Samsung 17.5 Fridge Data Plate

We actually had the install about 10 days ago but it took me a few days to get the pics.


Dometic RM1350 original install




RF18 New fridge
The fridge




How it looks.



17.5 cuft. We are very happy.

Zero problems or issues. It’s a generic dealer supplied battery that came with the unit. Since we do not boondock, we travel from shore power to shore power. Our tow vehicle produces 357 amps while driving so the charging circuit more than compensates for what we use to run the reefer.

Awesome! Thanks.

Anyone have the surge/start amps from the Samsung 17.5, Model: RF18HFENBSR? Trying to size a battery bank and inverter combo for the RR install.

This is our setup for an newer residential 18 cu. ft. reefer system:

Are you happy with that battery? Any issues? We have T105s but would love to go with maint free.

I used a Tripplite PV1250 which is an honest 1250W continuous with a surge capacity of 2500W for an hr and 3,000W surge for 10 minutes. Yeah, it will cost about $290 but it WILL power your fridge and not break a sweat.

PV1250 also has a power save feature which turns the inverter output on when the t stat turns on the compressor and turns the invert off when the t stat is satisfied.. Saves a lot of battery capacity.. I have mine set that the fridge light bulb will trip the inverter on when the door is opened.. Newer fridges are now using LEDs so it might be difficult to get the inverter to see the fridge lights.

I have the Tripplite RV750ULHW. The only things it runs right now is the home theater equipment and a plug in front of the passenger seat. Abouut 1 eveery 3 years we carry a 5cuft B&D chest freezer. It's surge Amps are 12 amps on the data plate.

I was looking at the RV1250ULHW or the RV1512UL. I have queried Don Boyd, lead tech at Tiffin, and he has said the 1250 will work but I need to check the wiring to see if the 1512 will work. For a 2000, I will have to have some wiring changed.

I have 2 T105 and looking to go to 4 or maybe 2 12V AGM.

Your current RV750 might be a bit on the light side but might work since Tripplites do tend to have a decent surge capacity and the RV750 has 1500W (12.5A at 120V) for ten seconds.

You could look at the RV1012 which would be 1000W continuous with 2000W surge (16.6A at 120V)for ten seconds if you didn't want to spend any more money.

Or, by the PV1250 and use as a dedicated fridge inverter (PV1250 does not have built in charger or ATS like the RV versions).

You would need to verify the wire ga, going up in inverter size most likely the wiring will be a bit light and running new wire to the existing inverter/charger might be an issue.

Upsizing the RV version also will upsize the charging portion of the unit (45A charging for RV750 and 55A charging for the RV1012).

I am not an electrician so when the coach goes in to have the fridge installed, they will check the wiring and tell me the max size of the inverter I can put in without changing wires. We are gong with an inverter/charger, instead of an inverter dedicated to the fridge, only. This will take us to at least the RV1250ULHW.

MrWizard are absolutely right, we are back in Australia and it is a 240V model but surely they can also be sourced in America. It runs of a 375W inverter. Has also got a 3000W for all of FW. Ouer total usidge when running of batteries lights, water pump, tv, microwave and fridge about 70-80A from sundown to sunlight.

The startup surge is easily overcome by using a properly sized inverter, skimping on the inverter is what gets folks in trouble and overall, you WILL use much less battery since standard fridge compressor is only using 90W for about 20 minutes run time per hr..

Yup, I tried using a 600W inverter for a dorm fridge. It wouldn't take the start up surge. I'm now using a Xantrex 1000W sine inverter and the fridge operates well. 80W when in duty cycle.

FWIW, I now have a Tripplite 2000W I plan to install. I'll need some cabling but with the larger inverter I can run the whole trailer.
