JUO:
yes bro

excellent. Noted and bookmarked

Thanks GeorgeD1, our grand Patron and inspirer when it comes to solar and new technologies.

It was a decent review however i have always preferred midnite classic and even common itracer to morninstar due to its lack of aesthetics....i love beautifully made things and this is a criteria for choosing for me funny enuf esp as many of these controllers performances are close to 99% efficiency.

GeorgeD1:
all,
so finally here comes the head-to-head comparison between midnite solar classic 150 cc
and the tristar mppt-60.

1) build
the tristar comes solid as a rock made of an upper cast aluminum and a lower steel body. so also the
midnite. it looks rugged enough and its appearance exudes quality. a mere glance gives one the
impression of high quality.
-both charge controllers take this round equally.

2) installation
both charge controllers are easy to install with both shipping with a battery temperature probe as standard.
clearly marked positive and negative battery and solar pv terminals reduces possibility of error.
- this round is also a draw.

3) setup
setting up the tristar is a little tricky as you'd have to fiddle with the notorious 'dip switches'. from system
voltage settings to battery type selection and equalization, you will do well to read your manual over and over
to make sure you don't flick the wrong switch else you might just kiss your precious controller goodbye.
the midnite classic on the other hand is a beauty to set up. the built-in wizard helps guide you through the set up
process and you could be done in minutes without even opening one page of manual to read. it is that easy.
-the midnite solar wins this round without contest

4) programming, fine-tuning, etc
coming closely on the heels of setup is programming and fine tuning the charge controller.
the midnite solar has quite an impressive list of user adjustable settings that you could carry out directly from the
mngp (display unit). you could also use the wizbang jr add-on to achieve this. and this helps to make the unit very
flexible and user friendly.
the tristar on the other hand is not that easy to program. i've mentioned the dip switches already. to adjust the few
settings available you will need to install the optional 'msview' software.
-again the midnite classic wins this round.

5) connectivity, internet, etc
both charge controllers connect to the internet when properly configured but it seems the midnite classic has a more
seamless architecture. configuring the modbus for the tristar has always been a pain in the ass for me.
- midnite classic wins this round

6) performance, solar harvest, ability to optimize yield even in cloudy weather
i rotated both charge controllers from north facing panels to south facing panels over the course of two weeks and
monitored their performance with the different arrays. i discovered the tristar always being first to wake up from night
mode or 'rest' early in the morning and being the last to go to sleep in the evenings. also conversion wise (dc to dc)
the tristar seems to shine. however what the midnite classic lacks in terms of its inability to wake up on time, it tries to
make up for it by its superb solar algorithm - although it finds itself always trying to play catch-up for the rest of
the day.
for most days, production from both charge controllers were almost equally matched with only a little variation.
- this round is a draw with the advantage tilting more towards the tristar.

7) durability, reliability, etc
like i said in my earlier post, it's still early days yet with the midnite classic cc so i may not be in a good position to tell
how durable or reliable it may turn out to be. however, i can vouch for the tristar as a solid and reliable unit able to
withstand almost anything thrown at it. unless you deliberately set out to damage it, this cc is guaranteed to serve you
for many years to come.
- this round is inconclusive

8 ) scalability, ease of expansion, etc
perhaps the biggest selling point and over-aching advantage the midnite has over the tristar is its ability to produce
between 80 to 96 amps of charging current with a maximum solar array size of up to 4,300w at 48v. that means as a
user there is more room for expansion. you can start with a few panels and continue building up your system on an
incremental basis by adding panels after panels without worrying about changing/upgrading the charge controller.
the tristar on the other hand maxes out at 60 amps which translates to 2,300w at 48v. anything above this and the
current limit alarm set in.
- midnite classic is the winner for this round

9) conclusion
as can be seen, each charge controller has its own strong points and not so strong points. also, they seem to match evenly
in quite a few areas. at the end of the day, its much like comparing ronaldo and messi - both are kings in their own rights -
or comparing apple and android. while one is a closed system and difficult to manipulate, the other is flexible and easily
configurable - but they both excel in what they do.

Seconded!

I'm sold.

https://play.google.com/store/apps/details?id=ca.farrelltonsolar.classic&hl=en

Have you tried the app in the link above?

hello barrezi,
thanks for the link. i will certainly try out the app and let the house know what i think

dapsyra:


Nice comprehensive review. Welcome to the family. Thank for sharing.
The Classic 150 can go as high as 4672W at nominal 48V. Mine is running very well on a 4500W array with peak instantaneous harvest of 4460W
The Classic 150 carries a 5years manufacturer warranty. Feedback from customers on their users' forum show that Midnite Solar honours this warranty promptly without trying to shift blames.

That app is the best Android App available to monitor the Classic CC

For windows environment, I recommend this app by Midnite Solar

http://www.midnitesolar.com/firmware.php?firmwareProduct_ID=2

You can also use this app to configure and fine tune the CC in a very easy to use graphical environment

@GeorgeD1, change the MPPT Mode from "Solar" to "Legacy P&O" and watch the Classic dust the Tristar in performance, early wake-up and late shutdown. The solar mode is optimised for clear skies while the Legacy P&O mode is optimised for cloudy skies. It is cloudy all year round in Nigeria especially around the coastal areas because of our tropical climate.

Head for https://mymidnite2.com, register and then configure your Classic 150 to upload logging data to your account. This will give you beautiful graphical presentation of all vital data from your CC.

hello dapsyra,
thanks. i'm still experimenting with the midnite solar. i will try changing to the "legacy P&O" mode and see if it
finally overtakes the tristar in terms of daily harvest.

NiyiOmoIyunade:
Finally, the much promised review from somone here in Nigeria. A man of experience who thoroughly knows his onions.

So it appears the Midnite Classic won over the MorningStar overall - though I find the setup complexity issue relative having setup quite a few MorningStar CCs - I don't even think about it these days - there is something comfortingly solid & reliable about flipping dip switches.

I wanted to point out that the MorningStar is not limited to 2300watts - more like 3200watts output power as the below capture from my LiveView shows.

[img]https://4.bp..com/-BQvgsfBjyvc/WaFO4mUUqfI/AAAAAAAAAak/Lzt0ImVM2-IDQo0JJauvHgZROwUAeqDIQCLcBGAs/s1600/CC.jpg[/img]

So the jury is out on whether the Legacy P&O mode will clearly beat the MorningStar - hopefully you get a chance to try that and report to the house.

So I guess the next review would be the Magnum PT100 vs other CCs - hopefully someone would do the honors

NiyiOmoIyunade,
indeed the morningstar can do up to 3200w at 48v. please forgive my error. the point i was trying to make is the
overall higher capacity of the midnite @83a 48v as against tristar's 60a at same 48v.
and yes, those dip switches really give a comforting feeling knowing fully well that no software glitch can suddenly
change whatever settings you have made.

babaegun:


@GeorgeD1

Thanks for this wonderful review of the Midnight Classic 150. Quite insightful. From the pictures to the analysis, everything was just fantastic.

From the comparison, I was so sure the Midnight Classic will carry the day and you just confirmed it.

One thing you fail to mention though which I saw from the picture, the Midnight Classic can also work with Hydro & Wind power aside Solar. I think this is a plus too. I doubt if the Morning star have that capability. That triple feature is missing in most charge controllers. Most ship with the Solar capability ONLY.

What about the Android/ios/windows apps suggested by dapsyra,, the Internet ready features. The Midnight Classic is really wonderful because in other Charge Controllers, you will have to pay more to access those features.



JUO is really the man! Any day, any time. His Customer / After sales support is simply super. Don't know if the guy did ITIL self .

Once Again, GeorgeD1, Thanks a million.

babaegun,
you're welcome. thanks for pointing out the wind/hydro capabilities of the midnite although the tristar mppt-60 also incorporates
those features with the right dip switch settings. if i had mentioned it, both controllers would have drawn that round.

kiekie1:


Welcome on board .. Nice you finally got the midnite order tru James ! My only dislike about midnite classic is the thermostatic fans which kicks in almost every time (2 underneath & 1 on top) & must be serviced when they get weak to avoid internal temp rise . Secondly it comes with real small 16mm ports for solar - battery cables , if you were using 25mm cables above on morningstar, you will find it a bit difficult to fix on midnite . . overall , its a nice mppt ! I also await users of the magnum mppt to attest -give a review on its ruggedness

hello kiekie,
thanks. i also do worry about those midnite solar fans and in comparison the tristar seems quiet but i guess that's the
price for its higher current carrying capabilities compared to the tristar.

dmerciful,
i'm glad you found the review useful. remember however that i've only had the midnite for less than a month.
so consider this as a work in progress. i'm still experimenting with quite a number of settings and observing its
performance. who knows? three months, six months or even one year down the line i might decide to do another
review and a lot of things might have changed by then.

@GeorgeD1 welcome onboard. I've been using the classic 150 Mppt since March 2016. I hardly go and check the harvest since my mind is at rest.
Another good feature is the hyperVoc.
With this feature, I now use 4X4 configuration to instally 16 units of 250w poly panels. The performance in cloudy days is superb. Though I don't think I recorded any significant improvement with the legacy P&O. But will try it again soon.

@Juo, you now see all I've been discussing with you. I am glad you are doing it positively.
More blessing sir.

Pls do post prices too for informed decisions for others.

GeorgeD1:
now, for my vote of thanks:

juo is the man of the moment!

it has really been a very tortuous journey for me. i set out looking for the best and most economical way to replace my
tristar mppt-60 which obviously was undersized for my solar array and i searched in a number of places, contacted
quite a few sources both here and outside the forum and ended up disappointed. i noticed that most sellers still carry prices
of items calculated at an exchange rate of 450 to 550 naira to the dollar. over seven months after dollar has reduced to 365
naira and below, these peeps choose to bury their heads in the sand and pretend not to be aware of the current realities.
in comes juo the life saver! here was i chatting with this unassuming seller on this thread via watsapp and narrating
my ordeal to him and the next thing i knew he was already making arrangements to get me a midnite solar classic 150 at an
incredibly mouth-watering price. initially i thought it was all a joke until i got that much anticipated call from him telling me
that my cc was ready for collection. at the end of the day when i compared what i paid to the amount that a popular online
store is selling their midnite, i just shake my head in disbelief.

not only has juo proven to be a reliable guy to deal with, he has always been consistently delivering quality products at
unbelievably low prices and this successful deal adds another feather to his cap.

Juo is just the definition of a GentleMan.
One love brother.

bigrovar:


Thanks for this review. It adds to the heap of knowledge on here. I have always suspected the midnight classic is indeed the lion king of offgrid charge controllers due to its legendary status among offgriders. I remember reading somewhere that they and Outback are a branch from the same tree and their founders it was who pioneered the concept of MPPT solar controllers.

About JUO. He is the most understated Underestimated unassuming seller in this part. I remembered one time one of my controllers went lemon and even though it was under warranty and a replacement was on the way from the manufacturers, the time lapse meant I would be without solar insurance policy for close to 3 weeks. This happened on a saturday, I called JUO explained to him my situation and informed him of my need to have a new controller the next day in Abuja... The fact that I had the controller in my hands is not the exceptional part, it is that JUO sent the controller even though I explained to him my tight financial state and the fact that he might not be paid until much latter. BY sunday evening I was taking delivery of the charge controller and crisis was averted.

Just recently procured 4 Front Access AGM batteries from from him for a neighbour, The price he offered those batteries was so mouth watering, I give him 20K back for the boys. My neigbour called me last night to thank me for the batteries. Said they are working better than what he expected.

hello bigrovar,
indeed, a gold fish has no hiding place and juo has proven to be the man with the golden touch.

but while we're here heaping praises on one of our own, it may not be out of place to give some advice
(and sound a note warning) to the numerous shylock traders teeming around in the internet space. they pop
in here and browse through our thread and pluck in much needed knowledge which they use to update
their overpriced solar wares.
first of all, the advice: please wake up to reality and reduce your prices! the same price adjustment mechanism
you used to hike your prices when dollar rose steadily from 220 to 550 naira should be used to re-adjust those prices
downwards now that dollar rate has fallen to below 370 naira.
now the warning: if you choose to stick your heads in the sand and feign ignorance of current realities, savvy
peeps like us will keep going the juo route! we know where you source your wares and we know how much you
make off each imported item you sell. we only chose to patronize you in the past because your prices were reasonable
and we couldn't be bothered if you made a little income from your sales, afterall, you're not a charity organisation.
but when your profits and mark-up starts getting in the region of hundreds of thousands of naira for an item that
we know can be gotten for much less, then you will keep losing our business! pure and simple!!

Actually, you can easily fit 25mm cables into it. It's a technique thing. Good thing I spoke with their "support team" before installing mine.
And the fans don't fail as often as speculated (Outback, yes; Midnite, no) though not having moving parts is usually an advantage.

There are quite a number of Classics out there. If DIP switches are your thing, there's a Classic just for you - the Classic Lite. There's always the option of a MNGP, should you want visual monitoring of your CC's performance.

Chuckdee:


Lovely unbiased review indeed. Thanks GeorgeD. The Midnight Classic 150 is an excellent CC, and I have no regrets ever buying one. @ bolded above and just as dapsyra has rightly pointed out, it take take more than 4300W, I have a 4500 setup and it han2 fans kick in to always to cool down the CC when needed however, the top fan you mentioned is the Turbo Fan which seldom kicks in, infact I have had mine running for over 5 months and it has not for one day been activated. Its a no brainer that your CC should be installed in a well ventilated area to also aid in air-flow and cooling. The fans are very reliable too and I know people that have used classic 150 for over 5 years w/out a fan failure...

Note that the "no fan" units (Tristar for example) generally can not handle as much powelassic 150, and require much larger heat sinks to manage what they do. It would be interesting to test the actual operating temperatures of two comparable units and see how the cooling difference affects longevity. If the non-fan type really runs even a bit warmer it will have shorter life, all else being equal.

I think its a great feat to achieve upto 96V in such a small form factor like that of the 150.

I know guys who load Classics with twice the array power upper limit. The primary disadvantage is the power loss in good weather (plus cost inefficiency). In poor weather (which is common in areas guys often practice such), they win. On sunny days, the Classic simply unloads the excess power by throttling back on output. Same as you and I would have when attempting to charge a full bank on a sunny day.

On nominal 48V systems, The fans hardly ever kick in and when they do, it's at low RPMs. On 24V systems, moderate fan spins. On 12V systems, fans run almost all day on mine, buzzing like a dynamo (I use the same 3kW array each time). It appears the higher the current output, the hotter it runs (not really a total power thing). Also, the higher the hower thing). Also, the higher the headroom MPPT voltage difference, the sooner the fans kick in. (I'm sure you saw the transformer while installing it; no small feat using that small thing for tl feat using that small thing for that power). That's my observation from fiddling with the Classic 150.

Regards longevity, the grapevine states Classics are really hard to kill, even when you try to.

To JUO, I have this to say:

You are gradually stepping up in all spheres. Your name has been spoken in the open and behind closed doors. You've proven a business principle - trade volume trumps margin. The one thing which trumps them both is quality of service, something which many can testify you have in no short quantity.

Do you know there are 3 heavenly bodies capable of casting a shadow (meaning they shine through even in overcast skies)? The sun, the moon and a particular star (actually the planet Venus but it's the "star" sea voyagers and desert sojourners keep their orientation by). Others might soon have to use your service standards as a yardstick. Keep up the good works and your star will shine even brighter.

nisol:

Please could you elaborate.

Thanks

I echo Nisol here - the Panel's wire appears burnt from carrying more current than it was rated for for quite sometime - indicates a short circuit (+ve & -ve wires bridged) or other current overload condition perhaps due to inferior/too thin cabling used.

I think this could have been avoided if you had a suitably rated DC breaker on each incoming PV string. The breaker would have tripped off protecting the cables from burning up - NB: You should size your breakers to protect the cabling and not your equipment.

I am worried though that it was the panel's wiring itself that melted and not the attached cables carrying power to the charge controller - it indicates possible quality issues with the panel itself. What make/brand are the panels? I think they can be repaired though if you take the panel to Alaba and similar places so all is not lost.

At the minimum you should audit your system for short circuits, exposed cable insulation (peeled wire/wiring), DC Cables properly rated to carry the maximum current? before you proceed further - a system is only as strong as the weakest component therein.

Best of luck!

sorry for your loss my brother.



i will like to know the following:

1. Did you mix PVs of different watt ratings?
2. What is the make of the PV?
3. Did you cut off the MC4 connectors to make ur 3x 2 strings? (check the possibility of insulating tape wearing out and short circuiting the string);
4. Check the surface to see if the burnt section has affected the module (if yes,
you can loop/byepass that section/solar module of the PV, you can PM for a link to how to fix it)?
4. Use screwdriver to Open the Terminal Box and take readings directly from the terminals (you can get a local electrician to read-off amps etc if you can't), (also where you can't get an electrician or a meter, as a DIY -get 12v motor vehicle bulb, wires and trace & check each of the strings within the PV to determines which can be salvaged).
5. You will need to get / replace all diodes. i have seen a case where 2 diodes were plugged in and not soldered in-place and you know what that means).

you will get over it, cheers.
