    It has been in the works for quite a while, first saw it on a price list released in error back in July or so, but at that time they said availability was unknown.

    The new flier is the first "official" mention of it.

    That's funny... Even ~EYE~ didn't know about the Classic before I left OutBack !

    BTW, we heard that Morningstar was working on an MPPT charge controller around 4 years ago !

    >> Any updates?

    No updates except that it is still vapour-ware. Some alpha testing is coming forth-with. It is very cool though !
    The Classic is WAY more complicated than the MX was, as I remember.

    I think someone in Arlington WA told me about, I knew about it before your did :p, their are a few of us kicking around that know most of whats being worked on.

    I've known about the MorningStar unit for sometime, had a unit in my hands last August for a minute :) , the link to my site is the first time I'm aware of MS approved of posting a spec sheet, which they provided.

    It's too bad that the morningstar MPPT will ~almost~ but not quite work with a 48V PV array.

    Thats what I thought at first, but in reality, being a 200watt 12V/400watt 24V Mppt controller it really isn't an issue.

    Re: New Morningstar MPPT Controller

    It should be great though for RV's and such that just need a small system and want to use something like a single 190 watt 35 volt panel.

    Re: New Morningstar MPPT Controller

    200 watts @ 12 volts?
    Hummmm
    Can't wait for my 5 units to come in so I can wire them in parallel, to replace the MX-60 :p

    Re: New Morningstar MPPT Controller

    There are other companies that have small MPPT controllers --- have you guys seen these?

    http://www.genasun.com/genasunsolar.shtml

    They make MPPT effective for panels as small as ~ 40W (up to 110)

    $ 140.00 for a brand of which nobody knows anything about is a high price.

    The well recommended http://www.morningstarcorp.com/products/SunSaverMPPT/SunSaverMPPT.shtml
    200W, $230 at http://store.solar-electric.com/mosumpsochco.html
    Also, the genasun appears to not have any adjustability for different batteries. (factory option for different cell chemistry.) They subscribe to a 1 voltage setting fits all philosophy.

    Other specs / features missing from the Genasun controllers: absorption voltage spec, and temperature compensation.

    Re: New Morningstar MPPT Controller

    I'm new to this and I've never used anything other than the SS-MPPT, but with that being said I( think it works pretty well.

    It makes a little bit of a whine when in operation, but unless you sleep next to it (and during the day) it's probably not even noticeable. Despite all of the statements in the manual about heat and airflow, I think you could probably get away with mounting it in a small unvented enclosure without a problem as long as the ambient temp is reasonable.

    It has a programming mode where you can change every setpoint for charging and LVD on the load terminals. The software is nice in the fact that its very configurable (and free!), but it has a few bugs that take some getting used to. You can build your own custom views with exactly the data you want to see and where you want it.Unfortunately, when you remove a piece of data from your views it moves the labels up, but the values stay where they are. It's easy to re-build everything in a new display, but it'd be nice if that went away. There are only two values that I wish it had (Kwh load and array amperage), but if I really needed them I could calculate or measure.

    I've been having a problem with it cycling back and forth between bulk and absorbtion mode, but that's because I'm using a bunch of old batteries in parallel that are starting to have a lot of internal resistance, not because of the controller.
