Res. Fridge and inverter wiring confirmation plz

[terry735001]

keep in mind if you have a MD inverter running a home series frig can start a fire as well

some low end MD inverter well make the unit run hotter and / not run at all and the relay / or pump motor can start a fire ..seen it..

if you have a good SW inverter then your ok but keep in mine the Samsung 197 series well pull some amps

make use you are not pushing you max amps out on the inverter when every thing is running that you want to run why going down the road

make use you are not pushing you max amps out on the inverter when every thing is running that you want to run why going down the road

Just want to understand what you're saying

The Samsung RF197 draws ~100 watts on the average but, according to Samsung an inverter supplying it has to be capable of providing a maximum load of ~11 A. The typical 2kW inverter/charger used in many MH's can easily handle this load.

So what's a MD and SW inverter

[Dutch Star Don]

"loulong"......You answered your own question....... opening and closing CONTACTS, not a solid connection!

[Happycarz]

MD = Modified sine wave inverter
SW = Pure sine wave inverter

At leas,t that is how I interpreted it.

The world has been using relay technology in power switching for many many years without "consuming" them. Where's the problem?

its not the watt its more the amps 11 amps AC is all most 33 amp 12v DC after the inverter

add kick in load and your max amps get up there add any thing else in the RV and you get some wires hot for a min

Md inverter are for running motors but even some low cost motors well not run on a MD inverter like a 20$ box fan if it runs you can hear a bad humm from the motor

this humm in a bigger motor makes heat

now days most high end frigs have so many high tech items installed in them to make them look cool all so dont like MD inverters

add all this up .. with a guy that is not sure what a SW / Md inverter is and the % go up that a bad day can come

>> not picking on you OP << sorry

we are here to help this guy and help him get to know / help

yeah it rear that all this well add up but i am the guy that all ways say the things not said some times that should to help

PS the RV on the other side of the guy walking had a home frig in it that started a fire its all so on the right side of the airstream

what looked like happen there was most newer RV run one wire for ac power up the passenger side of the RV your stock frig only pulls 3 amps
this frig look like it pulled to much / like the pump lock up going down the road and wiring got hot

this is the you pull it junk yard for RVs i go to all the time and pulled my RV out of there is all ways about 40 RVs in here and wish i could add more pics all them

sorry OP just seen what you said

when i looked up really fast on google the frig you are talking of looks like it pulls more then 2 amps so i am not sure there


some else said it better but here a new way to look at it

MD inverter is a low cost inverter say bad gas for a car
SW inverter is cleaner then the power you get at home 100% the truth


so a MD inverter is like running your car on back gas it well run but for how long and how well

now truth be told i dont know what type of inverter you have

but as i said i am the guy to go hay in the back ground and say what about this did you look in to this did you make sure of this ..


all in all in the net you well find and get info saying yes and no on any thing
i just give you some thing to think about and look up so you know and have a good frame of mind on how to safely make your moods

The 11A draw only lasts for a second or two when the compressor starts. We are running our RF197 on a 1000W inverter. Our inverter has a surge capacity of 1800W, which is enough to handle the startup of the compressor.

My MH has a 2K Watt Square Wave Inverter. One of the reasons I explicitly selected the Samsung 197 series is that Samsung has stated their support for square wave 110V input. That and many others have been successfully using this fridge with my type of setup.

I understand the difference between a square wave and pure sine wave inverter, which led me to choose this fridge. Thanks all

akeyzoo........I'm a little anal and I wanted a separate inverter for my Samsung. As I said before, I don't like having my inverter on all the time because all of my TV electronics and several other items are on the inverter system and I didn't want to keep turning things on and off when ever I was driving.

My coach has the Magnum 2000 watt MSW inverter. I added another Magnum 600 watt MSW inverter that had a pass thru switch. I've put 8000 miles on the coach running the refer off of the smaller inverter. So......it doesn't take much to keep the Samsungs running. My understanding is that Samsung converts 110v to 12 volts to run their refer and that's why they are so compatible. Maybe Samsung will realize what a gold mine they have and just make a 12 volt model.

Usually a Modified Sine Wave inverter is MSW.
A Pure Sine Wave inverter is a PSW.

On our DSDP ALL 120 V plug ins run through the inverter. There isn't a one that isn't on the inverter.

I'm pretty sure that Samsung's reasons for using DC (no reason to think it's 12V) to run its refrigerators has nothing to do with RVing and I doubt that the company sees RVs as a significant part of its global market.

Using DC "inside the box" means that Samsung doesn't have to worry about whether the AC voltage is 120 or 240 or whether it is 60 Hz or 50 Hz. All they have to design is a converter that rectifies the AC and turns it into DC. Most of the "power bricks" that come with laptop computers are designed for 120-240V 50-60Hz and essentially that's all that's needed for the fridge. All Samsung has to do is install a power cord with a plug that is the correct one for the part of the world the fridge is going to.
