Northern Tools has a SUNFORCE 11230, 650 watt, true sinewave inverter. I need one to power computers, TV, refrigerator. Has anyone any experience with this brand. Their five star rating system says no rating yet. It is $249.99. I'm told that motors and computers run better/cooler w/sinewave, so would like to use that. Any other solutions would be welcomed. All of them seem to have about .5 A at idle, which seems like a lot to me.

George,

Take look at the Xantrex PRO Watt SW-2000. I had to pay $479.00 for mine
from Camping World but I've included a link to a company that sells them for
$369.00!

Square wave, generally a cheaper version of SineWave, may work on most 120v ac items.

I believe because the SquareWave inverters cut abruptly, as in the name SquareWave, there is a power loss, in some cases noise, heat loss and power loss.

Some have said they use them for Micorwaves but the microwave cooks much slower than on the regular Sinewave power you get from the generation stations and closely duplicated by the SineWave Inverters.

If you turn to the SineWave units, be sure to find the word "SINEWAVE" and not SQUAREWAVE. Some ads get rather loose at telling you this and some don't even mention it.

Price wise the SINEWAVE will be a bit more but you will get more out of it and less power loss.

West Marine has them but be aware they are a marine distributor and have the higher Marine prices. Some times the sales are pretty good.

Xantrex would be a good name brand, but I thought I heard that they were being bought out. I am unsure of that.

If you are using the inverter while running the engine, you are good but if you plan to run on battery, you will need to beef up your battery supply.

Inverters are a nice QUIET version of power when compared to the Onan GenSet, but you have to prepare more to be able to use it.


LarC (Having played with the inverters but thinks the batterIES needed are excessive.)

Further to Larry's post, be wary of the term "Modified Sine Wave". This is just a marketing term for square wave!

Inverters are great, but don't forget you can't get something for nothing. Basically (without getting into AC complications as power factor etc) power in watts = current (Amps) X voltage. Since your battery voltage is 1/10 (12V) of the usual AC voltage (120V) you are going to be pulling 10 times the current (OK more like 11 times with inefficiencies). So your 1,000 watt microwave will take about 100amps from your batteries. Its great for a quick reheat, but cooking up a batch of baked potatoes is going to take alot from your batteries.

Xantrex was Trace, a US company. Then I believe a Canadian company purchased them and moved the design and company operations to Canada, with most production to China.

I also recently heard that Xantrex was bought out by someone else. It is hard to tell these days who owns what, and what quality level they are producing, but Xantrex (Trace) did make good stuff. Lets hope it continues.

Thanks for all the replies and opinions sine vs square. I'm committed to sine and have a large 1380 A battery to run it. Anybody familiar w/the brand and should I just trust Northern and go ahead and buy it? I don't need 2Kw. I'm also concerned about the .8A drain on larger unit.

I have a friend who has had very good results with inverters from this company, and they have super low prices. Based on his experience, you might consider looking at them. Low prices, fast shipping, and what seems to be a good product line.

Here is a sample url. You can look around the site for other ones.

George,

I didn't worry about the .8A drain as I located the Xantrex on top of the
hot water heater which has an access door and I can switch it on and off
easily.

Here are some pictures of the installation.

http://www.gmcmhphotos.com/photos/showphoto.php?photo=30656

Main use will be to power the microwave and Keurig coffee machine.

Just a fast comment, whether it has a bearing here or not depends on the reader.

I am aware of the original company, TRACE.

When Xantrex bought them, they changed the inverters.
The original TRACE 6024 ( I think thats the number ) Had some unique functions and when the Xantrex 6024 was produced, some of those functions had been removed.

I believe Xantrex did this to the entire TRACE line of inverters.

I hope, if there is a new owner, they don't down size the technology again. TRACE Was one of the best inverters available but it seems to be losing its quality.

LarC ( Still following TRACE/Xantrex Inverters but not happy with the changes in technical design )

Wow nice tight installation, hope you don't spring a leak in the water system.

My worry is exactly that; the inverter is going to power the refrigerator, so couldn't turn it on and off w/o a lot of added circuitry. Thanks for the info Rob.

Larry,

It's hard to tell but all the plumbing is below the level of the inverter
and there are no vents in the side of the inverter.

I will wire the output when I get back to the USA next May.

I only made a comment because, isn't the water piping PRESSURIZED from the water pump? About 30 lbs psi as I recall??? ALSO, If you have the OEM water heater, you have the source and return water line from the engine to heat the water heater. That is also pressurized.

The last trip I took, the hose failed and water went everywhere.

Just offering a heads up, though not really any of my business where you put it.

LarC,

You are 100% correct in noting that water could / would go everywhere and
probably get into the inverter.

I'm happy to provide some more information as to why I felt locating the
inverter where I did posed an acceptable risk to me.

1) The house water is all copper and in really good condition albeit 30+
years old.
2) The rubber engine heater hoses are brand new and held on with brand new
stainless steel clamps.
3) We do not leave the city water or pump on when we are not in the coach.
4) We do not leave the city water or pump on when we go to bed at night.
5) If there was a leak in the house water system the pump would run when no
taps were turned on and alert you to that fact.
6) The inverter will only be switched on to run the microwave or Keurig when
we are dry camping in an area where we don't want to disturb our neighbors
with the noisy Onan. The photo that shows the front of the hot water heater
with the inverter sitting on top of it was taken through the hot water
heater access door in the panel in the side of the passenger side bunk. If I
open it up to turn the inverter on and find water everywhere I won't switch
it on.

BTW we learned items 3) and 4) the hard way!

You're right! I normally have an acute grasp on the obvious but sometimes
the ole gray matter lets me down! ;-)
