24V Inverter

[eagle19952]

Truth is there is NO SUCH THING as a true Sine Wave inverter, only Simulated Sine Wave, due to a "shorter" frequency and duration of square waves, True Sine Wave only comes from the Source {read=generator} - FWIW

Agree

Bruce,

I thought I might read the thread and then comment on your original question, but I confess that I lost interest on page two. I have no idea what was said after that. Actually, I'm not sure that I remember the question....

We've been living full time with a Magnum 4024 for two years. I love it, and I can't imagine needing or wanting something different. I'd read many glowing reviews, and once we decided that our house system was going to be 24v, I never seriously considered a different unit. I would do it again with no hesitation. We rarely plug in, but when we do, the battery charge function impresses me. Ours is not the hybrid version.

With that said, I confess that I've never owned another "big" inverter, so I have nothing with which to compare.

How's the repower project?

I'm not going to get into the urinating contest about what inverters have as far as sine wave, modified or pure. But I can say accurately that older technology modified sine wave, and newer technology pure sine wave are two different products. Even if we all ignore the abilities of newer inverters such as load sharing and the ability to sync up the technology of products that are now being sold is dictating the use of pure sine wave inverters.

I see no issue if someone opts for the older possibly less expensive inverters, as long as they understand some 120V appliances or devices are not going to work, or may even be damaged by the modified sine wave inverters. Some refrigerators for example will work on modified sine wave inverters, but over time it can be expected that the compressor will fail or the controls will fail. An older technology refrigerator such as one 10 or 15 years old may work well on any inverter, but newer ones may require pure sine wave inverters.

Debating the shape of the sine wave pushes the discussion away from the fact that an inverter described as a modified sine wave will not work with some of the products available today.

LOL all of it will be useless when the great EMP hits us I saw that on TV so it must be true  ,this conversation is a classic Bruce ask what would be the best inverter for him

I will say our Crestron systems at the restaurants require a true sine backup battery and a lot of RV's have that system,then you have people living off grid for 40 years with the MS inverters with no problems and with all the conveniences, the true sine inverter is wave of the future till the great EMP hits

Clifford, "wave of the future" now? What is that? A new kind of inverter? Now I am more confused... LOL

Often in these type threads a person will ask if something is suitable and will pretty much state honestly that they have $800 - $1000 to spend.

What good does it do to  tell them about your $2200 latest and greatest deal with all the bells and whistles...And offer no alternatives.

I'll let you know when my Trace 2012 $320.00 (bought off Craigs list) or My Xantrex Freedom Marine 3012  $760. (with pass thru) burns something up.

Not all modified square waves are created equal. neither are the so called pure ones.

    Good point, Don.  In my first post, I specifically asked for "the best" - with cost a secondary question.  I am retired and "on a fixed income" so I'll have to factor in cost, but I want this bus to be my home for as many years as I have the health to do it -- I'm not going to waste money, but I don't mind a wise investment -- by "wise" I mean something that works well now and is reliable over the years to come.  So, I don't mind that people have described expensive units.  I'm going to take their descriptions of their experiences and opinions and put them into the many-factor mix. 
    To have a unit that will take me until I'm 80, it would need to last 14 years and be suitable for the technology of 2028. I think that means that I'll need to go with "what they now call 'pure sine wave but really isn't'" for it's technical capabilities.  I got a bit stung on the Outback purchase -- I didn't do my figures right and bought too small a unit and misunderstood it's listed claim for "load-shifting" versus "load-sharing".  I really appreciate that people have described the load-sharing abilities of the equipment that they've had experience with.  That's been the help I've needed.
    I'm not sure that I'd have replaced the Outback (although the lack of true-load-sharing would have been a burr under my saddle for as long as I had it) for what I've got planned but an engine change makes a move to a 24V house system pretty much necessary.  And 24V on the house system will be better for higher loads of systems like the air conditioning system I have planned for the future.
    I have sort of assumed that buying used unit off EBay is a little risky for complex electrical equipment that's supposed to last 14 or 15 years, esp. since I have not had a lot of experience installing, diagnosing, or repairing electrical or electronic equipment. I think I'll have a good discussion with myself, but it seems that that's a pretty good assumption *for what I need* (not saying that it is the way to go for anyone else).
    I appreciate your input on this thread and the fact that you've taken the time and energy to help - a lot of what you've talked about is "going back to the basics" and that's been especially helpful.  Thanks, and Good bussin' to you!
