An informal poll for all the Samsung owners, what inverter do you use to power to when not connected to shore power? (Pure sine wave or modified?)

We use pure sine wave. Have found that the microwave/convection oven works better on pure sine also.

I use the Magnum 2800 pure sine wave inverter. It runs everything better and is a much better inverter than my old Xantrex that you couldn't get repaired or get parts for.

Denis,
Pure Sine and Magnum 2800, works great.

Original Modified Sinewave.

According to Scott, the pure sign wave inverter is the best bet... unfortunately ours is a magnum inverter ME2000
S/N N1-01613
And according to Kevin Waite,
ME = Modified Sine Wave
MM = Modified Sine Wave
MS = Pure Sine Wave
MMS = Pure Sine Wave
I am clueless as to what the difference is there but Modified Sine Wave is not Pure Sine Wave, I guess that much is obvious. I spoke with another electrical engineer freind who had the following to say... I just share it FWIW:
I'm not a fan of a residential unit for rv use. First, the auto defrost models just draw too much current continuously for it to be a reasonable solution for boondocking etc. Most of these refrigerators use about 3amps@120v which equates to 30+ amps @12v - requires significant generator/solar output and storage (batteries). It's ok if you don't boondock and are powered by the grid. I think your approach is the best - watch this carefully and install the auto deploy fire extinguisher.
With regards to inverters, of course sine wave is the best, may not be the most efficient and costs the most. One thing about inverters, they are very very high current switching regulators operating against inductive loads in the case of a refrigerator - you must buy only the best model available, ie Magnum, Xantrex etc or they will fail at some point. At the high dc currents these inverters operate at, they could catch on fire - so the fire hazard is not completely gone by going to residential type refrigerator - the device to fail is different.find experts with opposing conclusions

Hi Joe,
Just a couple of comments. I am neither an engineer nor an expert but I do have a Samsung fridge in my coach. Normal running load according to my Xantrex control panel is 1 amp at 120v AC (120 watts). That's approximately 10 amps on the DC side. I've seen a little higher at times, about 1.5 amps, and figured it was the defrost working. But this seems to be a rare event. This certainly wouldn't cause a 2kw (rated at 16 amps at 120v) or larger inverter any problems.
I haven't heard anything from this or any other forum regarding a charger/inverter catching fire. I am I alone on this?

You are not alone.
I have a GE Fridge and a Magnum MS 2800 Inverter.
I see the same results you do, and have NEVER heard of a Magnum inverter catching fire.
I think the electrician attended school before Energy Star came in to being and is way behind the times, and is giving bad advice.

I have 4 8D,s and went to the Magnum 2800 because of its higher charging rate.

That's what I like about this board....no shortage of opinions.
OK, if we open it up to anyone with a residential fridge...what inverter are you running?
My original post was to Samsung owners because the Samsung supposedly allows use of a MSW inverter.

As a point of reference. There have been many (including myself) that have/do run their Norcold 1200 on inverter power while going down the road. The electric heaters in the Norcold draw just under five amps AC. That's 50 amps DC! After 7 years and over 55,000 miles I have had no problem. The alternator on the engine is easily up to the task.
I'm thinking I am going to save fuel by going to the Samsung.....................
