Update on Nova Kool RFU 8320 Refrigerator installation

Well, it has now been 7 years since I removed my original Dometic refrigerator and installed the Nova Kool RFU 8320 Refrigerator in my Escape 19 and I wanted to let everyone know that is is still running strong and giving me cold, reliable, adjustable freezer and refer temps when needed. It has a Danfoss 12volt DC refrigeration compressor which has been very responsive and reliable. My three solar panels and four 6 volt batteries have been keeping it and all the other electrical goodies going for all this time. I can go anywhere boon-docking and not worry about power.

Of course I power the refrigerator 24 hours per day at about 50% duty cycle. I have all LED lighting, a killer stereo system that gets used all the time, I run my electric coffee grinder and Mr. Coffee machine on my 2,500 watt inverter every morning before I put on my shoes, and run a CPAP machine with humidifier each night. Sometimes I run an 1,800 watt griddle for breakfast on the inverter. Evenings are often spent using electronic devices to read or browse. I am generally up to full charge by 9:30AM unless it is overcast that will delay it a few hours. If the sun doesn't come up I have a Honda 2200 propane generator that automatically shuts off when the batteries are fully charged, never more than 90 minutes but it has been used less than a dozen times.

If I had to do it again I wouldn't hesitate installing the same refrigerator and electrical upgrades in my 19. We really love our trailer!!

Steve

Thanks, Steve that is really good information. Does that Nova model fit the standard refrigerator opening on the 19 or does it have to be modified??

It required significant modification to the opening and barely fit. I felt like a surgeon opening a much larger opening that ran up against everything...but it did fit.

Steve,

Congratulations on your great experiment and sharing your results.

With our two original 6 volt batteries now being 5 years old, I'd like to know what brand of 6 volt batteries you have used, and are currently using. Where you've bought them, which type (lead acid, etc), and how long they last.

What are the signs that the batteries are nearing the end of their service life?

How often to you add water?

Bill

Thanks for the update Steve. Having adequate solar and a bigger inverter helps too!

On a side note, hasn't it been just short of 5 years since the install, not 7? Unless I was asleep for 2 years without knowing it.....

Very interested. The NovaKool RFU 8300 7.3 cu ft is 23¼" wide and the RFU 6800 6.8 cu ft is 20¼" wide. Are these powered strictly 2 way... dc and ac... no propane ?

Many models are available in DC only or DC and 120V AC. They are a compressor based design, not absorption, so no propane.

So I couldn't do one without I added 200 watts of solar to my roof and upgraded my inverter from 600 to 1200?

Steve ordered his fridge to run on 12VDC only. You wouldn't need the inverter. You would need more solar and a larger battery bank. There are smarter people than me that could tell you how much more you would need.

I believe he is only referencing the inverter to give an indication of his demands on the batteries and how quickly his solar allows them to recover under normal circumstances.

Yes, that's my assumption too. In any case, in order to run a NovaKool compressor based fridge and be able to boondock, you need more solar, and more battery.
