Battery only power

Just bought the delta 262rb. Sitting in my driveway. It is not connected to any power source other than its own battery.
so how can I turn the power on? I have pressed many buttons and I have gone to the pass thru and turned the red key for battery disconnect both ways.

nothing

It’s my understanding that the refrigerator will not run off of solar even with a 100 Ah battery. Is that true ?

The simple answer is not true! The underlying question is how long will it run based on the charge sources that are replenishing the battery.

It is a 12 volt device and will run until the voltage drops below the low voltage cut off.
Remember that the compressor cycles on and off as needed so the amp draw isn‘t consistent .
We have towed as much as 11 hours with our 310 RL and a single solar panel, and our trucks charge line as the only input sources to a less than 100 ah battery and had no issues.

The 10 cu ft DC uses about 80-90 ahs of 12v battery per day, so it "should" run off of a 100 AH battery. Truthfully, it depends greatly on what type of 100ah battery that you have. If you are using a 100 ah lead acid battery you should only draw it down 50% or 50 ahs otherwise you will risk ruining that battery. If you are talking about Lithium Iron Phosphate batteries, these can be almost taken down zero, so one of these should definitely be able to run the frig for a day.

We have 2 100 ah lithium batteries and a 400 watt solar panel on our trailer and we have not had any issues running the frig. If it is sunny, the batteries are usually back up to full charge by 11 am.
 
The 400 watt panel keeps our 100AH lithium battery fully charged while we are in direct sunlight. I’m very impressed with it, we didn’t even have to use our generator the last time we went boondocking.

We have 2 100amp lithium batteries and a 320 watt solar panel and can boondock for 3 days with good sunshine running everything, dc fridge, (cpap at night) but 4th day need to fire up generator for couple hrs. Works well and havn't been able to justify more solar and more batteries to become totally independant as only really boondock couple times a year for 3-5 days and carry a 2000 watt genset for emergencys.
