Breaking news!!
The first off-grid Solar house in Lagos

udy821:
i even got 20.1amps today but my fone wasnt any where close to quickly snap

earthrealm:
so thanks, am considering 3 options.or a combination of any 2

1. reduce batt bank to 2 units.
2. set timer to power fridge only at night [note, its usually the fridge 190w and 1 laptop+chargers totalling additional 100w that may be on during the day when fridge is on too].
3. reduce fridge runtime to 5hrs daily in the 9am to 2pm time band

wch would you advice i implement, or beta still recommend additional options, that doesnt require more expenditure of funds

earthrealm:
&bigrovar, whats the size of ur solar array?..i see u hv only 2 units 12v battery..and your load appears tobe even more than mine

nice point gents.
part of the problem was the fridge, hving a 130w energy nameplate, but clocking in at 190w on a wattmeter, it was while trouble shooting that i made that discovery...the extra 60w x 8.5hrs is over 500w lost daily, i initially tot my consumption was about os less than 2kwh, based on the 130w x 8hrs + the other small loads, thus with my 7kwh daily generation, i hv 5kwh to feed the battery bank.

am considering this option of programming the fridge to run at night, thus hving all the energy produced during the day go towards charging the batts. has anyone tried this unconventional approach,
i have 6 x 250watts 24v panels on a 60amp epsolar CC, i dont thinki can add an additional 500w to the panel bank, as that may exceed the rating of the CC, n upgrading the CC to 80amps isnt a viable option now..based on funds.
will take the fridge offline for 3 - 5days and allow the batterys to be fully charged, may adopt this strategy at 2wk intervals till funds are available to do more/the weather improves.

i also hv a desulphator hooked permanently to the system

I can second the Prag solution. I have a Prag 5 KW /6.5 KVA running for 4 years now without being switched off except Xmas in office

Handels the LED lights ( 1 .5 KW) laser printers, Photocopiers and one AC without any issue. My earlier SUKAM used to make loud fan noise on the same load and I chose PRAG as the FAN comes on only when boost charging.

The only model I know in market which is rated at 3 times rated surge power

Also, Has a power saving mode so You can throw it in Power saving when not using to allow it to charge batteries when NEPA is available without depleting batteries

But it is also climbed in price now that I checked on Konga 550 K

JUO don't need advert anymore. Just label ur product "JUO" and go to sleep with your two eyes closed.
His prices on konga are splendid. Everyday i set my eyes on the items I got from him, I always wish him well.

Whatever you do, people know and understsnd. Pls don't be tired of doing good.

Thumb up to JUO.


@ GeorgeD..

I hearby promote you to the rank of "Group Captain ".

@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.

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.

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.

NiyiOmoIyunade:
I know you asked specifically for advice about a new energy efficient TV to buy, but I would say you should first sit down and do the math - even an energy efficient TV would consume some watts at the larger screen sizes - say your Plasma is peak 300w consumption and the latest equivalent energy saving OLED is 100w - is a 200w energy saving worth spending 500k to 1million naira on?

If you ran your TV for say 8 hours daily, then you save 200w * 8hours = 1.6kwhr - that is about 70% of the useable power in a good 12v 200ah battery.

Consider doing an energy audit - you might find other power guzzlers you could shave off e.g. fridges and freezers don't really need to run 24/7 so you could put them on a timer overnight OR if you have solar there might be scope for some optimization if you invite a professional to audit your system - with a midpoint spend of 500k,instead of a new TV, you could easily purchase 6pieces 300w Tier 2 panels and have change left for cabling and installation fees OR you could easily purchase 4pieces new 12v 200ah batteries with at least 8kwhr useable power in them OR you could pay your Nepa bills for more than one year OR fuel your generator for at least one year as well.

If however your mind is made up or you just need to have that new OLED TV then by all means go ahead, the outlay is justified by getting your heart's desires but not necessarily the short run energy savings that may accrue - this is especially true if you are using any Renewable Energy power source where your upfront costs are already sunk.

DUNKA:
Good day house,

I currently have a 60 inch LG Plasma TV which is a wattage guzzling monster.

In the market for a more energy efficient model of any brand sized 50 inches and above.

Any advise /pointer would be really appreciated.

Regards

It's a blessing in disguise.
Early this morning, I woke up to see that my overhead water tank stand fell destroying my 2 tanks. It rained heavily yesterday night. The rain was accompanied by heavy wind. Though the concrete stand was not properly constructed and am paying heavily for this. Anyway.. .thats gone
Now I consider this an opportunity to do it better especially when I didn't plan solar water heater in the initial overhead tank stand
I still intend to use concrete with enhanced reinforCement to avert future occurrence.
Now I don't want to rely on what I know basically, I need design ideas from Members.

I am not happy at all as cost of building materials are still not pocket friendly.

Pls keep them coming, sketches and pictures.

See Before and after pictures

Saipro:
That would be ideal but painfully, most irons are rated at 1,500W or over. A lot of them are 1,800W and beyond if they're steam irons.

Mine is a Philips too and is rated 1,000W; I checked just now and I discovered it kicks in at 708W. I don't think one would find an iron at 100W. It would take too long to heat up and the the thermostat might never go off when in use.

Barezzi:
Keep one for me egbon...

pranil:
Looks exactly like Victron BMV 700- I am confused . Does it work on USB cable and victron connect ? or does fangpusun have their own app

chimaaba22:

Maybe u used arithmetics to arrive at your conclusion.

chimaaba22:
Completely off grid.. means more Panel.. sun is not smiling always..
MPPT controller.. 92% efficiency compared to 80% on PWM...
Battery size is 4800wh... Divide by 3hour of average sun recommend panel is 1600Watts...

It is average of 1280 watts.

thats a fair price now, and i just checked their store..they still hv plenty in stock....must be quite disappoiniting....after waiting for so long!!!!
methinks you shud shoot the seller a mail to understand what went wrong

garbamaza:
What's the technical specification of 45a-12/24/36/48v=70k & ANY discount pls.

blazeup:
I will go for Trojan-Re any day.. it's a personal choice based on how robots their RND has evolved over the years..



Mean while :
Please which 250w solar panel brand name would you recommend..?. Base on efficency during low sun light
there seems to be alot out there.

pitodenz:
Thanks bro I have read a lot about both batteries online and I also cam across where Trojan accusing US battery of lying on their cycles
Honestly am looking for someone who have used both batteries to testify cos I don't give a damn about manufacturers competition battle
Meanwhile if I can't get Trojan 6v 410Ah I will go for US battery

Barezzi:
Happy birthday Juo!
I'll call you later today.
