Pure Sine Wave Inverters

Postby Chris C » Sun Mar 19, 2006 9:31 pm

Okay, shoot me! I DID use the Search button, but came up with more hits than I could read through..............I know, I tried to!!!!!

I have to have a pure sine wave inverter...............minimum of 300 watts. Don't know anything at all about which brands are better than others, etc. Can anyone help me?

I think that's a modified sine wave interter. I need PURE. The people who make the C-PAP machine my girlfriend sleeps with say that it takes a minimum of 200 watts pure sine wave or the machine will "vaporize". Yea, sure! But at least I know they won't honor the warranty if we use anything else.

Thanks Mike. I appreciate the effort.............but I can find plenty of inverters on the internet................just don't have any experience with which brand is quality and which is trash. Was wondering if anyone on the forum has had specific experience they could share.

My suggestion would be to try any of your major electrical Retailers. The better brands will always cost more but they usually have a better warranty contract than the so called cheapies. I don't know what you Guys think of Radio Shack gear but they appear to stand by their products fairly well.

I started my search by trying to find some reveiws. I had no luck finding reviews on Pure Sine Wave Inverters... but Amazon will often list reviews, as well as epinions.com

Hope someone here has a better answer for you...

Chris, I don't know if any brand name is better then the other, but i do know that the more you pay for the inverter you find, the better your chance it holds up..I always believe you get what you pay for.

Paul, when I went to Radio Shack they tilted there heads at me like a puppy does when it hears a high pitched sound!!! :shock:

Jiminsav, I usually agree with that philosophy, but it doesn't always hold true. That's why I'm trying to find someone who has had first-hand experience with really quality interters.

Thanks for your efforts, Mike. Maybe someone will. :thumbsup:

I have a c-pap. Mine will run off 12 volt. I had to purchase a 12 volt power cord for $50.00. :shock:

I use it with a deep cycle battery & it will run for 4-5 nights. I put it in this battery box for camping. http://seasense.com/cgi-bin/htmlos.exe/003.3.2623472396000007735

Her's won't run on 12 volt. The tech department of the company who makes the machine said only a true pure sinewave 200 watt minimum inverter would work. This one uses 40 amps in 8 hours (a typical night).

Inverter manufacturers

Postby Guy » Sun Mar 19, 2006 11:07 pm

Dear Chris,

Here is a list of manufactures and some suppliers and info from phred's poop sheets. RVSOLARELECTRIC.com is real popular with disabled RVers

Heart Interface. (800) 446-6180. In WA (206) 872-7225. www.heartinterface.com If you buy a Heart, use this same number for tech assistance.

Trace Engineering. (360) 435-8826. (www.traceengineering.com) No 800#. That's OK. RV Solar Electric (below) has all their data sheets and has an 800#. Once you buy one, Trace will accept collect calls if you have problems.

STATPOWER. A very nice line of inverters. Make the highest rated true sine wave. (800) 668-0003. (www.statpower.com)

EXELTECH. Very highly rated line of true sine wave inverters. (800) 886-4683. (www.exeltech.com)

PowerStar Products. (800) 645-4004. (408) 973-8502. Use same 800# if have trouble.

INFO FROM VENDORS/DEALERS: Some send free stuff, some charge for catalogs. All are great, Honest, trustworthy.

RV Solar Electric. 14415 No. 73d St., Scottsdale, AZ 85260. (800) 999-8520. (602) 443-8520. (www.rvsolarelectric.com) Nobody knows more about solar systems, inverters, etc., (for RV use) in this country than these people. This is where experienced RVers go. Call for their free informative newsletter/catalog. Get on their mailing list. Buy their book, the "RVer's Guide" (info on solar energy, inverters, much more) for $12. These people have been listed in no less than "The Whole Earth Catalog" (we're talking a big recommendation here), as having "What you need to know if you're going to live in an RV." Their info a "must have."

Real Goods Trading Corp. 555 Leslie St., Ukiah, CA 95482. (800) 762-7325. (707) 468-9292. (www.realgoods.com) The "Solar Living Source Book" this company uses as a catalog is 690+ pages of valuable info. It's a text book on living a better way. An excellent staff of experts will answer your questions. The book costs $24.95. (But if you're a cheapskate, get your librarian to borrow a copy, if they don't have one, under ISBN 0-930031-82-2-etc.) Real Goods website has most of their info free. Another "must have."

Backwoods Solar Electric Systems. 1395 Rolling Thunder Ridge, Sandpoint, ID 83864. (208) 263-4290. (www.backwoodssolar.com) No 800#, but they do return calls at their expense if you don't take advantage of them. Free Catalog/Planning Guide (is also the best source for generator selection info--they tell it like it really is) . This is another textbook. Good deals on inverter trade ins. Free periodic newsletter has latest tips and is most valuable.

West Marine. Box 50050, Watsonville, CA 95077. (800) 538-0775. (www.westmarine.com) Giant catalog ($5 refundable) with page-after-page of tips, how-to's and product comparisons. You really need this catalog.

Wrangler Power Products NW. We spend big $ on equipment, then buy flimsy junk at RV and discount auto stores to tie it all together. Doesn't make sense. Do yourself a favor and get Wrangler's free catalog. Heavy-duty cables and connectors, fuse holders assembled to your specs, heavy-duty switches, lots more. Top quality. 4444 S.E. 27th Ave., Portland, OR 97202. (800)962-2616. (www.wranglernw.com)
Regards,

Guy

Chris,

Try doing a search for Xantrex Sine Wave Inverter XS400, I found them for about $330.00.

I believe Xantrex is now the largest inverter manufacturer. They bought up several inverter companies a few years ago. I have a couple of their 1000 watt units.

Thanks for all the links, Guy. I'll check them out.

Q, I've heard good things about Zantrex. I'll check them also. Thanks.

It is Xantrex

Postby Guy » Sun Mar 19, 2006 11:43 pm

Dear Chris,

It is Xantrex, not Zantrex, and they have been buying up most of the manufacturers. They are the company that makes the ones that are sold at Costco. I think they bought either Heart or Trace for their high end True sine wave products.
Regards,

Guy
