Re: magnum me2012

eva,
if you are wondering about something specific that you are concerned with about the inverter then if we dummies can't answer it then know that halfcrazy and boB are affiliated with magnum (correct me if i'm wrong guys) and may be able to answer.

bb,
same wavelength, different method.:roll::p

Re: magnum me2012

well you will be happy to know that boB and robin (brothers) formed the original outback company. the designs and such for the original outback products came from them and they are now with midnight solar. i'm not sure of all of the ins and outs with companies and affiliations, but magnum is good.

Re: magnum me2012

I bought an MS2812 over two years ago. There was a typo error at their website pages on whether a remote was included (s'posed to be an option, the page said included). I posted here about it. They corrected the website and also shipped me a remote at no charge.

I was very happy with it and I bought a second MS2812 last year with another remote. I have my home split into two circuits (1) lights, entertainment and A/C and (2) appliances. Both inverters have been working flawlessly.

These inverters cannot have any settings changed without a remote, unlike any other inverter I've owned. Search and charge parameters are set differently on my two inverters but couldn't have been without the remotes.

The first remote's backlight didn't work (Magnum offered to send me another but I declined, thanked them again for giving me that one, and explained that I'm able to read the screen without a backlight).

The second remote, although looking ALMOST identical, was built with a slightly larger display screen and has functioned perfectly including the backlight. The two remotes are mounted a couple of inches apart and comparing the two is the only way to notice that they are using a different LCD screen, I'm guessing because they had a backlight problem with the earlier versions?

Were I to need another inverter, I'd order a Magnum again (unless the reason I needed another was an early failure of one these).

Thanks for your input Solar Panda.\

I decided to go with the Magnum and a remote.

he is PhilS and solar panda is just a redundant status name based on the number of posts one has.

Re: magnum me2012

"Also to clarify boB nor I are affiliated with Magnum boB worked for them for a spell and I use a lot of there products. "

ok, my goof. sorry for the misnomer.

You can not go wrong with Magnum for the money. .

I have asked this question elsewhere in this forum; but since I have not gotten specific, clear, and straightforward answers yet, I asked it here once again:
Will (or can) a modified wave inverter harm in any way, or even damage, a new lcd tv, a new refrigerator, or (and this is much more important for me) my sanyo mini-split air conditioner?

Are some “modified waves” better than others? Are MAGNUMS MSW better, or more reliable, in said respect, than a Samlex, or an Aims?

Please, do not redirect me to NAWS article about inverters; I have read it, and many others, many times. What I would really like is your honest opinion, because, for $1,100 (NAWS price for a Magnum 1800) I am seriously considering putting away my new GO POWER piece of junk and replace it with that unit (until I win the lotto and buy the Outback).

i'm sure it has been said elsewhere on this forum, but i don't recall if you were specifically answered or not elsewhere. i might add cariboocoot made a fine answer for you.
reiterating some of what he said i can say that it is unlikely to have your lcd tv damaged by a modsine inverter anymore-so than a sine wave would, but that does not always mean all lcd tvs will operate right or correctly under all modsine inverters as they just won't be damaged. as to the refrig and ac these can be damaged. i won't say with definity that damage will occur as it can indeed vary by inverter and appliance product used, but minimally extra power and heat will be dissipated by the appliances involved. remember heat is the enemy for products to last and damage may not be as readily seen as it may just rear its head as a shortened product lifespan.
as to getting rid of your, as you put it, "go power junk" that depends. if it is an inverter that is modsine then going to a sine wave inverter is always a good idea with the appliances you have in mind to run. do understand that there are differences in inverters and all can theoretically be considered modsine. we make a distinction for those that output a waveform that is consistent with the same requirements as that for utility electrics for their total harmonic distortion or thd and they must be at 5% thd or less. an inverter then at 5% or less thd qualifies as equivalent to what you may plug into at home.
are there differences? yes, i'm sure there are, but as coot said, they often aren't publishing those differences. if you find a modsine inverter that gives a spec of 6% thd, this is just outside of what is considered to be sine wave and would be a quality modsine inverter waveform as opposed to another that may be at say for example 10% thd. both may or may not cost similarly or they may have other features. would such a 6% thd modsine inverter be worth it? maybe, as the sine wave one being compared to may only be say 4.5% thd and way higher in cost. many of the ones we are familiar with from xantrex, outback, magnum, etc are usually 3% or better and often have their thd published as it is good enough of something to have in the limelight.
should one worry in my example that 6% is still out of range and is not being considered a sine wave inverter? if you know it is 6% then i would not worry and i would use it. it would be true that it would have 1.5% more thd to dissipate over my example sine wave inverter with 4.5%, but in the mix of things that difference may still be too insignificant to worry about. it would be double the thd over the many sine wave inverters we are familiar with though. it is rare to see the thd specs on modsine inverters as many aren't something to be proud of, but for the designation of sine wave you know the thd is lower and at least utility comparable.

I CAN measure my Sanyo through a Kill-A-watt if it'd be meaningful for you JESSICA. Because of the way my system is configured, I can "plug" my Sanyo into a Xantrex SW2512 (56 step inverter) and take readings for you, too. I'm not totally adequate in understanding the PF factors, but I seem to remember one of the Kill-A-Watt buttons measures that. If a reading will help you, I'd be glad to do it.

Lemme know if I can help.
Phil

It is always a pleasure to know people who understand the meaning of courtesy and kindness. Thanks, Phil.

Nevertheless, it will not be necessary, first because I have my own kill-a-watt meter, and second, because I realize Caribooocoot’s advise is indeed a piece of true wisdom: “$500 buys piece of mind and a sure-thing for running any equipment..”

Thus, I better wait until I have the money to buy the “real thing”.

My psychological problem comes from the fact that I am really upset with myself, because I put $800 in a new pure sine inverter (the Go Power) that I cannot use to power my Sanyo because output voltage is just too low, and thus, a lot of sun power goes to waste from midday to around 4:00 PM. I will not risk my sanyo running it under voltage.

Thanks for your advise and your kind offer.

César.

Re: magnum me2012

I installed my Magnum 2812 True wave inverter about 4 or 5 years ago and I have not had a bit of problems with it. I guess the bigest problem with 2800 watts is that it beckons to you to find more stuff to hook up to it! Good inverter. The only negative thing is it uses more power at idle than it's competators.

Looking at the manufactures website:

"Exhaust Air Vent - ventilation openings that allows heated air to be removed by the
internal cooling fan."
