2019 32sa with 2 door residential refer size

[Oregon Rick]

I have a 2 door residential refrigerator/ Freezer and I don’t know the cubic feet of it. I also would like to know if I have fully charged batteries, (4 - 6 volt) how long will they run the refrigerator if not plugged in to power?
Thanks… Rick

Somewhere in your refrigerator there should be a tag/label with at least a model number and serial number and other information. On our Maytag, the tag/label is on the top left of the refrigerator just inside the door. Size may be shown on label. If not, Google model number. We can easily go overnight on our 6 house batteries. Typically run generator 2-3 hrs before bedtime and 2-3 hours in morning. Obviously, lots of variables and your results will vary.

How long will it run is a common question. The answer depends on the condition of the batteries and what other loads you have.

Assuming you don't have a battery monitor you can track your battery state by using a battery state of charge table. If you start with a full charge and then check the voltage say 8 hours later and look up the state of charge you can figure out how long before your batteries drain.

With lead acid batteries they will last longest if you don't drop bellow 50% State Of Charge(SOC) which is about 12 volts. You can go down to 30% with some reduction of life, but it's not too extreme.

Another issue with lead acid batteries is you need to fully charge them fairly often, but unfortunately the last 20% has to be charged fairly slowly so it requires a long generator time.

When boondocking you definitely need to track and understand your state of charge,

I recently bought a 2015 32SA. We just brought it home from a 2 month stay at a local RV spot. With the coach parked on the street, no 120v, our fridge drained the batteries in less than a day. We have 4 new interstate batteries. We had it sitting on the street for 3 days total. I had to run the generator every day for a couple hours.

I bought all the solar equipment, but just need to install it.

I have the 2021 32SA, w/ the solar option (2 panels... I think it's 200watts, but might be 400watts... I don't recall).

From what I've seen, it will run for days.. had it parked in the driveway for 4 days with the fridge running, going in and out, loading stuff in an out, lights occasionally running, and the solar seamed to keep the batteries fully charged, even with the fridge going.
