will last 3 or 4 hours on the one battery that came with the unit.
I should have researched better.
Just two of us traveling 99% of the time so we do not need the space either.

Buy a 1000 watt inverter/generator.

If the batteries get low run the generator for a few hours.

Even a gas fridge needs 12 volt battery power to operate. Not as much, but it will shut down when its gone.
