Powering Residential Refer from Inverter

[conmoto]

I am going to install a Samsung RF 197 ACRS in our coach and want to use the 2000 watt inverter to power it on occasion. How have you folks accomplished the wire run to the refer area? I am told the current 110 lines to the Norcold are not on the inverter. For you folks that have done this I could use some advice. Thanks!

If your Knight is anything like our 2006 Diplomat it has two 110 VAC duplex outlets mounted behind the refer. Go to the outside and remove the refer vent. Look to the left and see if you can't locate two outlets. The one at the top should be marked inverter and is normally used for the ice maker. I have my Samsung plugged into that outlet and the Samsung is powered through the inverter 24/7. Note that I said powered through. As long as you have shore power or generator power the inverter is in stand by. You must make sure you leave the inverter enabled at the control panel all the time. That way as soon as you unplug from the shore power the frig will have power from the inverter. You will also note that you will not have to reset the clock on your microwave all the time.

Now the only caveat to doing this is that many outlets in the coach are powered from that single circuit of the inverter. The microwave is not and has a private circuit from the inverter. Al through I have not yet done it, I plan to put my Samsung on the private circuit and put the microwave on the public circuit. We never run the microwave from the inverter and only use it on the generator or shore power. We have installed outlets in the bath area that we connect to the 20 amp circuit on the pedestal for hair dryer and electric heater use. By doing that we have never had a problem running the Samsung from the inverter circuit that has all the outlets on it. The Samsung is a power miser and uses only about 1.5 amps after the in rush has pased from starting the compressor. I don't have an oscilloscope and current probe at home so have not measured the starting current. I suspect it is far less that the 11 amps stated in the spec.

Good luck with your install and also consider getting your Auto Gen Start updated with new software if you have one. We did on ours so it will not start the generator as long as shore power is available. We leave the Auto Gen Start on 24/7 and when the wife cuts the grass and forgets to plug the coach back in the Gen Start will start the generator and keep the batteries from going flat. The gen start is also a nice feature for our dogs when we leave them in the coach on hot days. If the campground power fails and the inside temp reaches 80 the gen will start and cool the coach back down.

Also, do a search on modified sine wave inverter vs pure sine wave inverter for your refrigerator. There have been some problems with the electronic boards that control the icemaker when using the modified sine wave inverter.

Ditto what Nodine said!! I simply plugged our 197 into the inverter circuit and it;s been running fine or a year now.

I just installed a RF217 in my MH, I also installed a small Xantrex transfer switch. This allows the frig to be powered thru the non-inverter outlet when on shore or generator power, and automatically switch to the inverter if no external power is available. This prevents overloading the inverter circuit if you are using a toaster or coffee pot or any other high load appliance.

Dennis, would it have been this switch? Xantrex Prowatt SW Inline 15 Amp Transfer Switch

Barlow46, we are thinking of installing either the Samsung or LG in our '05 Dynasty which appears to be the same as yours, with a different floorplan. Which unit did you use and did you feel replacing the Norcold 1200 was the right move?

WHIRLPOOL Model. GS2SHEXNBOO

However, I didn't replace the Norcold. This was a factory option on my 05 dynasty. This option also required a 3000w inverter and 4 additional house batteries for a total of 8 house batteries. Mine is installed on the driver's side just behind the slide out. It sits across from the kitchen slide out and is accessible with all slides in. It also has the locking door latch and this looks to be factory installed possibly by Whirlpool but not sure about that.

Thanks for the response Barlow46.

That is the switch I used, just used double back tape to stick it to the back of the refer in the old access panel area.

Hi Nodine, Wear did u get the auto gen start update new software, I have a 2006.

SRC,

Call these folks and they will take care of you. If I remember correctly the cost is $50. They tell you ship the modules to them for updating but they actually sent me new units back.

We sort of did what nodine proposes. In our coach the duplex in the fridge area was not on the inverter because otherwise the Norcold would have tried to power itself off the inverter and not propane. Our microwave had a dedicated circuit through the inverter which we never used. So down in the basement we installed a junction box and crossed the two circuits so the fridge now has a dedicated inverter circuit and the microwave does not. This has worked fine for us for 9 months with the same Samsung fridge.

Is this true for the Samsung? Why would they advertise their RF197 would run on modified sign wave if MSW can fry the electronics board?
